✦ The OpenAI Deal & the 10-Gigawatt OrderNarrow moat

The October 2025 announcement read like a treaty: OpenAI designs the accelerators and the systems, Broadcom develops and deploys them — ten gigawatts' worth, racks scaled entirely with Broadcom Ethernet, first deployments in the second half of 2026 and completion targeted by the end of 2029¹. It slotted into OpenAI's larger buying spree — roughly 26 gigawatts committed across Nvidia, AMD and Broadcom — and the market added about 9% to Broadcom's value the morning it learned who the mystery customer was².

What makes the order a bet rather than a booking is the counterparty. OpenAI is the most ambitious spender in the industry and also its most creatively financed: the racks serve a company whose commitments dwarf its revenue, and ten gigawatts is a promise about 2029 made in the currency of 2025's enthusiasm. Broadcom's protection is structural — the customer owns the design and the capex while Broadcom collects on delivery — but a scaled-back OpenAI would still shrink the backlog that justifies the multiple. Watch the H2 2026 first racks land on time, and watch each subsequent gigawatt get funded, because the difference between 10GW announced and 10GW energized is measured in tens of billions of dollars.
