OpenAI will spend billions of dollars on AMD's chips in a new multiyear deal announced Monday, with the ChatGPT-maker potentially taking up to a 10% share of the U.S. semiconductor firm.

Why it matters: The AI revolution has an unquenchable hunger for computing power, and OpenAI is trying to lock down suppliers beyond market leader Nvidia.

By the numbers: OpenAI said it expects to have the first 1 gigawatt (out of a projected 6 total) of AMD's Instinct processors up and running in the second half of 2026.

The big picture: Nvidia recently cut a deal with Intel to invest $5 billion in the troubled U.S. chipmaker. In August the Trump administration said the U.S. government would receive a 10% stake in Intel in return for billions in grants under the CHIPS Act.

Between the lines: AMD, like Nvidia, designs chips but manufactures them through Taiwan-based TSMC. Intel is the chief U.S.-based manufacturer of microprocessors.
