CFTC launches a comprehensive investigation into Polymarket, including allegations of wash trading, affecting the Robinhood event contract ecosystem; Nasdaq distributes TotalView market data on-chain through Pyth Network for the first time

According to BBX data, the prediction market faced a dual attack yesterday, with traditional exchange infrastructure accelerating its on-chain transition. The core dynamics are as follows:The prediction market/event contract ecosystem where Robinhood Markets, Inc. (NASDAQ: $HOOD) operates suffered a dual regulatory blow yesterday: first, the U.S. Commodity Futures Trading Commission (CFTC) has launched a comprehensive investigation into Polymarket (privately held), covering its social media activities and suspected wash trading behaviors; second, a Michigan court ruled to prohibit Kalshi (privately held) from offering sports betting services to residents in Michigan. Although these two incidents directly target Polymarket and Kalshi, their strategic importance to Robinhood cannot be ignored—Robinhood provides event contract products linked to KalshiEx LLC or ForecastEx LLC through its subsidiary Robinhood Derivatives LLC, making it the largest distribution channel for prediction markets among regulated brokers in the U.S. The CFTC's escalation of enforcement investigations into similar platforms will directly impact Robinhood's event contract business compliance framework and product expansion speed; in June, the average daily trading volume in this sector reached a historic record.Nasdaq, Inc. (NASDAQ: $NDAQ) announced yesterday that it has chosen Pyth Network (on-chain price oracle protocol) as its on-chain distribution partner for TotalView (Nasdaq's full market depth data product), marking the first time Nasdaq has integrated its core institutional-level market data into a blockchain network—TotalView provides full-level buy and sell quotes and transaction data for the U.S. stock market, historically only available to traditional financial institutions (subscription-based); on-chain distribution means that DeFi protocols, decentralized exchanges, and smart contracts can now access Nasdaq-level real-time equity market data as an on-chain pricing basis for the first time. The Pyth Network token (PYTH) subsequently rose by over 6%, with the market interpreting this as a historic fusion point between traditional securities market infrastructure and decentralized finance.

SBI Holdings acquires Bitbank for $289 million, creating Japan's largest cryptocurrency exchange; bipartisan U.S. senators urge CFTC to investigate Polymarket's "deceptive marketing."

According to BBX data, last weekend Japan's largest financial group completed the most important cryptocurrency acquisition, and U.S. bipartisan senators launched a new regulatory offensive against prediction market platforms. The core developments are as follows:SBI Holdings, Inc. (Tokyo Stock Exchange: 8473) announced the acquisition of the Japanese cryptocurrency exchange Bitbank (privately held) for approximately $289 million. After the transaction is completed, SBI's cryptocurrency business will surpass all competitors, creating Japan's largest cryptocurrency exchange. SBI Holdings is one of Japan's largest independent financial services groups, already owning cryptocurrency-friendly network bank SBI Shinsei Bank, cryptocurrency asset custodian SBI Digital Asset Holdings, and multiple Bitcoin mining and cryptocurrency venture capital investments. Bitbank is one of Japan's largest spot BTC exchanges and holds an official cryptocurrency exchange license from the Financial Services Agency (FSA) of Japan. This acquisition marks a shift for traditional Japanese financial institutions from "strategic trial" in the cryptocurrency sector to "scale acquisition dominance," alongside the joint stablecoin plan of the three major banks: Mitsubishi UFJ ($MUFG), Sumitomo Mitsui ($SMFG), and Mizuho ($MFG) (targeting March 2027), forming the most intensive wave of cryptocurrency layout in Japan's financial industry by 2026.U.S. Senators John Curtis (Republican, Utah) and Adam Schiff (Democrat, California) reported on June 28 that they jointly sent a letter to the CFTC, urging it to conduct a formal investigation into the prediction market platform Polymarket (privately held), citing a "concerning" investigative report regarding Polymarket's "deceptive marketing" practices, which accused it of systematic misleading in user acquisition and risk disclosure. This is the third regulatory offensive against prediction market platforms initiated by Congress this year (previously, the House Oversight Committee launched an insider trading investigation on May 22); the two senators come from different parties, which is significant. For Robinhood Markets, Inc. (NASDAQ: $HOOD), this investigation poses indirect pressure—Robinhood's prediction market/event contract business (which achieved a record daily trading volume in June) faces the same regulatory qualitative disputes as Polymarket; however, Robinhood's defensive advantage lies in its ongoing application for a CFTC Designated Contract Market (DCM) license, providing a clearer compliance path compared to Polymarket.

Polymarket's annual revenue exceeds 1 billion dollars

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.
