Samsung's $1 Trillion Moment: AI Chip Frenzy Sends Stock Soaring Nearly 10%

The Rally That Rewrote The Record Books

Samsung Electronics hit a historic milestone in May 2026 after its stock posted one of its largest single-day gains ever, briefly surging over 15% before settling around the 9.9% mark. The South Korean chipmaker became only the second Asian corporation, after TSMC, to breach the $1 trillion market cap barrier.

What Ignited The Fire

Multiple catalysts converged to power this rally. Samsung reported Q1 operating profits more than eight times higher year-on-year, clocking 133.9 trillion Korean won in revenue. On top of that, reports surfaced of Apple entering early-stage discussions with Samsung to manufacture chips for its U.S.-bound devices, reducing reliance on TSMC.

Strike Resolved, Uncertainty Cleared

An 11th-hour wage deal with the 48,000-member union, brokered by the South Korean government, eliminated strike risk and added fresh momentum. JP Morgan responded by maintaining its Overweight rating, calling the labour resolution a clear signal removing a key overhang on the stock.

Chips At The Centre Of It All

Samsung also began shipping samples of its latest high-bandwidth memory chips to global customers, a move that directly fuelled investor optimism around its AI semiconductor roadmap. SK Securities raised its target price to 500,000 won, implying nearly 87% upside from pre-rally levels.
