Meta’s acquisition of Instagram and WhatsApp did not create an illegal social media monopoly a federal judge ruled, a decision that solidifies the future of the $1.5 trillion tech giant.

Judge James Boasberg in Washington, D.C., rejected the Federal Trade Commission’s claim that Facebook’s parent company monopolized the “personal social networking” market for connecting with friends and family.

“As it has forecast in prior Opinions over the years, the FTC has an uphill battle to establish the contours of any separate PSN market and Defendant’s monopoly therein,” Boasberg wrote. “The Court ultimately concludes that the agency has not carried its burden: Meta holds no monopoly in the relevant market.”

The ruling is the latest blow to the government’s effort to challenge Big Tech companies’ dominance over the internet after another federal judge in September refused to break up Google for monopolizing the online search market.
