Amazon completes $50bn investment in OpenAI

Amazon has closed its $50bn investment in OpenAI, making it one of the startup's most critical financial backers. The deal deepens the tie-up between AWS cloud infrastructure and OpenAI's model layer. The article body only provides the headline; it does not disclose deal structure, equity stake, or specific compute supply terms.

Why it matters: A $50bn investment from Amazon into OpenAI is a landscape-shifting deal that redraws the cloud-model lab power map. FT is a strong source, but the body only has a headline — no payment schedule, equity stake, or compute supply terms disclosed, so the score stays below 85.
