Warren Buffett’s Accidental AI Windfall

Berkshire’s 2000 acquisition of MidAmerican Energy, a utility provider serving Iowa and the Midwest, was never intended to fuel a technological revolution. Yet, as AI demands unprecedented amounts of electricity to sustain its massive computing requirements, Iowa has transformed into a critical data center hub. This development has turned a legacy utility deal into one of Berkshire’s most profitable indirect AI plays. Ken Mahoney, president and CEO of Mahoney Asset Management, notes that the move serves as a reminder that boring industries often yield the most consistent long-term returns.

The strategy extends to Berkshire’s 2016 purchase of Precision Castparts, a manufacturer of turbine components. The deal was originally considered a financial failure, marked by Buffett’s admission of overpayment and an $11 billion write-down. Today, those same turbines are essential for generating the power required by data centers, turning a previous liability into a vital asset. Cathy Seifert of CFRA Research emphasizes that this outcome was driven more by fortune than foresight, as the company lacked a specific strategy to leverage AI during these acquisitions.
