Manifold
Play-money markets, anyone can create one.
Overview
Manifold is a play-money prediction market where anyone can create a question in seconds. Users trade with Mana, a virtual currency, which keeps the platform open globally and free of regulatory friction.
The result is a long tail of thousands of markets covering everything from AI benchmarks to personal bets between friends. It's the best venue for niche or experimental questions that real-money exchanges won't list.
Because there is no real money on the line, calibration on smaller markets is weaker than on Polymarket or Kalshi. Treat it as a forecasting playground rather than a trading venue.
