Short Sellers Keep Placing Their Bets Against Micron Stock. Why They Think MU Will Stumble Soon.

For much of the artificial-intelligence (AI)-driven semiconductor rally, Micron Technology (MU) has been one of Wall Street’s hottest trades, fueled by explosive demand for high-bandwidth memory chips and tightening DRAM supply. But while bullish investors continue to chase the AI narrative, short sellers are quietly building a sizable bet that the rally may be nearing exhaustion.

Short interest in Micron has climbed to roughly 37.3 million shares, near the highest levels seen in years, after rising steadily through 2026. This represents 3.32% of the public float. The latest data shows bearish positions increased another 2.6% in late April following a 15.9% jump earlier in the month.
