OpenAI reports ChatGPT advertising revenue reaches one billion dollars amid rapid global expansion.

OpenAI Korea said the number of companies adopting ChatGPT Enterprise increased 28-fold during the year after the company established its Korean office, citing Samsung Electronics and Seoul National University as representative users.
OpenAI Korea said Samsung Electronics has implemented ChatGPT Enterprise across all of its employees and is collaborating with OpenAI on next-generation chip research and the Stargate project.
ChatGPT became the official associate partner of India’s home bilateral cricket matches through March 2028, paying ₹1.2 crore per match—the same rate as SBI Life and just below Campa Cola’s ₹1.31 crore winning bid.
ChatGPT’s advertiser base grew from roughly 300 brands in April 2026 to more than 820 in July, according to Sensor Tower data cited by Business Insider, indicating rapid early experimentation with the advertising channel.
Anthropic’s Claude recorded approximately 640% year-over-year monthly active-user growth in the second quarter of 2026, reaching about 56 million monthly active users and underscoring the competitive pressure facing OpenAI.
OpenAI's advertising business has hit an annualized revenue run rate of roughly $1 billion, according to The Information, marking a stunning entry into ad sales within months of launch. The company now counts tens of thousands of advertisers across more than 40 countries, signaling rapid early traction as ChatGPT pursues advertising alongside enterprise sales as a core revenue pillar.
The growth comes as ChatGPT surpassed 1 billion monthly mobile users and annualized revenue reportedly reached $40 billion by August 2026, according to Reuters, while enterprise subscriptions have now overtaken consumer revenue. OpenAI says its ads could blend Google-like insight into user intent with Meta-like personalization based on conversation history and user memories.
OpenAI is deepening its partnership with Samsung Electronics to co-develop next-generation AI chips, according to Yahoo Finance. Harrison Kim, General Manager of OpenAI Korea, stated that chip development is a key area of collaboration. Samsung is also implementing ChatGPT Enterprise across all of its employees and working with OpenAI on the Stargate infrastructure project.
OpenAI Korea reported a 28-fold increase in companies adopting ChatGPT Enterprise over the past year, with Samsung Electronics and Seoul National University named as representative customers, according to Tom's Hardware. The Samsung partnership suggests OpenAI believes it needs manufacturing scale beyond its existing relationship with TSMC.
OpenAI's advertiser base nearly tripled in just three months. Sensor Tower data cited by Business Insider shows advertiser count jumped from roughly 300 brands in April 2026 to more than 820 in July. This rapid growth reveals how quickly companies are testing the new ad platform despite it still being an early-stage experiment.
OpenAI has built safeguards into its ad system, stating that advertisers cannot influence the responses users receive from ChatGPT. Ads initially appear separately from ChatGPT's answers, according to The Information, keeping sponsored content visually distinct from the AI's core functionality.
ChatGPT became the official associate partner of India's home bilateral cricket matches through March 2028, according to Cricinfo, paying ₹1.2 crore per match. This put ChatGPT at the same sponsorship rate as SBI Life and just below Campa Cola's winning bid of ₹1.31 crore. The move shows OpenAI's willingness to spend on high-profile consumer brand placements.
Anthropic's Claude is gaining momentum against OpenAI. Claude recorded approximately 640% year-over-year monthly active-user growth in Q2 2026, reaching about 56 million monthly active users, according to Analytics data cited by Axios. The explosive growth underscores the competitive pressure OpenAI faces even as it expands into advertising and enterprise markets.
