Berkshire Hathaway’s (BRK.A) (BRK.B) Q2 2026 13F revealed that the company added another $17 billion worth of Alphabet (GOOG) (GOOGL) shares in the quarter. The news wasn’t surprising, as the conglomerate previously disclosed that it invested $10 billion in Alphabet’s private share placement as part of an $80 billion capital raise, which was intended to build the war chest for the Google parent’s burgeoning artificial intelligence (AI) investments. The quantum of share purchases in the quarter, however, suggests that Berkshire likely added another $7 billion through open market purchases.
