Warren Buffett's Berkshire Hathaway has tripled its stake in Alphabet, Google's parent company, to $16.6 billion, according to The Cryptonomist. The move marks a notable vote of confidence from one of the world's most closely watched investors in a company at the center of the artificial intelligence race.
The timing lines up with fresh signs of strength in Alphabet's cloud business. According to Seeking Alpha, Google Cloud is outperforming its two larger rivals, Microsoft's Azure and Amazon's AWS. The same analysis points to a $462 billion backlog — a measure of contracted future revenue — that Seeking Alpha says will require Alphabet to keep ramping up its AI investments to fulfill.
That backlog is a double-edged signal. On one hand, it suggests deep, committed demand for Google's cloud and AI services. On the other, delivering on those commitments means heavy ongoing spending on data centers, chips, and infrastructure — costs that can weigh on near-term profits even as they build long-term capacity.
For Berkshire, known for its disciplined, value-oriented approach, a tripled position in a major AI player is a meaningful shift. It suggests Buffett's firm sees durable value in Alphabet rather than treating it as a speculative tech bet.
Why it matters: when one of the most cautious investors in the world makes a large new bet on a company whose cloud arm is now beating Amazon and Microsoft, it signals that the AI buildout is increasingly being viewed as a long-term business with real, contracted demand — not just hype.
