TSMC's CoWoS advanced packaging capacity is now sold out with no near-term relief, and that single constraint is reshaping the entire AI hardware supply chain. In today's briefing, we unpack what that bottleneck means for hyperscalers, chip designers, and investors tracking the infrastructure layer of AI.

Google has committed to over three million TPU chips from Intel's foundry through 2028 — roughly half of Google's projected TPU output for that year. It is the clearest validation yet that Intel Foundry has moved from aspiration to execution. At the same time, Nvidia is running multi-project wafer tests on Intel's 18A process node for a four-die GPU design tied to the next-generation Feynman architecture. Evaluation is not commitment, but hardware validation at this scale is a meaningful signal.

TSMC's Q1 results confirmed the pressure driving all of this: $35.9B in revenue, 66.2% gross margins, and net income up 58%. The 2nm volume ramp in 2027 is now the critical path for next-generation AI GPUs.

SK Hynix is supplying HBM4 memory across all four of Nvidia's next-gen platforms using MR-MUF bonding targeting 16-layer stacks in H2 2026 — an ambitious and unproven spec at volume. The SK-Nvidia relationship has moved well beyond transactional supply toward something closer to vertical integration.

AMD announced a multi-billion pound UK initiative spanning Dell, Cambridge, Imperial College, and the UK Atomic Energy Authority. Broadcom, Apollo, and Blackstone launched a $35B platform targeting 20-plus gigawatts of global AI infrastructure, with the first tranche funding Anthropic's capacity expansion via Fluidstack.

Watch Intel's 18A yield data and TSMC's 2nm ramp in H2 2026. Those are the two metrics that will determine how much of this diversification story actually delivers.
