Berkshire holds about $30 billion worth of Alphabet shares, lower than the June peak

Given that Alphabet (GOOG.US) announced disappointing third-quarter results and its share price subsequently fell sharply—at one point dropping over 10% after hours—Warren Buffett's last major stock investment during his tenure as chairman of Berkshire Hathaway is currently underperforming. In the first half of 2026, Berkshire made substantial purchases of Alphabet shares. In early June, Berkshire participated in Alphabet's $85 billion share issuance, buying $10 billion worth of shares at approximately $350 per share. In July, Buffett stated that buying Alphabet stock was his personal decision. It is currently unclear what Berkshire’s average cost for Alphabet shares is, but it is likely above $300 per share and could be close to $320. As of June 30, Berkshire held a total of 106 million Alphabet shares; based on after-hours prices, this holding is worth around $30 billion, down from the $37 billion peak reached in June. Alphabet is Berkshire’s fourth largest equity holding, trailing only Apple, American Express, and Coca-Cola.
