A Kalshi alternative and a Polymarket alternative

Hyperprice, Polymarket, and Kalshi side by side

All three let you buy a side that pays $1 a share if you are right. They differ in what you predict, how long a position runs, and how you fund it.

Polymarket and Kalshi are separate companies. Their markets, fees, and availability change, so check their own sites before you choose.

Which one fits what you want to trade

• News, sports, or elections. Hyperprice does not list event markets. That is Kalshi’s and Polymarket’s territory, where they are legal for you.
• A price call that settles in minutes. That is the Hyperprice format. Pick a listed market and a 1-, 5-, or 15-minute clock, buy UP or DOWN, then sell at the current share price or hold to the end.
• A bot or an API strategy. Hyperprice has no public or private trading API. Polymarket and Kalshi both publish one.
• USDT on BNB Smart Chain. Hyperprice takes USDT (BEP-20) deposits from $10. The app and this site are in 150 languages.

One Hyperprice round, start to finish

Take a 5-minute BTC round that opens at $84,010.50. You buy UP at 52¢ a share. If the round closes at $84,010.50 or higher, each UP share pays $1. If it closes lower, the shares pay $0. Before the countdown ends, you can sell at the share price shown in the app instead.

Who it is for

People who tap UP or DOWN in the app and want the chart to match settlement, not teams buying a private realtime API. Not anyone who cannot legally use a prediction market where they live.
