Polymarket launches five-minute crypto contracts paying $1 per share
Key Facts
Polymarket began rolling out five-minute cryptocurrency prediction contracts on its U.S. platform on October 28, 2026, according to a CoinDesk report. Traders choose whether a cryptocurrency’s price will finish the period above or below its starting price. The contract is a short-term binary wager on price direction over a set window. The platform pays $1 per share if the prediction is correct and nothing if it is wrong. The contracts cover Bitcoin, Ether, Solana and XRP. The launch puts the product in a U.S. market overseen by the Commodity Futures Trading Commission, while the platform faces an investigation into its compliance and customer protection controls.
Settlement relies on dollar-denominated CF Benchmarks indices, according to CoinDesk. The platform calculates an average of 60 index readings recorded during the contract window’s final 60 seconds. It compares that average with the price at the start of the five-minute period to determine whether the prediction got the direction right. This method ties payment to index readings at the end of the window rather than relying on a single reading at one moment. A correct prediction still pays $1 per share, while an incorrect one returns zero. That makes the contract’s mechanics straightforward, while leaving the outcome tied to price movements over a very short period.
The short contract window raises questions about how sensitive settlement is to price movements in the final minutes. An analyst at Nexo said smaller cryptocurrencies “may be more susceptible, particularly during quieter weekend trading.” The observation adds context to the choice to average readings from the final minute, without changing the contract’s stated payout rule. All 60 readings feed into the average used for settlement, while the wager remains based on comparing the end of the period with its start. Exposure to risk varies by cryptocurrency and the trading conditions cited by the analyst. Each contract offers a defined outcome per share: $1 if the prediction is correct, or nothing if it is wrong.
The contracts are part of Polymarket’s U.S. operations, run by QCX LLC as Polymarket US. Commodity Futures Trading Commission records show the company’s designation as a designated contract market has been listed as “Designated” since July 9, 2025. But that designation does not resolve the investigation reported by Reuters on October 27. The agency is examining whether Polymarket violated a 2022 enforcement agreement that required it to block U.S. users from its offshore platform, Reuters reported. The commission is also reviewing registration and customer protection procedures on the U.S. platform. The new contracts are launching as compliance and controls remain under scrutiny.
Some of the regulatory context dates to an earlier settlement with the operating company. On January 3, 2022, the Commodity Futures Trading Commission ordered Blockratize, Polymarket’s operator, to pay a $1.4 million civil penalty and wind down markets that did not comply with the law and regulations. The investigation reported by Reuters includes the question of whether the company breached the 2022 agreement concerning its offshore platform. In August 2026, the commission reminded entities under its regulation to provide clear and accurate pricing information for event contracts. It said the U.S.-style odds format used by sportsbooks could mislead participants about the nature of the product. The guidance comes amid broader regulatory scrutiny of how contracts are presented and understood by participants.
The Commodity Futures Trading Commission also emphasized designated contract markets’ responsibility to self-regulate the products they list. It said these markets must take proactive steps to oversee trading, taking into account each product’s characteristics. On August 12, 2026, the Division of Market Oversight issued guidance reminding those markets of their obligations when submitting self-certifications for market maker, liquidity, trading and incentive programs. The division cited procedural and substantive deficiencies in some filings. The commission also imposed a three-year trading ban on August 28 on a former government employee who misused nonpublic information to trade event contracts on prediction markets. These actions show the regulator’s broadening focus on oversight of products and trading in prediction markets.
