Amazon has finished paying out a $50 billion investment in OpenAI, according to the Financial Times, which reported that a regulatory filing disclosed the completed deal. A source told the FT that OpenAI received the final tranche this week, bringing Amazon's stake in the ChatGPT maker to roughly 5 percent.
The closing payment was the largest piece of the deal. Seeking Alpha reported that Amazon completed the investment with an additional $35 billion tranche, and citybiz likewise described the finalized $35 billion tranche as the last step in the $50 billion commitment. PYMNTS.com also reported the completion.
Structuring an investment this way is common for enormous private deals: rather than handing over the full sum at once, the buyer pays in installments, or tranches, spread over time. The final payment is what turns a promise into an actual position on the books — which is why the filing matters more than the original announcement did.
The timing is the other headline. The Economic Times, citing the Financial Times, reported that the investment gives Amazon its roughly 5 percent stake ahead of OpenAI's planned public listing. In other words, Amazon has locked in its ownership before OpenAI's shares are priced by public markets. The Economic Times characterized it as one of the biggest funding deals in the artificial intelligence sector.
None of the sources here detail what Amazon receives beyond equity — no commercial terms, cloud commitments, or governance rights are described in the reporting summarized above.
Why it matters: one of the world's largest companies now owns a slice of the most prominent AI developer just as that developer heads toward the public markets, tightening the already close financial ties between Big Tech and the handful of labs building frontier AI.
