The thesis

Broadcom sells custom AI accelerators and networking chips to Google, Meta, and Apple, plus infrastructure software. Revenue grew 85.5% year over year, gross margin is 68.8%, and net margin is 42.9%. Analysts rate the stock a buy at 37.5 times earnings. Our conviction score sits at 5 out of 100, dormant, because the AI capital spending driver is flagged inactive. The market prices structural growth that our signal says has not yet reactivated.

Why now

TSMC reportedly plans up to a 20% price hike on advanced chip packaging, and Broadcom pays TSMC, so margin pressure lands just as growth peaks. Nvidia's instruction to data center partners to limit China sales tightens the whole AI supply chain. Cost inflation now collides with a dormant demand signal, and that collision is mispriced.

What to watch

Watch whether the AI capital spending signal reactivates and whether gross margin holds near 68.8% after packaging costs rise. Watch upcoming quarterly custom silicon revenue concentration across Google, Meta, and Apple for confirmation that the backlog is broadening rather than peaking.

Key risks

A 37.5 times multiple assumes the custom silicon backlog converts without margin erosion, and a 20% packaging price hike tests that directly. If hyperscaler AI capital spending slows, the structural revenue narrative loses its base. China sales restrictions add a second policy variable that could compress demand across the cluster.
