Blockchain intelligence company AMLBot's monitoring data shows that recently Polymarket users on the Polygon network had approximately $3.1 million PUSD stolen due to a front-end malicious script intrusion.The attackers implanted a malicious script that induced users to sign authorization transactions (involving EIP-7702 delegated execution), resulting in the users' wallets being emptied. The stolen funds were then converted to USDC.e through Relay, bridged to Ethereum, and ultimately exchanged for ETH, which was concentrated in a designated address. Currently, about 1891.9 ETH is distributed across three new wallets.AMLBot pointed out that this attack is similar to the incident involving the 2024 1inch web application, where a wallet theft script was implanted in the Lottie Player library, both cases involved third-party scripts being compromised, leading to front-end contamination.

Polymarket's Vice President of Product Engineering and former Craft co-founder Balint Orosz tweeted that Polymarket has acquired the productivity app Craft Agents, and some team members from Craft will join Polymarket.

According to the Wall Street Journal, several U.S. lawmakers are calling for an investigation into the prediction market platform Polymarket, as its advertising is alleged to potentially contain misleading content.It is reported that the lawmakers believe Polymarket may not clearly disclose the nature of its products and associated risks in its marketing, which could mislead users. Some legislators have requested regulatory agencies to intervene and assess the compliance of its advertising and information disclosure standards.

According to CNBC, Polymarket stated that its annual revenue has significantly exceeded $1 billion, a development that comes just six weeks after its U.S. trading platform lifted the waiting list. The platform operates independently from its international DeFi prediction market and will gradually expand user access after its launch in December this year.Driven by the FIFA World Cup, the trading activity in the prediction market has significantly increased, with trading volumes across multiple platforms rising simultaneously. Data shows that the daily trading volume on the U.S. platform has grown from about $50 million in mid-May to over $200 million on June 20 (based on Dune Analytics data).Meanwhile, its international platform set a record for weekly trading volume during the World Cup, reversing the downward trend seen in April and May. The U.S. business was previously restricted due to regulatory issues in 2022, but resumed operations in the form of a regulated exchange after the U.S. Commodity Futures Trading Commission (CFTC) and the Department of Justice dropped their investigation and did not file charges in 2024.Currently, the U.S. platform is primarily mobile-based, requiring users to download the app via a QR code to trade, with the desktop version not yet available. Polymarket stated that it will continue to optimize market experience, liquidity, and product design to enhance both institutional and consumer-level experiences in the prediction market.

According to the official announcement, Gate has optimized and upgraded the VIP level evaluation rules.

According to data from @defioasis, the total amount of Polymarket pUSD has surpassed 500 million dollars, with the total number of holders exceeding 1 million. Among them, 567 addresses hold more than 100,000 pUSD, meaning that 0.06% of addresses hold 55.34% of the pUSD balance; addresses holding more than 1,000 pUSD account for 2.76%, collectively holding 90.34% of the pUSD balance; 51.96% of holders possess less than 10 pUSD, which only accounts for 0.19% of the pUSD balance. pUSD represents the cash flow balance of Polymarket users. Although some users have all their funds tied up in positions, this still reflects the extreme wealth disparity phenomenon in the prediction market.

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.

On-chain security analyst Specter stated that a phishing attack suspected to target Polymarket users is currently occurring, with total losses amounting to approximately $2.94 million.According to its monitoring, attackers have transferred funds from more than 11 victim wallets holding PUSD, converting the stolen assets into ETH, while reminding users to be cautious of phishing risks and stating that the incident is still under ongoing investigation.

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. The CFTC released a 267-page rule proposal on June 10, intending to allow most sports contracts but prohibiting in-game betting and college pre-game sports, with a 45-day public comment period.

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.

According to official news, Polygon Labs announced that it will take down the Polygon zkEVM Mainnet Beta sequencer on July 1, 2026, and the timeline was first announced in June 2025.The official reminder states that on-chain wallet assets must be bridged to the Ethereum mainnet via ui.agglayer.dev before this date. On-chain wallet balances that are not bridged in time will be automatically migrated to Ethereum L1 and can be claimed through a dedicated interface afterwards.Polygon emphasizes that it does not control any DeFi protocols on zkEVM, and assets locked in DeFi contracts cannot be automatically migrated. Protocol teams and users must proactively withdraw and migrate liquidity before July 1. Assets that are automatically migrated and not claimed by the deadline will be considered abandoned after December 31, 2027.

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.
