Warren Buffett said he personally drove Berkshire Hathaway’s recent push into artificial intelligence investments, including the purchase of Alphabet stock [1].

The admission is significant because Buffett has historically been cautious regarding emerging technologies. His direct involvement suggests a strategic shift in how the conglomerate views AI as a long-term value driver rather than a speculative trend.

In a message to investors this month, Buffett said, "It was me" [2]. The confirmation addresses questions regarding whether the company's pivot toward AI was led by newer executives or the founder himself [1].

Despite the investments, the 95-year-old investor cautioned the public against excessive gambling on AI stocks [3]. He said to "be careful" when navigating the current market environment [4]. This warning comes as the broader market continues to experience high volatility surrounding AI-related assets.

Buffett's strategy is backed by significant liquidity. Berkshire Hathaway currently maintains a cash pile of $380 billion available for investment [5]. This massive reserve allows the firm to take calculated positions in companies like Alphabet without compromising its overall financial stability.

The move into Alphabet reflects a targeted approach to AI. Rather than investing in a wide array of startups, Buffett has focused on established entities with existing infrastructure, and data advantages [1].

This balance of aggressive investment and public caution is typical of Buffett's value-investing philosophy. By acknowledging his role in the AI trade, he signals that the technology has met his rigorous standards for business viability, even as he warns against the surrounding hype [2].

"It was me"

Buffett's confirmation indicates that Berkshire Hathaway is no longer merely observing the AI revolution from the sidelines. By leveraging a $380 billion cash reserve to enter the sector via established giants like Alphabet, Buffett is applying a 'value' lens to AI—prioritizing companies with sustainable competitive advantages over speculative growth. His simultaneous warning to investors suggests he believes the sector is currently prone to overvaluation, despite its fundamental utility.
