Highest Valued AI Companies 2026: Every Private AI Startup Worth $10B+

Anthropic is the highest-valued private AI company in the world at $965 billion, set by its $65 billion Series H round on May 28, 2026 — edging out OpenAI's $852 billion. That's the short answer. The longer answer is that these two labs alone are worth more than most entire stock market sectors, and the next eight companies on the list tell you where the rest of the AI capital is actually flowing.

Private AI valuations have moved so fast in 2026 that lists compiled even three months ago are already stale. Anthropic's valuation alone nearly tripled between February and May. We track every major round as it closes, and this is the full, sourced ranking of the 10 highest-valued private AI companies as of July 2026 — with the caveat that SpaceX, formerly on every list like this after absorbing xAI, is now excluded because it completed its IPO on June 12, 2026.

Highest Valued AI Companies 2026: The Full Ranking

As of July 2026, the highest valued private AI company is Anthropic at $965 billion, followed by OpenAI at $852 billion, Databricks at $134 billion, Waymo at $126 billion, and Anduril at $61 billion. These five alone account for roughly $2.14 trillion in combined private valuation — more than the GDP of most G20 economies — and the gap between the top two and everyone else has never been wider.

Figures are July 2026 estimates blended from company press releases, Bloomberg, CNBC, TechCrunch, and Tracxn funding data. Scale AI and Mistral figures reflect the most recent confirmed or in-progress round; both were in active fundraising discussions as of publication.

How Anthropic Overtook OpenAI

Anthropic's ascent is the fastest valuation climb of any company this size in venture history. It raised at $380 billion in February 2026, then $965 billion just three months later in a Series H co-led by Capital Group, Coatue, D1 Capital Partners, GIC, ICONIQ, and XN, with $15 billion of previously committed hyperscaler capital — including $5 billion from Amazon — folded in. That's a 154% jump in a single quarter, driven by an annualized revenue run rate that crossed $47 billion by mid-May 2026, more than double what it was six months earlier.

OpenAI's $852 billion valuation came from a $122 billion round that closed in late March 2026, a 70% jump from the $500 billion mark set by an October 2025 employee tender offer. Amazon put in $50 billion of that round, with Nvidia and SoftBank each contributing $30 billion. OpenAI's own annualized revenue sits closer to $25 billion — smaller than Anthropic's — which is why Anthropic's implied revenue multiple (roughly 21x) is actually lower than OpenAI's (roughly 34x) despite the larger absolute valuation. Neither number should be read as "which company is better" so much as "which growth curve investors are pricing more aggressively right now."

We break down the full mechanics of how these multiples get set, including the enterprise contract data behind them, on our AI valuations dashboard, which tracks foundation-model pricing alongside the broader private AI market.

Why SpaceX Is No Longer on This List

Every "highest valued AI companies" list published between February and May 2026 had SpaceX near the top, because SpaceX absorbed xAI in a stock-swap merger announced February 2, 2026 that valued the combined entity at $1.25 trillion — roughly $1 trillion for SpaceX and $250 billion for xAI. That combination briefly made it the single most valuable private company on earth, AI or otherwise.

It didn't stay private long. SpaceX completed the largest IPO in history on June 12, 2026, pricing at a $1.77 trillion valuation and closing its first trading day around $2.1 trillion in market cap — the sixth most valuable U.S.-listed company. Because SpaceX now trades publicly, it's excluded from this ranking of private AI companies, even though Grok and xAI's infrastructure remain fully part of the combined business. It's the cleanest recent example of how fast the "highest valued private AI company" list can change — a company can lead the ranking and exit it within four months.

The Rest of the Top 10: Defense, Data, and Applications

Past the two foundation-model giants, the list diversifies fast. Waymo raised $16 billion in February 2026 at a $126 billion valuation, more than double its $45 billion mark from October 2024, with Alphabet remaining the majority investor. Anduril doubled its own valuation to $61 billion in a $5 billion Series H in May 2026, on the back of $2.2 billion in 2025 revenue that itself doubled year-over-year — a rare case of a defense-tech company growing into its multiple with real government contract revenue rather than pure model-scaling capex.

Safe Superintelligence (SSI), Ilya Sutskever's post-scaling research lab, sits at $32 billion despite having no commercially available product — the clearest sign that investors are still pricing pure research talent at a premium. Scale AI is valued around $29 billion, implied by Meta's $14.3 billion investment for a 49% non-voting stake in 2025, though reports suggest a newer tender could value it closer to $25 billion. Mistral, Europe's leading open-weight model lab, was in talks in June 2026 to raise roughly €3 billion ($3.5 billion) at about a €20 billion ($23 billion) valuation — nearly double its September 2025 mark.

Perplexity closed a $200 million round in early June 2026 near a $20 billion valuation, after touching $22.6 billion in a January round — a rare case of a valuation stepping sideways rather than up, reflecting tougher competition in AI search from both Google and ChatGPT. ElevenLabs rounds out the list at $11 billion after tripling its valuation with a $500 million Series D in February 2026, on ARR that grew from $330 million to $500 million in under six months.

What the Top Private AI Company Rankings Tell Investors

Three things stand out in the 2026 data. First, concentration is extreme: Anthropic and OpenAI together are worth $1.82 trillion, more than the combined value of the other eight companies on this list ($437 billion) roughly four times over. Second, the gap between "foundation model lab" and "everything else" is widening, not narrowing — Databricks, the highest-valued non-model-lab AI company, is worth barely a seventh of OpenAI. Third, going public no longer means falling off a list like this one; it means graduating off it, as SpaceX just proved and as Databricks itself may do if it follows through on IPO plans CEO Ali Ghodsi has said won't happen in 2026 given the "terrible year to go public" amid the current wave of AI listings.

For LPs and allocators trying to size AI exposure inside a broader portfolio, the practical takeaway is that "AI exposure" increasingly means exposure to two companies, not a diversified basket.
