Micron Technology Inc., the largest US producer of computer memory chips, issued a quarterly sales forecast that surpassed Wall Street expectations on June 24, 2026, citing strong AI-driven demand [1, 2, 3, 4, 5, 6]. Following the announcement after market close, Micron shares jumped between 13% and 15% [1, 2, 3, 4, 6].
This upbeat forecast rekindled investor confidence in the artificial intelligence trade, driving gains across US and Asian stock futures and indices [1, 2, 3, 4, 5, 7, 8, 6]. Nasdaq 100 futures rose about 1.5% to 2%, and S&P 500 futures gained 0.5% to 0.7%, aligning with actual US market closes where the S&P 500 rose 0.63% and Nasdaq Composite rose 0.97% on June 25 [1, 3, 4, 9, 6, 10].
South Korea's Kospi index surged as much as 6%, bolstered by gains in chipmakers Samsung Electronics and SK Hynix, which seeks to capitalize on growing memory chip demand by announcing plans for a US public listing targeting about $29 billion [1, 3, 4, 5, 8, 6].
Financial analysts highlighted the significance of Micron's performance. Kyle Rodda of Capital.com said, "Micron far exceeded analyst expectations and, crucially, forecast robust future chip demand. US futures have more than recovered the losses sustained in cash trade, positioning Asian markets for a much more positive session" [4]. Chris Strazzeri from Moomoo Australia and New Zealand noted that investors are now demanding profits to justify valuations, with Micron "boosting tech sentiment overall" [8]. Rick Gardner from RGA Investments advised investors to consider opportunities presented by market pullbacks, calling the tech sector "still fundamentally strong" [2]. Mark Hackett of Nationwide cautioned that "when stocks rise too much and too fast, a pullback almost always ensues" [2].
European shares also advanced modestly, driven by technology stocks as strong forecasts from Micron and Qualcomm renewed enthusiasm for AI-related equities [11]. Meanwhile, Brent crude oil prices dipped below $74 per barrel amid easing US-Iran tensions and easing supply concerns, which helped push bond yields lower and further improved market sentiment [1, 2, 3, 4, 8, 6, 11].
On June 25, 2026, Wall Street's major indexes opened higher, with the Dow Jones Industrial Average up 0.31%, the S&P 500 rising to 7,404.91, and the Nasdaq Composite closing at 25,724.78, all supported by Micron's strong outlook and positive economic data [9, 10].
