An Andreessen Horowitz report dated October 5 shows ChatGPT users leading consumer AI in August mobile rankings, web visits and observed US card spending, while paid usage is concentrated among a small minority. ChatGPT’s mobile app passed one billion monthly active users back in May 2026, according to Sensor Tower’s June report; that milestone did not occur this week.
The latest data shows that the consumer AI market is becoming much broader even as ChatGPT maintains a substantial lead. AI products now span coding, design, music, video, voice, productivity and autonomous agents, but usage remains relatively shallow for the average consumer. The report also shows that a small group of heavy users accounts for a disproportionate share of consumer AI spending.
Reporting note, 7 October 2026: This article covers a16z’s new seventh consumer-AI ranking, not a new one-billion-user milestone. Its web rankings use Similarweb visits, its mobile rankings use Sensor Tower active-user estimates, and its US spending analysis uses YipitData’s panel; those measures are not interchangeable with OpenAI’s global weekly active users. Original coverage by Chosun, Crypto Briefing and Clarity Today separately discuss the report’s spending divide. Each numerical comparison below remains attributed to its underlying a16z/Sensor Tower/YipitData dataset.
Key takeaways
- Sensor Tower says ChatGPT passed 1 billion mobile monthly active users in May 2026; October’s news is the new a16z ranking.
- ChatGPT has roughly 2.5 times Gemini’s mobile monthly active users and about 14 times Claude’s, according to a16z’s August data.
- Claude has climbed to No. 3 in web traffic, with nearly 1 billion monthly visits.
- ChatGPT has three times more U.S. consumer paid subscribers than Claude or Gemini.
- Only 4.5% of U.S. consumers in a16z/YipitData’s panel had a paid personal subscription to ChatGPT, Gemini or Claude in August.
- The top 1% of AI spenders accounted for 19.5% of observed consumer AI spending.
- Those top spenders spent an average of $903 per month, compared with roughly $25 for the median AI payer.
- AI is expanding beyond chatbots into coding, creative tools, agents, voice and hardware.
- a16z says the consumer AI industry may eventually need business models beyond subscriptions and usage-based pricing.
Why ChatGPT users still lead the consumer AI market
Three years after ChatGPT became the defining product of the generative AI boom, OpenAI’s chatbot remains at the top of the consumer market.
a16z’s latest ranking, published October 5, uses Similarweb data for web traffic and Sensor Tower data for mobile monthly active users. The firm says ChatGPT had a roughly twofold lead over Gemini in August web visits and a 2.5-fold lead on mobile. Its mobile monthly active user base was about 14 times larger than Claude’s.
The milestone is consistent with earlier Sensor Tower data. The analytics company reported in June that ChatGPT became the fastest mobile application to reach 1 billion monthly active users, reaching the milestone in May 2026, roughly three years after its launch.
That scale gives OpenAI an enormous distribution advantage.
Every new feature launched inside ChatGPT can potentially reach hundreds of millions of people without requiring users to discover a separate application. That becomes particularly important as OpenAI moves ChatGPT beyond a conventional chatbot into areas such as coding, research, productivity, shopping and autonomous agents.
Claude has become the market’s No. 3 player
The more surprising development in a16z’s latest ranking is Anthropic’s Claude.
Claude did not even appear on a16z’s first consumer AI web ranking in September 2023. It has now climbed to third place by web traffic, behind ChatGPT and Gemini, with nearly 1 billion monthly visits.
The rise reflects Anthropic’s increasing focus on professional and high-value users.
Claude has expanded beyond its original conversational interface with products including Cowork and Claude Design, while Anthropic has continued positioning the service heavily around coding, research, productivity and knowledge work.
a16z says Claude also passed Gemini among U.S. consumer subscribers earlier in 2026. Even after Google migrated legacy paid users to its broader AI plan, the two services remained roughly neck and neck in paid subscriptions.
That makes Claude’s position different from its raw traffic ranking.
It does not need to match ChatGPT’s total audience to become a commercially important competitor. Its focus on users who employ AI for coding, professional work and automation may produce higher revenue per user.
ChatGPT still has a major paid-subscriber advantage
Despite Claude’s growth, OpenAI maintains a substantial lead in monetization.
According to YipitData information included in the a16z report, ChatGPT has three times more U.S. consumer paid subscribers than Claude or Gemini.
This creates an important distinction between audience size and commercial performance.
A service can attract enormous amounts of traffic without converting a comparable percentage of those visitors into paying customers. Conversely, a smaller platform can generate substantial revenue if its users are willing to pay for expensive plans or high-value functionality.
Claude illustrates the second model.
a16z says 7.3% of Claude’s consumer payers are on Anthropic’s most expensive individual Max plan, which starts at $100 per month. The corresponding share is 1.3% for Google and 1.1% for ChatGPT on their respective $100 plans.
That suggests Anthropic has been particularly successful at monetizing a smaller but more intensive group of users.
Consumer AI usage remains surprisingly shallow
The headline numbers can make the AI market look almost universally adopted.
a16z’s data tells a more complicated story.
Nearly half of U.S. consumers now report using AI, but only 25% say they engage with AI daily. Furthermore, only 4.5% of consumers in the firm’s U.S. e-receipt panel had an active paid personal subscription to ChatGPT, Gemini or Claude in August.
In other words, awareness and experimentation are widespread, but habitual paid usage remains limited.
This creates a significant challenge for AI companies.
Traditional consumer internet businesses were able to monetize huge audiences through advertising, transactions or marketplace fees. Most generative AI companies have instead relied heavily on subscriptions and usage credits because running sophisticated models can be expensive.
The result is an unusual market in which billions of people may use AI products while only a relatively small percentage directly pay for them.
AI spending is concentrated among power users
The new a16z report provides another important insight: consumer AI spending is heavily concentrated.
Only 13% of users who pay for one AI product also pay for another AI tool. But among people who do spend heavily, expenditure can be extremely high.
The top 1% of AI spenders accounted for 19.5% of all observed consumer AI spending in the YipitData panel.
Their average monthly AI spending reached approximately $903 in August 2026, compared with roughly $25 for the median AI payer.
The top spenders also increased their spending by about 80% over the previous 18 months.
This group looks less like the average consumer and more like professional “prosumers” using AI to build products, automate work and create content.
Tools such as n8n, fal, Manus and Nous Research were among the products disproportionately purchased by these heavy spenders, while creative products including Higgsfield, Figma and HeyGen also benefited.
Consumer AI spending shows a power-law pattern
| User group | Average/observed spending pattern |
|---|---|
| Top 1% of AI spenders | ~$903/month |
| Median AI payer | ~$25/month |
| Top 1% share of observed spending | 19.5% |
| U.S. consumers with ChatGPT/Gemini/Claude paid subscription | 4.5% |

The figures show why raw user numbers alone can be misleading.
A company with 100 million relatively inactive users may not necessarily be more commercially valuable than one with 20 million users who rely on AI every day for professional work.
The consumer AI market is expanding beyond chatbots
Another major change highlighted by a16z is the diversification of the AI market.
Three years ago, the leading consumer AI products were overwhelmingly chatbots and image generators.
The current market includes:
- Coding platforms such as Cursor, Lovable and Replit
- Music-generation products such as Suno
- Voice platforms such as ElevenLabs
- Video-generation services such as Kling and Higgsfield
- Design products such as Figma
- AI agents such as Manus and Meta’s Muse
- Hardware products such as Plaud
- Productivity platforms such as Notion and Canva
This matters because the future consumer AI market may not be dominated by a single general-purpose chatbot.
Instead, general AI assistants could become platforms around which specialized applications compete.
OpenAI appears to be pursuing that platform strategy with ChatGPT, while Anthropic has concentrated more heavily on professional workflows.
Google, meanwhile, has the advantage of integrating Gemini across its existing ecosystem.
Claude’s rise comes despite signs of slowing momentum
Claude’s third-place position does not mean its growth is accelerating across every metric.
a16z’s YipitData data shows that Claude’s average daily sessions declined in July and August on its global desktop panel. Its U.S. e-receipt panel also showed slowing gross subscriber additions and increasing churn.
That suggests Anthropic may be moving into a more mature phase after its rapid expansion.
The company nevertheless retains a strong position among AI power users.
The challenge will be converting that professional popularity into broader consumer adoption without undermining the premium positioning that has helped Claude monetize.
ChatGPT regained momentum in the summer
While Claude gained ground earlier in the year, ChatGPT accelerated again following several major product releases.
a16z points to OpenAI’s July launches of GPT-5.6 Sol, Terra and Luna as well as ChatGPT Work as factors behind renewed momentum.
OpenAI has also expanded ChatGPT into areas that extend beyond simple question-and-answer interactions.
The company’s strategy increasingly resembles an attempt to make ChatGPT a general-purpose interface for digital work and everyday tasks.
That approach could strengthen user retention because the more services a consumer connects to an AI assistant, the harder it becomes to switch to another platform.
AI agents could change the consumer market again
The next competitive battle may be less about chatbots and more about agents.
AI agents are designed to carry out tasks rather than simply provide information. They can potentially browse websites, interact with applications, organize information and execute transactions on a user’s behalf.
a16z identifies products including Instinct, Tomo, Poke, Lindy, Town, Meta’s Muse, OpenAI’s Dots and xAI’s Grok Bot as part of this emerging category.
This could eventually create a new monetization model.
Instead of charging a monthly subscription, an AI agent could earn money by facilitating purchases, bookings or other transactions.
That would be closer to the model used by traditional marketplaces and payment platforms.
For AI companies, this could be particularly attractive because transaction revenue would allow them to monetize free users without requiring every customer to purchase a subscription.
The subscription model may not be enough
a16z argues that consumer AI’s dependence on subscriptions could eventually become a limitation.
Among the 44 AI-native products in its top web rankings, 84% offer subscriptions. Usage charges or additional credits are offered by 64%.
Only 14% have advertising, while just 2% generate revenue through transaction or platform fees.
That is very different from the pre-AI consumer internet.
Companies such as Meta and Alphabet built enormous businesses by providing free services and monetizing users indirectly through advertising. AI companies face higher computing costs, making the free-to-ad-supported model more difficult to replicate at an early stage.
However, falling model costs could eventually change that equation.
If companies can route simple requests to inexpensive models while reserving expensive frontier models for complex tasks, the economics of free AI products could improve.
OpenAI has the strongest combination of scale and monetization
The latest figures leave OpenAI with a particularly strong position.
ChatGPT leads mobile usage, web traffic and observed consumer spending, according to the different datasets used by a16z.
That combination is unusual.
It means OpenAI is not simply attracting large numbers of free users. It is also converting a meaningful portion of its audience into paying customers.
However, its lead should not be interpreted as an unassailable monopoly.
Sensor Tower previously reported that ChatGPT’s share of total AI-assistant users had fallen below 50% as Gemini and Claude gained ground. Its June data showed ChatGPT with more than 1.1 billion monthly users, compared with 662 million for Gemini and 245 million for Claude.
The market is therefore becoming more competitive even while ChatGPT remains far ahead in absolute scale.
What the numbers mean for OpenAI, Anthropic and Google
The three leading AI companies are increasingly pursuing different strategies.
OpenAI is trying to make ChatGPT a broad consumer and enterprise platform, combining conversational AI with coding, productivity, agents and other services.
Anthropic is leaning toward professional and prosumer users who value coding, automation, research and knowledge work and appear willing to pay more for advanced functionality.
Google can use Gemini’s integration with Search, Android and its broader software ecosystem to distribute AI at enormous scale.
That means the next phase of competition may not be decided solely by which company has the strongest model.
Distribution, product design, retention, integrations and monetization could become equally important.
India and other emerging markets could be critical
The next challenge for consumer AI companies is expanding beyond affluent users who can comfortably pay for premium subscriptions.
The a16z findings show that the highest-value AI users are currently concentrated among people who use AI for professional work and can justify substantial monthly spending.
Emerging markets offer a very different opportunity.
Large populations of users may be willing to use AI extensively but may not be willing to pay $20, $100 or more every month for a chatbot.
That makes lower-cost plans, advertising, commerce and transaction-based models potentially important for future expansion.
For companies such as OpenAI, Google and Anthropic, the ability to convert AI from a premium software product into a broadly accessible consumer utility could ultimately matter more than today’s leaderboard.
The Bigger Picture
The consumer AI race is entering a second stage.
The first stage was about proving that people wanted generative AI. ChatGPT effectively won that stage by becoming the category’s most recognizable product and reaching extraordinary user scale.
The second stage is about turning that attention into durable behavior and sustainable economics. Claude’s rise demonstrates that a smaller audience with intense professional usage can become commercially significant, while the enormous difference between the median AI payer and the top 1% shows how uneven monetization remains.
The biggest opportunity may therefore be outside the chatbot itself. Coding, creative work, autonomous agents, shopping and transactions could generate entirely new categories of consumer AI businesses.
Frequently Asked Questions
How many monthly users does ChatGPT have?
a16z says ChatGPT has more than 1 billion monthly active mobile users. Sensor Tower reported that ChatGPT crossed the 1 billion monthly active mobile-user milestone in May 2026.
Is Claude bigger than Gemini?
Not overall. Claude has risen to third place in web traffic, with nearly 1 billion monthly visits, but Gemini remains ahead of Claude in web traffic. a16z says Claude and Gemini are roughly neck and neck in paid subscribers.
Does ChatGPT make more money than Claude?
The latest a16z data strongly indicates that ChatGPT has a larger U.S. consumer paid base, with about three times as many paid subscribers as Claude or Gemini. However, this particular comparison should not be treated as a complete measure of total company revenue.
Why is Claude growing so quickly?
Claude’s growth has been driven by its strong positioning around professional and prosumer use cases, including coding, productivity, research and automation, alongside new products and models. a16z says Claude has now become the clear No. 3 consumer AI product by web traffic.
Looking Ahead
ChatGPT’s 1 billion-plus monthly mobile audience gives OpenAI an enormous lead, but the latest numbers also show why that lead cannot be taken for granted. Gemini continues to benefit from Google’s ecosystem, Claude has established itself as a serious professional AI platform, and new agents such as Muse and Dots are changing what consumers expect an AI product to do.
The next major shift could come from monetization rather than user growth. If AI companies can move beyond subscriptions toward advertising, commerce and transaction-based revenue, they may be able to serve much larger populations of free users while still covering the cost of inference. The company that best combines massive distribution, high-frequency usage and sustainable economics could ultimately define the next generation of consumer AI.
For Indian readers, this is a useful contrast with OpenAI’s new visual-ad test and the Meta Muse business rollout: both pursue monetization and distribution, but neither changes the US panel nature of a16z’s spending figures. India-specific paid conversion cannot be inferred from those US estimates.
