Polymarket Launches Five-Minute Crypto Prediction Markets in the US
United States.- 29 October 2026 | www.zonadeazar.com Polymarket has announced the introduction of five-minute cryptocurrency prediction contracts on its US application, expanding its range of short-duration financial event markets.
The launch, announced on 27 October 2026, allows eligible users to trade contracts linked to the price movements of Bitcoin (BTC), Ethereum (ETH), Solana (SOL) and XRP.
The development represents another step in Polymarket’s US expansion and intensifies competition with Kalshi, another major prediction market platform regulated by the Commodity Futures Trading Commission (CFTC).
Four Cryptocurrencies Available
The new product covers four major digital assets:
- Bitcoin (BTC).
- Ethereum (ETH).
- Solana (SOL).
- XRP.
Each contract allows traders to predict whether a cryptocurrency’s price will finish above or below its starting level after five minutes.
Unlike some conventional financial instruments, participants do not need to forecast an exact price or percentage movement.
The outcome depends solely on the direction of the price movement during the specified interval.
How Five-Minute Contracts Work
Each market offers two possible outcomes:
- Up: the asset’s price will finish above its starting level.
- Down: the asset’s price will finish below its starting level.
Contracts predicting the correct outcome settle at US$1 per contract, while unsuccessful positions expire without a payout.
For example, a trader purchasing a contract for US$0.60 would receive US$1 if the prediction proves correct.
This would represent a gross profit of US$0.40 before applicable fees.
If the prediction is incorrect, the trader loses the US$0.60 paid for the contract.
Up to 288 Settlement Windows per Day
The five-minute format creates multiple trading opportunities throughout the day.
Each hour contains 12 five-minute intervals, equivalent to a maximum of 288 settlement windows per asset daily.
This frequency distinguishes the product from longer-duration financial contracts.
However, it also increases the importance of liquidity, execution speed and transaction costs.
Rapid price movements can change the outcome of a position within seconds.
CF Benchmarks Provides Settlement Prices
Contracts offered through Polymarket’s US application use pricing information provided by CF Benchmarks, a specialist provider of digital asset reference rates.
Settlement outcomes are determined according to this pricing methodology.
If the opening and closing prices are equal, the contract settles in favour of Up.
The use of a predefined price reference is intended to establish transparent settlement criteria.
Nevertheless, traders should be aware that settlement prices may differ from quotations displayed on individual cryptocurrency exchanges.
Trading Fees and Transaction Costs
Polymarket applies fees to traders executing orders against available market liquidity.
These charges, known as taker fees, are calculated separately from the bid-ask spread.
Consequently, the final return on a position depends on several factors:
- The contract’s purchase price.
- Applicable trading fees.
- The bid-ask spread.
- Available market liquidity.
- The outcome determined by the reference pricing system.
The company has not published profitability forecasts for the new contracts.
Polymarket Expands Its Cryptocurrency Offering
The launch forms part of a wider strategy involving cryptocurrency prediction products with different settlement periods.
On 15 October 2026, Polymarket introduced 15-minute, hourly and daily contracts for Ethereum, Solana and XRP in the United States.
The company had previously launched five-minute Bitcoin markets on its international platform in February 2026.
The latest release therefore represents an expansion of the US product range rather than the first introduction of five-minute cryptocurrency markets across Polymarket globally.
Differences From the International Platform
Polymarket maintains separate arrangements for its US application and international operations.
While the new American contracts use CF Benchmarks pricing, the international platform has employed Chainlink-based reference mechanisms for certain short-duration markets.
These include time-weighted average prices, commonly referred to as TWAP.
Different pricing sources and methodologies may produce different outcomes during periods of rapid market movement.
For this reason, settlement rules are an important consideration for traders.
Competition With Kalshi Intensifies
The launch positions Polymarket more directly against Kalshi in the short-duration financial event contract segment.
Kalshi already offers cryptocurrency price prediction markets, including products with 15-minute intervals.
By introducing five-minute contracts, Polymarket provides an alternative with an even shorter settlement period.
The competition reflects the expansion of prediction markets into products linked to financial assets and cryptocurrencies.
Both companies are seeking to attract users interested in trading contracts based on future outcomes.
Polymarket’s Return to the United States
Polymarket’s US expansion followed its acquisition of QCX, a company providing derivatives exchange and clearing infrastructure.
The transaction was announced in July 2025 and provided a regulated framework for the company’s return to the American market.
Previously, in January 2022, the CFTC imposed a US$1.4 million civil penalty on Polymarket for operating an unregistered derivatives trading facility.
The company’s US application now operates separately from its international platform through federally regulated infrastructure.
Prediction Markets Face Regulatory Scrutiny
The expansion of Polymarket and Kalshi comes amid regulatory debates concerning the classification of event contracts.
The CFTC supervises certain financial markets and derivative instruments, while several US states have challenged the legality of particular products, especially those linked to sporting events.
Cryptocurrency prediction contracts form part of a broader commercial expansion towards financial products based on short-term price movements.
Federal oversight does not automatically resolve every regulatory dispute surrounding these platforms.
Industry Impact and Next Steps
The introduction of five-minute cryptocurrency markets expands the trading options available to eligible Polymarket users in the United States.
The launch also increases competition between prediction market platforms and other providers of cryptocurrency-related financial products.
However, the company has not disclosed initial trading volumes, active user figures or revenue forecasts for the new contracts.
Their commercial performance will depend on sustained participation, market liquidity and transaction costs.
Through this expansion, Polymarket strengthens its presence in the US market and positions short-duration contracts as another offering within the growing financial prediction market ecosystem.
