TikTok reaches roughly 131 million adults with ads in Brazil, Digital 2026 reports

The Digital 2026 Brazil report (DataReportal) sets the market's reference numbers: Brazil closed 2025 with roughly 185 million internet users (86.9% penetration), and TikTok's advertising reach among people aged 18 and over comes to approximately 131 million people — 80.3% of the adult population.

What this means for advertisers in Brazil: with eight in ten adults reachable, TikTok has stopped being a young-audience niche — it is mass media with performance targeting. Any plan still treating it as an “experiment” is under-allocating the channel with the highest incremental reach in the digital mix.
