TL;DR: OpenAI announced a $110 billion funding round on February 27, 2026, shattering every record for private company financing. Amazon committed $50 billion, Nvidia invested $30 billion, and SoftBank added another $30 billion. The pre-money valuation sits at $730 billion, making OpenAI the most valuable private company in history by a wide margin. The round remains open, with sovereign wealth funds and additional investors expected to pile in.**
On February 27, 2026, OpenAI confirmed the largest private financing in history. Three investors split $110 billion across a single round against a $730 billion pre-money valuation. Post-money, OpenAI is now valued at approximately $840 billion.
Here is how the capital stacks up:
| Investor | Amount | Structure | Key terms |
|---|---|---|---|
| Amazon | $50B | $15B immediate + $35B conditional | Series C preferred equity |
| Nvidia | $30B | New equity investment | First direct equity stake |
| SoftBank | $30B | New equity tranche | Total OpenAI exposure now ~$64.6B |
The round remains open. OpenAI has spent the past two weeks meeting with sovereign wealth funds and other financial investors about adding another $10 billion, with final indications due shortly.
For context, this single round is larger than the GDP of over 130 countries. It dwarfs the previous record for private tech financing. OpenAI's own October 2024 round, which raised $6.6 billion at a $157 billion valuation, looked massive at the time. That number now looks like a rounding error.
"We're super excited about this deal. AI is going to happen everywhere. It's transforming the whole economy, and the world needs a lot of collective computing power to meet demand." -- @sama
Sam Altman told CNBC on Friday morning that the deal reflects a new phase for the company. "We are entering a new phase where frontier AI moves from research into daily use at global scale," Altman said. "Leadership will be defined by who can scale infrastructure fast enough to meet demand, and turn that capacity into products people rely on."
Amazon's investment is the largest single commitment in the round. The $50 billion breaks into two parts. The first $15 billion is an immediate Series C preferred equity investment. The remaining $35 billion comes through a separate, conditional equity commitment via an Amazon subsidiary, guaranteed by the parent company. That second tranche activates "when certain conditions are met," though neither company has specified exactly what those conditions are.
But the equity is only half the story. The real strategic prize is the expanded cloud agreement.
OpenAI and AWS already had a $38 billion multi-year infrastructure deal. This announcement expands that agreement by an additional $100 billion over eight years, bringing the total cloud commitment to approximately $138 billion. Under this expanded deal, OpenAI will consume roughly 2 gigawatts of Amazon's custom Trainium silicon, spanning both the current Trainium 3 generation and the upcoming Trainium 4, which is expected to ship next year.
AWS also becomes the "exclusive third-party cloud distribution provider" for OpenAI Frontier, the company's enterprise AI platform for building and managing teams of AI agents. That means AWS customers will get privileged access to OpenAI's most advanced enterprise tools before anyone else outside of Microsoft's Azure.
For Amazon, this is a multi-layered play. They get equity upside in the most valuable AI company. They lock in a massive, long-term cloud customer. And they get distribution rights for enterprise AI products that competitors would love to offer first.
"Amazon can deliver so much to us in terms of new demand and opportunities in the market," Altman said in his CNBC interview.
There is also a customer-facing dimension. Amazon announced a multi-year strategic partnership to develop customized models that will power Amazon's own consumer applications. That likely means OpenAI models integrated into Alexa, Amazon shopping, and AWS developer tools.
Nvidia's participation is notable because this is the company's first direct equity investment in OpenAI. Nvidia has been OpenAI's primary hardware supplier for years. The two companies have been deeply intertwined since the early days of GPT research. But until now, Nvidia had not taken a direct financial stake.
The $30 billion investment comes alongside an expanded infrastructure commitment. OpenAI will use 3 gigawatts of dedicated inference capacity and 2 gigawatts of training capacity on Nvidia's next-generation Vera Rubin systems. The first gigawatt of this infrastructure is targeted for deployment in the second half of 2026.
Vera Rubin is Nvidia's successor to the current Blackwell architecture. It introduces the Vera CPU alongside next-generation NVLink interconnect technology, a new Transformer Engine, and updated confidential computing capabilities. Nvidia CEO Jensen Huang has described Vera Rubin as delivering up to a 10x reduction in inference token cost compared to Blackwell, though independent benchmarks are not yet available.
For Nvidia, the investment makes strategic sense on multiple levels. OpenAI is one of the largest GPU buyers on the planet. Locking in a multi-year hardware commitment while also taking an equity position creates alignment that goes beyond a typical vendor-customer relationship. If OpenAI succeeds in becoming the dominant AI platform company, Nvidia profits from both the chip sales and the equity appreciation.
The timing is also significant. Nvidia reported Q4 FY26 earnings just two days earlier, on February 25, posting $68.1 billion in quarterly revenue with data center sales of $62.3 billion. The company is sitting on enormous cash flows and has been looking for strategic uses of capital beyond buybacks. A $30 billion bet on its most important customer fits that playbook.
SoftBank's $30 billion in this round brings its total OpenAI exposure to approximately $64.6 billion, representing a roughly 13% stake in the company. That makes Masayoshi Son's firm the single largest outside investor in OpenAI.
The path to this position has been aggressive. In late 2025, SoftBank completed a $41 billion investment that gave it approximately an 11% stake. To free up capital for the follow-on, SoftBank controversially exited its entire $5.8 billion position in Nvidia. Selling the premier AI hardware company to double down on the premier AI software company was a bold choice that generated significant debate in the investment community.
Son has been OpenAI's most vocal corporate champion. SoftBank swung to profit in its most recent quarter largely on the back of valuation gains from its OpenAI position. The company's share price has surged as Son has articulated what he calls the "Izanagi" AI strategy, named after a figure in Japanese mythology, positioning SoftBank as a central financing node for the global AI build-out.

The risk for SoftBank is concentration. At $64.6 billion, OpenAI represents a substantial portion of SoftBank's total portfolio value. If the AI market hits a downturn or OpenAI stumbles operationally, SoftBank's balance sheet takes a direct hit. Son has shown through his career that he is comfortable with concentrated bets. The WeWork experience showed what happens when those bets go wrong.
The most conspicuous absence from the announcement is Microsoft. The company that has been OpenAI's primary partner since 2019, investing $13.8 billion across multiple rounds, did not participate in this round.
OpenAI and Microsoft moved quickly to contain the narrative. A joint statement from both companies said the partnership "remains strong and central" and that "nothing about this announcement in any way changes the terms" of their existing relationship.
Microsoft still holds an option to participate in the funding round, according to sources familiar with the matter. Whether they exercise that option remains to be seen.
The backdrop here is important. In October 2025, OpenAI completed its restructuring from a nonprofit to a for-profit public benefit corporation. The OpenAI Foundation now holds approximately 26% of the new entity. Microsoft holds approximately 27%. With SoftBank at roughly 13% and now Amazon and Nvidia holding significant stakes, the ownership table is becoming crowded.
Microsoft earned $7.6 billion from OpenAI last quarter, according to its January 2026 earnings report. The company's Azure cloud platform remains OpenAI's primary infrastructure provider. But the Amazon deal introduces a second major cloud relationship, and the AWS exclusive distribution rights for OpenAI Frontier create a competitive dynamic that did not exist before.
For Microsoft, the calculus is complicated. Adding more capital to a round where Amazon is the lead investor does not obviously serve Microsoft's strategic interests. At the same time, not participating means dilution. The option to invest later gives Microsoft flexibility to observe how the Amazon partnership develops before committing additional capital.
One of the most technically significant announcements bundled into the funding news was the "Stateful Runtime Environment" that OpenAI and AWS will co-develop.
This is not just marketing language. A stateful runtime environment allows AI agents to maintain context across sessions, remember prior work, operate across multiple software tools and data sources, and access persistent compute. Think of it as the difference between an AI that starts fresh every time you open a conversation and one that picks up where it left off, with full awareness of everything it has done before.
The Stateful Runtime Environment will be powered by OpenAI models and offered through Amazon Bedrock. It will integrate with Amazon Bedrock AgentCore and AWS infrastructure services so that customers' AI applications run cohesively with the rest of their infrastructure.
This matters because the current generation of AI agents is largely stateless. You prompt them, they respond, and the conversation ends. The next generation of enterprise AI needs to be able to manage ongoing projects, coordinate across systems, and maintain memory over weeks or months of continuous operation. The stateful runtime is the infrastructure layer that makes that possible.
The product is expected to launch "in the next few months." When it does, it will be one of the first production-grade infrastructure offerings specifically designed for long-running AI agent workloads.
The $110 billion raise only makes sense if you believe OpenAI can generate revenue at a scale that justifies its $840 billion valuation. So where does the company actually stand financially?
OpenAI hit a $12.7 billion annual revenue run rate earlier this year, according to multiple reports. That number has been growing rapidly. In October 2024, the company was at roughly $3.4 billion ARR. Growing from $3.4 billion to $12.7 billion in roughly 16 months is extraordinary, though the company is still not profitable by conventional measures.
The burn rate is also significant. Training frontier AI models costs hundreds of millions of dollars per run. Operating inference infrastructure at global scale requires massive ongoing spending. OpenAI has consistently spent more than it earns, which is precisely why it needs to raise capital at this scale.
Altman addressed the spending concerns directly on CNBC. "I get where the concern comes from," he said. "This only makes sense if new revenue flows into the whole AI ecosystem."
The implied bet is that AI infrastructure spending today will generate outsized returns as AI agents become integrated into every major industry. If AI agents eventually handle a meaningful percentage of knowledge work, the market opportunity dwarfs the current investment. If adoption is slower than expected, or if competitors erode OpenAI's position, $110 billion in capital consumption becomes a very expensive lesson.
| Metric | Oct 2024 | Feb 2026 | Change |
|---|---|---|---|
| Valuation | $157B | $840B | ↑ 435% |

This round resets expectations for the entire AI sector. When a single company can raise $110 billion in one round, it sends a signal about how much capital the market believes AI will require and generate.
For competitors, the pressure just increased significantly. Anthropic, which has raised approximately $18 billion to date, will likely need to raise again to maintain pace. Google has deep pockets through Alphabet but faces different constraints as a public company. Meta is building AI infrastructure with internal capital but is not competing directly in the enterprise AI platform market.
For startups, the dynamics are mixed. On one hand, the amount of capital flowing into AI infrastructure creates opportunities for specialized companies that build on top of foundation models. On the other hand, when the platform companies have this much capital, they can expand into adjacent markets quickly, making it harder for startups to build defensible positions.
The cloud infrastructure market is also being reshaped. The Amazon-OpenAI partnership creates a new competitive axis against Microsoft Azure's existing OpenAI integration. Google Cloud has its own Gemini-based offerings. The three-way battle for enterprise AI platform dominance now has a new configuration.

For enterprise buyers, the immediate implication is that OpenAI's products will become more deeply integrated with AWS. If your organization runs on Amazon's cloud, accessing OpenAI's enterprise tools just got significantly easier. If you are a Microsoft shop, the existing Azure OpenAI Service remains unchanged, but the competitive dynamics have shifted.
The broader question is whether this level of spending is sustainable. The AI industry is currently in a capital deployment phase where the biggest players are betting that infrastructure built today will generate returns over the next decade. That bet has historical precedent in cloud computing, where Amazon, Microsoft, and Google spent tens of billions building data centers before the economics fully materialized. But the scale here is unprecedented, and the technology is less mature.
OpenAI has signaled that the round is not yet closed. The company has been meeting with sovereign wealth funds and institutional investors about adding approximately $10 billion more. If that happens, the total raise could exceed $120 billion.
The round's structure also leaves room for Microsoft to participate. Whether they do will be one of the most watched corporate finance decisions of 2026. A Microsoft investment would signal confidence that the partnership can coexist with the Amazon relationship. A pass would suggest Microsoft is reevaluating its exposure.
Looking ahead, the capital will fund continued model development, infrastructure expansion, and product launches. OpenAI has been expanding its product surface rapidly, from ChatGPT to enterprise APIs to the Frontier agent platform to the new Stateful Runtime Environment. Each of these products requires significant ongoing investment.
The company is also likely positioning for an eventual IPO. At an $840 billion valuation, OpenAI would be one of the largest IPOs in history whenever it decides to go public. The for-profit restructuring completed in October 2025 removed a structural barrier to a public offering, and the current round gives the company enough capital to choose its timing rather than being forced to the public markets.
OpenAI raised $110 billion in a single funding round announced on February 27, 2026. This is the largest private company financing in history. Amazon invested $50 billion, Nvidia invested $30 billion, and SoftBank invested $30 billion. The round values OpenAI at $730 billion pre-money and approximately $840 billion post-money.
Amazon is investing $50 billion in total. The first $15 billion is an immediate Series C preferred equity investment. The remaining $35 billion is a conditional equity commitment through an Amazon subsidiary, guaranteed by the parent company, to be deployed "when certain conditions are met." Separately, Amazon and OpenAI expanded their AWS cloud agreement by $100 billion over eight years.
Nvidia invested $30 billion for a new equity stake in OpenAI. This is Nvidia's first direct equity investment in the company, despite being OpenAI's primary GPU supplier for years. The deal includes an expanded infrastructure commitment: OpenAI will use 3 gigawatts of dedicated inference capacity and 2 gigawatts of training capacity on Nvidia's next-generation Vera Rubin systems.
SoftBank's $30 billion commitment in this round brings its total OpenAI investment to approximately $64.6 billion, giving it a roughly 13% stake. SoftBank had previously invested approximately $41 billion across earlier rounds. To fund its OpenAI position, SoftBank sold its entire $5.8 billion stake in Nvidia.
Microsoft did not participate in the initial announcement. However, the company retains an option to invest in the round. OpenAI and Microsoft issued a joint statement saying the partnership "remains strong and central" and that "nothing about this announcement in any way changes the terms" of their existing partnership. Microsoft currently holds approximately 27% of OpenAI.
The Stateful Runtime Environment is a new infrastructure product co-developed by OpenAI and AWS. It allows AI agents to maintain context across sessions, remember prior work, operate across multiple software tools, and access persistent compute. It will be powered by OpenAI models and offered through Amazon Bedrock, with a launch expected in the next few months.
OpenAI's annual revenue run rate is approximately $12.7 billion as of early 2026. That is up from roughly $3.4 billion at the time of the company's October 2024 funding round. The company is growing rapidly but is not yet profitable, as training and inference costs for frontier AI models consume significant capital.
OpenAI raised $6.6 billion in October 2024 at a $157 billion valuation. The current $110 billion round at a $730 billion pre-money valuation represents a roughly 4.7x increase in valuation in approximately 16 months. The round size itself is nearly 17 times larger than the previous one.
OpenAI's pre-money valuation is $730 billion. Including the $110 billion in new capital, the post-money valuation is approximately $840 billion. This makes OpenAI the most valuable private company in history, and its valuation would place it among the top 10 most valuable companies globally if it were publicly traded.
Yes. OpenAI has confirmed the round remains open. The company has been meeting with sovereign wealth funds and institutional investors about adding approximately $10 billion more. Microsoft also retains an option to participate. If additional investors join, the total raise could exceed $120 billion.
