What happened

Shares of Meta Platforms (META -1.12%) -- the artist formerly known as Facebook -- tumbled 3.5% in Tuesday afternoon trading, as of 3:20 p.m. ET, after Reuters reported that Britain's Competition and Markets Authority (CMA) has ordered the company to divest itself of the popular GIF website Giphy.  

So what

Facebook (as it was still known at the time) bought Giphy last year in a deal valued at $400 million, giving itself and its users potentially exclusive access to the company's library of GIFs (short for the Graphics Interchange Format files used to post short, animated images on social media sites). To date, neither Facebook nor its Meta Platforms parent company have prevented users of rival social networks such as TikTok or Twitter from accessing Giphy GIFs on their own sites. But the CMA is concerned that Meta Platforms might make such a move in the future, arguing that "the tie-up between Facebook and Giphy has ... removed a potential challenger in the display advertising market."

Moreover, the CMA noted that it had ordered Facebook to postpone buying Giphy while it was examining the proposed deal -- an order that Facebook apparently ignored, resulting in a $70 million fine from the CMA.

Now what

The CMA now argues that "requiring Facebook to sell Giphy [protects] millions of social media users and [promotes] competition and innovation in digital advertising."

Meta Platforms obviously disagrees with this assessment, and is planning to appeal the CMA's decision. It has four weeks from today to do so. If Meta Platforms loses on appeal, it will become in essence a motivated seller, and might not be able to sell Giphy for as much as it paid to acquire it.

Selling Giphy would not, however, necessarily deprive Facebook users of access to Giphy. In the long run, with Giphy or without it, I suspect Meta will do just fine.
