The Japanese cryptocurrency exchange Bitbank today issued a risk warning to users regarding the use of prediction market services such as Polymarket.The announcement pointed out that prediction platforms that trade on future events, elections, or sports results using cryptocurrency assets are mostly operated by overseas institutions. If users access these platforms from within Japan and participate in trading for the purpose of making financial gains, they may be suspected of violating Japan's relevant gambling regulations.Bitbank emphasized that if the platform detects withdrawal and deposit records related to prediction markets or suspected related services in a user's account, it may implement suspension measures on that account. Once an account is suspended, the user will be unable to log in, trade, or withdraw and deposit cryptocurrency assets and yen, and the platform will not be responsible for any losses incurred as a result.

According to Abcnews, several prediction market platforms including Kalshi, Crypto.com, and Polymarket have formed an alliance and filed a lawsuit in state court this Friday, attempting to block Kentucky's newly implemented 14.25% prediction market transaction tax.This tax was passed by the Kentucky legislature in April of this year, targeting transaction fees on prediction market platforms, with a rate of 14.25%, which is higher than the local horse racing industry's tax burden of about 9.75%. The plaintiffs in the lawsuit claim that the tax is discriminatory, unconstitutional, and may conflict with federal law.Prediction market platforms allow users to trade contracts on real-world events (such as economic data, election results, etc.), essentially belonging to the event derivatives market. The plaintiffs argue that this tax will significantly raise compliance costs and may force trading activities to shift to offshore platforms with weaker regulations.Kentucky Attorney General Russell Coleman stated that he will vigorously defend the law in court and asserted that the state government is capable of handling the related challenges.Meanwhile, Kalshi stated that excessive state-level tax burdens will weaken the competitiveness of the legal market and may drive users to illegal trading platforms that lack regulation and protection.This case is seen as the latest development in the ongoing conflict between the U.S. prediction market industry and state regulatory and tax systems.

According to Fortune, Mastercard has announced a new protocol called Agent Pay for AI, allowing AI agents to make payments and conduct small transfers among themselves— for example, automatically paying when an AI agent retrieves data from a website in segments. The protocol stores the permissions granted to AI agents by humans on the blockchain, initially using the Polygon network to ensure transparency and verifiability, allowing multiple parties to verify whether the agents are acting as instructed.Companies like Adyen, Coinbase, and Cloudflare are collaborating with Mastercard to develop this protocol. Mastercard's Chief Product Officer Jorn Lambert stated that this protocol will not become a major source of revenue in the short term, but it is expected to develop into a significant new market over the next five years.Giants like Visa, Stripe, Coinbase, and Google are actively laying out AI payment protocols, jointly promoting the future of "machine-to-machine payments" and AI chatbots dominating e-commerce transactions; however, the current volume of agent-based payments remains relatively small.
