AI server optimism lifts September 21, 2026 in numbers
Super Micro Computer Inc. (ISIN US86800U1043, Nasdaq: SMCI) opened the regular session near USD 40 and climbed to an intraday high of USD 41.48 before settling at USD 41.30, noticeably above the midpoint of its 52-week range between USD 23.42 and USD 42.39. Per Nasdaq data cited by a report on MEXC, today’s move represented a 5.76 percent gain versus the prior close of USD 39.09.
As Investing.com reported, Super Micro’s advance came as AI server hardware names rallied on a recent Goldman Sachs research view that the global AI server market could grow aggressively toward roughly 1.5 trillion U.S. dollars by 2030, with AI-specific servers making up most of that total. In mid-session commentary, Yahoo Finance highlighted SMCI as a trending name, noting the stock’s roughly 4.9 percent rise earlier in the day and its outperformance versus the broader market.
