OpenAI and Broadcom announce strategic collaboration to deploy 10 gigawatts of OpenAI-designed AI accelerators

OpenAI and Broadcom announced a multi-year deal to deploy 10 gigawatts of OpenAI-designed AI accelerators, with rack deployments starting in H2 2026 and completing by the end of 2029. OpenAI will design the accelerators and systems, while Broadcom provides accelerator deployment plus Ethernet, PCIe, and optical networking for OpenAI sites and partner data centers. The key signal is OpenAI's custom-chip plus Ethernet cluster path, but the post does not disclose process node, chip specs, or capex.

Why it matters: Not a routine partnership story: OpenAI put a 10GW custom-chip plan and a 2026-2029 deployment schedule on record. HKR-H/K/R all pass, but process node, per-chip specs, and capex are still undisclosed, so this lands in p1 rather than 95+.
