Meta Climbs on Its Muse AI Agent as the Broader Market Falls

The stock rose as much as 7% in Wednesday trading, bucking a broad selloff, after Meta launched a consumer AI agent with paid subscription tiers that Wall Street read as the start of a new product cycle.

Meta stock climbed sharply in Wednesday trading, rising as much as 7.2% and holding up about 6.5% in early afternoon, even as the broader market fell. The move followed the company’s Tuesday-evening launch of Muse, a consumer artificial-intelligence agent that Meta bills as its first built for everyday users. The S&P 500 was down 0.4% and the Nasdaq off 0.6% at the same hour, with oil above $100 and Treasury yields near multi-year highs weighing on stocks. Among big technology names, Meta stood almost alone in the green. The launch drove it.

An agent that books the reservation

Meta describes Muse as a personal AI agent that acts on instructions rather than just answering questions. By the company’s account, it can send emails, schedule appointments, make online purchases, and book dinner reservations, working across Meta’s family of apps and connecting to outside services such as OpenTable and Ticketmaster. Meta also said it built a “Confidential Virtual Machine” to encrypt user data during those tasks, with the company stating that not even Meta can read it. That framing is Meta’s own. No independent test of it has been published.

The first bill to consumers

The launch came with a price list. Muse has a free tier, with paid plans at $20 and $100 a month depending on how heavily a user leans on it, according to reports from Motley Fool and 24/7 Wall St. That structure matters beyond the features. For years Meta has monetized its apps almost entirely through advertising, so a monthly subscription tied directly to AI is a new and separate revenue line. Several analysts framed the product as the opening of a fresh product cycle, one they say is not yet reflected in the share price.

Alphabet slips as the agent race reopens

The read-through hit a rival. Alphabet fell about 2% in the same session, with several outlets tying the decline to Muse’s move onto the consumer-agent territory Google has been building around Gemini. The worry is specific: if an agent that handles shopping and travel becomes a daily habit, it chips at the search queries that anchor Google’s advertising business. Alphabet faced other pressures Wednesday, including European antitrust headlines, so Muse was one weight among several.

The spending still has to pay off

The rally sits on a heavy bill. Meta has guided 2026 capital spending to between $130 billion and $145 billion, nearly double its 2025 outlay, and the strain shows in its cash flow. Free cash flow fell to $784 million in the most recent quarter from $8.55 billion a year earlier, according to filings summarized by Blockspace and 24/7 Wall St. A consumer subscription is the clearest path yet to charging directly for that build-out, though it has to scale to matter against numbers that large. One skeptical read of Wednesday’s move called it sentiment running ahead of evidence.

Meta separately said it had agreed to buy Stilla.ai, a Stockholm startup founded in 2024, to speed development of its Business Agent for commerce on WhatsApp, Messenger, and Instagram, according to Axios. The deal points at the same goal from the merchant side.

What to watch

The near-term signposts are simple. The first is Wednesday’s close, which will show how much of a gain this size survives a down day. Beyond that, the questions are adoption and price: how many users pay for an agent instead of staying on the free tier, and whether daily reliance on Muse actually forms. The competitive scoreboard now has two names on it. Whether Meta’s agent pulls attention from Google’s will take more than one session’s tape to judge.
