Meta booked $200.97 billion in 2025 revenue, up 22% year over year. Then a federal judge ruled it is not a monopoly. The FTC’s Meta monopoly ruling did not just end a lawsuit. It put a legal stamp on a claim every media planner already budgets around: TikTok and YouTube compete for the same ad dollars.
What the court actually decided
Let’s be precise, because the headline version gets mangled. On November 18, 2025, Chief Judge James Boasberg concluded that the FTC had failed to prove that Meta unlawfully monopolized “personal social networking” through its Instagram (2012) and WhatsApp (2014) acquisitions. The case ran nearly five years.
The market definition drove the outcome. The FTC wanted a narrow market of Facebook, Instagram, Snapchat and MeWe. The court disagreed and held that the relevant market should include TikTok and YouTube. Its reasoning was “convergence”: the judge found that Facebook, Instagram, TikTok and YouTube have evolved to have nearly identical main features, per the Skadden analysis.
That is a legal finding about user behavior, not an ad-buying study. Still, it lines up with how performance teams already work. Short video, creator feeds, and algorithmic discovery look similar across all four apps, and so do the budget lines that fund them.
The court’s market definition is the part to remember. When a judge says TikTok and YouTube can discipline Meta’s pricing, your media plan has a legal precedent for treating them as substitutes.
Is the case really over?
No. The FTC has filed an appeal, so treat the ruling as a strong signal rather than settled law. A reversal on appeal is possible, and a remand would take years. Nobody should rebuild a media plan around a coin flip on the outcome.
What can you plan around? The operating conditions that exist right now. There is no breakup of Instagram or WhatsApp on the horizon, no forced separation of Meta’s ad stack, and no court-ordered change to how Meta sells inventory. For brand teams, that is continuity, and continuity has a price.
Meta’s ad machine keeps compounding
Look at what Meta reported for the full year. Ad impressions rose 12% and average price per ad rose 9% for full-year 2025. Read that carefully. Meta is serving more ads and charging more per ad at the same time.
The trend has continued. In its quarterly filing, Meta reported $64,601 million in revenue for the three months ended September 30, 2026, against $51,242 million in the same quarter a year earlier. Scale like that is exactly what the FTC argued amounted to monopoly power, and the court did not buy it.
So what does rising price per ad mean for you? Some of it reflects better targeting and AI-driven delivery. Some of it reflects auction pressure. We covered the second factor in our piece on how Meta AI brings SMBs into the auction. More small advertisers means more bidders, and enterprise brands share that auction whether they like it or not.
Where the competing dollars go next
With the court treating YouTube and TikTok as real alternatives, the question for CMOs becomes practical. Which platform earns the next incremental dollar? Three shifts are worth watching.
- Search behavior on short-video apps. Gen Z increasingly starts product discovery on TikTok. Our analysis of TikTok versus Google for Gen Z shows why brands must prove lift rather than assume it.
- Creator-led placements. Paid and organic creator content now competes with standard ad units for the same budget. That is why premium TikTok placements need their own proof of return.
- Funnel friction. When platforms change link and conversion mechanics, cost per acquisition moves. See how TikTok’s bio link change forced funnel rebuilds.
Notice the pattern. None of these shifts depends on antitrust. They are already happening. The ruling simply removes the argument that Meta sits in a separate market where nobody can compete with it.
What brands should do now
Here is the operational playbook I would hand a head of paid social or an agency lead.
- Stop budgeting by platform silo. Build a single short-video and social video pool across Reels, TikTok, and YouTube Shorts. Set the split by incremental return, not by last year’s allocation.
- Run holdout tests on the Meta share. If Meta’s price per ad is climbing, verify that results are climbing too. A geo holdout or conversion lift study on a slice of spend will tell you.
- Negotiate with the substitute in the room. Agencies buying through managed-service deals should cite credible cross-platform alternatives when pricing and commitments come up.
- Keep creators portable. Contracts that let you reuse and repost creator content across platforms give you flexibility. Usage rights and whitelisting terms matter more than ever. Our guide on renegotiating creator terms covers what to ask for.
- Audit measurement before you shift. Moving dollars with unreliable attribution is just moving risk. A five-layer measurement audit is a sensible first step.
The creator angle most teams miss
Antitrust coverage tends to focus on platforms. Brand teams should focus on creators, because creators are the portable asset in a converged market. A creator with a strong audience on Instagram and a growing one on TikTok or YouTube lets you hedge platform pricing without rebuilding trust from scratch.
That favors brands that vet for audience fit rather than reach on a single app. It also means paying attention to niche expertise. If a platform’s costs rise, a smaller specialist with a loyal audience can deliver the same outcome at a lower cost per result. We have seen this in work on niche experts and affluent buyers.
One caution on compliance. More cross-platform posting means more disclosure surfaces, and each platform has its own labeling tools. A multi-platform plan needs one disclosure standard applied everywhere.
What this ruling does not tell you
It does not say Meta’s ads perform better or worse than anyone else’s. It does not rank platforms by return. It does not predict ad prices. Those answers sit in your own data.
It also does not mean regulators have lost interest in Big Tech. Skadden notes that the decision stresses forward-looking evidence in future antitrust cases, which cuts both ways for dominant platforms. And I could not verify current market share figures for TikTok and YouTube ad revenue from the sources I opened, so I have left them out rather than guess.
FAQs
Did the FTC win its monopoly case against Meta?
No. The district court found that the FTC failed to prove Meta unlawfully monopolized personal social networking. The FTC has appealed, so the final outcome is not settled.
Why does the ruling matter for advertisers?
The court defined the relevant market to include TikTok and YouTube alongside Facebook and Instagram. That supports treating the platforms as substitutes when you allocate budget and negotiate pricing.
Will Instagram and WhatsApp be separated from Meta?
Not under the current ruling. The FTC had sought divestiture or restructuring, but the court dismissed the case. Only a successful appeal would reopen that possibility.
Should brands move budget away from Meta?
Not because of the ruling alone. Move budget when incrementality tests show another platform delivers better return. Meta’s average price per ad rose 9% for full-year 2025, so test whether your results kept pace.
How does the ruling affect influencer marketing programs?
It strengthens the case for platform-flexible creator programs. Negotiate usage rights across platforms, vet creators for audience strength beyond one app, and apply one disclosure standard everywhere.
What should agencies tell clients right now?
Tell them the ruling confirms competition, not a change in how Meta sells ads. Recommend a cross-platform short-video budget pool, a holdout test on Meta spend, and a measurement audit before any large reallocation.
Your next step: pick one Meta campaign this quarter, run a conversion lift or geo holdout test on it, and compare the result with an equal-sized TikTok or YouTube test before you set next quarter’s split.
