Berkshire Hathaway Takes $4.3 Billion Alphabet Stake as It Cuts Apple and Bank of America

The move signals a cautious tilt toward AI-heavy platforms during a record cash buildup ahead of a leadership handoff.

Overview

  • Berkshire disclosed ownership of 17.85 million Alphabet shares as of Sept. 30, a roughly $4.3 billion position that now ranks among its top 10 holdings.
  • The conglomerate trimmed Apple to 238.2 million shares from 280 million in Q3, though the iPhone maker remains its largest equity holding at about $60.7 billion.
  • The firm sold about 37.2 million Bank of America shares, leaving a roughly 7.7% stake, and continued other portfolio adjustments including an exit from D.R. Horton and additions such as Chubb and Domino’s.
  • Berkshire was a net seller for the twelfth straight quarter, buying $6.4 billion and selling $12.5 billion of stocks as cash rose to a record roughly $381.7–$382 billion.
  • It remains unclear whether Warren Buffett or investment managers Ted Weschler and Todd Combs initiated the Alphabet purchase, and Alphabet shares rose about 1.7% after hours following the disclosure as Berkshire prepares to transfer the CEO role to Greg Abel on Jan. 1, 2026.
