OpenAI Closes $110B Funding Round with Amazon, NVIDIA, and SoftBank at $840B Valuation

A Historic Fundraise

On February 27, 2026, OpenAI closed a $110 billion funding round — the largest private financing in history — valuing the company at $730 billion pre-money and $840 billion including the capital raised.

Investor Breakdown

Amazon: $50 billion ($15B initial + $35B upon conditions being met)

NVIDIA: $30 billion

SoftBank: $30 billion

Microsoft, OpenAI's longtime partner, did not participate in this round but retains its existing equity stake. Additional financial investors are expected to join as the round progresses.

Strategic Implications

Alongside the fundraise, OpenAI will expand its existing $38 billion agreement with AWS by an additional $100 billion over the next eight years — cementing Amazon as a major infrastructure partner while signaling a competitive dynamic with Microsoft Azure.

Context

The announcement comes amid OpenAI's ongoing controversies around its Pentagon contract and competitive pressures from Anthropic, Google DeepMind, and open-source models. The Reddit post scored 233 in r/artificial, with commenters noting that the round dramatically increases OpenAI's capacity to build infrastructure and stay ahead in the AI race — even as questions remain about its organizational structure and mission.
