[Amazon Completes $50 Billion Investment in OpenAI Ahead of Schedule, Holds Approximately 5% Stake] Amazon has completed its follow-up $35 billion investment in OpenAI ahead of schedule, bringing the total investment to $50 billion (approximately $33.8245 billion), with a current stake of about 5%. Despite OpenAI not meeting the two conditions of going public and achieving a technological breakthrough, Amazon still chose to fulfill its commitment early, making the final payment this week. Renegotiation of the contract between OpenAI and Microsoft in April was a key prerequisite for Amazon's agreement to invest the full amount.
