🔔 The Daily Semi-Cap — May 19, 2026

📊 SMH: $543.96 (-0.40%)

📈 Earnings:

• No new semiconductor earnings released today.

🔥 Major Developments:

• OpenAI launched Guaranteed Capacity, letting enterprise customers lock in 1-3 year access to compute with discounted token commitments. The product is basically a demand signal in disguise: frontier AI customers are now buying capacity certainty, not just model access.

• Aixtron said Lumentum ordered multiple G10-AsP MOCVD systems for InP-based laser and detector production, tied directly to AI data-center network demand. The InP laser capacity race is moving from commentary to tool orders.

• YMTC parent Yangtze Memory Holdings submitted listing tutoring materials with Chinese regulators, setting up a potential IPO path. That would give China’s domestic NAND champion a public-market funding channel just as memory sovereignty keeps moving up the stack.

• Evercore’s latest AI silicon work flagged hyperscaler pushback on Nvidia’s 35x TCO claim, especially around power and cooling overhead, while also noting no major hyperscaler bring-up issues for Rubin and mass-production shipments expected in 2Q26.
