Disclaimer

In short: dino.markets is a data service for sports prediction markets. We publish prices, matches, and computed signals from Kalshi and Polymarket. We do not give advice, place trades, or hold your money. Please read this page before you rely on anything we publish.

This is not financial advice

Nothing on dino.markets or in our API is financial, investment, legal, or tax advice, and nothing here is a recommendation to buy, sell, or hold any contract. We report numbers such as prices, fillable size, and the fee-adjusted gap between two venues. We never tell you what will happen or what you should do. Decisions about your own capital are yours alone. If you want advice, speak with a licensed professional.

We are a data provider

We publish data through an API. We do not place trades, route orders, custody funds, or act as a broker, dealer, exchange, or adviser. You keep your own accounts and capital on Kalshi and Polymarket, and you execute every trade yourself.

A signal describes a moment in time

When we surface a cross-venue gap, we are describing two prices at one moment, along with the fillable size and the edge after fees. Markets move. A gap can shrink or close before you act, the size you see may not fill, and your two trades can land at different times and prices. We make no promise about results, profit, or how any market resolves.

Data can be delayed or wrong

Free and anonymous access is delayed. Even real-time data can arrive late, incomplete, or wrong because of an upstream venue issue, a network problem, or a bug on our side. Feed health shows as live, degraded, or stale so your code can react, and you should still build your own checks before you put capital at risk.

Venues settle on their own rules

Kalshi and Polymarket are separate venues with their own contracts, settlement rules, fees, currencies, and resolution sources. The same game can resolve differently across them. We score each match for settlement-rule confidence and filter low-confidence matches out of your feed, and the venues’ own rules always govern how a contract pays out.

Prediction markets carry risk

Trading on prediction markets can lose money, up to and including your full stake. Only commit money you can afford to lose. Past results and our historical tape do not predict future outcomes.

Eligibility and the law are your responsibility

Prediction markets are regulated differently around the world, and some are restricted or unavailable in certain places, including parts of the United States. You are responsible for confirming that you are eligible to use Kalshi and Polymarket where you live, and for following every law and venue rule that applies to you.
