ChatGPT Surpasses 400M Weekly Users Amid Competition

OpenAI's ChatGPT has reached a significant milestone of 400 million weekly active users, marking a 33 percent increase since December. This growth trajectory reflects the platform's rising popularity among both individual users and businesses, with enterprise subscriptions doubling to over 2 million. OpenAI's COO, Brad Lightcap, emphasized that the increase is driven by user satisfaction and word-of-mouth recommendations. Despite facing stiff competition from rivals like Elon Musk's xAI and China's DeepSeek, OpenAI continues to solidify its position in the market. The company is also navigating challenges related to its transition to a for-profit model and legal disputes with Musk. Looking ahead, OpenAI plans to simplify its offerings and introduce new models, GPT-4.5 and GPT-5, to further expand its user base.
