OpenAI valuation 2026: the numbers that matter
| Metric | Data |
|---|---|
| Latest round size | $122B (largest private round ever) |
| Post-money valuation | $852B |
| Total raised | 15 rounds, $180B cumulative |
| IPO status | Confidential S-1 filed May 22, 2026 |
| Expected IPO timing | Leaning toward 2027 |
| CEO valuation floor | Sam Altman: $1 trillion, no discount |
| Monthly revenue | $2B+ (~$24B annualized) |
| 2025 full-year revenue | $13.1B; not yet profitable |
Valuation gap: $852B private mark sits ~17% ($148B) below Altman's $1T IPO floor — the central pricing battle.
Competitor overtook: Anthropic's latest private valuation hit $965B, passing OpenAI for the first time.
SpaceX retail burn: SpaceX stock fell from $225 to ~$153 within two weeks of its June 12 IPO — down 32%+.
Amazon contingent capital: $35B of Amazon's $50B commitment ties to an IPO or AGI milestone by end-2028.
SoftBank spillover: IPO delay headlines wiped ~$38B off SoftBank's market cap in a single session (-12%+).
OpenAI's funding story tracks its structural evolution: nonprofit in 2015, capped-profit in 2019, Public Benefit Corporation (PBC) in 2025 — each pivot unlocked bigger checks and faster commercialization.
OpenAI funding round 2026: full history and Series G breakdown
Early stage (2015–2019): $130M in grant funding from Musk, Altman, Thiel, Hoffman, and AWS. Microsoft's landmark $1B Series A in July 2019 established Azure as OpenAI's cloud backbone.
ChatGPT era (2023–2024): After ChatGPT launched November 2022, valuation jumped from ~$29B to $157B in under two years — a 440%+ surge.
| Date | Round | Amount | Valuation |
|---|---|---|---|
| Jan 2023 | Series B (Microsoft) | ~$10B | ~$29B |
| Oct 2024 | Series E | $6.6B | $157B |
| Mar 2025 | Series F (SoftBank-led) | $40B | $300B |
Series G timeline (2026):
| Date | Event |
|---|---|
| Feb 27, 2026 | $110B committed at $730B valuation announced |
| Mar 27, 2026 | $4.7B revolving credit line signed (undrawn) |
| Mar 31, 2026 | Close at $122B, $852B valuation |
| Apr 22, 2026 | $75M supplemental round (Robinhood participated) |
| Investor | Commitment | Notes |
|---|---|---|
| Amazon | $50B | $15B cash now; $35B contingent on IPO by end-2028 or AGI |
| Nvidia | $30B | Equity paired with GPU system purchases |
| SoftBank | $30B | Tranched: April, July, October 2026 |
| a16z, D.E. Shaw, MGX, TPG, T. Rowe Price | ~$12B combined | Broad institutional pool |
| Retail via banks | $3B+ | First retail access for OpenAI |
Monthly revenue exceeds $2B with YoY growth running 4×+ the pace Alphabet and Meta saw in their hyper-growth years. OpenAI was added to several ARK Invest ETFs post-close — the most accessible public-market proxy today.
Amazon's $35B contingent tranche evaporates if OpenAI misses end-2028 IPO and AGI triggers. That's a soft but real deadline on Altman's "time for valuation" strategy.
Why OpenAI won't IPO in 2026: Altman's $1 trillion floor and the SpaceX signal
May 22, 2026: Confidential S-1 filed with the SEC.
June 9, 2026: OpenAI confirmed the filing but refused to commit to a timeline.
Original plan: WSJ reported a Q3 2026 (September) debut target.
Latest pivot: NYT June 25 report — leaning toward 2027.
Reason 1 — Sam Altman's $1 trillion floor: Advisers offered a choice: list at a discount in late 2026, or wait for 2027 and chase $1T+. Altman called anything below $1T a "nonstarter." He reportedly holds ~7% from OpenAI's for-profit transition — a trillion-dollar debut moves his personal wealth by billions.
Reason 2 — The SpaceX warning shot:
| Metric | Data |
|---|---|
| IPO date | June 12, 2026 |
| Capital raised | $85B+ (largest IPO ever) |
| Peak valuation | $2.77T; Musk briefly world's first trillionaire |
| Peak → recent | $225 → ~$153 (down 32%+ by June 26) |
Bankers told OpenAI: retail investors burned on SpaceX may not line up for the next mega-AI listing at premium private marks. Private vs. public valuation gaps are real.
Reason 3 — Internal financial readiness: CFO Sarah Friar (ex-Nextdoor CEO, joined 2024) advocates slower IPO prep and stronger reporting infrastructure. Several employees reportedly felt the company wasn't ready for quarterly earnings scrutiny while still burning cash on infrastructure.
| Platform | Forecast |
|---|---|
| Kalshi | 59% — IPO announced by March 1, 2027 |
| Kalshi | 73% — announced by June 2027 |
| Polymarket | ~30–40% odds of 2026 listing |
How to invest in OpenAI before the IPO: six-step runbook
ARK Invest ETFs: OpenAI entered multiple ARK funds after the March 2026 close — lowest-friction retail proxy.
Secondary markets: Forge Global and EquityZen occasionally list employee/early-investor shares. Expect high minimums and liquidity limits.
SoftBank (9984.T): ~13% OpenAI stake. Highly correlated — IPO delay erased ~$38B in one Tokyo session.
Microsoft (MSFT): Partnership plus equity since the 2019 $1B bet; total stake above $13B.

OpenAI vs Anthropic vs SpaceX: who leads the 2026 IPO race?
| Company | Latest valuation | IPO status | Monthly revenue |
|---|---|---|---|
| OpenAI | $852B | Confidential S-1; leaning 2027 | $2B+ |
| Anthropic | $965B | S-1 filed June 1; targeting late 2026 | Undisclosed |
| SpaceX | ~$2.77T peak | Public since June 12; pulling back | — |
If Anthropic lists first, its opening print becomes OpenAI's pricing anchor. SoftBank (~13%) wants a fast exit; Amazon's contingent tranche incentivizes a timely debut. Watch: Anthropic IPO progress, OpenAI monthly revenue crossing $3B, Amazon's 2028 deadline, macro rates, and AGI milestone claims affecting contingent capital.
$122B single-round record: Largest private financing in Silicon Valley history.
17% premium to $1T: $852B → $1T requires revenue acceleration or a friendlier market — or both.
SoftBank -12% single day: Clearest market signal that private-public valuation gaps remain unresolved.

OpenAI's IPO arc coincides with GPT-5.6 and Agent adoption — but laptop sleep cycles and Linux VPS hosts without Xcode or Metal burn API savings on downtime.

Unlikely. NYT reported a 2027 lean on June 25. Kalshi puts 2026 listing odds at ~30–40%. Cloud Mac pricing at our pricing page.
$852 billion post-money after the March 31, 2026 Series G close. Fifteen rounds, $180 billion total raised. Altman won't IPO below $1 trillion.
Altman's $1T floor (17% above $852B private mark), SpaceX's 32% post-IPO drop scaring retail, and CFO Sarah Friar pushing for public-grade financial reporting first.
ARK ETFs, Forge/EquityZen secondaries, SoftBank 9984.T (~13%), Microsoft MSFT. Details in our help center.
$35B of Amazon's $50B pledge requires an IPO by end-2028 or hitting an internal AGI definition — otherwise it may not fund. Soft pressure on Altman's timeline.
Anthropic at $965B now tops OpenAI's $852B. Anthropic filed S-1 June 1 targeting late 2026 — if it lists first, it sets OpenAI's market anchor. Read our Anthropic IPO guide.
