Buffett’s New Quantum Computing Favorite
Warren Buffett’s Berkshire Hathaway has shifted its investment focus to Alphabet Inc. (NASDAQ: GOOG), acquiring over 17.8 million Class A shares valued at more than $5 billion in Q3 2025. This new position in Alphabet represents more than twice the size of Berkshire’s previous stake in Amazon, which was its only quantum computing investment prior to this.
Alphabet’s Google Quantum AI has achieved significant milestones, including a computation in 2019 that would have taken supercomputers approximately 10,000 years to complete. Notably, the company’s advertising revenue also remains strong, generating $74.2 billion in Q3 2025.
