⬤ ChatGPT crushed the competition in 2025, and the numbers tell the whole story. Fresh Similarweb data tracking quarterly visits across major generative AI platforms shows OpenAI's chatbot pulling in traffic that nobody else could touch—we're talking low teens billions in Q1 climbing to mid-to-high teens billions by Q4. That's not just growth, that's complete market dominance.
⬤ Here's the thing: no other platform came remotely close. ChatGPT's traffic stayed consistently in the multi-billion range every single quarter, showing users weren't just trying it out—they kept coming back. The steady climb from roughly 10-13 billion visits early in the year to 15-18 billion by year's end proves ChatGPT locked in as people's go-to AI tool. The gap between OpenAI and everyone else? Massive.
⬤ Gemini managed to grab second place, but it's still playing catch-up. Google's AI started 2025 under a billion visits and worked its way up to several billion by Q4—impressive growth, sure, but still nowhere near ChatGPT's numbers. DeepSeek hovered around the one billion mark before cooling off later in the year, while Grok, Character AI, Perplexity, and Claude barely moved the needle, showing small gains but staying well under the billion-visit threshold.
⬤ Why this matters: we're looking at a winner-takes-all situation in AI. When one platform captures the lion's share of traffic while everyone else fights over scraps, it shows where real user trust and adoption lives. ChatGPT isn't just leading—it's defining what mainstream GenAI usage looks like. The smaller players are still growing, which means there's room for innovation and niche appeal, but right now the GenAI landscape has one clear king, and the rest are still figuring out how to compete for attention in an increasingly crowded market.
