Short term (within 3 months): SK Hynix’s U.S. listing, which would raise about $29 bln, is likely to reallocate liquidity across the AI/memory cohort, so Hynix and Micron are more likely to move together than to show pure market-share transfer. A Hynix rally accompanied by a Micron sell-off would signal tighter-than-expected AI-sector liquidity and would likely prompt more cautious positioning ahead of an Aug–Oct pullback. Mid term (6–18 months): competition will center on HBM4. Current share split is roughly SK Hynix 56%, Micron ~21%; 2026 HBM4 forecasts point to Hynix 54%, Samsung 28%, Micron 18%. The ~$29 bln raised will be directed to new fabs and EUV tools, materially increasing Hynix’s capital edge. The industry remains supply-constrained and profitable, but Micron can no longer rely on being the sole U.S.-listed memory play to avoid competitive pressure. Political support for Micron from Trump could blunt downside risk, so a severe mid-term loss appears unlikely. Long term (2027+): outcomes hinge on who weathers a possible 2028–29 oversupply. Hynix’s ~$29 bln equity infusion strengthens its balance sheet and liquidity buffer relative to Micron, representing the most enduring structural disadvantage for Micron if a prolonged downturn occurs. — Analyst Emily Scarlet(金十数据)
