Create your account
Open the app and tap Create account. Sign up with your email and a password, or use a sign-in link sent to your email.
You must be 18 or older, and live trading isn't available where Polymarket doesn't allow it, including the United States.
Start on paper
Every account comes with a Paper account holding $1,000 of practice money. It uses live Polymarket prices and charges the same fees, so your results are realistic, but no real money moves.
You can reset the paper balance any time from the app.
Pick your market
Open Controls to choose the coin (Bitcoin, Ethereum or Solana) and the round length (5 minutes, 15 minutes or 4 hours). Each account remembers its own choice.
Make your first trade
On Trade, tap Up if you think the price will finish at or above the Price to beat, or Down if you think it will finish below. Each button shows what you'd make if it wins, after fees.
When it fills you'll see Filled, and the bet appears on the round card until the round ends.
Add the app to your Home Screen
On iPhone, open the app in Safari, tap Share, then Add to Home Screen. It opens full screen like a normal app, and phone notifications only work from the Home Screen app.
