Meta Connect 2026: How Muse AI Makes Zuckerberg's Keynote a Stock Catalyst

Meta Platforms stock (ISIN: US30303M1027) closed on September 22, 2026 on the Nasdaq at $741.25 and recorded a daily gain of 11.43 percent – the strongest increase since April 2025, as CNBC reported. Trading volume reached 48.72 million shares and significantly exceeded the usual level. During the trading session, the stock moved between $679.60 and $753.00.

Muse AI as primary price driver

Market observers cite strong market adoption of the new AI assistant Muse and rising expectations for Meta's AI business as triggers for the rally. The Muse agent – an AI assistant designed to function across Meta's entire device ecosystem – has already won partners according to reports, fueling revenue expectations among investors.

Compared to the broader market, Meta significantly outperformed: While Meta stock gained 11.43 percent, the Nasdaq Composite rose only 0.45 percent on the same trading day to 27,244.28 points. The closing price was $49.55 below the 52-week high of $790.80 and $220.99 above the 52-week low of $520.26.

Analysts raise price targets significantly

Investment bank Jefferies raised its Meta price target on September 22, 2026 from $710 to $875 and confirmed its buy recommendation. Cantor Fitzgerald followed on September 23 and raised its price target to $860, maintaining an "Overweight" rating.

The rally also had personal consequences: CEO Mark Zuckerberg's wealth increased by $25 billion from the stock movement in a single day.

Meta Connect 2026: Keynote today at 4 p.m. PT

The two-day developer conference Meta Connect 2026 begins today, September 23, 2026, in Menlo Park and runs through September 24. CEO Mark Zuckerberg's keynote is scheduled for 4 p.m. Pacific Time. Zuckerberg is expected to explain in detail how Muse functions across Meta's entire device ecosystem and highlight the early market penetration of the AI assistant.

Beyond Muse, the following topics are expected at the keynote:

• Meta's comprehensive AI product vision and technology roadmap
• Developments in AI technology
• AI glasses and possible new headsets
• Virtual reality and Meta Horizon
• XR ecosystem developments

Timing as strategic advantage

The announcement of Muse came strategically just before Meta Connect 2026, creating a natural catalyst setup for the stock. The event serves as a direct corporate catalyst for today's U.S. trading session, particularly in light of the stock movements already underway.

Analysts characterize the keynote as an opportunity for Zuckerberg to build on the momentum created and demonstrate Meta's broader product vision and technology roadmap. The Muse agent is being assessed as a potential new AI variable for Meta – an additional revenue stream alongside established advertising businesses.

Classification for investors in the DACH region

For retail investors in the German-speaking region who buy Meta shares through European trading platforms, yesterday's price jump represents a significant appreciation of their positions. Meta stock is traded in euros on German exchanges, with exchange rate fluctuations potentially having additional effects.

The new analyst price targets of $860 to $875 imply upside potential of around 16 to 18 percent compared to the closing price on September 22. However, these forecasts represent estimates from individual investment banks, not guaranteed expectations. Actual price development will largely depend on how well Muse establishes itself in the market and whether Meta can deliver on its revenue promises.

Tonight's keynote (Central European Time: 1 a.m.) will show whether Zuckerberg presents concrete figures on Muse's market penetration or whether expectations are primarily based on corporate communications.
