Meta shares rose 11.34% on Muse adoption reports and Connect expectations

September 21 market move

Meta Platforms closed at $741.25 on September 21, 2026, up $75.50, or 11.34%, from an implied prior close of $665.75, according to Investing.com historical data. The shares traded from $679.60 to $753.00 and volume reached 48.72 million shares.

Meta was the largest individual contributor to both major equity indexes during the session. It added 18.89 points, or about 16.5%, to the S&P 500's 114.20-point advance and 145.34 points, or about 17.3%, to the Nasdaq 100's 838.18-point gain, according to WMTMT. Communication Services rose 3.56%, with Meta as its largest contributor.

The broad market also rose sharply, with the S&P 500 gaining 1.49% and the Nasdaq 100 gaining 2.83%. That backdrop means the available evidence does not isolate how much of Meta's 11.34% gain came from Muse-related news, the Wells Fargo action, Connect expectations or the wider market advance.

Muse adoption and analyst action

Wells Fargo analyst Ken Gawrelski raised Meta's price target to $796 from $640 and retained an Overweight rating. The firm cited recent model releases, early Muse traction and product momentum before Meta Connect, according to reporting on the note by Reuters via Boursorama.

Wells Fargo cited Sensor Tower estimates that U.S. Muse downloads reached a record 264,000 on September 19 and daily active users reached 448,000 on September 18. These figures are third-party estimates and are not Meta-reported or audited operating metrics.

Apptopia separately estimated that Muse received 2.8 million installs in its first 12 days. In a normalized iOS comparison covering the United States and Canada, Apptopia estimated 1.8 million Muse downloads and 1.3 million ChatGPT downloads over corresponding launch periods, as reported by TechCrunch. The comparison is method-sensitive because the products launched in different distribution environments and Meta can cross-promote Muse through Facebook, Instagram and WhatsApp.

The supported inference from the move is that investors assigned a higher probability to Meta producing a consumer AI product with visible distribution. The early usage data do not establish sustained retention, recurring engagement, completed-task rates, monetization or a return on Meta's AI spending.

Connect, access and spending questions

Meta launched Muse on September 8, 2026. Meta describes the product as a personal agent that can complete multi-step tasks through a dedicated virtual machine and browser, with access through its own app and WhatsApp, in its launch announcement.

Meta Connect is scheduled for September 23-24, with Mark Zuckerberg's keynote scheduled for September 23 at 4 p.m. Pacific time. Meta has identified AI, AI glasses and virtual reality as subject areas for the event on its Connect site. Investor attention will center on whether Meta supplies company-verified Muse data on usage, retention, task completion or revenue.

Amazon blocked Muse from shopping on Amazon.com. Amazon said Meta lacked authorization, Muse did not identify itself as an automated agent, and its handling of customer credentials raised privacy and security concerns, according to GeekWire. Meta presents Muse as secure and private; Amazon's claims have not been independently adjudicated, and the block does not establish a security breach. The restriction shows that Muse's capabilities can depend on third-party platform access.

Meta's latest reported quarter frames the capital-return question. Second-quarter revenue rose 28% to $60.80 billion, expenses rose 55% to $42.03 billion, and operating margin fell to 31% from 43%, according to Meta's investor relations release. Meta reported $31.08 billion of quarterly capital expenditure and maintained 2026 capital-expenditure guidance of $130 billion to $145 billion. Future Muse revenue, advertising gains and margin effects remain uncertain.
