Five hyperscalers control about 71% of global AI compute, so access to capacity and pricing for most builders depends on a few providers. The share rose from 63% in early 2024.
Key takeaways · AI-distilled
Epoch estimates that Amazon, Google, Meta, Microsoft and Oracle held about 71% of global AI compute in Q4 2025, up from 63% in Q1 2024, based on its chip ownership data.
The comparison converts chips into H100-equivalents using their highest 8-bit operations-per-second specifications. This enables aggregation across vendors but does not capture workload-dependent performance differences.
The ownership dataset is incomplete and coverage is weaker before 2023. The article excludes Q1 2026 from its analysis because those data were not finalized, even though the displayed table includes that quarter.
