China staged a show of force in artificial intelligence this week, pairing a high-profile political endorsement with a bold product launch that rattled US markets.

According to Shoreline Media Group, President Xi Jinping addressed an artificial intelligence conference in Shanghai, lending top-level backing to the country's ambitions. The gathering coincided with a wave of domestic announcements. Pandaily reports that Chinese-made chips are now underpinning homegrown AI models at the World AI Conference (WAIC), describing the country's domestic computing infrastructure as reaching a "tipping point."

The centerpiece was Moonshot AI's new model, Kimi K3. The BBC reports that Moonshot claims Kimi K3 can rival the systems built by OpenAI and Anthropic, the leading American AI labs. Taipei Times and China Daily also covered the unveiling, with China Daily saying the model "pushes boundaries." Crypto Briefing framed it as a direct challenge to OpenAI and Anthropic's dominance.

The launch landed hard on Wall Street. BeInCrypto asked whether "the American AI boom is over" after Kimi K3 hit US stock markets. According to MSN's markets coverage, Moonshot AI added to chip investors' worries, with a Friday selloff capping what it called "a brutal week" for stocks that were once the market's favorites.

Why it matters: a credible, cheaper Chinese challenger built on domestic chips could reshape both the global AI race and the investor bets underpinning America's tech boom.
