YeNo - User Guide

What is a prediction market?

Yes or No questions on real events — you trade against other users, not the house.

Peer-to-peer prices set by traders Live odds move with every trade Exit anytime sell before resolution

Each YeNo market is a Yes or No question about a real-world outcome — sports results, crypto prices, politics, and more. Buy the side you believe in. If you're right, your shares pay out when the market resolves. If you're wrong, they don't. You can also sell anytime before close to lock in profit or cut losses.

Peer pricingA Yes price of 56¢ means traders collectively think there's roughly a 56% chance — set by the order book, not by YeNo.
Order book matchingYour buy sits until someone sells the other side (or vice versa). Limit orders wait; market orders fill at the best available price.
Automatic payoutWhen a market resolves, winnings land in your wallet — no manual claim step.

Good to know: You're trading against other users, not the house. Prices move as new information arrives — watch the book before you enter.

Limit — price and quantity

Limit orders let you set an exact price and share count. Your order rests in the book until someone matches it — or you cancel. Best when you want a specific entry and don't need instant fill.

Resolution

Markets settle from official sources — not discretionary.

Markets settle automatically from official, pre-defined sources — league APIs, exchange feeds, and verified data providers. YeNo does not manually pick winners.

WinWinning shares pay out in USDC when the market resolves — credited to your wallet automatically.
LoseLosing shares are worth nothing at settlement.
Cancel / voidIf a market is cancelled, you get a full refund of your stake. You can also sell anytime before close to avoid waiting.

Before you trade: Open the Resolution tab on any market page to see the exact settlement rules and data source for that question.
