OpenAI’s latest funding round valued the ChatGPT maker at $840bn as Big Tech piled into the $110bn blockbuster round, signaling the AI investment race is alive and well despite recent fears of a valuation bubble.
The funding round, one of the largest private capital raises on record, includes a $30bn investment from SoftBank, $30bn from Nvidia, and $50bn from Amazon. It comes ahead of the AI startup’s expected mega-IPO this year, and Wall Street expects more funding rounds before the debut.
More investors are expected to join the round as it progresses, OpenAI said in a statement on Friday.
Funding boost as competition heats up
The infusion will help OpenAI secure advanced AI chips and the computing capacity it needs to maintain its lead position in the AI industry, especially as competition heats up from Anthropic and Alphabet’s Google.

It also exacerbates Wall Street concerns about “circular” financing agreements, where firms invest in and sign supply deals with each other, inflating demand and revenue.
After years of outsized gains, tech stocks have suffered sharp declines in 2026 as investors question whether AI investments will generate sufficient returns to justify lofty valuations.
Nvidia was punished by shareholders this week after the chipmaker said it would pour money into the AI ecosystem, instead of returning cash to shareholders. Nvidia’s investment in OpenAI gives the chip company a financial stake in one of its largest customers, tightening their already intertwined relationship.
OpenAI said on Friday it would use Nvidia’s latest Rubin systems, representing five gigawatts of computing capacity, enough energy to power millions of US households.
It was not immediately clear whether Nvidia’s $30bn investment replaced its earlier commitment announced in September under which Nvidia was set to invest up to $100bn in the startup.
OpenAI and Nvidia did not immediately respond to Reuters’ requests for clarification.
With the latest injection, SoftBank’s investment in OpenAI is set to be $64
6bn, representing an ownership interest of about 13 per cent, the Japanese conglomerate said.
Amazon partnership
The new investment is crucial for OpenAI.
The launch of Google’s Gemini 3 in November has given the Alphabet-owned company a stronger footing, while Anthropic has cemented its lead in the enterprise AI market with its specialized coding tool.
OpenAI, which is yet to turn a profit, is targeting roughly $600bn in total compute spend through 2030, a source told Reuters last week.
Along with the $50bn investment, OpenAI and Amazon have also struck a deal in which OpenAI will utilize two gigawatts of computing capacity powered by Amazon’s in-house Trainium AI chips.
The companies are also expanding their $38bn cloud deal signed last year, with OpenAI saying it would spend an additional $100bn on Amazon Web Services over the next eight years. As well, OpenAI will work with Amazon to develop customized models for the e-commerce company’s engineering teams.
Amazon will start with an initial $15bn investment, followed by another $35 billion in the coming months when certain conditions are met, the companies said.
AWS will be the exclusive third-party cloud provider for OpenAI Frontier, the ChatGPT maker’s enterprise platform for building and running AI agents.
The partnership does not change OpenAI’s relationship with Microsoft, with Microsoft Azure still the exclusive cloud provider for OpenAI’s APIs that provide access to OpenAI’s models, the companies said.
ChatGPT serves more than 900 million weekly active users, OpenAI said, adding that it has surpassed 50 million consumer subscribers. January and February are on track to become the largest months for new subscriber additions, it said.
