ChatGPT Audience Doubles to 400 Million Weekly Users

ChatGPT’s user base continues to grow rapidly—according to OpenAI, the number of weekly active users has reached 400 million.

This is twice the number recorded in August 2024, when the platform had 200 million users, and 100 million morethan in December.

The company has not disclosed the exact number of ChatGPT Plus and ChatGPT Pro subscribers, but its B2B presencehas strengthened significantly. OpenAI now serves 2 million enterprise clients, double the number from September 2024. Additionally, API usage has doubled over the past six months.

OpenAI’s audience growth is particularly notable amid increasing competition. Recently, China’s DeepSeek introduced its own AI model, rapidly gaining popularity. The release of these new figures appears to be OpenAI’s way of demonstrating its market stability despite growing pressure from competitors.
