Do you trust that one dominant AI company is good for the future of technology?
As of August 2026, ChatGPT held a 79.4 percent share of the global AI chatbot market, based on web usage data. This milestone followed a period where the platform reached one billion monthly active users in May 2026.
Why it matters
The widespread adoption of generative AI, which contributed to a $172 billion annual consumer surplus in the U.S. by early 2026, reflects a massive increase in global engagement. Total time spent on these applications doubled to 36 billion hours in the first half of 2026 compared to the same period in 2025.
ChatGPT captured 79.4 percent of global web chatbot usage by August 2026, while Google Gemini trailed at 10.9 percent. In other metrics, DeepSeek accounted for 62.9 percent of token volume on the Vercel AI Gateway.
