The market is bigger than last year and smaller than it sounds
Andreessen Horowitz published the seventh edition of its Top 100 Gen AI Consumer Apps ranking on 5 October, compiled by Olivia Moore from three sources: Similarweb for web traffic, Sensor Tower for mobile, and YipitData panel data for US consumer spending.
The headline number is a denominator. As of August 2026, a16z puts active paid personal subscriptions to ChatGPT, Gemini or Claude at 4.5% of US consumers. That is more than double the 2.1% of a year earlier, and it is still a small fraction of a country where, by the same report, nearly half of consumers say they use AI and about 25% engage with it daily.
ChatGPT’s lead is wider on money than on traffic
The report puts ChatGPT roughly 2x ahead on web visits and 2.5x ahead on mobile users — and 3x ahead on US consumer paid subscribers. The gap between the usage lead and the revenue lead is the finding worth pausing on: whatever share of attention competitors have taken, they have taken less of the wallet.
Switching barely happens either. a16z reports that only 8% of US ChatGPT subscribers also subscribe to Claude, and that just 13% of people who pay for one AI product pay for any other. The consumer AI market, on this data, is not a basket of complementary tools. It is a set of single-vendor households.
Spending is concentrated on top of that. The top 1% of spenders account for 19.5% of all observed consumer AI spend, with an average of $903 a month against $25 for the median payer.
The list itself has gone quiet
The other signal is what did not change. Only 11 products appeared for the first time in this edition — the smallest number of debuts across all seven lists a16z has published.
For a sector whose funding rounds have run at record size through 2026, a consumer ranking with almost no new entrants is an awkward data point. It suggests the money is going into infrastructure, enterprise deployment and model training rather than into new consumer products that reach the top 100.
Two caveats are worth keeping. This is a venture firm’s analysis of a market it invests in, drawn from third-party panel and traffic estimates rather than company-reported figures, so the levels should be read as estimates. And “US consumers” is a narrow lens on a market whose largest growth is not in the United States. The trend lines — doubling paid penetration, concentrated spend, almost no cross-subscription — are the part worth carrying forward.
