All past briefs, most recent first.
Today's news strongly validates the substrate-constraint thesis. TSMC beat Q1 and guided up, confirming leading-edge fab demand remains the binding constraint. ASML reported strong sales but flagged 'supply chain challenges' — the bottleneck is tool delivery, not chip design. BWXT announced a new uranium enrichment facility, directly addressing nuclear fuel supply constraints, while the White House launched a space nuclear power initiative lifting the entire nuclear complex. The Terafab (Tesla/SpaceX JV) scrambling to procure chipmaking gear underscores that physical fab capacity, not algorithms, is the scarce resource.
Today's news strongly reinforces the substrate-constraint thesis. ASML reported an earnings beat but guided down China revenue due to export bans — the EUV bottleneck is tightening geopolitically, not easing. META-AVGO multi-year custom ASIC deal, BWXT announcing a new uranium enrichment facility, and Williams breaking ground on Northeast Supply Enhancement all confirm that physical buildout (silicon, fuel, pipelines) is the binding constraint. No cracks in the thesis; if anything, the ASML China restriction and hyperscaler capex narratives are accelerating the substrate scarcity premium.
