900 million weekly active users. That is ChatGPT's current reach - over 10% of the global population - according to Andreessen Horowitz's latest Top 100 Gen AI Consumer Apps report, based on January 2026 data from SimilarWeb and Sensor Tower.
The gap between ChatGPT and everyone else remains enormous: 2.7x larger than #2 Gemini on web traffic, 2.5x larger on mobile. But the chasing pack is growing fast. Claude's paid subscribers grew 200% year-over-year. Gemini grew 258%. About 20% of ChatGPT's web users also use Gemini weekly, suggesting many power users are hedging across platforms.
Midjourney's Freefall
The most dramatic shift in the rankings: Midjourney dropped from the top 10 to #46. The culprit is obvious. ChatGPT and Gemini both shipped native image generation models that are good enough for most use cases. When image generation is built into the chatbot you already use, a standalone tool needs to be dramatically better to justify the extra subscription. Midjourney still produces excellent images, but "excellent" is losing to "good enough and already open in my browser."
The creative tools category is shifting more broadly. Image generation is losing ranking slots while video, music, and voice tools are gaining them. Suno held at #15 for music generation. ElevenLabs kept its position in voice. Chinese video models like Kling AI, Hailuo, and Pixverse are leading on quality, though Google's Veo 3 has closed the gap in the US market. OpenAI's Sora hit 1 million downloads faster than ChatGPT did, but fell below the monthly active user threshold for this edition - a flashy launch that did not convert to habit.
The $1 Billion Coding Tool
Claude Code reached a $1 billion annualized revenue run rate in just six months. That number sits alongside other signals that AI is escaping the chat window: Cursor, Replit, and Lovable are all showing sustained engagement in what a16z calls "vibe coding platforms." The agentic AI category is real and growing. OpenAI acquired OpenClaw (68,000 GitHub stars in weeks) in February. Meta bought Manus for roughly $2 billion in December 2025. Genspark announced $100 million in annual recurring revenue.
Meanwhile, embedded AI might be the bigger story. Notion's AI attach rate jumped from roughly 30% to over 50% in one year and now accounts for about half of Notion's revenue. CapCut has 736 million monthly active users. The AI meeting notetaker category - Fireflies, Fathom, Otter, TL;DV - hit 20 million combined monthly visits. These are not AI-native apps; they are existing products where AI became the core value proposition.
Three Internets, Not One
The report documents a geographic splintering that matters for anyone building or buying AI tools. Three distinct ecosystems are forming: Western tools (ChatGPT, Claude, Gemini, Perplexity) dominate the US, India, Brazil, and the UK. Chinese tools (DeepSeek, Doubao, Kimi) lead domestically with Western tools restricted by policy. Russia is building its own stack around Yandex Browser (71 million MAU) and GigaChat post-sanctions.
DeepSeek is the only tool bridging these divides: 33.5% of its traffic comes from China, 7.1% from Russia, 6.6% from the US.
One surprising data point: the US ranks just #20 in per-capita AI adoption. Singapore, UAE, Hong Kong, and South Korea all rank higher. America dominates in absolute numbers but not in how deeply AI has penetrated daily life relative to population.
a16z frames the competitive landscape not as a search-engine-style winner-take-all race but as something closer to the mobile OS wars - where two platforms with very different philosophies (ChatGPT's consumer-transaction focus vs. Claude's professional-tools focus) could both build massive businesses. Given that only 41 apps (11%) overlap between ChatGPT's and Claude's integration directories, that framing looks right.
