An independent beginner's guide to Polymarket — the world's largest prediction market platform. Sign up, fund your account, place your first trade, and cash out, explained in plain language.
A prediction market lets you buy and sell shares in the outcome of real-world events — elections, sports results, economic data, even weather. If your prediction is right, your shares pay out. Because prices move with supply and demand, the current price doubles as the crowd's best guess at the probability of the event happening.
Every market has two sides. "Yes" shares pay $1 if the event happens; "No" shares pay $1 if it doesn't. You buy whichever side you believe in.
A "Yes" price of 62¢ means the market believes there's a 62% chance the event happens. Prices move as traders react to news.
You don't have to wait for the outcome. Sell your shares early to lock in profit, or cut losses if the odds turn against you.
When the event concludes, the market resolves and winning shares redeem at $1.00 each. Losing shares expire worthless.
From zero to your first trade — the full journey, simplified.
