A 10%+ surge in Seoul trading on Wednesday pushed the Korean memory firm past $1 trillion, making it the third chipmaker after Nvidia and TSMC to cross the line.
SK Hynix’s market capitalisation pushed through $1 trillion in Seoul trading on Wednesday morning, on the back of a single-session rally of more than 10% that briefly tripped circuit breakers on South Korea’s benchmark Kospi index.
The Korean memory firm becomes the third chip company ever to cross the trillion-dollar mark, after Nvidia and TSMC, and the first dedicated memory specialist to do so.The milestone arrives at the end of a stretch that has been, by any normal benchmark, structurally implausible.
SK Hynix’s share price has risen roughly 900% over the past 24 months. Last month, the company sat about $50bn below the trillion-dollar threshold; the closing gap reflects how violently the high-bandwidth memory (HBM) cycle has compressed into the company’s books. Full-year 2026 HBM capacity is sold out. Shortages are forecast to persist through 2027.

UBS estimates the company holds roughly 70% of HBM4 orders for Nvidia’s Vera Rubin platform, which Jensen Huang described in Taipei this week as “probably the largest product launch in the history of Taiwan.”
