CAC 40 and Nasdaq Top 10: size does not tell you AI maturity

CAC 40 Nasdaq market capitalisation AI maturity AI governance AI Act index concentration Magnificent Seven NVIDIA LVMH where value accrues financial literacy

By Paul-Antoine TUAL, AI Transformation Leader, Croissance et Transitions, July 2026.

Framing. There is only one leaderboard for large companies: market capitalisation. Yet it measures one thing only, what the market is willing to pay today. We wanted to build a second one, measuring what those same companies really know how to do with artificial intelligence internally: their AI maturity. So we took the ten largest CAC 40 and Nasdaq companies and scored them from 1 to 5 across eight dimensions, on public evidence only. Then we set the two readings side by side, line by line. They have almost nothing in common: NVIDIA, the world’s largest company and king of AI chips, is only 9th out of 10 on the Nasdaq’s AI maturity; L’Oréal, only 2nd in the CAC 40 by size, is 1st by maturity; and not one of the twenty companies analysed reaches the grid’s highest level. Market-cap figures are as of 20 July 2026; the maturity study is dated at its source. This article is not an investment note: it is a reading lesson.

First, AI maturity: the question market cap never asks

Let us start with the less familiar of the two criteria, because it carries this article’s thesis.

A company’s AI maturity is its ability to make artificial intelligence work internally, end to end: a funded and steered strategy, governance that answers for its decisions, data whose provenance is known, a technical platform that holds up in production, employees trained and involved, use cases genuinely deployed on core processes, mapped risks and compliance that holds. It is an internal execution capability, not a balance-sheet size.

Two confusions to clear up straight away, because they explain most of the surprises that follow:

  • Selling AI ≠ knowing how to govern it. A company can make the chips the planet runs on and still have, internally, no AI committee, no training plan and no governance of its own training data. That is exactly NVIDIA’s case.
  • Communicating about AI ≠ being mature on AI. A claim is not proof: in the grid, an unsupported statement does not lift the score, and a proven gap between promise and product is paid for (Apple, a $250 million settlement over Siri in May 2026).

The result fits in one table. Here, for each index, is the podium by size and the podium by AI maturity, both criteria applied to the same ten companies.

IndexPodium by sizePodium by AI maturity
CAC 40LVMH · L’Oréal · HermèsL’Oréal · Sanofi · Schneider Electric
NasdaqNVIDIA · Apple · AlphabetAlphabet · Meta · Amazon

On each side, only one name survives the change of criterion: L’Oréal in Paris, Alphabet in New York. Hermès, France’s third-largest company, drops to 10th and last on maturity; NVIDIA, the world’s largest, to 9th. Three figures complete the picture: the CAC 40 Top 10 averages 3.05/5, the Nasdaq 3.16/5 (both panels at the same “Structured” level), and not one of the twenty companies reaches the Transformative level [12].

This deserves to be stated plainly for an SME or mid-cap leader. The twenty largest companies in both indices are not, on AI, light-years ahead. Most are in the same place as many mid-sized companies: use cases running, governance that exists on paper, and proof that is missing. The gap is not where you think it is. The lead is won on proof.

The rest reads in three steps: the maturity grid, detailed dimension by dimension; the two indices put through that grid, each company read on both its score and its market cap; and finally what overlaying the two says about where the value is going.

The analysis grid, dimension by dimension

Eight dimensions, each with a weight. The weighting reflects a methodological conviction: a company with neither strategy nor governance is not doing AI, it is running experiments. That is why D1 and D2 together carry 30% of the score. At the other end, communication carries only 10%: it is a symptom, not a capability.

Dimension (weight)The question askedWhat lifts the scoreWhat caps it
D1 · Strategy and value creation (15%)Is AI a steered, funded, quantified strategic priority?A published roadmap, an identified budget, a dated value target (BNP Paribas targets €750 million a year; Alphabet guides to $180-190 billion of capex)AI everywhere in corporate communication but absent from the investor presentation (Safran, Airbus)
D2 · Governance and accountability (15%)Who answers for AI, and how far up does the board go?A dedicated committee that actually meets, a Chief AI Officer, a framework aligned to a recognised standard (NIST AI RMF, ISO/IEC 42001), board reporting; Schneider Electric and its Digital Committee (7 meetings a year)A charter announced but never published, no anchoring at board level, or “trustworthy AI” principles aimed at customers rather than at oneself (NVIDIA)
D3 · Data (12%)Do you know where the data comes from, and can you prove it?A group-level data catalogue, quality indicators, traceability and lawfulness of training dataA platform claimed without a single public indicator (the general case), let alone active litigation over data provenance (NVIDIA, Meta)
D4 · Technology and industrialisation (12%)Can you run AI in production, not just in a demo?A documented MLOps platform, robustness testing, red teaming, incidents disclosed and fixed (Microsoft, Amazon)No documented drift monitoring or rollback procedure; pilots that never scale
D5 · Talent, culture and organisation (12%)Are employees trained and involved, and does labour dialogue exist?A quantified training plan and a signed labour agreement: Safran (AI agreement of 22 January 2026 with CFDT, CFE-CGC and FO; 43,716 employees trained)Training on display but labour dialogue absent or contested (Airbus/CFE-CGC, Schneider/CFDT), job cuts left undiscussed
D6 · Deployment and realised value (12%)How many use cases in production on core processes, for what measured value?Usage at scale on the core business, with published indicators (Alphabet: 900 million monthly users on Gemini)Value announced but never third-party audited: the case for almost the entire panel
D7 · Risk, compliance and internal control (12%)Are AI risks mapped, systems classified, the AI Act prepared for?An AI risk factor formalised in regulated filings, an assumed public position on the AI Act, a system inventoryGeneric risk management in which AI is not a standalone category; no risk map published three weeks before the 2 August 2026 deadline
D8 · Financial, extra-financial and stakeholder communication (10%)Is AI in the equity story, with figures that hold?AI indicators published every quarter (Alphabet, Amazon), including the costs owned up to (electricity consumption)A gap between promise and product, penalised (Apple, $250 million over Siri), or total silence (Hermès: zero mention of AI in its FY2025 results)

The five levels, and the ceiling nobody has broken

The overall score is the weighted average of the eight scores. It reads on five levels:

LevelScoreWhat it describesCount (out of 20)
Emerging< 1.8AI is still a watching brief, with no identified use0
Exploratory1.8-2.5Early uses, nothing steered or governed1 (Hermès, 2.15)
Structured2.6-3.4Governance exists, use cases are running, the proof is missing13
Integrated3.5-4.2AI is in the core processes and in the accounts6
Transformative> 4.2AI redefines the business model, governance keeps pace0

This may be the single most important number in the study: not one of the twenty largest companies in either index reaches the level the grid describes as the end state. The panel’s best score, Alphabet, tops out at 3.91, Integrated, not Transformative. Thirteen of the twenty remain at the Structured level, where a great deal has already been done but cannot yet be proven.

The mechanism that makes the grid defensible: the evidence level

Beyond the number, every score carries an evidence level: documented (a cited public item establishes it), declarative (the company asserts it, nothing attests to it), mixed, or absent. Three rules follow from this, applied without exception to all twenty companies:

  1. Any score ≥ 3 requires cited public documentary proof, with its source. No source, no 3.
  2. Where the narrative and the proof diverge, the lower score is kept. That is what holds TotalEnergies at 2 on data despite very real technology partnerships, its CEO having himself described progress, in September 2025, as “bits and pieces”.
  3. Without proof, the score stays low rather than being guessed (1 or 2, evidence level “absent”). Never an estimate in place of a fact.

It is this mechanism, not an opinion, that produces the ranking reversals. It has one assumed side effect: it penalises discretion. A low score there means “no public proof”, which is not quite “no initiative”, a nuance worth keeping in mind for the two tables that follow.

What the grid does not measure

Method note. To be read before the rankings: the full methodology calls for a 4-to-6-week campaign combining internal document review, 12 to 20 targeted interviews (executive management, finance, IT/data, HR, legal, internal audit, business lines, board secretariat) and tool demonstrations. This edition mobilised no interviews and no internal documents: it relies solely on public sources (universal registration documents, annual and sustainability reports, 10-K/20-F filings, proxy statements, investor transcripts, specialist press), consulted on 13-14 July 2026 [12]. An assumed consequence: dimensions with high public exposure (D1, D2, D7, D8) are mechanically better documented than internal dimensions (D3 Data, D4 Technology, D5 Talent), regardless of these groups’ real maturity. These results therefore measure AI maturity as publicly documented: a starting point for prioritising checks, not a verdict.

Why eight dimensions here, and nine in the MATIA Method™? The MATIA Scale™ we use in SME and mid-cap diagnostics has nine dimensions and five levels (from Spectateur to Pionnier); it feeds on interviews and internal access. Four of those dimensions, model sovereignty, resilience, technical debt and security score, simply cannot be read in a universal registration document: this “listed company” edition absorbs them into technology and risk. In return, it isolates two dimensions specific to the listed world, data and financial communication, precisely because the obligation to publish creates verifiable proof there. Same backbone, a lens adapted to what a listed company must make public.


The CAC 40 through the grid: what size does not predict

Here are the ten largest companies in the Paris index, ranked by their AI maturity, no longer by market cap, which sits alongside so the two can be compared line by line.

Two words to read the table. An index is a basket of stocks representative of a market: the CAC 40 groups 40 of the largest companies listed in Paris (Euronext). Market capitalisation is the share price multiplied by the number of shares, the “value” the market assigns at a given moment. Neither says anything about AI maturity: that is exactly what this table puts to the test.

Maturity scores: Croissance & Transitions in-house study “AI Maturity: CAC 40 Top 10”, 13 July 2026, on public sources [12]. Market caps: CompaniesMarketCap as of 20 July 2026, converted from US dollars at the day’s rate (€1 ≈ $1.14) and rounded [1][11]. Prices move daily; the L’Oréal-Hermès contest for 2nd place by size is tight and can flip depending on source and day.

Figure 3 below links each company to its two ranks, read in the same direction.

Rank by size compared with rank by AI maturity, CAC 40 Top 7 by maturity Slope chart linking, for the CAC 40's seven largest companies by AI maturity, their rank by market cap to their rank by maturity: Sanofi moves from 10th to 2nd place, LVMH falls from 1st to 7th.

Figure 3. Sanofi leaps from 10th to 2nd place, LVMH falls from 1st to 7th: size does not predict the maturity rank. Source: MATIA AI maturity grid, data as of 20 July 2026.

Read the two columns together: they contradict each other almost everywhere. L’Oréal, only 2nd by size, is 1st by AI maturity: a dedicated AI presentation at its AGM, a tech/AI budget above its R&D budget, a responsible-AI framework since 2021. Sanofi is the clearest demonstration: last of the Top 10 by market cap, at €92 billion against LVMH’s €240 billion, it is second by maturity, calls itself an “AI-powered biopharma” and runs an AI tool inside a phase-3 clinical trial. Conversely, LVMH, the index’s largest company, falls to 7th on maturity, and Hermès, third by size, comes dead last: at the maker of the silk scarf, AI is nearly absent from financial communication, a discretion consistent with its brand culture, but which, absent public proof, is paid for in the grid.

Sector predicts no better than size. Luxury and beauty (LVMH, L’Oréal, Hermès) together account for nearly 40% of the Top 10 by market cap, and occupy ranks 1, 7 and 10 on AI maturity. Three houses from the same universe, at opposite ends of the ranking. As for the index’s most “technological” company, Schneider Electric, it comes only third, and that is electrification and automation, not software: no software, cloud or AI champion appears at the top of the CAC 40. Keep that in mind; it takes on its full meaning against the Nasdaq.

The LVMH lesson: three rankings, three different answers

LVMH deserves a pause, because it occupies three distinct ranks depending on what is measured: 1st by size, 3rd by index weight, 7th by AI maturity.

The second rank is explained by the free float, that is, the share of stock actually available to buy once the blocks durably held by a family, a founder or a state have been stripped out. In February 2026, the Arnault family crossed the 50.01% threshold of LVMH’s capital (and nearly 66% of voting rights), according to a filing with the French financial markets authority (AMF) dated 25 February 2026 [4]. Barely half of LVMH’s shares therefore “float” on the market. Since an index weighting is calculated on free-float market cap, LVMH weighs far less in the index than its raw size: as of 12 March 2026, the CAC 40 was led by Schneider Electric (8.25%) and TotalEnergies (8.11%), with LVMH coming only in third position (6.94%) [3].

Keep the triple distinction, it is the thread running through this whole article: size measures what the company is worth, weight measures how much of it the market can actually trade, and maturity measures what it can do with AI. None of the three follows from the other two.

The Nasdaq through the grid: the AI sellers are not the most mature

Same exercise on the other side of the Atlantic, and the same layout: AI maturity first, market cap alongside.

Maturity scores: Croissance & Transitions in-house study “AI Maturity: Nasdaq Top 10”, 14 July 2026, on public sources, January 2026 scope [12]. Market caps: CompaniesMarketCap as of 20 July 2026 [2]. Micron (≈ $1.0 trillion, having joined the trillion-dollar club in Q2 2026 [9]) and AMD (≈ $840 billion) have since overtaken ASML and Netflix in the Top 10 by size: as new entrants, they have not yet been scored. Also worth noting, SpaceX, listed on the Nasdaq on 12 June 2026 and valued at around $1.6 trillion, is listed without (yet) being a Nasdaq-100 constituent [2][10]: being listed on a venue is not the same as being a member of an index.

The first four lines tell a coherent story: these are AI users (Alphabet, Meta, Amazon, Microsoft), the only ones in the panel to reach the Integrated level. Then the ranking drops away, exactly where the market pays the most.

Apple and NVIDIA are fighting over the world’s largest market cap, at around $5 trillion. NVIDIA was the first company in history to cross that mark, even passing $5.5 trillion in mid-May 2026 [5], and Apple briefly took back the top spot on 17 July 2026 [6]. These two sit at the 7th and 9th ranks of their own index’s AI maturity. Perhaps the most telling comparison is this one: the ten largest Nasdaq stocks weigh about nine times the entire CAC 40 [2], for an average maturity score of 3.16 against 3.05. Nine times the market value, eleven hundredths of a point of maturity.

The finding: the pick-and-shovel sellers are the dunces of the class

Here is the most counter-intuitive result of the whole study. NVIDIA, the world’s largest company and supplier of silicon to the entire industry, is only 9th out of 10 on the Nasdaq’s AI maturity. Broadcom brings up the rear.

This is not an anomaly: it is exactly what the grid is built to reveal. It measures a company’s ability to govern AI at home, not the quality of the AI it sells to its customers. Yet NVIDIA, at the date of the analysis, has no dedicated AI committee, no structured AI training plan for its tens of thousands of employees, and faces active litigation over training data [12]. Selling AI and knowing how to govern it are two different jobs, and the two are not correlated.

The mirror of this finding: Alphabet, only 3rd by size, is 1st by maturity (Gemini at 900 million monthly users, a top score in both strategy and deployment, a double full mark it shares only with Meta); Apple, 2nd by size, is only 7th by maturity, dragged down by a proven case of AI-washing, a $250 million settlement in May 2026 for misleading communication about Siri’s capabilities [12].

One last case is worth the detour, because it bridges the table’s two columns. Microsoft has fallen below $3 trillion, behind Alphabet, which crossed $4 trillion as early as January 2026 [7]. In 2026 the market stopped crediting AI spending blindly: it now demands to see it turn into revenue. The same capex billions read as an asset at Alphabet, its in-house TPU chips, its Gemini model, and as a reason for caution at Microsoft, whose AI architecture rests largely on its partner OpenAI, currently renegotiating [8]. The market is starting, in its own way and with its own instruments, to score maturity.

Box. The Top 10 moves. Our maturity study froze the Nasdaq Top 10 in January 2026: ASML (a semiconductor-equipment maker) and Netflix then held the 9th and 10th places by size. Six months later, carried by the Q2 2026 chip rally, Micron and AMD overtook them. It is a live demonstration that a “Top 10” is a moving target: between two snapshots, two names out of ten have already changed. The maturity scores above apply to the January scope.

Dimension by dimension: what the grid really reveals

The overall score hides what matters most. It is by going down to the eight dimensions that the two panels diverge, and that the surprises appear. Here is each dimension’s average across the ten companies of each index (computed from the studies’ detailed scores [12]).

DimensionCAC 40 averageNasdaq averageGap
D1 · Strategy3.33.6Nasdaq +0.3
D2 · Governance3.23.2tie
D3 · Data2.42.1CAC 40 +0.3

D6 · Deployment3.33.8Nasdaq +0.5
D7 · Risk / compliance2.73.3Nasdaq +0.6
D8 · Communication3.23.4Nasdaq +0.2

Four lessons come out of it.

1. Data is the general blind spot, and the two indices’ only common ground. D3 is the weakest dimension in both panels, the only one below 2.5 on both sides (2.4 for the CAC 40, 2.1 for the Nasdaq, the lowest score in the whole study). All claim a unified data platform, none publishes a quality or traceability indicator for its training data. This is no longer just an artefact of under-communication: at NVIDIA as at Meta, it is an active dispute over data provenance.

  1. The Nasdaq pulls ahead where AI is the product. D6 Deployment (3.8 against 3.3) and D1 Strategy (3.6 against 3.3): when generative AI is directly your growth engine, the value created is visible, quantified and published every quarter. For an industrial or luxury group, AI remains an internal transformation lever, harder to document, and often absent from the equity story.

3. The French surprise: labour dialogue. D5 Talent is the only dimension where the CAC 40 clearly beats the Nasdaq, 3.1 against 2.4, the widest gap in the study (its only other lead is on D3, by 0.3 point, and from the bottom). On one side, signed labour agreements (Safran, January 2026) and quantified training plans (L’Oréal, Sanofi); on the other, an aggressive AI narrative coexisting almost everywhere with documented waves of job cuts (Microsoft, Meta, Tesla, Amazon). French labour law and the presence of employee representative bodies in AI transformation are not just a constraint: in this grid, they produce proof, and therefore score.

  1. The compliance paradox. One would expect the opposite, but it is the Nasdaq that leads the CAC 40 on D7 Risk and compliance (3.3 against 2.7), even though the European AI Act applies first and foremost to Europeans. The explanation is mechanical: American companies detail their AI risks in their 10-K filings and have taken clear public positions on the EU’s GPAI Code of Practice (Alphabet, Microsoft and Amazon signed; Meta alone refused). On the CAC 40 side, not one of the ten has published an AI risk map or a classification plan for its systems, while the obligations applicable to high-risk systems take effect on 2 August 2026 [13], less than three weeks after the study’s date. Being subject to a rule and being able to prove you are preparing for it are two different things.

Where is the value going?

Overlay the two readings and a thesis emerges, consistent with what we argue in Where is AI’s value going?. Three takeaways for a business leader.

Market value has gone to AI infrastructure; maturity lies elsewhere. Those who top the market-cap ranking are the sellers of the underlying layer: chips, cloud, models. Yet under the lens of internal governance, it is the AI users, Alphabet, Meta, Amazon, L’Oréal, Sanofi, who lead, not the sellers of silicon. The lesson for an SME is therefore not “buy this or that stock”: that would be a misreading, and it is not our job. It comes down instead to one sentence: “become a company that uses AI with maturity”: strategy, governance, clean data, use cases in production, compliance. That is exactly the path described in our white paper on industrialising AI.

The market no longer rewards the announcement; it rewards the proof. Microsoft back below $3 trillion for failing to turn its capex into revenue, Apple fined $250 million for an unkept AI promise: the penalty, financial or legal, now falls on unproven claims. The grid says the same thing at the micro scale: a score ≥ 3 without public proof does not exist. Proof is read in the facts, not in the slogans. This is true for a Nasdaq giant as much as for a mid-cap in the Drôme.

Sovereignty is not a slogan, it is a reading of these tables. That Europe has no chip or cloud champion in the world Top 10, the only European in the Nasdaq panel, ASML, being an equipment maker, not an AI-software player, is a strategic fact. Depending on an AI infrastructure listed 6,000 kilometres away, billed in dollars and subject to other rules, is a supply-chain risk that can be managed: data hosting in Europe, open models that run locally, vendor reversibility. We developed this point in Digital sovereignty.

How to read these two rankings without falling into traps

  • A market cap is a snapshot, not a truth. NVIDIA and Apple swapped the world’s number-one spot several times in 2026; ASML and Netflix left the Nasdaq Top 10 within six months. Always date the figure.
  • A big market cap ≠ a good investment, and size ≠ AI maturity. Market cap measures what the market already pays; maturity, the ability to govern AI; neither predicts a share price.
  • Weight in the index ≠ size (the LVMH reminder), and index membership ≠ world ranking (the SpaceX and ASML reminders).
  • The maturity measured here is public, not audited. It mechanically under-scores internal dimensions; a low score can reflect discreet communication (Hermès) as much as a genuine lag.
  • A score is always read together with its evidence level. A 2 can mean “does not do it” or “does not publish it”: the grid explicitly distinguishes the two (documented, declarative, absent). That is what makes it arguable line by line, and therefore useful.

[12] Croissance & Transitions, in-house studies “AI Maturity, CAC 40 Top 10” (13 July 2026) and “AI Maturity, Nasdaq Top 10” (14 July 2026), the same methodology applied identically to both panels. Proprietary grid derived from the MATIA Method™: 8 weighted dimensions (D1 Strategy and value creation 15% · D2 Governance and accountability 15% · D3 Data 12% · D4 Technology and industrialisation 12% · D5 Talent, culture and organisation 12% · D6 Deployment and realised value 12% · D7 Risk, compliance and internal control 12% · D8 Financial, extra-financial and stakeholder communication 10%), scored from 1 to 5 with an evidence level attached (documented / declarative / mixed / absent), the weighted overall score read on 5 levels (Emerging < 1.8 · Exploratory 1.8-2.5 · Structured 2.6-3.4 · Integrated 3.5-4.2 · Transformative > 4.2). The per-dimension averages quoted in the article are calculated from both studies’ detailed scores. Scoring built exclusively on public sources: universal registration documents, annual and sustainability reports, SEC 10-K / 20-F filings, DEF 14A proxy statements, investor transcripts, specialist press. Includes the documented AI-washing cases (Apple’s $250 million Siri settlement, May 2026; Tesla’s FSD statistics challenged by a Reuters investigation) and public positions on the AI Act (Alphabet, Microsoft, Amazon signatories of the GPAI Code of Practice; Meta’s refusal).

Frequently asked questions

What is a company's AI maturity?
It is its ability to make artificial intelligence work internally, end to end: a funded and steered AI strategy, governance that answers for its decisions, data whose provenance and quality are known, a technical platform that holds up in production, employees trained and involved, use cases actually deployed on core processes, mapped risks and compliance that holds. AI maturity follows neither from a company's size nor from the fact that it sells AI to others: a company can make the chips the planet runs on and still have, internally, no AI committee, no training plan and no governance of its own training data.
How is AI maturity measured here?
With a proprietary grid derived from the MATIA Method™, which scores each company from 1 to 5 on eight weighted dimensions (strategy 15%, governance 15%, data 12%, technology 12%, talent 12%, deployment 12%, risk/compliance 12%, communication 10%), then derives an overall score and a level: Emerging (<1.8), Exploratory (1.8-2.5), Structured (2.6-3.4), Integrated (3.5-4.2), Transformative (>4.2). Each score also carries an evidence level: documented, declarative, mixed or absent. A crucial methodological point: this edition relies solely on public sources (registration documents, annual reports, 10-Ks, investor transcripts) consulted in mid-July 2026, with no internal interviews. It therefore measures AI maturity as publicly documented, not a full audit. Every score ≥3 is backed by a cited public proof, and where the narrative and the proof diverge, the lower score is kept.
Does being big on the stock market mean being mature on AI?
No: this is the most counter-intuitive finding of this study. Scoring the internal AI maturity (governance, data, deployment, compliance) of the ten largest companies in each index produces a ranking with almost nothing in common with the ranking by market cap. NVIDIA, the world's largest company and undisputed king of AI chips, comes only 9th out of 10 on the Nasdaq's AI maturity; Broadcom brings up the rear. In Paris, LVMH, the CAC 40's largest company, is only 7th out of 10, and Hermès, third by size, comes last. The reason: selling AI, or being worth a lot, and knowing how to govern AI internally are different things. The grid measures the latter.
What is large companies' weakest AI dimension?
Data. Across the twenty companies analysed, the 'Data' dimension is the worst-scored in both panels: an average of 2.4/5 for the CAC 40 and 2.1/5 for the Nasdaq, the only dimension below 2.5 on both sides. All claim a unified data platform, none publishes a quality or traceability indicator for its training data, and several face active litigation over its provenance. A second finding: not one of the twenty reaches the grid's top level (Transformative), and only six reach the Integrated level.
What are the 10 largest CAC 40 companies, and their AI maturity?
As of 20 July 2026, by market cap: LVMH (≈ €240 billion), L'Oréal (≈ €202 billion), Hermès (≈ €176 billion), TotalEnergies (≈ €158 billion), Airbus (≈ €151 billion), Schneider Electric (≈ €150 billion), Safran (≈ €135 billion), BNP Paribas (≈ €113 billion), Air Liquide (≈ €113 billion) and Sanofi (≈ €92 billion). Scored on AI maturity, those same ten companies fall into a completely different order: L'Oréal 1st (3.64/5), Sanofi 2nd (3.51) despite being tenth by size, Schneider Electric 3rd, then Safran, Air Liquide, BNP Paribas, LVMH and TotalEnergies tied, Airbus, and Hermès last (2.15). No software or AI champion appears at the top of the Paris index, and a sector's size does not predict its maturity.
What are the 10 largest Nasdaq companies, and their AI maturity?
Within the Nasdaq-100, by market cap as of 20 July 2026: NVIDIA (≈ $5.0 trillion), Apple (≈ $4.8 trillion), Alphabet/Google (≈ $4.3 trillion), Microsoft (≈ $3.0 trillion), Amazon (≈ $2.7 trillion), Broadcom (≈ $1.8 trillion), Meta (≈ $1.6 trillion), Tesla (≈ $1.4 trillion), Micron (≈ $1.0 trillion) and AMD (≈ $840 billion), four of them chipmakers. On AI maturity the order almost inverts: Alphabet 1st (3.91/5), Meta 2nd, Amazon 3rd, Microsoft 4th, then Netflix, ASML, Apple 7th, Tesla, NVIDIA 9th and Broadcom 10th. The maturity ranking covers the January 2026 scope: Micron and AMD, which have since entered the Top 10, have not yet been scored.
Is this ranking investment advice?
No. This article is educational and informational: it explains how to read two indices in the light of their largest companies' AI maturity, and what that reading reveals about the economy in 2026. It is neither investment advice nor a buy/sell recommendation. A high market cap says nothing about how good an investment is at a given price, an AI-maturity score is not a price forecast, and past performance does not predict future performance. For any investment decision, consult a licensed adviser.
