Meta shares surge 11% to $741 after AI agent Muse tops US App Store
Meta Platforms shares climbed more than 11% to $741 on Sept. 21, 2026, adding about $190 billion in market value after its AI agent Muse reached No. 1 on the US App Store.
Meta Platforms shares climbed over 11% to $741 on Sept. 21, 2026, adding roughly $190 billion in market value. The stock crossed back over $700 earlier in the day for the first time since February 2026, capping an increase of more than 30% month-to-date off its summer lows. Reports diverged on historical benchmarks: Coin Bureau reported the surge as Meta's largest single-day gain since April 2025, whereas The Kobeissi Letter noted earlier that gains exceeding 10% put the stock on track for its best daily performance since July 2025.[1][3][4][5][6][7]
The rally followed positive investor sentiment toward Meta's new AI agent, Muse, which reached No. 1 on the US App Store. According to The Wall Street Journal, as cited by Coin Bureau, Muse's breakout provides investors with the clearest evidence yet that Meta's massive AI spending can translate into a consumer product.[3][8]
Meta's jump occurred alongside a broader rally across technology equities. The Nasdaq 100 rose more than 2%, while the S&P 500 gained 1.5% and added $1 trillion in market capitalization.[2][8]
