Q: What is the main risk in the Custom Silicon theme?

Google Internalization / Nvidia Counter-Cycle Google's Apr 2026 TPU split kept Broadcom on training (deal to 2031) but handed inference to MediaTek, not in-house — diversification, not internalization, but still dilutes Broadcom's inference share; Nvidia Vera Rubin cost-per-token improvement remains the second watch item

Q: What stage is the Custom Silicon theme at?

Design-Win Revenue at Scale Amazon $20B ARR, Broadcom $73B backlog — ASIC revenue is contracted and growing

Q: How strong is Northstar's conviction on Custom Silicon?

High Contracted revenue and 44.6% CAGR momentum confirm thesis; concentration risk is the monitoring variable

Semiconductor & Advanced HardwareSemiconductors Updated 2026-08-28

The hyperscaler custom silicon race has crossed a commercial inflection: Google, Amazon, Microsoft, and Meta have all moved purpose-built ASICs from R&D into production at scale, creating a 44.6% CAGR market that routes primarily through a Broadcom-Marvell design duopoly controlling roughly 95% of co-design capacity and fabricated almost entirely on TSMC's most advanced nodes.

📈 What changed: 2026-08-17: SemiAnalysis cut its Broadcom-designed Google TPU shipment forecast -- 2026 TPU v7 (Ironwood) output revised from 3.2M to 2.7M units and Broadcom's 2026 CoWoS packagin…

Six-indicator scorecard

Indicator	Score	Reading
Maturity higher is better · high confidence	82/100	Production-scale deployment across all five major hyperscalers; Broadcom-Marvell duopoly revenue confirming commercial reality.
Evidence Strength higher is better · high confidence	71/100	Bloomberg Intelligence + company earnings + financial press provide strong cross-corroboration; no peer-review layer.
Commercial Proximity higher is better · high confidence	85/100	Revenue at scale now; 65% TCO advantage for inference is already displacing GPU spend at production deployments.
Capital & Policy Support higher is better · high confidence	52/100	Theme is private-capex-driven; CHIPS Act and AI policy provide indirect support via TSMC US fabs.
Crowding Risk lower is better · high confidence	85/100	Broadcom and Marvell are among the most-owned and most-valued AI semiconductor plays alongside Nvidia.
Reflexivity Risk lower is better · high confidence	47/100	Names correlated to AI narrative but anchored in real contracted revenue; less reflexive than pure AI plays.
