Stock Market Today, Sept. 9: Meta Surges Over 6.5% on Muse AI Agent Launch
Today, Sept. 9, 2026, investors are watching whether the autonomous agent can unlock a new revenue stream for the social platform.
Overview
Social media and digital advertising giant, Meta Platforms (NASDAQ:META), closed at $653.69, up 6.55% on Wednesday. Meta surged after launching Muse, its personal artificial intelligence (AI) agent. The autonomous product, which can shop online, book flights, and organize calendars, could be key to monetization for the firm.
Trading volume reached 35.2 million shares, coming in about 98% above its three-month average of 17.8 million shares. Meta Platforms IPO'd in 2012 and has grown 1,455% since going public.
The S&P 500 (SNPINDEX:^GSPC) fell 0.48% to 7,636, while the Nasdaq Composite (NASDAQINDEX:^IXIC) fell 0.64% to 26,253. Among social media peers, Alphabet closed at $330.65, down 2.28%, and Snap closed at $5.31, down 2.21%, showing softer sentiment across digital-ad names even as Meta moved higher.
Details
Meta's Muse launch marks a significant shift in narrative for the tech giant, which has struggled this year as concerns about its high AI spending and a social media addiction trial weighed on the stock. Now, not only is the legal case settled, but Muse also gives some reassurance that Meta’s capex investments will bear fruit.
