PoolDefy vs Polymarket
Prediction markets vs social prediction contests, different products with overlapping users.
Polymarket runs a continuous prediction market: anyone can buy or sell shares of an outcome at any time, and the price moves with order flow. PoolDefy runs prediction contests: a fixed entry fee, a fixed prize structure, and a deadline. Same idea, putting USDC behind a prediction, but two very different shapes. This page is a direct, fair comparison so you can pick the one that fits how you actually want to play.

FAQ
Is PoolDefy a prediction market like Polymarket?
Not exactly. Polymarket runs a continuous order book, you trade shares of a YES/NO outcome at a moving price. PoolDefy runs contests with a fixed entry fee, fixed prize structure, and a single resolution deadline. The DNA overlaps (USDC payouts, sports predictions), but PoolDefy settles from official sports data, not an on-chain oracle, and the user experience is closer to a fantasy contest than a market.
Can I get out of a position before the match ends on PoolDefy?
No. Contests settle once at the end. If you want intra-game liquidity (buy / sell anytime), Polymarket-style markets are a better fit. If you want lock-and-forget plus a clean payout, contests win.
Which has better odds, contests or markets?
Different question. A prediction market's spread is the cost of liquidity. A contest's 5% fee is the cost of running it. On a 60/40 outcome a contest typically pays out more to the winner than a market would (no spread to cross), but you give up the ability to trade in and out.
Does PoolDefy support political / crypto markets?
Right now we focus on sports. Binary markets on non-sports outcomes are on the roadmap.
