Prediction markets: odds on Bitcoin, economy and politics

Live odds on crypto, economy, politics and sports events from Polymarket, Kalshi and other platforms.

How prediction markets work

  • Price is probability

    Each answer trades between 0 and 1 dollar. If “Yes” costs 30 cents, the market puts the chance at 30%.

  • Traders set the odds

    The platform does not pick the number: it comes from supply and demand on both sides and moves with every piece of news.

  • Resolved by the official source

    Each market has rules and a resolution source, such as the Fed calendar or an official election result. Winners get 1 dollar per contract; losers get nothing.

  • BROBROK shows and compares

    We bring together markets from Polymarket, Kalshi and Limitless in one place so you can compare them. You cannot trade predictions through BROBROK.

Frequently asked questions

What is a prediction market?

A market where people trade contracts on the outcome of a future event, such as a rate decision or an election. The contract price works as the probability the market gives the event.

Why does the same question show different odds?

Each platform has its own participants, rules and liquidity. Comparing all 3 is exactly what this page is for.

How often do the odds update?

On every search and, on event pages, every minute, using the platform’s own prices.

Are prediction markets accurate?

They tend to react fast to news, but a 70% probability means that in 3 out of 10 similar cases the event does not happen. Use them as a gauge, not a certainty.

Can I bet through BROBROK?

No. BROBROK only shows the data. Each platform has its own country availability rules, and some do not accept residents of certain places.
