An opinion market is a live debate with two or more outcomes. You back an outcome by buying in, each outcome carries its own live price that moves as people trade, and when one outcome holds a dominant share of the money long enough, the market agrees and resolves.
This is an opinion market, not a prediction market. The winner is decided by where the crowd puts its money — not by a real-world result. There’s no referee waiting on an event to decide it; the market itself decides.

​
A debate, not a forecast

The question doesn’t need a real-world answer. It just needs sides people care about.
  • “Who had the better album this year?”
  • “Best villain of the decade?”
  • “Which brand wins the rivalry?”
Some debates are binary — two outcomes, for vs. against, team vs. team. Others are multi-outcome, with three or more sides for genuine multiple tribes, like best film or favourite to win the championship. Either way, you back the one you believe in.

​
Back an outcome

When you buy into an outcome, you build a position on that side. While the market is live you can add to it or cash out at the current price any time. Each outcome has its own live price, its own chart, its own top-holder leaderboard, and its own activity feed — so every side is effectively its own community inside the market.

​
Prices move as people trade

Buying an outcome pushes its price up; selling pushes it down. The more money flows onto a side, the higher its price climbs — so the chart is your best live read on which way the crowd is leaning. A price isn’t a percentage chance and there’s no fixed ceiling on it; it simply tracks where the money is going.

​
The market agrees

As money keeps flowing, one outcome can pull ahead and hold a dominant share of the market. Hold that lead long enough and the market agrees: the result locks in, and that outcome is the winner. No judge, no admin decision — the crowd’s money is the verdict.

​
A worked example

Mia backs Verstappen in a “Best F1 driver of the year” market. As more money flows onto his side, his price climbs and her position grows. Other drivers draw their own backers, but his side keeps the lead — and holds it long enough that the market agrees. The result locks in, and Mia goes on to claim her share of the prize the market has built up.
Outcomes are independent, so you can hold a position on more than one side at once if you want to hedge. When the market resolves, only your holdings on the winning side share in the payout — so spreading across sides spreads your stake thinner.
