GeekWire·high signal

Amazon closed its $50B investment in OpenAI ($15B initial + $35B conditional), making it one of the largest single investments in tech history. The deal includes expanding an existing $38B cloud agreement by $100B over eight years with a 2GW Trainium chip commitment. Combined with NVIDIA and SoftBank funding, OpenAI reached an $840B valuation — directly triggering the Microsoft deal restructuring that ended exclusivity.
