- Amazon completed its $50 billion investment in OpenAI, with the AI lab receiving the final tranche of the equity deal this week.
- Amazon now holds roughly a 5% stake in OpenAI, making the e-commerce giant a significant minority owner of the AI lab following the completed transaction.
Why it matters: A $50 billion equity check for roughly 5% of OpenAI locks Amazon into a minority-ownership position at one of the most compute-intensive AI labs, converting a commercial relationship into a direct cap-table stake during a period of escalating AI infrastructure spending.
