Why the FTC Lost Its Bid to Unwind Meta's Instagram and WhatsApp Deals

In April 2012, Facebook agreed to buy Instagram, a photo-sharing app with about a dozen employees and no revenue, for $1 billion. People laughed at the price. Two years later, Facebook agreed to buy WhatsApp, the messaging service, for about $19 billion, and fewer people laughed. The Federal Trade Commission looked at the Instagram deal at the time and let it close without a challenge. Eight years after that, the same agency went to court arguing the deals had been part of an illegal strategy to buy up threats before they could grow. The case went to trial in April 2025, with Mark Zuckerberg on the witness stand explaining emails he had written more than a decade earlier. In November 2025, Judge James Boasberg of the federal district court in Washington ruled for Meta. The lesson of that loss is not what most people assume.

In short: Judge James Boasberg ruled in November 2025 that the FTC had failed to prove Meta currently holds monopoly power, mainly because he found the relevant market includes TikTok and YouTube. The FTC's evidence about why Meta bought Instagram and WhatsApp was strong; its case foundered on how to define the market today. The ruling shows how hard it is to undo a merger years later, and why merger review at the time of the deal matters most.

The deals and the emails

The FTC's case rested on a simple story with good documents behind it.

In the early 2010s, people were moving from desktop computers to phones, and Facebook was not built for phones. New apps, designed mobile-first, were growing fast. Instagram was one of the most important. Internal emails showed that Zuckerberg saw Instagram as a potential threat and considered buying it a way to neutralize a competitor rather than face it. In a 2008 message, years before either deal, he had written that it was better to buy than to compete. The FTC presented these documents as the clearest possible statement of intent.

WhatsApp fit the same pattern. It was a messaging service with a huge international user base, and the FTC argued that Facebook feared it might add social networking features and become a rival. Buying it removed that possibility.

The agency's theory was that this was a buy-or-bury strategy: acquire the promising rivals and use control of Facebook's platform to cut off those that would not sell. That is monopoly maintenance under Section 2 of the Sherman Act, the same legal framework used against Microsoft in the 1990s.

A case that almost ended before it started

The FTC first filed the suit in December 2020, during Donald Trump's first term, after a long investigation. A coalition of states filed a parallel case. In June 2021 Judge Boasberg dismissed the FTC's complaint because it had not adequately alleged that Facebook had monopoly power. The complaint asserted that Facebook held more than 60 percent of a market for personal social networking, but the judge said the agency had not explained how it measured that share. He dismissed the states' case for a different reason: they had waited too long to challenge deals completed years before.

The FTC, by then led by Lina Khan, filed an amended complaint in August 2021 with more detail on how it measured the market. The judge let that version go forward. After years of discovery, the trial ran from April into late May 2025, under an FTC now led by a Republican chairman, Andrew Ferguson, who chose to continue the case.

That history is worth noticing. Like the Google search case, this was a bipartisan prosecution, started under one administration, carried by a second and tried by a third.

The trial itself was unusually personal. Zuckerberg spent parts of several days on the stand, walking through messages he had written as a young chief executive worried about losing the shift to mobile. Former executives from Instagram and other parts of the company testified too. For a few weeks, the internal history of the social media era was laid out in a federal courtroom in Washington, document by document, in a way that no investigative report had managed.

How Meta won: the market

Every monopoly case turns on the market. You cannot have a monopoly over nothing in particular; you have to have it over something defined. The FTC defined the market as personal social networking services, apps people use mainly to share with friends and family. In that market, the agency argued, the main players were Facebook, Instagram and Snapchat, with MeWe as a minor one. Under that definition, Meta was dominant.

Meta argued that the market was much larger. People spend their time on TikTok, YouTube, iMessage, X and other services, and those apps compete directly with Facebook and Instagram for attention and for advertisers. Meta's evidence showed that when TikTok surged, people shifted time away from Instagram and Facebook, and Meta responded by copying TikTok's short-video format with Reels. That, Meta argued, is what competition looks like.

Judge Boasberg agreed with Meta on the decisive point. He found that the apps had changed over time, that Facebook and Instagram now devote much of their feeds to content from people users do not know, chosen by algorithms, and that in this respect they look a lot like TikTok and YouTube. With those services in the market, the FTC could not show that Meta currently had monopoly power. And because the agency was seeking an order to break up the company now, it had to show a present monopoly, not one that existed in the past.

In other words, the FTC may have had the better story about 2012. It lost the argument about 2025.

The strongest case for the FTC

It is worth spelling out why many antitrust scholars think the decision got something important wrong.

First, the change in Meta's products is partly a result of the conduct in question. If Meta had faced a serious independent Instagram, the market for sharing with friends might look very different today. Courts usually judge market power in the present, but when the monopolist's own acquisitions shaped the present, that rule can reward the very conduct the law forbids.

Second, attention competition can be a trap for market definition. Almost everything competes for attention: television, books, sleep. If antitrust law defines markets by what people do with their time instead of by what products serve the same specific need, it becomes hard to find any monopoly in consumer tech at all. The distinctive thing about Facebook and Instagram, critics argue, is the network of real friends and family. TikTok, which is built around strangers and creators, does not substitute for that.

Third, the evidence of intent was unusually clear. The law does not punish intent alone, but documents in which a chief executive describes buying a competitor to neutralize it are exactly what Congress had in mind when it wrote merger and monopoly law.

The strongest case for the judge

The other side deserves equal care.

First, the facts on the ground did change. Short video is now the center of social media. TikTok's rise, and Meta's scramble to respond, look like real competitive pressure. If a firm with monopoly power can be forced into costly imitation by a newcomer, it is fair to ask how much monopoly power it has.

Second, the remedy the FTC wanted was drastic. Undoing a merger more than a decade later means separating products whose systems, staff and users have been woven together for years. Courts are right to require strong proof before ordering that, and the burden is on the government.

Third, the FTC's 2012 decision to let the Instagram deal close matters. Businesses need to be able to rely on regulators' decisions. If an agency can clear a deal and then challenge it eight years later, every merger carries open-ended risk. The judge did not decide the case on that basis, but the concern hung over it.

I find the first set of arguments more persuasive, because they go to what antitrust law is for. But it is fair to say that this was a hard case, and that the FTC's choice of market definition left it exposed.

What the loss really teaches

The headline lesson people draw is that Big Tech cannot be beaten in court. That is too broad. The government won against Google in search and in ad tech. The more precise lesson is about timing.

Merger law is designed to stop deals before they happen. Section 7 of the Clayton Act lets regulators block a merger whose effect may be to substantially lessen competition, a forward-looking standard that does not require proof of an existing monopoly. When the government waits years and then tries to unwind a deal under Section 2, it has to prove much more: a monopoly that exists today and conduct that maintained it.

That is why the real failure in this story came in 2012, not 2025. A small agency, reviewing a $1 billion purchase of a company with no revenue, did not see the threat that internal emails made obvious in hindsight. The fix is to give merger reviewers the tools, information and staff to evaluate acquisitions of young companies by dominant platforms, including deals that fall below the size that requires advance notice. Updated merger guidelines in 2023 tried to address this, and bills in Congress have proposed stricter rules for acquisitions by the largest platforms.

It is also a reminder that the stakes are human. The fight is not really about whether Mark Zuckerberg keeps two apps. It is about whether people who want a social network built differently, with better privacy or less addictive design, ever get the chance to choose one, and whether small businesses that advertise to reach customers have any alternative.

How courts draw a market, in plain terms

The whole case turned on a question that sounds technical but is really about common sense: what else could people switch to?

Antitrust courts usually approach market definition with a thought experiment. Imagine a single company owned every product in a proposed market. Could it profitably make things a little worse for customers, by raising prices, cutting quality or, in the case of free apps, showing more ads or collecting more data, without losing so many customers to products outside the market that the move backfired? If it could, the market is real. If customers would flee to something else, that something else belongs in the market too.

Free products make the test hard to apply. Facebook and Instagram do not charge users. The FTC argued that degraded privacy and more ads are the price users pay, and that Meta had been able to impose that price precisely because people had nowhere comparable to go for keeping up with friends and family. Meta argued that users show, every day, that they move their time to TikTok and YouTube when those apps are more appealing, and that advertisers move their budgets the same way.

The judge's answer leaned on how people actually use the apps now. Whatever Facebook was in 2012, he found, much of what users see on it and on Instagram today is recommended video and posts from accounts they do not follow, which is exactly what TikTok and YouTube offer. Critics reply that the test should ask what users would do if the friends-and-family part of the product got worse, not what they do with the entertainment part. That disagreement is the case in miniature.

What happened to Instagram and WhatsApp after the deals

There is a human story inside the legal one. The founders of both companies stayed on after the acquisitions, and promises were made about independence. Both sets of founders eventually left.

WhatsApp's co-founders had built the service around privacy and a dislike of advertising. Brian Acton left in 2017 and later helped create the Signal Foundation, which supports the encrypted messaging app Signal. Jan Koum left the following year. Instagram's co-founders, Kevin Systrom and Mike Krieger, left in 2018. Reporting at the time described tensions with Facebook's leadership over how independent the products would remain.

Defenders of the deals point out that Meta invested heavily in both services, that Instagram and WhatsApp grew to serve billions of people, and that they might never have reached that scale alone. Critics answer that we cannot know what an independent Instagram or WhatsApp would have become, and that this is the point: the acquisitions removed the possibility of finding out. The counterfactual cannot be proved either way. That uncertainty is exactly why merger law asks regulators to act before a deal closes, when the competing paths are still open.

What you can do

The next Instagram is being built somewhere right now. Whether it gets bought before it can compete depends on merger enforcement. Some steps:

1. Push for stronger merger review of dominant platforms. Use the representatives finder to reach your House member and senators, who set the FTC's budget and write the merger laws.
2. Watch for rules and guidelines open to public input. Agencies seek comment on merger guidance and filing rules; our comment tracker lists federal rules open now, closing soonest first, with tips on writing a useful comment.
