Micron’s third‑quarter earnings surged, posting a net income jump of nearly 1,400 % to $28.2 bn, topping Wall Street’s $24.3 bn estimate. The memory‑chip maker generated $41.5 bn in revenue, while its gross margin climbed to 84.9 %, a sharp rise from 39 % a year earlier in a tight market.

Investors cheered as Micron projected revenue of $50 bn for the current quarter, beating the $43.7 bn consensus. Shares leapt 14 % in after‑hours trade, snapping a 13 % slide earlier in the week that had stemmed from Fed‑rate fears and shifting risk‑free yields as the market digested data today.

The spike reflects a global AI infrastructure boom, with Nvidia and AMD demanding high‑bandwidth memory that Micron supplies. Four Big Tech firms plan to spend $725 bn on AI this year, pushing demand and enabling Micron to sustain margins above 80 % and pushing its stock higher.

Micron’s performance reaffirms its dominance in the memory‑chip market, where it shares a $1 tn+ valuation with SK Hynix and Samsung. The company’s robust margins and AI‑driven growth suggest that the supply bottleneck will persist, keeping investors focused on its next earnings cycle in a tightening cycle.
