Greg Abel Piles Into Nvidia Stock as Other Billionaires Dump

In the first quarter of 2026, Greg Abel, CEO of Berkshire Hathaway (BRK-B) and Warren Buffett's successor, significantly increased the company's holdings in Nvidia (NVDA), according to portfolio disclosures. The move comes at a time when several billionaire hedge fund managers are reducing their exposure to the stock, sparking debate about Abel's rationale.

Details of the Move

While the exact number of shares purchased was not disclosed, filings indicate that Berkshire strengthened its Nvidia position during Q1 2026. The stock was trading at a price-to-earnings ratio of approximately 30x at the time, a relatively high multiple compared to the broader market.

Possible Reasons

• Long-term growth confidence: Abel may believe Nvidia will continue to benefit from strong demand for AI chips.
• Diversification: Berkshire's portfolio is heavily weighted toward financial and industrial sectors; adding tech exposure could be strategic.
• Contrarian bet: Abel might view the mass exodus as a buying opportunity.

Context

Meanwhile, several prominent hedge funds, including those run by billionaires Stanley Druckenmiller and David Tepper, have trimmed their Nvidia positions. This divergence highlights the split opinion on the stock's valuation.

What It Means for Investors

Abel's move does not constitute a buy recommendation, but it suggests that some long-term investors see value in Nvidia even at elevated multiples. Investors should weigh the risks of high valuation and competition in the chip market.
