FAQ

Q: What prediction markets do you cover?
A: We cover the four major platforms: Polymarket (crypto-based, real money), Kalshi (US-regulated, real money), Metaculus (community forecasting, no trading), and Manifold Markets (play money). We clearly label which are real-money vs play-money.

Q: How accurate are prediction market odds?
A: Prediction markets aggregate the wisdom of thousands of traders and have been shown to be more accurate than individual experts or polls. However, they can be wrong — especially for low-volume markets or events with limited information. Always treat odds as estimates, not certainties.

Q: How does this compare to checking Polymarket directly?
A: Polymarket only shows its own odds. If Kalshi has a different price for the same event, you won't see it on Polymarket. Our checker shows all platforms side by side, calculates consensus, and flags arbitrage — saving you from manually checking 4 websites.

Q: Can I trade directly through this agent?
A: No. This agent helps you research and compare odds. To trade, you'll need to visit the respective platform. We provide direct links to each market so you can act quickly.
