Market Types
TxFlow lists prediction markets with two outcome structures: binary (two outcomes) and category (several outcomes, one winner).
Binary markets
Two outcomes, YES or NO:
Will BTC be above $100,000 at 08:00 UTC on September 30?
Buy YES if you think the condition will be met, NO if you think it will not. At resolution one side settles at $1 and the other at $0.
Crypto up / down markets
Some crypto markets ask whether an asset finishes above or below a reference price. The reference price, observation time, price source, and resolution conditions are all shown in that market's Resolution Rules — read them before trading, since they differ per market.
Category markets
Several possible outcomes, exactly one of which wins:
Which team will win the tournament?
| Outcome | YES price |
|---|---|
| Team A | $0.40 |
| Team B | $0.30 |
| Team C | $0.20 |
| Team D | $0.10 |
YES prices across all outcomes sum to roughly $1 because only one can win. If Team A wins, Team A YES settles at $1 and every other YES settles at $0.
Trading a single outcome
Each outcome in a category market can be traded from either side:
- Buy YES on Team A — you win if Team A is the winning outcome.
- Buy NO on Team A — you win if any other valid outcome wins.
Categories
TxFlow may list markets across crypto, sports, and other event categories. The available set changes over time. Evaluate each market on its own Resolution Rules rather than on its category.
