Meta led its megacap peers as Muse drew early consumer interest. CNBC links investor optimism to the AI app’s momentum.
Listen to this story
Investors rewarded Meta’s consumer-AI push during September, with the stock gaining 27% and closing at $725.18 as attention centered on its Muse app. CNBC linked the rally to Muse’s early traction, including an iOS download lead over ChatGPT, but that ranking does not establish revenue, retention, or how much the app drove the shares. The market response is clear; Muse’s durable business value is not yet demonstrated.
Muse debuted September 8; CNBC reported it surpassed ChatGPT in Apple iOS downloads, a platform-specific milestone.
Meta outperformed all megacap peers while the Nasdaq gained almost 2%, underscoring the scale of the move.
September was Meta’s fifth-best month on record and its strongest since November 2022, when shares rebounded amid the company’s efficiency push.
Meta ended September 30, 2026, at $725.18 a share, up 27% for the month. Its strongest monthly gain since November 2022 came as CNBC described investor enthusiasm for Muse, the company’s new personal AI agent app.
The shares had closed August at $572.34. September’s advance put Meta ahead of all its megacap peers—the other largest publicly traded companies—according to CNBC. The rally stood out even in a rising market.
Meta’s September gain measured against its closing share price at the end of August.
The Nasdaq gained almost 2% during September, according to CNBC.
September was also Meta’s fifth-best month on record, according to CNBC. The last larger monthly advance came in November 2022, when Meta was rebounding near the end of a brutal year and beginning its efficiency push. OpenAI launched ChatGPT that same month.
The historical comparison spans two different settings: a recovery for Meta in 2022 and reported enthusiasm around its own consumer AI app in 2026. The company’s latest standout month follows the September 8 debut of Muse.
CNBC reports that Muse surpassed OpenAI’s ChatGPT in Apple iOS downloads and links Wall Street’s optimism to that early momentum. That gives the AI enthusiasm a concrete consumer milestone: Meta’s app drew enough download activity to overtake a prominent rival on one mobile platform.
Muse’s download lead describes early interest on one mobile platform; it is not a comparison of the two apps’ revenue or lasting use. Nor does the timing isolate how much of Meta’s rally came from Muse. The stock result is clear; the app’s durable commercial value remains unsettled.
