AI Companies Ranked by Valuation: Two Hold 89% of the Value

The four valuations total $2,031.4B. Anthropic's $965B is 47.5% of it and OpenAI's $852B is 41.9%, so the two hold $1,817B, or 89.4%. Databricks at $190B takes 9.4% and Mistral AI at about $24.4B takes 1.2%. Without Databricks, the two hold 98.7% of the three model developers' combined value.

First to fourth is a 39.6x gap, and the axis is linear on purpose. Mistral's bar is about 2.5% of Anthropic's, and that near-invisibility is the finding: on a logarithmic axis, $24B and $965B would look like neighbours. Because Mistral's figure is a floor, the true gap is smaller than 39.6x.

Wider nets change little. Add three older press-reported marks, Safe Superintelligence at $32B, Perplexity at $20B and Thinking Machines Lab at $12B, all 13 to 18 months old, and the top two still hold 86.7%.

Anthropic leads OpenAI by $113B, a ratio of 1.13x, but the marks are not from the same day. OpenAI announced $852B on 31 March 2026, when Anthropic's last announced valuation was $380B (12 February), 2.2x lower. On 28 May, eight weeks later, Anthropic announced $965B.

Both trajectories are steep. Anthropic went from $61.5B on 3 March 2025 to $183B on 2 September 2025, $380B and then $965B, a 15.7x rise in 14.8 months. OpenAI went from $157B in October 2024 to $852B, 5.4x in about 18 months.

Neither mark is final. Bloomberg reported on 29 September 2026 that OpenAI is in talks to raise about $30B at about $1.4T, which would put it first again, though talks are not a closed round. OpenAI is also reported to be targeting a fourth-quarter 2026 listing at up to $1T, and an Anthropic listing could reprice both.

Databricks announced a valuation of $190B on 13 August 2026 with a $5B strategic round, and did not say whether it is post-money. It calls itself "the Data and AI company", but it sells a data platform rather than a model or an AI assistant, so the ranking labels it a platform, not a model developer.

The choice changes the arithmetic, not the conclusion. With Databricks, the top two hold 89.4% and Databricks is third at 9.4%. Without it, Mistral AI moves up to third and the top two hold 98.7%. Both are given because either treatment is defensible.

Mistral AI announced a €3B Series D at a post-money valuation of "more than €21B", a lower bound rather than a point estimate. At the ECB reference rate of 1.1614 dollars per euro on 8 September 2026, that is about $24.4B, so the dollar figure is a floor too.

Floors recur in this field: Anthropic said its run-rate "crossed" $47B and Databricks said it "crossed" $7B. Mistral's release gave no revenue figure, so it is the one company here with no valuation-to-revenue multiple.

A valuation here is what investors agreed to pay for a stake in a private round, as the company states it. No public market trades these shares, so nothing resets the figure between rounds, and it says nothing about what a company earns or could be sold for.

Headlines carry qualifiers. OpenAI's $122B is "committed capital", not cash received. Of Anthropic's $65B, $15B was previously committed by hyperscalers. OpenAI's earlier headline for the same round was pre-money, which leaves out the new money and is not comparable with the closing post-money $852B. Databricks said only "valuation".

Three of the four companies stated a revenue figure alongside their valuation. Anthropic said its run-rate revenue "crossed $47 billion" in May 2026, which puts its valuation at 20.5x run-rate. Databricks said it "crossed" a $7B run-rate, giving 27.1x. OpenAI's announcement gave a monthly figure of $2B, which annualises to $24B and gives 35.5x.

Read the multiples with care. "Crossed" is a floor, so Anthropic's 20.5x and Databricks' 27.1x are upper bounds. OpenAI's 35.5x rests on our own annualisation of a monthly figure, not a stated run-rate. A run-rate is a short period multiplied up, not a year of revenue.

No audited numbers sit behind any of this. Anthropic announced a confidential draft S-1 on 1 June 2026, and OpenAI has also filed confidentially, per Bloomberg Law on 9 June 2026. A public S-1 would carry audited figures and could replace most of this context within weeks.

Four names often appear in lists like this one. Each carries a figure that is a different kind of number from the four ranked.

xAI is quoted at about $230B in press reports, but SpaceX absorbed it on 2 February 2026, so no standalone valuation exists. Its own Series E release on 6 January 2026, for $20B, stated none. SpaceX has traded on Nasdaq as SPCX since 12 June 2026.

Cerebras is usually cited at about $95B, but that is a public market capitalisation, and reports of its debut ranged from roughly $67B on shares outstanding to about $86B fully diluted to the $95B widely quoted. The stock began trading on Nasdaq on 14 May 2026 and its value changes with every trade, whereas a private valuation is fixed once, in a round. One number, three bases, moving daily: that is why it is not on the ranking.

Scale AI's $29B comes from Meta's June 2025 purchase of a 49% non-voting minority stake for $14.3B, which Scale said valued it at $29B (Reuters, 13 June 2025). It is implied by a deal rather than set by a priced round, and it is 16 months old.

Perplexity's $20B is a September 2025 press report from The Information, relayed by Reuters, not a company announcement, and it is 13 months old. Since 2 September 2025 Anthropic's announced valuation has risen 5.3x, from $183B to $965B, so a mark from then cannot sit beside 2026 marks.

What it settles: two companies stand at $965B and $852B and the other two at $190B and about $24.4B, a first-to-fourth gap of at most about 40x. The top two hold 89.4% of the combined value, or 98.7% without Databricks, whichever of them is first.

What it does not settle: which of the two is larger today, what any of the four earns, or what a public market would pay. OpenAI's reported talks near $1.4T, a public S-1 from either company or an Anthropic listing would each change the figures. Which AI creators score highest on capability is a different question.
