Meta Platforms Inc. (META) just scored a decisive courtroom victory, with a federal judge officially rejecting government claims that Facebook's parent company runs an illegal monopoly in social networking.

The ruling handed down Tuesday ends a seven-month trial where regulators tried to break up the tech giant by forcing it to unload WhatsApp and Instagram. Spoiler alert: they didn't succeed.

The Social Media Landscape Has Changed

Judge James Boasberg based his decision largely on how dramatically the online world has shifted in recent years. Video platforms like YouTube and TikTok aren't just hanging around the periphery anymore—they're direct competitors eating into Meta's user base.

According to the court, consumers are actively choosing these alternatives, which forces Meta to spend aggressively just to stay in the game. That's not exactly monopoly behavior.

"While each of Meta's empirical showings can be quibbled with, they all tell a consistent story: people treat TikTok and YouTube as substitutes for Facebook and Instagram, and the amount of competitive overlap is economically important," Boasberg wrote.

He didn't stop there. "Against that unmistakable pattern, the FTC offers no empirical evidence of substitution whatsoever," he added.

What the Court Actually Said

The District Court in Washington, D.C., determined that the Federal Trade Commission simply couldn't prove its case. Sure, maybe Meta had market dominance at some point in the past. But right now? The evidence doesn't support it.

"Whether or not Meta enjoyed monopoly power in the past, though, the agency must show that it continues to hold such power now," Boasberg explained in the filing. "The Court's verdict today determines that the FTC has not done so. A judgment so stating shall issue this day."

Five Years in the Making

This lawsuit has been grinding through the courts since 2019. Regulators wanted to force Meta to sell off WhatsApp (purchased in 2014) and Instagram (bought in 2012), arguing those acquisitions eliminated consumer choice and crushed competition.

The legal journey had its twists. Boasberg initially dismissed the complaint back in 2021, citing insufficient evidence of "market power." But the FTC came back with an amended version loaded with data comparing Meta to defunct platforms like Google+ and Myspace. That got them to trial, which featured testimony from CEO Mark Zuckerberg and former COO Sheryl Sandberg.

Meta's Victory Lap

Following Tuesday's ruling, Meta released a statement that was equal parts celebration and diplomatic outreach.

"The Court's decision today recognizes that Meta faces fierce competition," the company said. "Our products are beneficial for people and businesses and exemplify American innovation and economic growth. We look forward to continuing to partner with the Administration and to invest in America."

META Price Action: Meta Platforms shares were up 0.12% at $602.71 at the time of publication on Tuesday.
