OpenAI's $852B Valuation in 2026: How the World's Most Valuable AI Company Is Priced

OpenAI is valued at $852 billion after closing a $122 billion funding round on March 31, 2026 — up 70% from the $500 billion mark it set just five months earlier. That's the short answer. The longer answer is that the price is being set almost entirely by compute access and revenue growth, not current profitability.

OpenAI's valuation has roughly tripled in under two years: from $157 billion in an October 2024 round to $300 billion in March 2025, $500 billion via an employee tender in October 2025, and $852 billion after the March 2026 round closed. Along the way it locked in over $500 billion in disclosed cloud and compute commitments through its Stargate initiative. Here's what the $852 billion actually reflects, what the business generates today, and how it stacks up against Anthropic and xAI.

What is OpenAI's valuation in 2026?

OpenAI's valuation in 2026 is $852 billion, set by a $122 billion funding round that closed on March 31, 2026 — larger than the $110 billion the company had first announced in February. The round was co-led by SoftBank alongside Andreessen Horowitz, D.E. Shaw Ventures, MGX, TPG, and T. Rowe Price-advised accounts, with strategic partners Amazon ($50B), Nvidia ($30B), SoftBank ($30B), and Microsoft also participating. That's up 70% from the $500 billion valuation set by a $6.6 billion employee tender offer in October 2025, itself the largest private-company secondary sale on record.

Who is actually paying for the $852 billion valuation

The March 2026 round is notable for who wrote checks: Amazon put in $50 billion, Nvidia and SoftBank each contributed $30 billion, and Microsoft participated as a strategic partner alongside financial investors like Andreessen Horowitz, D.E. Shaw Ventures, MGX, TPG, and T. Rowe Price-advised accounts. OpenAI also opened up $3 billion of the round to individual investors through bank channels for the first time, a signal of how large and normalized these AI mega-rounds have become. For more on how these valuations compare across the AI landscape, see our AI valuations dashboard.

Based on the last fully disclosed cap table snapshot (from around the $500 billion tender), Microsoft holds roughly 27% of OpenAI and the nonprofit OpenAI Foundation holds about 26%, with the rest split across employees, SoftBank, Thrive Capital, and other backers. Those percentages are diluted further by the 2025 and 2026 rounds, though OpenAI has not published a clean, updated ownership table since the structure shifted with its for-profit conversion.

Is OpenAI's 2026 valuation justified by revenue?

Only partly. OpenAI's annualized revenue run rate reached roughly $25 billion by mid-2026, up from $21.4 billion at the end of 2025 and just $3.7 billion for full-year 2024 — a genuinely fast climb. That $25 billion breaks down into roughly $17 billion from ChatGPT subscriptions, $6.5 billion from API consumption, and $1.5 billion from Sora video generation and licensing. But profitability remains distant: HSBC estimates OpenAI will lose about $14 billion in 2026 alone, with cumulative losses near $44 billion between 2023 and 2028, burn rising toward $27 billion in 2026 and $63 billion in 2027, and no projected cash-flow breakeven until 2030.

At $852 billion against $25 billion in annualized revenue, OpenAI trades at roughly a 34x revenue multiple — well above the 15-20x typical of high-growth enterprise SaaS, and above the roughly 20x multiple implied by Anthropic's higher revenue base. The bet isn't on today's subscription and API revenue alone; it's on ChatGPT's distribution advantage, enterprise API adoption accelerating further, and OpenAI's ability to keep securing the compute it needs through deals like Stargate.

OpenAI vs Anthropic vs xAI: the 2026 valuation gap

Figures from CNBC's May 2026 reporting on Anthropic's Series H, Bloomberg and Forbes coverage of OpenAI's March 2026 round, and reporting on xAI's Series E and SpaceX merger. Multiples are approximate, calculated on the latest disclosed valuation against the most recent reported annualized revenue figure.

Anthropic technically overtook OpenAI on headline valuation in May 2026, closing its Series H at $965 billion versus OpenAI's $852 billion. But Anthropic's revenue base is also nearly double OpenAI's — roughly $47 billion in annualized revenue by mid-May 2026 against OpenAI's $25 billion — meaning Anthropic's implied multiple is actually lower, around 21x versus OpenAI's 34x. xAI, by contrast, carries the highest multiple of the three on its standalone $230 billion valuation, reflecting how much smaller its core AI revenue base still is.

Stargate: the $500 billion bet behind OpenAI's valuation

Much of OpenAI's valuation growth over the past 18 months tracks its compute commitments, not just its subscription business. Stargate, the joint venture with Oracle and SoftBank announced in January 2025, is now a roughly $500 billion plan over four years to build out 10 gigawatts of AI data center capacity in the US. Five additional Stargate sites have since been announced, bringing the initiative to nearly 7 gigawatts of capacity and over $400 billion in disclosed investment across roughly three years. Layered on top of that, OpenAI has committed to $250 billion of Azure cloud services from Microsoft and a separate Oracle cloud deal reportedly worth about $300 billion over roughly five years starting in 2027.

That's the real asset being priced at $852 billion: not just ChatGPT's current 800 million-plus weekly users, but a claim on hundreds of billions of dollars in locked-in compute capacity that competitors would need years to replicate. It's also the clearest explanation for why investors like Nvidia and Microsoft — both of which sell OpenAI the infrastructure it needs — are simultaneously funding the equity round.

How OpenAI's business mix has shifted since 2024

The composition of OpenAI's revenue has changed meaningfully in the 18 months leading up to the $852 billion valuation. In 2024, the business was overwhelmingly ChatGPT Plus and Team subscriptions; by mid-2026, API consumption from enterprise customers has grown into a $6.5 billion annualized slice of the roughly $25 billion total, reflecting a broader shift toward companies building products on top of OpenAI's models rather than just employees using ChatGPT directly. Sora video generation and licensing revenue, effectively nonexistent before Sora's 2025 relaunch, now contributes an estimated $1.5 billion annualized — small next to the ChatGPT and API lines but the fastest-growing of the three.

That diversification matters for how investors underwrite the $852 billion price tag. A company whose revenue depends entirely on consumer subscription renewals is priced differently than one with three growing, structurally distinct revenue lines — even if the total dollar figure is similar. It's also why OpenAI's investor base has shifted from primarily financial backers (Thrive Capital, SoftBank, Sequoia in earlier rounds) toward strategic infrastructure partners like Amazon, Nvidia, and Microsoft, all of whom benefit directly from OpenAI's compute spending regardless of how the equity performs. Compare that structure to how growth-stage valuations get set more broadly on our SaaS valuations dashboard, where multiples are typically anchored to net revenue retention and gross margin rather than compute commitments.

Could OpenAI's valuation still fall in 2026-2027?

Yes, and the risk is concentrated in three places. First, the 34x revenue multiple depends on ARR growth staying fast enough to outrun the losses — any visible deceleration from the roughly 17% run-rate growth OpenAI posted between the end of 2025 and February 2026 would be read as evidence the multiple is unsupportable. Second, HSBC's projection of $63 billion in 2027 burn assumes continued access to capital at a pace few private companies have ever sustained; a funding-market pullback would force hard choices between compute spending and cash preservation. Third, an eventual IPO would subject the same numbers private investors have largely waved through — a 34x revenue multiple, a 2030 breakeven target, and over $500 billion in compute obligations — to public-market scrutiny that could compress the multiple significantly.

None of that means $852 billion is wrong today. OpenAI has consistently raised at valuations that looked aggressive on then-current revenue and grown into them within 12-18 months, as the climb from $157 billion in October 2024 to $852 billion in March 2026 shows. But it does mean the multiple leaves less room for error than Anthropic's lower, revenue-backed multiple, even though OpenAI's absolute valuation briefly led the market before Anthropic's May 2026 round overtook it.

What OpenAI's $852B valuation means for investors

For anyone underwriting exposure to OpenAI — through secondaries, an SPV, or eventual public shares — the honest framing is that you're paying roughly 34 times current revenue for a company that HSBC does not expect to be cash-flow positive until 2030. That only makes sense if ChatGPT and the API business keep compounding at something close to their 2025-2026 pace, and if the $500 billion- plus in Stargate and cloud commitments translates into durable competitive advantage rather than just higher depreciation.

The more durable signal is the structural one: strategic investors who sell OpenAI its compute — Nvidia, Microsoft, and increasingly Amazon — are also funding its equity round, tying supplier and shareholder incentives together in a way that's unusual even by AI industry standards. That alignment, more than the headline $852 billion number, is the clearest read on why the market has kept funding OpenAI's losses at an accelerating valuation heading into 2027.
