Prediction markets, embedded in your platform.

Polymarket and Kalshi proved operators are missing a vertical. Solex bends it into your casino or sportsbook — one iframe, your wallet, your players — the fastest way to capture the demand.

The fastest-scaling format in betting

The crowd already moved. The biggest operators followed.

In under two years, prediction markets went from a curiosity to a category measured in billions a month. Sports leads it — so it lands on the audience you already have. The question isn't whether to add prediction markets. It's who you build them with.

New to prediction markets?

Bet on what happens next.

A prediction market is a simple question with two answers — YES or NO. “Will Bitcoin close above $120k this year?” The price of YES is the crowd's live estimate of how likely it is. YES and NO always add up to $1, and a winning share pays out $1.

How to read a market

The price is the probability
“62% Yes” means the crowd's live estimate is about a 62% chance. The number is the odds.
YES and NO always sum to $1
Two outcomes, one dollar between them. Buy the side you believe.
A winning share pays $1
Buy Yes at 62¢ and if it happens you're paid $1 — a 38¢ profit per share.
The price moves as people trade
More buyers on a side push its price up — a live market for opinions.

It's a stock market for questions — instead of shares in a company, you buy shares in an outcome, and the share price is the chance it happens.

Any currency · fiat & crypto

Your players bet in their own money.

One integration accepts 80+ currencies — every major fiat and the crypto your players already hold. Each player bets in their native currency; a USD-equivalent is frozen on every bet, so your reporting still rolls up to a single number.

    currencies accepted from one integration — 56 fiat currencies and 27 crypto units.

  • Native

    every player bets, and is paid out, in their own currency — fiat or crypto.

  • Frozen

    a USD-equivalent is fixed on each bet, so cross-currency reporting still rolls up to one number.

  • 5-dp

    money runs at five-decimal precision — crypto sub-units round-trip without dust.

Self-service
declare or remove a native currency at any time — no ticket, no redeploy.

And when a real exchange rate can't be resolved, the bet is safely rejected — never quietly settled at a 1:1 rate.
