Background

Fastly (NYSE: FSLY) stock surged 16.2% in afternoon trading, staging a powerful intraday reversal after a social media post revealed the company's significant and previously underappreciated role in handling traffic for Meta's Muse AI assistant.

AI Traffic Revelation Sparks Rally

The primary catalyst for the rally was a post on the social media platform X from an account named Odd Diligence. The account published findings from a series of controlled tests, which reportedly showed that Fastly handles 29.3% of traffic for the Meta Muse AI assistant. This positioned Fastly as a key infrastructure provider in the high-growth AI space, a factor investors had not previously priced into the stock.

The news triggered a sharp reversal from early session losses, where the stock had dipped to $24.04 amid apparent profit-taking. Shares then rallied aggressively to a session high of $31.33 before settling near $30.31.

The revelation landed amid a wave of positive sentiment following Fastly's Investor Day in New York on September 22. Several analysts reiterated bullish outlooks, citing the company's strategic focus on artificial intelligence.

  • Evercore ISI reiterated an Outperform rating with a $32 price target, highlighting Fastly's new AI product suite for security and governance.
  • Raymond James also maintained its Outperform rating with a $29 price target.
  • A Seeking Alpha analyst raised their price target to $34, pointing to the company's long-term revenue framework of $1.1 billion to $1.3 billion by 2029.

Market Impact

Fastly's rally was entirely driven by company-specific news, occurring in defiance of a broader market downturn that saw the S&P 500 fall 0.7% and the Nasdaq Composite decline 1.1%. The bullish sentiment was further underscored by heavy options activity, with call volume running approximately 187% above its typical daily average, according to the source report. This indicates strong investor demand for bets on the stock's continued upside.
