A five-session rally tied to AI agent demand made AMD a trillion-dollar chipmaker, strengthening a currency it already uses in warrants for two large AI customers, OpenAI and Meta.
The joint venture moved from plans to serving customers on MI355X systems, with MI400-series capacity due from the second half of 2027 and a 1 gigawatt target by 2030.
Director KC McClure took over audit oversight as AMD took on a $4.75 billion notes offering, a pending acquisition and warrants tied to its biggest AI customers.
AMD did not disclose terms for the Toronto startup, whose model-specific silicon is built to run trained AI models faster and with less power than general-purpose chips.
AMD claimed up to 30% more tokens per dollar than Nvidia's Vera Rubin NVL72, and said OpenAI expects to bring Helios online from the fourth quarter of 2026.
AMD said Helios shipments to customers including Microsoft start in the second half of 2026; neither company disclosed deployment scale or financial terms.
