China has taken a bite out of the U.S.’s lead in artificial intelligence.
The country has nearly closed its gap to the U.S. in AI bot performance, while continuing to best global competition in number of patents, publications, and rollout of robots, according to the Stanford University Institute for Human-Centered Artificial Intelligence (HAI) 2026 AI Index report released this week.
The report found a shrinking gap in Arena scores—a metric indicating relative performances of large language models—between the top AI bots in the U.S. and China. In May 2023, the U.S.’s top model, OpenAI’s GPT-4, led with more than 1,300 Arena points compared with China’s fewer than 1,000. By March 2026, that gulf shrank to just 39 Arena points, with the top U.S. model, Anthropic’s Claude Opus 4.6, leading China’s Dola-Seed 2.0 by just 2.7%.
While the U.S. still beats China in the number of top AI models—50 compared with 30—China has more publication citations than the U.S., accounting for 20.6% of AI citations in 2024 compared with the U.S.’s 12.6%. China also has nearly nine times the volume of industrial robot installations, leading the world with more than 295,000, compared with the U.S.’s 34,200.
“For years, the U.S. outpaced all other global regions on AI—in model size, performance, artificial intelligence research, citations, and more,” said Stanford’s summary of the report. “But China emerged as an AI counterweight to the U.S., gradually gaining ground, and this year it appears to have nearly erased any U.S. lead.”
China’s AI surge
Despite fewer investment dollars and wider regulatory constraints, China has changed the narrative of its ability to compete against the U.S. in a broader tech war. Spurred by its 2025 “DeepSeek moment,” China has poured funding into AI startups, with IPOs in Hong Kong last quarter reaching a five-year high of $110 billion across 40 new listings.
China has also quietly invested in its electricity infrastructure,…
