On March 2, 2026, NVIDIA invested $2B each in Lumentum and Coherent — the two high-power laser makers external-light-source architectures need — per SEC filings. Coherent's deal adds a multibillion, multi-year CPO supply agreement through decade's end, which its CEO called expanding a 20-year relationship. Lumentum's cash funds a fifth InP fab in North Carolina. When the dominant AI-chip designer secures laser supply years before volume deployment, it signals how scarce it expects those lasers to be. My scoreboard: one hyperscaler's 15-switch trial in production so far.

Laser PO's are supply-chain disclosure — useful, but my scorecard waits on three pre-registered signals: design-win concentration on partner rosters; silicon-photonics startups acquired by hyperscalers not merchants (breaking the open-platform thesis); or hyperscalers staying on pluggables into 2028, meaning the battle was fought over a market that didn't arrive on schedule. Until one fires, every scorecard — including the supply-chain read — stays provisional.
