The Short Version
This claim is false. The most recent 2026 data shows Google remains the dominant search engine among Gen Z, ranked most helpful at 85% compared to TikTok's 16%. Only 4% of Gen Z say they rely more on TikTok than Google for search — down 50% from 2024. While Gen Z increasingly uses social media collectively for discovery, no credible current evidence supports TikTok alone being the most used search engine among this generation.
