According to Cointelegraph, a study based on 857,000 active users of Polymarket shows that about 60% of users who placed their first bets during the World Cup had never interacted with blockchain protocols before.Alvin Kan, Chief Operating Officer of Bitget Wallet, stated that prediction markets have changed the traditional logic for crypto users to get involved—users no longer need to understand blockchain technology first, but can participate directly because they have opinions on real-world events. This has made prediction markets a new entry point for some users into the crypto space.Data shows that the trading volume of Polymarket's World Cup champion contracts has exceeded $3.1 billion, with sports contracts contributing over $4.9 billion in trading volume to Polymarket in the past 30 days, and reaching $8.5 billion on Kalshi, becoming the main trading category on both platforms.

According to a report by The Wall Street Journal, the prediction market platform Polymarket is suspected of paying dozens of social media creators to instruct them to record fake betting and high-profit videos on a simulated website that closely resembles the official site, using this as a promotional tactic to attract new users. The report indicates that the campaign required creators to conceal the official sponsorship relationship and specifically targeted the domestic audience in the United States.The investigation shows that the related marketing videos have accumulated over 140 million views on platforms such as TikTok, YouTube, and Instagram, involving up to $1.9 million in false bets. In response, Polymarket did not directly address the specific details of the investigation but stated in a statement that, as part of promoting industry transparency, the platform is conducting a comprehensive audit of active promotional content to ensure it strictly complies with internal standards and applicable regulatory and legal disclosure requirements.

Kalshi CEO Tarek Mansour stated in an interview with Front Office Sports that he does not view Polymarket as a primary competitor, but is more concerned about the threats posed by CME Group, Robinhood, and sports betting operators. According to data from Bank of America analysts, Kalshi holds about 91% of the regulated prediction market share in the U.S., with approximately $1 billion of the $1.6 billion in open contracts in the industry, and has listed about 97% of active markets.In the past 30 days, Kalshi's trading volume was approximately $9.8 billion, close to Polymarket's $9.9 billion. CME launched FanDuel Predicts in partnership with FanDuel last December; Robinhood began shifting some contracts to its Rothera platform in collaboration with Susquehanna after building a prediction market based on the Kalshi exchange in 2025.Mansour called for Polymarket to be included in a regulatory framework, stating that insider trading cases on its offshore platform harm the entire industry.

According to BBX data, yesterday's interest rate hike in Japan coincided with the Federal Reserve's decision window, creating the most intense macroeconomic shock point of the week. The latest results of institutional stablecoin research were released on the same day, with the core dynamics as follows:Metaplanet Inc. (TSE: 3350), as the largest corporate BTC reserve holder in Asia and the third largest publicly traded company holding Bitcoin globally (holding 40,177 BTC at an average price of about $104,000, with a target of 100,000 BTC by the end of 2026), faced a dual-edged sword pressure from the exchange rate yesterday: after the Bank of Japan announced a 25 basis point increase in the policy interest rate to 1.0%, the yen strengthened, superficially lowering the book value of BTC denominated in yen, but Bitcoin subsequently rose against the trend (CoinDesk's headline on the same day: "Bitcoin rallies after Japan rate increase"), with actual improvements in USD-denominated holdings. The company's current holdings are approximately $2.64 billion (estimated at $65,750/BTC), with the latest capital move being the issuance of 8 billion yen (about $55 million) for the 20th bond (EVO FUND) on April 24 for additional BTC purchases. Analysts warn that if the BOJ's interest rate hike triggers large-scale unwinding of "Yen Carry Trade," global risk assets including BTC may suffer systemic deleveraging shocks—however, Metaplanet holds physical BTC rather than leveraged positions, with its main risk being the exchange rate conversion effect rather than forced liquidation.OSL Group (Hong Kong Stock Exchange: 0863.HK) and the School of Business at the Hong Kong Polytechnic University jointly released a white paper on June 16 (The Block included it on the same day at 9:01 am EDT), titled "Cross-Border Trade Payments Will Drive the Adoption of Regulated Corporate Stablecoins." The core conclusion is that the demand for corporate-level cross-border trade payments is the main path to drive the large-scale adoption of regulated stablecoins, with importance surpassing retail consumption scenarios. OSL Group holds the Hong Kong Securities and Futures Commission licenses 7 (automated trading services) and 1 (securities trading), making it one of the few compliant exchanges globally with both institutional custody and practical experience in stablecoin settlement. Previously, it provided institutional clients with approximately $130 million in USDGO stablecoin settlement services in April 2026. This white paper provides an industrial basis for the stablecoin policy framework of Hong Kong's financial regulatory authorities, and, together with Visa's stablecoin settlement of $7 billion annualized scale, SoFi SoFiUSD's launch, and Western Union's USDPT layout, constitutes multiple points of evidence accelerating the global adoption of corporate stablecoins.

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.
