What Are 15-Minute Prediction Markets?

15-minute prediction markets are short-duration event contracts that let participants take positions on whether an asset’s reference price will meet a specified condition within a 15-minute period. Available markets may include Bitcoin, Ethereum, gold, and other assets. This guide explains how 15-minute prediction markets work, how contracts are priced and settled, the risks involved, and where to find 15-minute prediction markets on Public.

How do 15-minute prediction markets work?

15-minute prediction markets are event contracts tied to whether an asset’s price meets a specified condition at the end of a 15-minute period. Unlike buying the underlying asset, these contracts settle based on a defined outcome. Each market has its own target price, expiration time, and settlement rules. On Public, users can view available 15-minute prediction markets, including those tied to cryptocurrencies, commodities, and foreign exchange rates.

1. Explore available markets. View active 15-minute prediction markets on Public, including event contracts tied to Bitcoin, Ethereum, and other supported assets.
2. Understand the contract terms. Review the target price, expiration time, settlement methodology, and official price source used to determine the outcome.
3. Understand Yes and No outcomes. Each contract specifies the conditions under which a Yes or No position settles in favor of its holder.
4. Review contract prices. Prices reflect market activity and can be interpreted as market-implied probabilities, but they do not guarantee an outcome.
5. Understand expiration and settlement. Contract prices may fluctuate before expiration. Positions may be closed early, subject to market liquidity. Contracts held through expiration settle according to their specified rules.

15-Minute prediction market example

Suppose a Bitcoin 15-minute prediction market has a target price of $80,000. The contract specifies that the Yes outcome occurs if Bitcoin’s official settlement price is at or above $80,000 when the 15-minute window ends.

• If the settlement price is $80,100: The Yes outcome occurs.
• If the settlement price is $79,900: The No outcome occurs.

On Public, the outcome of each 15-minute event contract is determined by its specific settlement rules. The official settlement price may be calculated using multiple reference-index readings rather than the last traded price displayed on a cryptocurrency exchange.

(This hypothetical example is for educational purposes only and does not represent an actual event contract or a prediction of Bitcoin’s price.)

How are 15-minute contract prices and payouts calculated?

On Public, 15-minute prediction market contracts are generally priced between $0.01 and $0.99. Each contract settles at $1.00 if the specified outcome occurs or $0.00 if it does not.

For example, a Yes contract priced at $0.65 represents an approximately 65% market-implied probability of that outcome. However, market-implied probabilities reflect trading activity and are not guarantees or forecasts. Actual execution prices depend on available bids, asks, spreads, and market liquidity.

Example: 15-minute prediction market payout

Suppose one event contract is purchased for $0.60 and held through resolution:

• If the contract settles at $1.00: The resulting profit is $0.40, excluding fees.
• If the contract settles at $0.00: The resulting loss is $0.60, excluding fees.

The maximum potential loss for a fully paid long contract is the purchase price plus applicable fees.

Fees and costs: Event contract trading on Public may involve applicable fees and charges that affect net returns. Review Public’s current fee schedule and order preview for applicable costs. Frequent trading can result in accumulated transaction costs.

Are 15-minute prediction markets open 24/7?

Yes, supported 15-minute prediction markets on Public are available for trading 24 hours a day, 7 days a week, including weekends and holidays, subject to market availability, trading halts, and applicable restrictions.

Unlike traditional U.S. stock markets, which operate during scheduled trading hours, 15-minute prediction markets can operate around the clock. Each event contract covers a specific 15-minute window, with new markets opening as previous windows close. Once a contract expires, it is no longer available for trading and settles according to its predefined rules.

What are the risks of trading 15-minute prediction markets?

15-minute prediction markets involve significant financial risks due to their short duration, rapidly changing prices, and outcome-based settlement. Key risks include:

• Rapid price fluctuations: Contract prices can change substantially within minutes as market conditions and implied probabilities shift.
• Risk of losing the entire investment: Contracts that settle at $0 result in a complete loss of the purchase price, plus applicable fees.
• Liquidity and bid-ask spreads: Limited market liquidity or wide spreads may make it difficult to close a position before expiration or result in unfavorable execution prices.
• Settlement price differences: Official contract outcomes are determined using specified reference prices or indices, which may differ from prices displayed on cryptocurrency exchanges or other financial platforms.
• Trading fees and costs: Frequent transactions can result in accumulated fees and charges that affect overall returns, including when trades are executed through automated strategies.

Because 15-minute event contracts expire quickly, market conditions can change before a position can be closed. Understanding each contract’s settlement rules, pricing, liquidity, and potential losses is important when evaluating these markets.

On Public.com, supported prediction markets can be monitored with Public AI Agents, and eligible developers can use the Public API and Python SDK for programmatic workflows. Automation does not eliminate trading risk, order-execution risk, or fees.
