Bottom line up front

The semiconductor boom is very likely structural through 2027, not a normative cyclical peak. Convergent primary signals — Gartner's $1.32T 2026 forecast at +64% YoY[B1], TSMC's raised above-30% USD growth guidance on a 66.2% gross margin[A1], and triple-digit YoY revenue at Taiwan AI-server ODMs (Wistron +117.7%, Quanta +88.4%)[C3] — mark a durable AI-driven expansion. The dominant risk has shifted from demand softness to forced US–China stack decoupling: the MATCH Act (H.R. 8170), TSMC's $165B Arizona buildout, and ASML China sales falling 36%→19% make structural bifurcation by 2028 likely regardless of the bill's passage.[B2] Confidence is high on the supercycle, moderate on the policy timeline.

4 Key Judgments

KJ-01

Global semiconductor revenue will very likely exceed $1.3T in 2026 and sustain double-digit growth through 2027, driven by AI-infrastructure capex rather than broad-based cyclical recovery.

Confidence: HighSources: A1 · A2 · B1, convergent
KJ-02

The US and China will very likely complete structural decoupling of the advanced semiconductor stack by end-2028, with ASML China revenue falling under 10% of sales and Chinese foundries locked into a parallel non-EUV track.

Confidence: HighSources: B2, multi-source trend
KJ-03

The MATCH Act (H.R. 8170) is likely to clear House Foreign Affairs Committee, though full passage and Dutch/Japanese alignment within the 150-day window remain uncertain and are the primary near-term trigger for supply-chain volatility.

Confidence: ModerateSources: B2, legislative tracking
KJ-04

Memory memflation (DRAM +125%, NAND +234%) is likely to delay non-AI demand into 2028, creating a two-track environment where AI-aligned buyers capture priority capacity while price-sensitive enterprise IT defers refresh, cross-pressuring the supercycle thesis unevenly across the stack.

Confidence: ModerateSources: B2, Gartner (Rajput)
