Buffett's Firm Bets Big on AI-Powered Alphabet
23 Nov, 2025
Summary
- Berkshire's Alphabet stake gained $415 million in a week.
- The surge occurred amid positive reviews of Google's Gemini 3 AI.
- The investment fuels debate about Berkshire's approach to risk.
Berkshire Hathaway's investment in Alphabet has seen a dramatic increase of $415 million in value over the past week, bringing the total stake to nearly $5.35 billion. This surge, propelled by an 8.4% rise in Alphabet's stock, has reignited discussions about the conglomerate's investment philosophy.
The rally appears to be linked to both the disclosure of Berkshire's substantial purchase of 17.8 million Class A shares and the positive market reception of Google's newly unveiled Gemini 3 AI model. While Alphabet shares climbed, several of its tech rivals experienced declines, underscoring the market's current focus on AI advancements.
This significant and rapid gain has led analysts to question whether the investment aligns with Warren Buffett's traditional risk-averse strategy or represents a new direction possibly spearheaded by portfolio managers Ted Weschler and Todd Combs, hinting at a potential strategic shift within Berkshire Hathaway.
