BrightEdge: ChatGPT referral traffic share hits record 95.1%
ChatGPT’s referral traffic to websites rose 101% between January and August 2026, giving it a record 95.1% share of AI-platform referral traffic in August, per BrightEdge. Gemini held 2.4%, Perplexity 1.1% and Claude 0.8% — a combined 4.3% — meaning ChatGPT sent roughly 22 times as many referred visits as its three rivals combined. ChatGPT’s share had dipped to an 89.5% low in April before climbing back; BrightEdge’s release does not disclose how many sites, or how much traffic, underlies the measurement.
Why it matters: For anyone optimizing for AI search, a near-total ChatGPT share of AI referral traffic means most of the current AI-driven traffic opportunity runs through one platform rather than several — though BrightEdge does not disclose the methodology behind the measurement, so the size of that opportunity is unverified.
