Micron Cracks $1,000 as DRAM Lawsuit and Oversupply Fears Bite

The Break Under $1,000

MU is changing hands at $985.40, off 5.13% over the last 20 hours and now printing below the round-number $1,000 level that had acted as a floor since the post-earnings run. The stock is roughly 22% off its late-June highs even after a 250% year-to-date gain, so this is a give-back inside a much larger move, not a trend break. But the psychology matters: $MU heading under $1,000 removes a level a lot of the June dip-buyers were leaning on, and it comes after Michael Burry disclosed a short near $1,051.87 calling the name a destroyer of capital. Thin holiday-week liquidity is amplifying the tape.

The [DRAM](/movers/dram) Antitrust Overhang

The fresh company-specific catalyst is legal. A newly filed U.S. class-action names Micron alongside Samsung and SK Hynix, alleging the three deliberately restricted output of conventional DDR3 and DDR4 DRAM while shifting capacity toward higher-margin high-bandwidth memory for AI servers. The three control roughly 90% of the global DRAM market, so the suit reopens the pricing-collusion scrutiny that has dogged the industry for a decade. It's an overhang, not a fundamental hit — but it gives the profit-takers a headline to sell into, and it lands right as the AI-hardware trade is already rotating toward software.

The Glut Question and SK Hynix

The structural worry is oversupply. Investors are pricing the risk that planned Korean capacity expansions tip the memory cycle into a glut, undercutting the exact HBM pricing power that drove Micron's blowout guide — Q4 guided to ~$50B against a ~$43B consensus. Layer on the SK Hynix Nasdaq ADR listing expected around July 10: a fresh, liquid, pure-play memory comp will re-mark every name in the group at once and hands US investors a direct alternative to MU. The bull counter is that Wall Street has been raising out-year EPS estimates, so the debate is entirely about the multiple, not the demand.
