Frequently Asked Questions

Prediction markets allow participants to trade contracts tied to defined outcomes of future events. Contract prices can reflect the market's current view of the probability of an outcome, subject to the contract's pricing structure and rules.

The table displays the event contracts with the highest trading activity through Interactive Brokers for the period and market universe specified on the page. Rankings can change as market participation changes.

For a binary contract, price may be interpreted as a market-implied probability when expressed on a 0 to 1 or 0% to 100% scale. It is not a certainty, and fees, liquidity, spreads and contract specifications can affect interpretation.

Settlement depends on the contract's defined rules, expiration terms and named resolution source. Review the full contract specifications before trading, including what outcome qualifies, when trading ends and how disputes or revisions are handled.

Risks include loss of the amount committed, rapid price changes, limited liquidity, wide spreads, event ambiguity, settlement or resolution risk and regulatory or product-availability constraints.

Availability varies by client location, account eligibility, permissions, venue and applicable rules. Clients should confirm access and review the relevant disclosures within their Interactive Brokers account.
