NBA prediction markets have exploded in volume since Kalshi launched regulated sports trading in 2024. You can now trade everything from game winners to player performance markets — all at regulated, legal odds.

## What NBA Markets Are Available on Kalshi?

Kalshi lists NBA markets across several categories:

- **Game winners** — moneyline-style binary contracts
- **Championship markets** — who wins the NBA Finals
- **Player props** — points, assists, rebounds thresholds
- **Season awards** — MVP, Rookie of the Year, Coach of the Year

## How NBA Prediction Market Prices Work

Each contract is priced in cents, where 1 cent = 1% implied probability. A contract at 65 cents means the market implies a 65% chance of that outcome.

To convert to American odds: a 65% implied probability = **-186** in American odds format. Use our [free Probability Converter](https://predictionmarketspicks.com/tools/probability-converter) to convert instantly.
