What Are Event Contracts?

An event contract is the specific instrument you trade on a prediction market. Its structure is straightforward, but the nuances of how it works — what it measures, how it resolves, and what can go wrong — are worth understanding carefully before trading.

The Yes/No structure

Every event contract is built around a clearly defined question:

- Will the Federal Reserve cut interest rates at the May meeting?

- Will Bitcoin close above $100,000 by December 31?

- Will Team A win Sunday's game?

For every question, there are two complementary sides: Yes (the event occurs as defined) and No (the event does not occur as defined).

Each contract has a fixed maximum value of $1.00 if your side is correct, and settles at $0.00 if it isn't. You can buy either side depending on your view.

What "Yes" and "No" actually mean

This is where precision matters more than it first appears.

A Yes contract pays out only if the event happens exactly as specified in the contract's question — nothing more, nothing less. A No contract pays out if that precise condition fails to be met. This means No contracts often represent many possible paths to a payout: the event could fail to happen for any number of reasons, while Yes contracts typically depend on a single specific path.

This distinction matters for pricing. No contracts can sometimes trade at higher prices than people expect, simply because there are more ways for a defined condition to fail than to occur.

How it differs from other instruments

The binary structure is the defining characteristic. There is no open-ended valuation, no Greeks to manage, and no partial outcomes at settlement. The contract resolves one way or the other.

Settlement — and when it happens

When the event is officially resolved, trading stops and contracts settle automatically based on a predefined, authoritative data source named in the contract's terms. You don't need to take any action — your account is updated once the outcome is confirmed.

One important nuance: event timing and settlement timing are not always the same. A political election may occur on a specific date, but formal certification — which determines contract settlement — may come weeks or months later. Reviewing when settlement is expected, not just when the event occurs, is part of understanding the full terms of what you're holding.

Edge cases and non-standard outcomes

Not all events resolve cleanly into a clear Yes or No. Events can be tied, postponed, cancelled, or resolved in ways that fall outside the expected outcome structure. When this happens, the exchange's predefined rules govern how settlement is handled — some contracts may settle at a partial value such as $0.50, others may be resolved based on the most reasonable available interpretation.

These situations are not common, but they are real. Reading how a contract defines resolution — including how it handles edge cases — is part of due diligence before entering a position.

You can trade before settlement

Event contracts don't have to be held until the event resolves. You can buy a position and sell it later as the price moves, realizing a gain or limiting a loss based on the change in the market's probability estimate — without waiting for the binary outcome.

That said, the ability to exit is not guaranteed. Liquidity varies across contracts and can change as events approach resolution. Many experienced participants enter positions with the assumption that they may need to hold through settlement, even when early exit is their intention.

The bottom line

Event contracts are simple in structure but precise in practice. Understanding what the contract is literally measuring, when it settles, and how edge cases are handled is foundational. Many early losses in event contract trading come not from incorrect predictions, but from misunderstanding the mechanics of the instrument itself.
