YC Startup School 2026

Notes on the five talks from Y Combinator's Startup School 2026. One chapter per speaker in playlist order, written from the transcripts and kept to what each speaker actually argued.

• Alexandr Wang — A Once-in-a-Civilization Opportunity
• Blake Scholl — Breaking the Supersonic Ban
• Sam Altman — Never a Better Time to Do a Startup
• Boris Cherny — We Cut 80% of the Prompt
• Jensen Huang — The Mindset That Built NVIDIA

Four claims recur across speakers who had no reason to coordinate: conviction nobody shares is the asset rather than the risk, the constraint has moved from capability to ambition, systems thinking survives while specifics do not, and be empirical.
