The 10 Most Valuable AI Companies in 2026: Anthropic Leads

Highlights

Anthropic leads at $965 billion (Series H, May 28, 2026).
OpenAI is second at $852 billion; a new round is reportedly being discussed at $1.25 trillion.
xAI is now part of SpaceX after a February 2026 merger that valued xAI at $250 billion.
Waymo ($126 billion) is the only self-driving company in the top five.
Europe's Mistral AI makes the top 10 at more than €21 billion (about $24.4 billion).

The race to build artificial intelligence is also a race for valuations. In just two years, AI model developers have raised money at prices once reserved for listed tech giants.

Industry.co.id ranked the 10 most valuable private AI companies as of November 3, 2026. Each figure is the valuation from the latest funding round or deal announced by the company or reported by a reputable outlet. Listed companies such as Nvidia are excluded.

Quick answer: As of November 3, 2026, the most valuable private AI company is Anthropic ($965 billion, May 2026), followed by OpenAI ($852 billion, March 2026), xAI ($250 billion in its SpaceX merger), Waymo ($126 billion) and Cursor ($60 billion, SpaceX acquisition price). Project Prometheus, Figure AI, Scale AI, Mistral AI and Perplexity complete the top 10.

The Top 10 Ranking

#	Company	Valuation	Round / deal	Date
1	Anthropic	$965 billion	Series H, $65 billion	May 28, 2026
2	OpenAI	$852 billion	$122 billion round	March 31, 2026
3	xAI (now part of SpaceX)	$250 billion	Merger with SpaceX	February 2026
4	Waymo	$126 billion	$16 billion round	February 2, 2026
5	Cursor (Anysphere)	$60 billion	SpaceX acquisition (stock)	Agreed June 16, 2026
6	Project Prometheus	$41 billion	$12 billion round	June 11, 2026
7	Figure AI	$39 billion	Series C, over $1 billion	September 16, 2025
8	Scale AI	Over $29 billion	Meta investment	June 12, 2025

10	Perplexity	$20 billion (reported)	$200 million round	September 2025

Most figures are post-money valuations, meaning the company's value after the new money is added. For xAI and Cursor, the numbers come from deals with SpaceX rather than a standard funding round.

Anthropic and OpenAI: Two Giants Above $800 Billion

Anthropic, the developer of the Claude models, announced a $65 billion Series H on May 28, 2026, at a $965 billion post-money valuation. The round was led by Altimeter Capital, Dragoneer, Greenoaks and Sequoia Capital and included $15 billion of previously committed money from cloud providers, including $5 billion from Amazon. The company is now preparing for an IPO and has filed an S-1 with the US Securities and Exchange Commission.

OpenAI closed a $122 billion round on March 31, 2026, at an $852 billion valuation. SoftBank co-led with Andreessen Horowitz, D.E. Shaw Ventures, MGX, TPG and T. Rowe Price, with Amazon, Nvidia and Microsoft also taking part. About $3 billion came from retail investors.

The order may change soon. CNBC reported on October 31, 2026, citing the Financial Times, that OpenAI is now seeking up to $20 billion at a $1.25 trillion post-money valuation. That round has not closed.

xAI, Waymo and Cursor: Three Different Paths

xAI, Elon Musk's AI company, no longer stands alone. In February 2026 it merged with SpaceX in a deal that, according to CNBC, valued the combined company at $1.25 trillion: $1 trillion for SpaceX and $250 billion for xAI. xAI had been valued at about $230 billion in a $20 billion round in January 2026. SpaceX then listed on Nasdaq on June 12, 2026.

Waymo, Alphabet's self-driving unit, raised $16 billion on February 2, 2026, at a $126 billion post-money valuation, led by Dragoneer, DST Global and Sequoia Capital.

Cursor, the AI coding tool made by Anysphere, agreed to be acquired by SpaceX in a $60 billion stock deal in June 2026, according to TechCrunch. Because it is paid in stock, its value moves with SpaceX shares.

The Next Five: Robots, Data and Europe

Project Prometheus ($41 billion): backed by Jeff Bezos to build AI for engineering in the physical world, it raised $12 billion in June 2026 from investors including JPMorgan Chase, Goldman Sachs and BlackRock.
Figure AI ($39 billion): the humanoid robot maker closed a Series C of more than $1 billion led by Parkway Venture Capital, with Nvidia, Intel Capital, LG Technology Ventures and Qualcomm Ventures participating.
Scale AI (over $29 billion): the AI training data provider was valued in June 2025 when Meta took a minority stake.
Mistral AI (over €21 billion): France's AI champion closed a €3 billion Series D led by Samsung Electronics.
Perplexity ($20 billion, reported): the AI search engine, according to The Information as cited by TechCrunch in September 2025.

Who Is Not on the List Yet

Some figures circulate widely but could not be verified from primary or reputable sources, so they are left out of the table:

Databricks is reported to be worth about $190 billion after an August 2026 round. If confirmed, it would rank third or fourth.
Safe Superintelligence (SSI), Moonshot AI and HUMAIN appear in several valuation lists, but we could not find their figures in official announcements or reputable outlets.
Thinking Machines Lab, founded by Mira Murati, was valued at $12 billion in July 2025. Reports of a new, higher round are still talks.

What It Means for Industry

Valuations this high reflect how expensive AI is to build, especially data centers and chips. Anthropic's IPO filing, for example, lists about $895.4 billion in purchase commitments and leases, almost all of it for compute and infrastructure.

The list also shows that AI is no longer just chatbots. Humanoid robots (Figure AI), self-driving cars (Waymo), coding tools (Cursor) and AI for physical engineering (Project Prometheus) now attract tens of billions of dollars, close to the manufacturing and automotive sectors.

Beyond the two giants, investor money is flowing to AI that touches the real world: robots, self-driving cars and industrial engineering.
