Google Loses $500B in 12 Hours | DoorDash Buys Instacart for $17B | Kalshi Raises $1B

With Harry Stebbings, Jason Lemkin, Rory O’Driscoll · Thursday, November 5, 2026

Harry Stebbings, Jason Lemkin, and Rory O'Driscoll analyze major shifts across the tech landscape, from OpenAI's valuation adjustments and Anthropic's growth metrics to DoorDash acquiring Instacart for $17 billion.
