Berkshire — the board's largest true dry powder and famously the tech-skeptic conglomerate — built a fast-growing Alphabet position ($4.3B disclosed Q3'25 → ~$28-41B incl. a $10B AI-infra private placement Jun'26) that Buffett himself frames as an AI-capex bet, even as new CEO Abel says "we're not going to do AI for the sake of AI." Track: the Q2 2026 13F for whether the position kept growing or any other AI-adjacent name appears, and further Buffett/Abel commentary. Secondary, lower-priority strand: GEICO's June 2026 PA AI-underwriting settlement and a reported (unconfirmed-subsidiary) AI-liability policy exclusion — industry pattern more than Berkshire-specific.
