How outcomes settle

A contract is a question with two clear answers.

Most markets here are binary: a clearly defined yes or no question. Each contract resolves to one dollar if yes and zero if no. The price you pay between 1 and 99 cents is the market's live read on the odds.

Settlement follows a written rule defined before trading: the named source, the date, and how edge cases are handled. Read that rule before you trade; it is the contract.

Resolution sources and timing differ by platform and market. Always check the specific market's rules, not the headline.

Step by step

How a trade actually works.

1
Read the resolution rule
Find the exact source and date the market uses to decide, and how it treats edge cases. This rule is the contract.
2
Check your eligibility
Confirm the platform is legally available where you live and that you meet the age and verification rules.
3
Read the price as a probability
A 64 cent contract implies a 64 percent chance. It is an estimate, not a forecast, and it moves as others trade.
4
Size the position honestly
Decide your maximum loss before you buy. Account for fees and the spread, which quietly reduce real returns.
5
Place and monitor
You can usually sell before resolution at the current price to lock in or cut a loss, if there is enough liquidity.
6
Settlement and payout
When the event resolves, winning contracts pay one dollar and losing ones pay nothing. Withdrawal timing depends on the platform.
Before you trade

Five questions worth asking first.

If you cannot answer these for a specific market, you do not yet understand what you would be buying.

What exact source and date decides this market, and who adjudicates a dispute?

Is there enough liquidity for me to exit at a fair price before resolution?

What are the all-in costs, fee, spread, deposit and withdrawal, on a trade this size?

Is this platform legally available to me, and am I within its age and verification rules?

What is the most I am willing to lose here, and have I decided that before buying?

FAQ

The questions readers keep asking.

What is a geopolitical prediction market?

A geopolitical prediction market is a market in binary contracts on a defined world event, such as whether a leader leaves office, whether a treaty is signed, or whether a country joins an alliance by a set date. Each contract settles at one dollar if the outcome happens and zero if it does not, and the price between one cent and ninety nine cents reads as the implied probability. This is general information, not advice.

How does a world event market settle?

It settles against the resolution source named in the contract rules, usually an official announcement or a defined authoritative source once the event is confirmed. Because world events are often ambiguous, the rules must define exactly what counts as the event happening, the timing, and how disputes are handled, so read them closely before trading.

Are war and terrorism contracts allowed on United States venues?

As of June 2026 the Commodity Futures Trading Commission has proposed a rule that would treat event contracts involving war, terrorism, assassination, gaming, or activity unlawful under federal or state law as a category contrary to the public interest, and therefore not listable on registered venues. The proposal was open for comment, with comments due in late July 2026, so this is a proposed position, not a final rule. This is general information, not legal advice.

Why are world event markets harder to resolve?

World events are often messy and contested, so the hardest part is defining exactly what counts as the event happening and when. A poorly worded contract can leave the outcome genuinely arguable, which is why the resolution clause matters as much as your view of the event.

Can I exit a geopolitics position before it resolves?

On most venues you can sell your position back into the market at the current price before the event resolves, subject to enough liquidity, or hold to settlement where a correct contract pays one dollar and an incorrect one pays nothing.
