CFTC monitors prediction markets ahead of 2026 midterm elections

The Commodity Futures Trading Commission (CFTC) announced on October 23, 2026, that it is strengthening its surveillance of prediction markets, fearing manipulations ahead of the U.S. midterm elections on November 5. This decision, revealed by its chairman Michael Selig, could weigh on tokens linked to these platforms as regulators intensify their control over crypto derivatives. Context Prediction markets, which allow betting on events such as elections or economic indicators, have gained popularity thanks to blockchain. Platforms like Polymarket or Kalshi, which use derivative contracts, attract hundreds of millions of dollars in commitments. The CFTC, responsible for regulating these products in the United States, had already sanctioned abuses in 2025 and 2026, notably manipulations related to insider information. Meanwhile, the DeFi sector shows signs of liquidity concentration: on October 24, the DEX Thena on BNB Chain displayed a TVL of 1.59 million dollars, with 89.1% of holders concentrated in the top 10, according to platform data. This surveillance comes amid increased regulatory tensions. The CFTC recently published guidelines on contracts linked to personal conduct, highlighting the risks of manipulation. However, no concrete measures have yet been announced for the 2026 elections, leaving uncertainty about the extent of the upcoming controls. The Facts On October 23, 2026, Michael Selig, chairman of the CFTC, stated in an interview with Bloomberg that the agency was actively monitoring prediction markets to detect potential manipulations before the midterm elections. No specific platform was mentioned, but Dune Analytics data, dated October 18, reveals that Kalshi and Polymarket then concentrated 250 million dollars in open commitments on the elections, including 210 million for Kalshi (84% of the total). Over the election period, Kalshi recorded a notional volume of 353 million dollars, compared to 160 million for Polymarket, according to Dune. Cash volumes amounted to 147 million and 77 million, respectively. Polymarket had 24,930 active wallets on the elections, with a median position of 14 dollars. The top 100 wallets represented 56% of the total value of positions. The CFTC recalled two recent cases: that of Gabriel Perez, a former White House collaborator, sentenced in August 2026 to repay 107,539 dollars in illicit profits, and that of former Representative George Santos, sanctioned in July for manipulating contracts related to his presence at the State of the Union address. No updated figures were communicated regarding volumes or open positions as of October 24. Data from CryptoScore Pro, on the same date, show a marked decline in the REP (Augur) token, with a price of 0.7362 dollars (-12.54% over 24 hours) and a TVL of 1.61 million dollars. The Crypto Fear & Greed index remains neutral (51/100). Understanding Key Concepts Prediction Market A prediction market is a platform where users bet on the outcome of future events, such as elections or sporting results. These bets often take the form of derivative contracts, whose value depends on an external outcome. For example, a user can buy a contract that will pay 1 dollar if candidate X wins the election, and 0 dollars otherwise. These markets are used to aggregate information and estimate probabilities, but they can also be manipulated, which explains the attention from regulators. TVL (Total Value Locked) TVL measures the total value of assets deposited in a DeFi protocol, such as a decentralized exchange (DEX) or a lending platform. It reflects available liquidity and user confidence. For example, a TVL of 1.59 million dollars on Thena means that users have locked this amount in assets. A high concentration of holders (such as 89.1% in the top 10) can indicate a risk of manipulation or massive withdrawal. Derivative Contract A derivative contract is a financial instrument whose value depends on an underlying asset (such as a stock, a commodity, or an election result). In prediction markets, these contracts allow for speculation on events without owning the asset itself. For example, a contract on the outcome of an election can be traded even before the vote takes place. The CFTC regulates these products in the United States to prevent abuses, such as price manipulation or the use of insider information. Open interest Open interest represents the total number of derivative contracts in circulation that have not yet been settled. It indicates the scale of commitments in a market. For example, an open interest of 250 million dollars on elections means that investors have bet this amount on contracts linked to the results. An increase in open interest can signal growing interest, but also an increased risk of volatility if positions are liquidated abruptly. Analysis: what is at stake Increased surveillance of prediction markets by the CFTC introduces a regulatory dynamic that could redefine the sector's balances. From an economic point of view, these platforms rely on supply and demand mechanisms where liquidity is often concentrated: according to Dune data as of October 18, 2026, 56% of the value of positions on Polymarket were held by the top 100 wallets. This concentration exposes associated tokens, such as Augur's REP, to brutal price movements in the event of a massive withdrawal of liquidity, as evidenced by its 35% drop over seven days (CryptoScore Pro, October 24, 2026). Investor incentives could also evolve. Stricter regulation could deter institutional players, reducing volumes and market depth, while platforms could pass compliance costs on to users via increased fees. Conversely, a clarification of the rules could attract capital seeking legal security, as suggested by the relative stability of BTC and ETH over the same period (respectively -0.93% and -1.98% over seven days). Several scenarios are emerging. In the event of regulatory tightening, American platforms such as Kalshi (84% of open positions on…
