Frontier firms (95th percentile of AI use) consume 3.5x more intelligence per worker than typical firms, up from 2x in April 2025: OpenAI B2B Signals
Message volume explains only 36% of the frontier advantage; the majority comes from deeper, more complex AI use: OpenAI B2B Signals

Conclusion
ChatGPT entered 2026 as the dominant AI platform by user count, but a more competitive one than it was in 2023. It crossed 900 million weekly active users and 1 billion monthly active app users in the same quarter. OpenAI hit a $25 billion annualized revenue run rate and filed for an IPO targeting a $1 trillion valuation.
At the same time, web-visit market share dropped from 77% to roughly 55%. Claude overtook ChatGPT in business AI spending for the first time. Meta AI reached 1 billion users. Gemini reached 750 million. The era of single-platform AI dominance is over.
For individuals, ChatGPT remains the default entry point into AI. For enterprise buyers, the purchasing decision now involves ChatGPT, Claude, and Gemini running side by side. Codex and GPT-5.5 represent OpenAI's clearest bet on locking in professional and developer workflows before competitors close the gap.
