Anthropic Accuses Alibaba of Claude “Distillation” Campaign, Pushing Polymarket Odds Higher in “Best AI Model by End of

A report that Anthropic accused Alibaba of a large-scale effort to extract Claude’s capabilities has coincided with a firmer Polymarket pricing for Anthropic in the contract “Which company has best AI model end of July?”. On Polymarket, Anthropic remained the clear favorite as traders pushed its implied odds higher versus rivals.

Key Takeaways

Polymarket prices Anthropic as the front-runner at 85.5% to have the best AI model by end of July 2026.
The market moved up for Anthropic after news tied to alleged attempts to clone Claude, reinforcing expectations it stays ahead of competitors.
The contract is scheduled to resolve on July 31, 2026, with $1,800,669 in traded volume so far.

Anthropic alleged that Alibaba launched what it described as its largest measured campaign to illicitly extract Claude’s capabilities, according to a June 10 letter sent to Senators Tim Scott and Elizabeth Warren ahead of a Senate committee hearing on “AI and the American Dream.” Anthropic said the activity ran from April 22 to June 5 and involved more than 28.8 million exchanges with Claude using almost 25,000 fraudulent accounts tied to operators affiliated with Alibaba and its Qwen AI lab. The company said the effort targeted high-value capabilities including agentic reasoning, software engineering and long-horizon tasks, and that it used obfuscation techniques and proxy networks to evade detection. Anthropic also argued that such “distillation” attacks effectively transfer U.S. investment and R&D value to geopolitical competitors, and said similar tactics have been discussed by other AI developers. The report said Alibaba could not immediately be reached for comment, and also described a lawsuit in which Alibaba challenged a U.S. government designation it said had no factual or legal basis.
