In its lawsuit with the US, TikTok says in the US it had 11.3M MAUs in January 2018, 91.9M in June 2020, and now has 100M+; globally it had ~700M MAUs in July

Context & Ripple Effects
TikTok's court filing against the US government turns its own growth curve into legal evidence: 11.3M US monthly users in January 2018, 91.9M by June 2020, and 100M+ at the time of the suit, against roughly 700M globally as of July. The filing makes user scale the yardstick of the ban debate — the same numbers TikTok would go on to repeat publicly, hitting 100M MAUs in Europe within a month of the US milestone and reaching 1B MAUs globally by September 2021.
The disclosure also set a template TikTok kept using: when CEO Shou Zi Chew faced Congress in March 2023, the company again led with audience size, confirming 150M US MAUs, up from the 100M cited in this lawsuit — evidence that the court-filing figures became the baseline every subsequent defense was measured against.
First-order effects
- US policymakers weighing a ban now have TikTok's own sworn numbers on record, making 100M+ American users the official stake rather than an outside estimate.
- Advertisers gain a litigation-backed audience figure to plan against, which TikTok soon reinforced with its own pitch decks citing 732M global MAUs and a 59%-under-24 skew.
Second-order effects
- Meta's position sharpens: the filing's context — including the claim that 'policy makers only care about TikTok because Zuckerberg told them to' — frames the ban fight as partly a competitive dispute between the two apps, pressuring Facebook to argue on product rather than lobbying grounds.
- Each disclosed milestone raises the bar for the next one, pushing TikTok to keep publishing growth proof (Europe, then 1B global) to sustain advertiser confidence while under legal threat.
Third-order effects
- User-count disclosures are hardening into standard ammunition in platform-regulation fights, where a service's domestic audience size effectively determines how much political force a ban attempt carries.
- If the pattern holds, growth metrics will keep doing double duty as both marketing assets and legal exhibits, tying TikTok's commercial valuation directly to the outcome of national-security reviews.
The trend: TikTok is converting its user-growth milestones into standing legal and political defenses, making audience scale the central fact in the US ban debate.
