8 Billionaire Money Managers Dumped Micron in the Second Quarter, With Several Favoring This Foundational AI Stock Instead

Eight billionaire money managers dumped MU shares during Q2 2026, likely locking in gains after the stock quadrupled from its March lows. The exits mark a notable shift in sentiment among high-profile investors who rode MU's sharp rally tied to memory chip demand in AI applications.

Five prominent billionaires rotated into TSM instead during the same quarter. The foundry giant commands a 72% share of global contract chip manufacturing and serves as the linchpin for AI data center buildouts. TSM's earnings per share are projected to more than double between 2025 and 2027, a growth trajectory that appears to have attracted capital flowing out of MU.

The divergence underscores a preference among some large investors for the picks-and-shovels foundry play over the more volatile memory chip segment. TSM manufactures cutting-edge processors for nearly every major AI hardware vendor, positioning it as a direct beneficiary of infrastructure spending regardless of which chip architecture wins market share. MU, while benefiting from surging high-bandwidth memory demand, faces cyclical pricing headwinds and inventory dynamics that can compress margins quickly.
