In the increasingly competitive field of artificial intelligence, OpenAI CEO Sam Altman delivered an encouraging message to employees and investors: the monthly growth rate of its AI chatbot ChatGPT has returned to over 10%. As competitor Anthropic continues to launch new tools, OpenAI faces increasing pressure, but the company still maintains strong growth momentum.
According to internal Slack messages, last Friday, Altman mentioned in his communication with employees that ChatGPT's weekly active users have exceeded 800 million. At the same time, he also revealed that OpenAI's code product Codex saw a 50% increase in users in the past week. Codex is now in fierce competition with Anthropic's Claude Code, which also achieved significant user growth over the past year. Recently, OpenAI released a new version of the Codex model - GPT-5.3-Codex, and launched a standalone app for Apple computer users, further expanding its market influence.
Although the company faces some controversies while developing rapidly, such as Anthropic joking about OpenAI's plan to insert advertisements in Super Bowl ads, Altman quickly responded on social media, calling these ad contents "misleading." However, according to internal information, OpenAI will begin testing ad functions within ChatGPT this week, and these ads will be clearly marked without affecting users' answers.
At the same time, OpenAI is about to complete a funding round worth $100 billion. According to sources, Altman and Chief Financial Officer Sara Fleischmann are working hard to tell the company's growth story to investors. In non-public meetings, executives emphasized OpenAI's significant advantages in end-user base, enterprise business, and computing resources. It is expected that the funding negotiations will enter a critical phase in the next two weeks. OpenAI previously completed a $41 billion funding round in 2025, with investors including SoftBank, Microsoft, and NVIDIA.
In the digital advertising market, although currently dominated by companies like Google and Meta, OpenAI expects that in the long term, advertising revenue will account for a small portion of total income. Looking ahead, OpenAI's continuous growth and innovation will certainly further drive the development of the AI industry.
