Background

Shares of Fastly Inc. (NYSE: FSLY) surged as much as 17% on Wednesday after a social media analysis indicated the company may play a larger role in handling traffic for Meta's Muse AI assistant than Wall Street had previously estimated.

The Catalyst

The stock's sharp move followed a post on the social media platform X from an account named "Odd Diligence," which detailed findings from a series of controlled tests. The analysis, which it said was based on 738 tests over the past week, tracked the infrastructure providers used by Meta's Muse AI for various requests.

The data suggested a more balanced distribution of traffic than the market may have priced in:

  • Cloudflare (NET): 37.0%
  • Fastly (FSLY): 29.3%
  • Meta (META): 19.4%
  • Amazon Web Services (AWS): 14.4%

Key Findings

The analysis highlighted a critical distinction in how traffic was routed based on the type of task. According to the post, Fastly was used in 100% of tests that required browser navigation, such as asking the AI to visit a restaurant's website to find a menu or to navigate a site to book an appointment.

In contrast, competitor Cloudflare was reportedly used for 100% of tests involving direct API or curl requests. Simpler web search queries were split among all four providers, the post stated.

Market Impact and Context

These findings are significant for investors because much of the prior analyst commentary regarding Meta's AI infrastructure partners had focused heavily on Cloudflare. The social media report suggests Fastly's involvement is more substantial and nuanced than was widely understood.

The potential for increased, high-value traffic from a major AI initiative like Meta's Muse could represent a material, previously unaccounted-for revenue driver for Fastly, prompting a swift repricing of the company's stock by the market.
