The top 1% of AI users spend 36x the median

a16z's seventh report on the top 100 consumer AI apps surfaces actual U.S. credit-card spend for the first time, via a YipitData panel. The numbers are stark: the top percentile of payers averages $903 a month; the median customer spends $25. The top decile drives roughly half of all observed revenue, and those heavy users cluster in code, productivity, and creation tools — not general chatbots.

Paid penetration remains thin. Nearly half of U.S. consumers report some AI use, but only 25% use it daily. As of August, just 4.5% held an active personal subscription to ChatGPT, Gemini, or Claude. Most of the market still leans on free tiers or occasional use, and the current model — direct subscriptions plus usage-based billing — is likely capping deeper adoption.

ChatGPT's lead is unshaken: 2x Gemini's web visits, 6x Claude's; on mobile the gap widens to 2.5x Gemini and 14x Claude in MAU. Revenue data reinforces the picture — ChatGPT has 3x the U.S. paid subscribers of either rival. Claude, absent from the inaugural web ranking in September 2023, has cemented a clear #3 and passed Gemini in U.S. subscriptions earlier this year.

The business model is stuck in the past. Every dollar of consumer AI revenue still comes from direct subs or consumption billing, unlike previous waves where consumers were monetized indirectly via ads or transaction fees. That exclusive reliance on direct payment is probably slowing broader adoption. Meanwhile, free, developer-accessible personal assistants are starting to appear — a hint of where the market may move to reach beyond the 4.5%.

This edition introduces a permanent methodology shift: products built primarily for NSFW use are excluded from the general ranking. a16z stresses this doesn't reflect a demand drop, just a separate category. The ranking still leans on Similarweb for web and Sensor Tower for mobile, with only 11 new entries — the lowest in the series' history — signaling some stabilization at the top.
