U.S. semiconductor shares jumped in premarket trading Tuesday, extending gains from artificial intelligence-driven rallies across Asian markets. Micron Technology climbed 4.9% to $36.50, while Arm Holdings added 3% ahead of broader market open.

The tech-heavy Nasdaq led major indexes with an 0.8% premarket rise, building on a seven-of-eight-week winning streak. Marvell Technology surged 5.4% before its first-quarter earnings report Wednesday, with SanDisk and Qualcomm gaining 2.9% and 2.5% respectively.

Chip stocks are playing catch-up to Asian technology advances, particularly in Hong Kong and South Korea markets. The rally follows a holiday-shortened trading week, with the Nasdaq closing Friday at its third-highest level amid sustained momentum.

Geopolitical developments provided mixed signals as peace talks between the U.S. and Iran boosted sentiment, though exchange strikes between both sides prompted some profit-taking in futures. The semiconductor sector's premarket strength suggests investors remain focused on AI infrastructure demand despite near-term volatility.
