Pick a market
Politics, sports, crypto, culture, tech — every market resolves to a clear yes or no with a public source like FIFA, Coinbase, or NBER.
02
Take a position
Buy YES or NO shares at the current price (in cents). Prices move with the crowd's belief; your edge is finding mispriced ones.
03
Cash out when right
Winning shares pay 100¢ at resolution. Sell early once the market moves your way, or hold to expiry — whichever you prefer.
