OpenAI closes record $110 billion funding round at $730 billion pre-money valuation, with Amazon, Nvidia, and SoftBank as anchor investors and round remaining open for additional backers
OpenAI closes record $110 billion funding round at $730 billion pre-money valuation, with Amazon, Nvidia, and SoftBank as anchor investors and round remaining open for additional backers
In October 2024, OpenAI raised $6.6 billion at a $157 billion valuation. Seventeen months later, on February 27, 2026, the maker of ChatGPT closed a record $110 billion funding round at a $730 billion pre-money valuation ($840 billion post-money)—the largest private capital raise in history. Amazon led with a $50 billion commitment ($15 billion upfront, $35 billion contingent on OpenAI achieving AGI or completing an IPO by year-end), while Nvidia and SoftBank each committed $30 billion. The round remains open for additional investors. The deal includes expanded infrastructure partnerships: Amazon will provide $100 billion in additional AWS compute services over eight years (on top of the existing $38 billion commitment), while Nvidia will supply 3 gigawatts of dedicated inference capacity and 2 gigawatts of training capacity using its Vera Rubin systems.

The final deal represents a dramatic restructuring of OpenAI's capital relationships. Nvidia's $30 billion equity stake replaces the stalled $100 billion milestone-linked infrastructure deal announced in September 2025, decoupling the chipmaker's financial bet from hardware deployment targets. Amazon's investment ties $35 billion to specific milestones—AGI achievement or IPO completion—creating performance incentives that reflect investor skepticism about OpenAI's path to profitability. OpenAI projects cumulative losses through 2028 and spent roughly $1.69 for every dollar of revenue in 2025, making the valuation dependent on sustained AI demand growth and successful commercialization of frontier models.
OpenAI officially closes $110 billion funding round at $730 billion pre-money valuation ($840 billion post-money). Amazon commits $50B ($15B upfront, $35B contingent on AGI or IPO by year-end), Nvidia and SoftBank each commit $30B. Round remains open for additional investors.

Scenarios
1
Round Closes Above $100B, OpenAI Files for IPO
Discussed by: TechCrunch, Caproasia, and multiple Wall Street analysts tracking OpenAI's trajectory
All three anchor investors—Nvidia, SoftBank, and Amazon—finalize their commitments, bringing the round above $100 billion. The capital injection funds OpenAI's $600 billion compute spending plan through 2030 and positions the company for an initial public offering in late 2026 or 2027 at a valuation approaching $1 trillion. OpenAI's chief financial officer Sarah Friar has told associates the company is targeting a 2027 listing, and the for-profit restructuring completed in October 2025 removed the final structural barrier.
2
Round Shrinks as One or More Investors Pull Back
Discussed by: Business Standard, The Information, and analysts who noted the $100B Nvidia deal's collapse as a precedent
One or more anchor investors reduce their commitments or drop out, shrinking the round significantly. Amazon's talks—which involve OpenAI adopting Amazon's custom Trainium chips—face the same structural complications that stalled the original Nvidia deal. OpenAI still raises tens of billions but at a lower valuation, and the IPO timeline slips as the company's $9 billion annual losses continue to require fresh capital.
3
Circular Funding Draws Regulatory or Investor Scrutiny
Discussed by: TechCrunch, which flagged the 'circular deals' dynamic, and financial analysts questioning the structure
The intertwined nature of these deals—Amazon invests in OpenAI, OpenAI spends $38 billion on Amazon's cloud; Nvidia takes equity, OpenAI buys Nvidia chips—attracts scrutiny from regulators or skeptical institutional investors. Questions about whether the investments represent genuine capital allocation or subsidized customer acquisition could complicate the IPO process or trigger antitrust review, particularly given the Federal Trade Commission's existing interest in AI industry concentration.
4
AI Spending Boom Cools, OpenAI's Losses Force a Reckoning
Discussed by: Medium's Will Lockett, Naked Capitalism, and analysts projecting $143 billion in cumulative negative free cash flow through 2029
If demand for AI products plateaus or a competing open-source model erodes OpenAI's pricing power, the company's path to profitability—which it projects for 2029 or 2030—becomes less credible. Investors who poured in at a $730 billion-plus valuation face significant markdowns. The parallel to SoftBank's Vision Fund era, where massive capital commitments preceded a wave of down rounds and writedowns, becomes harder to dismiss.
Historical Context
SoftBank Vision Fund and WeWork (2017-2019)
2017-2019
What Happened
SoftBank invested approximately $16 billion in WeWork through its Vision Fund and other vehicles, pushing the coworking company's valuation to $47 billion. WeWork's September 2019 initial public offering filing revealed unsustainable losses, and the IPO collapsed. Within weeks, WeWork's implied valuation fell 83% to $8 billion, and SoftBank assembled a $9.5 billion rescue package.
Outcome
Short Term
WeWork abandoned its IPO, ousted its founder-CEO Adam Neumann, and accepted a SoftBank bailout that gave the Japanese conglomerate effective control of the company.
Long Term
The episode became shorthand for the dangers of massive private-market overvaluation. SoftBank's Vision Fund I ultimately recovered much of its losses through other bets, but investor confidence in mega-round private market valuations took years to rebuild.
Why It's Relevant Today
SoftBank is again one of the largest investors in a money-losing private company seeking a valuation in the hundreds of billions. The key difference: OpenAI's revenue is growing rapidly (from $3.7 billion in 2024 to roughly $13 billion in 2025), whereas WeWork never had a credible path to profitability. The key similarity: the sheer scale of capital at risk if growth assumptions prove wrong.
Microsoft's $150 Million Investment in Apple (1997)
August 1997
What Happened
Microsoft invested $150 million in Apple at a time when the computer maker was near bankruptcy. The investment came with agreements for Microsoft to continue developing Office for the Mac and to settle patent disputes. Steve Jobs announced the deal at Macworld to a chorus of boos from Apple loyalists who saw it as capitulation to a rival.
Outcome
Short Term
The investment stabilized Apple financially and signaled market confidence, helping reverse a multiyear stock decline.
Long Term
Apple went on to become the world's most valuable company. Microsoft sold its shares by 2003, missing out on hundreds of billions in gains. The deal demonstrated that a strategic investment by a dominant platform company in a key partner can reshape an entire industry.
Why It's Relevant Today
Nvidia's equity investment in OpenAI mirrors the structural logic: a dominant supplier (Microsoft made the software, Nvidia makes the chips) takes a financial stake in a company that is simultaneously its largest customer and potential competitor. The question is whether Nvidia is buying into a transformative partner or subsidizing a customer whose long-term hardware choices remain uncertain.
AOL-Time Warner Merger (2000)
January 2000 - January 2001
What Happened
At the peak of the dot-com bubble, America Online acquired Time Warner for $164 billion in what was then the largest corporate merger in history. AOL's stock price had inflated its market value to over $200 billion on the promise that internet connectivity would transform media. The deal closed in January 2001.
Outcome
Short Term
The combined company wrote down nearly $99 billion in value within two years as AOL's dial-up business collapsed amid the rise of broadband.
Long Term
The merger became the defining cautionary tale of using inflated valuations to acquire real assets. Time Warner eventually spun off AOL in 2009 at a fraction of the original price.
Why It's Relevant Today
The parallel is not in the deal structure but in the valuation question. OpenAI's $730 billion pre-money valuation is roughly 56 times its 2025 revenue, at a time when the company projects losses through 2028. If artificial intelligence revenue growth follows the trajectory its backers expect, the valuation looks prescient. If growth slows, it risks looking like another case of capital chasing hype at historic scale.
