What happened
Micron (MU) stock rose 1.7% to $919.20 in premarket trading on Tuesday as Anthropic's IPO filing and a Bank of America call for tight memory supply through 2028 lifted AI chip demand hopes. SanDisk (SNDK) gained 1.1% to $1,268.38 and SK Hynix (SKHY) rose 2.7% to $146.43. Memory chips are scarce because AI data centers are buying huge amounts, which lets makers charge more. SanDisk is up about 432% this year and reports earnings Thursday. SK Hynix may announce a $12 billion special dividend (an extra cash payout) on Wednesday.
Why it matters
Micron's rally shows how much money is flowing to the chips that store data for AI. Memory is in short supply, so prices and profits for makers have jumped, and Bank of America expects the squeeze to last through 2028. The moves also show how fast these stocks swing: SanDisk is still about 46% below its 52-week high.
