According to Odaily Seer, an account with over $210,000 in profit (0x1136368d7f6728e94ed14c532ab95a932f710c2e) purchased approximately $54,000 worth of bets on the Montreal Canadiens defeating the Carolina Hurricanes in the Polymarket NHL Eastern Conference Finals prediction event. The opening price was 42.8¢, resulting in a floating profit of $3,200. Currently, the NHL Eastern Conference Finals series is tied 1-1. The Canadiens previously defeated the Hurricanes 6-2 in Game 1, but were subsequently tied by their opponents. In Game 3, the Canadiens have home-court advantage, while the Hurricanes are favored by some market participants due to their more consistent goaltender performance and special teams efficiency.

Odaily Seer's monitoring shows that Polymarket has launched a new prediction event: "Will Cristiano Ronaldo and Ronaldo Jr. play together in an official professional match before December 31, 2026?" The 41-year-old Ronaldo's contract with Al-Nassr runs until 2027. Although Ronaldo Jr., who will soon turn 16, is currently playing in the club's youth academy, recent reports indicate that top European clubs, including Real Madrid, are showing strong interest in him, and Ronaldo Jr. himself prefers to be tested in elite European youth academies. However, achieving rapid promotion and first-team appearances within the limited window before the end of 2026 remains a significant hurdle.

According to Huoxun Finance, Indonesia's Ministry of Communications and Digital Affairs recently banned the prediction market platform Polymarket, deeming it an online gambling platform for offering betting on uncertain events, which violates local laws. Polymarket had previously launched a betting market on when Indonesian President Prabowo Subianto would step down, with his term originally scheduled to end in 2029. This betting platform went live the day after Prabowo announced plans to tighten controls on exports of commodities such as coal and palm oil, sparking discussion on local social media. Indonesian authorities also stated they are investigating all social media accounts associated with Polymarket.

Odaily Planet Daily reports that prediction market platform Kalshi has announced its support for the formation of a new prediction market lobbying group, Americans for Fair Markets, and has appointed former White House Deputy Chief of Staff Taylor Budowich as a strategic advisor. This group will challenge the sports betting and casino industries, which it believes are attempting to “maintain their monopoly and spread misinformation about prediction markets to policymakers.” Americans for Fair Markets will reportedly push for federal-level prediction market regulation and launch paid advocacy campaigns to counter what it calls “false narratives” about prediction markets. The group will also join a broader industry lobbying effort, including the Coalition for Prediction Markets, backed by Coinbase, Crypto.com, and Robinhood, which is scheduled to launch in December 2025. On the same day, the U.S. House of Representatives launched an investigation into Kalshi and its main competitor, Polymarket, focusing on how the platforms handle insider trading. As prediction markets face stricter scrutiny in the U.S. and globally, related regulatory controversies continue to escalate. Kalshi stated that the new organization will support the U.S. Commodity Futures Trading Commission's regulation of prediction markets and will support KYC, insider trading bans, and restrictions on markets involving violence and terrorism under federal regulations. John Bivona, Kalshi's head of government relations, said, "We will not lose out to vested interest groups trying to maintain their monopoly interests in terms of funding or organizational capacity."

According to BBX data, the cryptocurrency prediction market is facing increasing regulatory pressure, leading to a simultaneous expansion of institutional-grade cryptocurrency derivatives product lines. On May 22, James Comer, Chairman of the House Oversight and Government Reform Committee, issued investigative letters to Kalshi and Polymarket, initiating a congressional investigation into insider trading on prediction market platforms. The investigation focuses on two suspicious bets made hours before the public disclosure of events: betting on the arrest of Venezuelan President Maduro and the outcome of the Iranian conflict. The Wisconsin Attorney General recently named Robinhood, Kalshi, Polymarket, and Crypto.com as defendants, accusing them of providing unlicensed sports betting services in Wisconsin. This is the latest development in the escalation of prediction markets to congressional scrutiny after facing legal challenges in 13 states. Both platforms have stated their willingness to cooperate with the investigation, claiming they have robust anti-insider trading mechanisms. On May 23, the U.S. Securities and Exchange Commission approved a proposal submitted by Nasdaq, allowing it to list cash-settled Bitcoin index options on the Philadelphia Stock Exchange. These options do not involve physical delivery of Bitcoin and provide institutional investors with a standardized tool to hedge or invest in Bitcoin price volatility. This fills a market gap for such derivatives on regulated exchanges in the United States. The timing of the approval coincides with significant Bitcoin volatility during the week, reflecting the accelerated release of market demand for volatility management tools.

According to Odaily Planet Daily, several career officials at the U.S. Commodity Futures Trading Commission (CFTC) have been dismissed for raising compliance concerns about Polymarket, Crypto.com, and Gemini Titan, all of which are alleged to have business ties to the Trump family. The report states that then-CFTC Acting Chair Caroline Pham and senior legal counsel Brigitte Weyls were involved in the review process, helping these companies obtain approval or evade further investigation. Both subsequently joined MoonPay and Gemini Titan, respectively. It is understood that officials had previously expressed concerns about Crypto.com's unfair treatment of small retail investors, Polymarket's inadequate anti-fraud mechanisms, and Gemini Titan's failure to complete the necessary approvals for operation. Furthermore, the report points out that during Trump's second term, the CFTC has dropped at least five crypto investigations and has only publicly announced two enforcement cases involving digital assets, both against individual operators; in contrast, the Biden administration saw over 80 related cases. (The New York Times)

According to a New York Times investigative report, several senior CFTC officials who raised regulatory concerns about Polymarket, Crypto.com, and Gemini, companies with business ties to the Trump family, have been suspended, placed under internal investigation, and forced to resign. The report states that then-CFTC Acting Chair Caroline Pham and her senior advisors intervened to help these companies obtain necessary approvals. In late 2025, five officials who raised questions or enforced crypto regulations were placed on administrative leave and placed under internal investigation without being given specific reasons. After leaving CFTC, Pham joined MoonPay, a crypto company that partnered with Polymarket, while her senior advisor, Brigitte Weyls, became general counsel for Gemini Titan, whose application was approved with her involvement. On the enforcement front, the CFTC has withdrawn at least five crypto investigations, and the number of enforcement actions has plummeted from over 80 during Biden's presidency to only two during Trump's term. A White House spokesperson denied any conflict of interest, stating that President Trump would only act in the best interests of the American public.

According to Odaily Planet Daily, several senior officials at the U.S. Commodity Futures Trading Commission (CFTC) who raised compliance concerns about prediction market platforms were subsequently suspended, subjected to internal investigations, and ultimately forced to resign. The report states that these officials raised concerns about the following companies: Polymarket lacked adequate anti-fraud mechanisms; Crypto.com did not treat small-stakes users fairly; and Gemini's affiliated companies had not completed necessary regulatory reviews. The investigation indicated that all of these companies were believed to have business ties to the Trump family. Sources say that then-acting CFTC Chair Caroline Pham and her senior advisors intervened to help these companies obtain regulatory approval. By the end of 2025, two officials who raised concerns were administratively suspended and placed under internal investigation, and three other officials responsible for crypto enforcement faced similar treatment, without being given specific reasons. The report states that this created a "don't create trouble for the industry" signal within the CFTC. The CFTC significantly reduced its crypto enforcement efforts during the Trump era: during Biden's term, the agency initiated over 80 crypto enforcement actions, while during Trump's term, it initiated only two, both targeting individual operators rather than large corporations. In addition, Caroline Pham joined MoonPay, which has a partnership with Polymarket, after leaving the company; her former senior advisor, Brigitte Weyls, joined Gemini Titan as general counsel. Current CFTC Chairman Michael Selig has also previously served as corporate lawyer for several crypto companies. (Cointelegraph)

According to Huoxun Finance, a representative from the prediction market platform Polymarket stated that the security incident was caused by the leakage of an internal recharge configuration private key that had been in use for six years, resulting in some funds flowing to related addresses. The team has now completed private key rotation, reclaimed all production environment access, and will subsequently migrate all private keys to a Key Management Service (KMS), abandoning the traditional storage method. The platform and UMA contracts were not attacked, user funds are safe, and operations are unaffected.

According to Odaily Planet Daily, Josh, VP of Engineering and DeFi at prediction market Polymarket, stated in an article on the X platform that the security incident stemmed from the leakage of a 6-year-old private key. This private key was used for internal top-up configuration, which explains why some funds were sent to that address. Josh added that the Polymarket team has completed private key rotation, revoked all production environment permissions, and plans to migrate all private keys to a Key Management Service (KMS) instead of continuing to store them in the traditional way. Furthermore, Polymarket and its UMA contracts were not compromised, all user funds are safe, and the platform is functioning normally.

Odaily Planet Daily reports that Kalshi and Polymarket have lost a case to block gambling-related lawsuits brought against them by Nevada and Washington states. A panel of the U.S. Ninth Circuit Court of Appeals stated that federal derivatives regulation does not automatically protect prediction market platforms from enforcement of state gambling laws. The appeals court rejected the companies' request to halt the transfer of the dispute back to state courts, stating that Kalshi and Polymarket failed to prove their claim that the case fell under federal jurisdiction. This ruling exacerbates the legal debate over whether sports event contracts offered by prediction market companies are federally regulated derivatives or illegal gambling products under state law.

According to Huoxun Finance, the U.S. House Oversight Committee plans to investigate prediction market platforms, raising concerns that U.S. government employees may use insider information to profit from policy and national security events. Committee Chairman James Comer, a Republican representative from Kentucky, stated that the committee is reviewing internal records of the CEOs of Polymarket and Kalshi to examine whether government employees used insider information to profit from policy, geopolitical, and military operations. This could potentially push for legislation to prohibit members of Congress and government officials from participating in prediction markets. The prediction market is currently experiencing rapid growth, and both parties in Congress are increasing scrutiny of it, with allegations of national security risks, insider trading, and gambling-related issues.

Odaily Planet Daily reports that the U.S. Ninth Circuit Court of Appeals rejected Kalshi and Polymarket's request to allow Nevada and Washington states to proceed with their gambling-related cases against the two prediction market platforms, remanding the cases to state courts. The court held that the two companies failed to demonstrate that the cases should fall under federal jurisdiction. The platforms' claim of priority under the Commodity Exchange Act alone is insufficient to automatically establish federal jurisdiction. Kalshi and Polymarket had previously argued that contracts for sports, political, and other events are federally regulated derivatives under the CFTC, and that state governments have no jurisdiction under gambling laws. However, Nevada and Washington argued that such contracts constitute unlicensed gambling products. This ruling shows that the disagreement among U.S. courts regarding whether prediction markets fall under federally regulated swaps or illegal gambling products under state law is widening.

According to Huoxun Finance, the dispute between the US federal government and several states over the regulatory authority for prediction markets continues, with prediction market platforms such as Kalshi, Polymarket, Robinhood, and Coinbase continuing to increase their investment in the business. Currently, 17 states have challenged these platforms, with some arguing that sports event contracts constitute betting and should be regulated at the state level; the Commodity Futures Trading Commission (CFTC) maintains that event contracts are derivatives and subject to federal regulation. Congress has also intervened, with House Oversight and Government Reform Committee Chairman James Comer demanding that Kalshi and Polymarket submit documents related to their insider trading prevention mechanisms. Despite the uncertainty of the regulatory environment, the valuations of these platforms continue to climb: Kalshi's valuation reached $22 billion after its latest funding round, more than doubling from $11 billion in December of last year; Polymarket's valuation rose to $15 billion. Executives from companies such as Flutter Entertainment, DraftKings, and Robinhood have all stated they will continue to invest in prediction market businesses, believing that the related regulatory disputes will continue to evolve in the coming years.

According to Huoxun Finance, a U.S. federal appeals court ruled that enforcement lawsuits filed by Nevada and Washington states against prediction market platforms Kalshi and Polymarket can continue in state courts, rejecting the companies' requests to suspend the cases during their appeals. The court held that the two companies failed to demonstrate that the state court proceedings would cause irreparable harm, nor did they demonstrate a high probability of success for their claims of federal jurisdiction.

According to Huoxun Finance, Josh Stevens, VP of Engineering at Polymarket, disclosed that with the assistance of ZachXBT, BitcoinVN, and ChangeNOW, $164,000 in funds related to the Polymarket private key breach has been frozen, representing approximately 28.6% of the total transferred amount of $573,200. Josh stated that the incident did not affect Polymarket or the UMA smart contract, user funds are safe, and the platform is operating normally. The investigation revealed that the incident stemmed from the leakage of a private key that had existed for approximately six years. This private key was used for internal recharge configuration, causing funds to be continuously sent to affected addresses. The team is currently continuing to track the remaining stolen funds.
