Berkshire Hathaway boosts Alphabet stake by $17 billion

Berkshire Hathaway has increased its stake in Google's parent company Alphabet by $17 billion. According to CNBC, Alphabet became the third-largest stock position in Warren Buffett's investment company's equity portfolio on August 15, 2026.

The move comes as institutional investors are repositioning their holdings in the technology sector. While Berkshire is adding to its Alphabet position, other prominent investors have reshuffled their portfolios: Stanley Druckenmiller rotated out of positions such as Broadcom, Intel and Micron into Amazon and AMD in the second quarter of 2026, as Benzinga reports.

AI and cloud business in focus

The investment coincides with ongoing discussions about Alphabet's capital expenditures in artificial intelligence. Like other tech companies, the company faces the challenge of justifying massive investments in AI infrastructure. Industry observers point to strong growth in cloud business and AI applications as driving factors.

Alphabet is investing significantly in autonomous mobility services: the company's own Waymo unit is developing robotaxi services, whose growth potential is considered substantial by analysts. SeekingAlpha published an analysis on August 16, 2026, on projected growth in autonomous ride-hailing services by company.

Technology sector under investment pressure

The entire technology industry continues to record high spending on AI infrastructure. Nvidia, AMD, Cisco, Intel and other semiconductor companies announced new investments, partnerships and infrastructure initiatives in the week of August 10-14, 2026, as Benzinga reported.

Analysts view Alphabet's valuation as compressed following recent price declines. SeekingAlpha argued on August 15, 2026, that the market reaction to rising capital expenditures was unwarranted, given the growth dynamics in the AI and cloud segment.

Berkshire's stake increase underscores the confidence of institutional investors in Alphabet's long-term positioning in artificial intelligence and cloud computing. Warren Buffett's holding company is known for long-term value investments in companies with stable business models.
