ChatGPT Surges to 900M Users Amid Massive Funding Boost
OpenAI announced that ChatGPT has reached 900 million weekly active users and now counts 50 million paying subscribers. The new figure is a 100 million-user increase from the 800 million reported in October 2025. OpenAI also disclosed it has raised $110 billion in private funding in a round that includes a $50 billion investment from Amazon and $30 billion each from Nvidia and SoftBank, valuing the company at a $730 billion pre-money valuation. The funding round remains open, and OpenAI said subscriber growth accelerated in January and February, driving product improvements in speed, reliability, and safety.
Major usage milestone (near 1B weekly users) and an unprecedented $110B private funding round with large strategic investors — a company-level event with broad implications for conversational AI, platform reach, monetization and advertising channels.

Recent verified developments and strategic activity across this market segment.
ChatGPT Reaches 1 Billion Monthly Users
ChatGPT surpassed 1 billion global monthly active users in May, roughly three years after its launch, according to Sensor Tower estimates — the fastest any app has reached that milestone. The newsletter highlights that this scale grants OpenAI unparalleled distribution, compounding advantages in data, feedback and pricing power, but notes that monthly active users are not equivalent to paying customers and inference costs make large free usage costly. The piece also cites that Anthropic’s Claude has roughly 56 million users, and emphasizes that converting reach into paid customers will determine whether the lead converts into sustainable business value.

ChatGPT Reaches One Billion Monthly App Users
OpenAI’s ChatGPT reached one billion monthly app users in May 2026, according to Sensor Tower estimates, making it the fastest app to hit that milestone (about 3.5 years after its November 2022 launch). Sensor Tower data shows competitors — including Anthropic’s Claude, Google’s Gemini, ByteDance’s Doubao/Dola and Meta AI — have posted much higher year‑over‑year growth rates even as ChatGPT maintains a sizable lead. Public sentiment toward AI has cooled amid protests and concerns (including reactions to OpenAI’s February agreement to deploy models on Pentagon networks), but analysts and polls cited in the article argue that sentiment-driven dips are unlikely to derail broader adoption. The report also notes recent IPO filings from Anthropic and OpenAI and highlights industry research showing rising workplace AI usage and large projected market value for AI over the coming decade.
OpenAI Earns $100M from ChatGPT Ads
OpenAI has begun testing advertising inside ChatGPT for U.S. users on the Free and Go tiers and reportedly generated about $100 million in recurring annualized revenue from ads within two months of the test. ChatGPT had roughly 900 million weekly active users as of February 2026, but most do not pay for subscriptions, motivating ad monetization. OpenAI told investors it targets $2.5 billion in ad revenue by the end of 2026, $53 billion by 2029, and roughly $100 billion by 2030—projections that assume ChatGPT reaches 2.75 billion weekly users by 2030. Early rollout drew criticism for irrelevant or intrusive placements and advertisers reporting no measurable business outcomes. OpenAI plans additional ad features (a push option) despite concerns that ads could undermine user trust and drive some users to competitors.
