Berkshire Hathaway's Q1 2026 13F shows a $263.1B equity portfolio that contracted from $274.2B a quarter earlier, but the headline is positional rather than directional: a newly disclosed $15.6B Alphabet (GOOGL) position now sits at 5.9% of the book after a roughly 204% increase in share count, vaulting into the top seven alongside the long-standing core of Apple (22.0%, $57.8B), American Express (17.4%, $45.9B) and Coca-Cola (11.6%, $30.4B). The quarter was defined by selectivity over churn: Berkshire trimmed Bank of America (-$3.4B) and cut Chevron share count by roughly 35% (-$2.4B), exited the Constellation Brands stake (-95% share count) entirely, and opened a $2.6B Delta Air Lines position. With 16 positions left unchanged and only three new buys against sixteen exits, the filing reads as a deliberate concentration into mega-cap technology and away from cyclical banking and energy exposure.
