OpenAI advertising business reaches $1 billion annual run rate

OpenAI announced that its ChatGPT advertising business has reached a $1 billion annualized revenue run rate in under 200 days. The milestone comes as OpenAI seeks to justify its $852 billion valuation ahead of a highly anticipated initial public offering. Despite CEO Sam Altman previously calling ads a 'last resort,' the company is expanding the program to over 40 countries and launching self-service ad tools in Europe, India, and the Middle East, drawing mockery from rival Anthropic.
