Meta Stock Jumps as New AI Assistant Gains Millions of Users

Meta Platforms surged 11.34% on Monday, September 21, its largest single-day gain in more than a year, after its new personal AI assistant, Muse, rocketed to the top of Apple's U.S. App Store just 13 days after launch. The stock kept climbing into Meta's Connect 2026 developer conference on September 23 and 24, closing at a fresh 52-week high of $779.82 on Thursday, its highest level in about seven months, before slipping 3.33% on Friday after a New Mexico jury found the company misled Facebook users over data safety rules. Across the month, Meta shares are up roughly 36%, their best monthly performance since July 2013, and the company is closing in on a $2 trillion market capitalization. This piece covers what Muse actually is and how fast it grew, why the stock reacted the way it did, where the chart stands after breaking a year-long high, and how bulls and bears are weighing a rally built on early download numbers against a business still spending tens of billions of dollars a quarter to support it.

 

 

 

Muse launched in the United States on September 8, 2026, as a standalone personal AI agent, distinct from the existing Meta AI assistant embedded across Facebook, Instagram, and WhatsApp. Built on a model family Meta calls Muse Spark, Muse can find information across a user's accounts, fill out web forms, and negotiate and complete online purchases, going beyond simple question-answering into transactional tasks. Most capabilities are free, with power users able to subscribe to $20 or $100 monthly tiers for expanded functionality. According to Sensor Tower data cited by Invezz, Muse overtook ChatGPT as the leading free iOS app in the United States and recorded 730,000 downloads in roughly five days following launch; by the following Monday, downloads had surpassed 2.5 million, ahead of Anthropic's Claude and xAI's Grok on the same chart, and one Motley Fool analysis using different data put cumulative downloads at over 2.5 million after 12 days, compared with 3.1 million for ChatGPT during a comparable early window after its own launch.

The announcement cadence accelerated at Meta Connect 2026, held September 23 and 24 in Menlo Park, where CEO Mark Zuckerberg delivered the keynote. Meta confirmed new camera-free VR glasses priced at $1,299 and weighing roughly 100 grams, slated for a spring 2027 launch, alongside new audio glasses starting at $349 and a smaller Muse Charm device planned to ship for the 2026 holidays. Muse will also work hands-free on new smart glasses built with Ray-Ban and Oakley. Meta separately disclosed partnerships extending Muse's commerce capabilities with Instacart-owner Maplebear and travel company Expedia. On the financial side, Meta's most recent quarterly disclosures showed 28% revenue growth to $60.8 billion, with the company's family of apps reaching roughly 3.6 billion daily users, though operating margin slipped to 38.1% as AI infrastructure spending increased.

 

Meta shares had been under pressure for more than a year before this rally, falling from about $738 at the end of June 2025 to roughly $563 by June 30, 2026, a 24% decline, even as Wall Street analysts kept raising their price targets rather than chasing the stock lower. TIKR counted zero analysts moving to a sell rating throughout that stretch, and the mean target actually climbed as high as $867 in September 2025 before easing to $827 by mid-2026. That gap between where the stock traded and where analysts thought it should trade had persisted because investors were waiting for tangible proof that Meta's AI spending, guided to $130 billion to $145 billion for 2026, could translate into a product people would actually use.

Muse's download numbers provided that proof. On Monday, September 21, Wells Fargo analyst Ken Gawrelski raised his price target on Meta from $640 to $796 while maintaining an Overweight rating, citing Muse's rapid adoption as evidence the company "now has a story to tell" about its AI capabilities, a sharp reversal from a year earlier when Meta was dealing with delayed AI models and investor skepticism about its infrastructure spending. The stock responded by jumping 11.34% to close at $741.25 on volume of roughly 25.1 million shares, more than double its time-adjusted average, and traded as high as 12% intraday. Deepwater's Gene Munster highlighted the move as part of Meta's strongest month in years. By Thursday, September 24, shares had extended their advance to $779.82, a fresh 52-week high and Meta's highest close since early February 2026, when the stock last traded above $700, as Meta Connect added detail on hardware and commerce partnerships that broadened the case for Muse beyond a chatbot novelty. The stock remained below its all-time high close of roughly $786.80 from August 2025.

The rally has not been one-directional. Shares fell 3.33% to close at $751.66 on Friday, September 25, after a New Mexico jury found that Meta misled Facebook users over data safety rules, a reminder that litigation risk, including an earlier $2.4 billion legal charge, remains attached to the stock even during a period of strong sentiment. Analyst price targets kept climbing regardless: TipRanks logged fresh increases from Piper Sandler to $875, from Canaccord to $950, and from TD Cowen to $865 in the days following the verdict, while HSBC downgraded Twilio specifically citing pressure from the Muse-driven rally in adjacent software names.

 

 

 

Meta's rally has been unusually steep even by the standards of a mega-cap technology stock. Shares had fallen as low as the $520 range over the summer before climbing back above $700 in September for the first time since early February, when the stock last closed near $706, and by September 24 the shares had reached $779.82, a 52-week high but still about 0.9% below the stock's all-time closing high of roughly $786.80 from August 2025. The 52-week range now spans $520.26 to $779.82, a spread of more than $259, and the stock trades at roughly 21 times forward earnings, up sharply from a June low below 14 times, though still near its three-year average multiple according to Bloomberg data cited by Invezz.

Chart analysis published by TradingKey after Monday's breakout noted that the move decisively broke a downward trendline connecting prior candlestick highs, describing the pattern as a meaningful strengthening of bullish momentum with room to test $800 in the short term. Above that, the analysis pointed to the 0.618 Fibonacci extension near $880 as the next technical target if $800 holds, with a more ambitious path toward $1,000 if that level is cleared. On the downside, the same analysis flagged $700 to $710 as initial support, corresponding to the psychological level from before the breakout, with stronger support at $665 to $680 near the trading range that preceded the surge. Friday's pullback to $751.66 kept the stock well within the post-breakout range and did not test either support zone.

 

The bull case treats Muse's download numbers as the first real evidence that Meta's AI spending can generate a consumer product with mass appeal, not just an advertising-optimization tool. J.P. Morgan analysts, as cited by the Motley Fool, said they believe Muse has the potential to become the most widely used consumer AI application since ChatGPT, and noted that if Muse's download pace continues anywhere near ChatGPT's historic trajectory of 100 million users within two months, Meta could be building another billion-user app. Bulls also point to the monetization architecture already in place, with $20 and $100 monthly subscription tiers and direct commerce partnerships with Maplebear and Expedia giving Meta multiple paths to revenue beyond advertising, an argument that helped drive nine separate price target increases from firms including Piper Sandler, Canaccord, TD Cowen, and JPMorgan in the days following the Connect keynote.

The bear case starts with the fact that download counts are an early, easily gamed, and still partly unconfirmed metric. One analysis noted that reports of Muse reaching 2.8 million downloads in two weeks and topping U.S. and Canadian app store charts remained unconfirmed as of its writing, based only on third-party estimates rather than Meta's own disclosure. High download numbers also say nothing about retention or willingness to pay, and OpenAI's ChatGPT, despite passing 1 billion weekly users, is reportedly still unprofitable, a caution flag for assuming Muse's early success will translate cleanly into revenue. The financial backdrop adds pressure: Meta's free cash flow, which was $46 billion in the prior fiscal year, is projected by Bloomberg-compiled analyst estimates cited by Invezz to turn negative to the tune of $6.4 billion in 2026 and $29.2 billion in 2027 as capital expenditures climb toward $145 billion. Add an active legal overhang, underscored by Friday's New Mexico jury verdict, and the bear case is that Meta's stock has run 36% in a month on a product that is 16 days old.

 

The next hard checkpoint is Meta's third-quarter earnings report on October 28, where consensus EPS sits near $6.75. That report will be the first opportunity for Meta to disclose actual Muse engagement, retention, and subscription conversion data rather than third-party download estimates, and any gap between the App Store hype and Meta's own reported numbers could trigger a sharp repricing in either direction. Investors will also be watching capital expenditure guidance closely, since the $130 billion to $145 billion range for 2026 already implies a steep step-up in spending, and any further increase tied to Muse's infrastructure needs would pressure the negative free cash flow estimates further.

Litigation risk is a second, separate track running alongside the AI narrative. Friday's New Mexico verdict on data safety claims adds to an already elevated legal risk profile that includes a prior $2.4 billion charge, and further rulings or settlements could periodically interrupt the AI-driven rally regardless of how Muse performs commercially. With the stock trading at a fresh 52-week high and roughly 21 times forward earnings, above its June low but still near its multi-year average, traders may prefer to use the $700 to $710 support zone flagged by technical analysts, or the deeper $665 to $680 zone, as reference points for managing risk into the October 28 report.

 

Meta's September rally answers, at least provisionally, the question that had weighed on the stock for more than a year: whether the company's aggressive AI spending could produce something consumers actually want to use. Muse's early download numbers, a record-setting Connect keynote, and a wave of analyst price target increases have pushed the stock to a 52-week high and its best month since 2013, even as a legal setback and a genuinely negative free cash flow outlook complicate the picture. With $700 to $710 as the support zone that defined the pre-breakout range and $800 as the next resistance test, will Meta's October 28 earnings report confirm that Muse can convert its download numbers into durable revenue, or has the market gotten ahead of a 16-day-old product?

 

A: Meta rose 11.34% to close at $741.25 after Wells Fargo analyst Ken Gawrelski raised his price target from $640 to $796, citing rapid adoption of Meta's new Muse AI assistant, which reached number one on Apple's U.S. App Store 13 days after its September 8 launch.

A: Muse is Meta's standalone personal AI agent that can fill out forms, book tickets, and complete purchases on a user's behalf, accessible through a dedicated app or WhatsApp. Third-party data from Sensor Tower and other trackers put downloads at roughly 2.5 million to 2.8 million within about 12 to 16 days of its September 8 launch, though some of these figures remained unconfirmed by Meta itself.

A: Meta shares closed at a 52-week high of $779.82 on September 24, 2026, during the company's Connect developer conference, its highest level since early February 2026 but still below its all-time high close of roughly $786.80 from August 2025. The stock is up roughly 36% in September, its best monthly performance since July 2013.

A: Meta shares fell 3.33% to close at $751.66 after a New Mexico jury found that the company misled Facebook users over data safety rules, adding to existing litigation risk that includes an earlier $2.4 billion legal charge.

A: Meta guided 2026 capital expenditures to $130 billion to $145 billion, and Bloomberg-compiled analyst estimates cited by Invezz project negative free cash flow of $6.4 billion in 2026 and $29.2 billion in 2027, a sharp reversal from $46 billion in positive free cash flow the prior year. Meta's next earnings report, on October 28, 2026, should offer the first real data on Muse's monetization.
