The $600B Giant That Fell From Grace — And Drew Buffett’s Billions

A healthcare titan collapses nearly 50% in 2025, but Buffett’s bet signals the market may have overreacted.

Wall Street loves a clean story: growth darlings keep rising, healthcare is defensive, and the biggest players are untouchable. But every once in a while, a behemoth stumbles so hard it rattles an entire sector. Investors panic. Analysts rewrite models overnight. Pundits swarm in with “I told you so’s.”

And yet—when the dust clears, the smartest money in the world doesn’t run. It quietly walks in and writes a massive check. That’s exactly what just happened in one of the most systemically important companies in America, a firm that touches nearly every household in the country—directly or indirectly—through insurance, data, or care delivery. Its stock has cratered nearly 50% in less than a year, leadership has been thrown into chaos, regulators are circling, and the press is hammering its reputation.

On paper, it looks like a mess. But in practice, it might be one of the most asymmetric bets of the decade. Because when Warren Buffett opens the playbook and calls this an opportunity worth $1.6 billion, you pay attention.
