OpenAI's ChatGPT has surpassed one million business clients globally as of November 5, 2025, establishing it as the fastest-growing business platform in history. This milestone coincides with a series of significant product enhancements, including a new AI shopping assistant and the release of GPT-5.1, even as the company navigates increasing legal challenges related to content moderation and copyright.
In November 2025, OpenAI introduced an AI shopping feature within ChatGPT, enabling users to research purchases and receive product recommendations. Concurrently, the company integrated ChatGPT's voice mode directly into its main chat interface and rolled out a group chat feature globally to all users. A key technological update, GPT-5.1, was released with two models: "Instant," designed for conversational interactions, and "Thinking," offering faster task handling and enhanced reasoning. Earlier, in October 2025, OpenAI partnered with Walmart, Etsy, and Shopify to integrate shopping capabilities, and expanded its developer tools to allow for app building directly within ChatGPT.
The rapid expansion of ChatGPT has been met with increased legal challenges. In November 2025, OpenAI faced multiple lawsuits alleging negligence related to ChatGPT's role in suicides and psychiatric harm, particularly concerning the GPT-4o model. The company, in court filings, denied liability, arguing misuse of the chatbot while also announcing new safeguards and parental controls in response to earlier lawsuits in August and September. Additionally, a Munich court ruled against OpenAI in November 2025, finding ChatGPT in violation of German copyright law for reproducing protected song lyrics. The company also faced a temporary ban on using "cameo" for Sora features due to a trademark lawsuit. OpenAI has stated that ChatGPT handles over one million suicide-related conversations weekly and has improved its responses by consulting mental health experts.
Beyond recent developments, ChatGPT's user base has demonstrated substantial growth, reaching 800 million weekly active users in October 2025, up from 700 million in August. The mobile application has generated over $2 billion in global consumer spending since its May 2023 launch, with $1.35 billion accumulated in 2025 alone, according to Appfigures data. OpenAI has also pursued strategic market expansion, offering an affordable ChatGPT Go plan in 16 Asian countries and providing ChatGPT Enterprise to U.S. federal agencies for a nominal fee. The company reportedly projects its revenue to triple to $12.7 billion in 2025, reflecting its aggressive market penetration and continued investment in AI infrastructure.
