A long-awaited trial between Meta and the Federal Trade Commission kicks off on April 14th. Over about two months, DC District Court Judge James Boasberg will hear arguments about whether Facebook illegally monopolized the market for personal social networking services through its 2012 and 2014 acquisitions of Instagram and WhatsApp.

The FTC first brought the case in late 2020, and while it was initially thrown out by the judge, he let an amended version move forward because the government had beefed up details about why Meta is allegedly a monopoly. This phase of the trial will help the judge determine if Meta is liable for breaking antitrust laws. If he finds it is, he’ll later rule on how its harms should be remedies — including potentially by breaking it up.

The Meta trial is the third trial seeking to break up a tech monopoly in recent years, following the Justice Department’s two separate cases against Google over its search and ad tech businesses. CEO Mark Zuckerberg has personally lobbied President Donald Trump to try to avoid the trial.
