AMD posts $5.8B Q1 2026 data center revenue (+57% YoY) — MI400 launches H2 with 432GB HBM4 and 40 PF FP4, $120B 2030 server CPU forecast

AMD's Q1 2026 data center revenue reached a record $5.8B, up 57% YoY, with Instinct MI325X and MI300X driving the upside. CEO Lisa Su called the results 'a clear inflection in our growth trajectory and a structural shift in our business.' AMD also disclosed the Instinct MI400 launch for H2 2026 with 432GB of HBM4 and 40 petaflops of FP4 compute, and a $120B 2030 server CPU revenue forecast.

The structural read confirms AMD's second-source-becomes-primary-procurement transition is now visible in the financials. The MI300 procurement validation from the AM cycle had OpenAI and Meta committing roughly 12GW combined to AMD Instinct deployments (~$60B in multi-year deals). The Q1 print is the leading-edge revenue effect of those bookings; H2 2026 will show whether MI400 sustains the growth or whether the inflection plateaus.

For NVIDIA, the market-share data is now public: accelerator share slipped from above 90% in 2024 to roughly 68% in early 2026. NVIDIA's absolute revenue is still climbing because the AI accelerator market is growing faster than competitor share gains. But the trajectory — 90% to 68% in 18 months — is the strongest counter-signal to the 'NVIDIA forever' procurement default.
