Kalshi and Polymarket promo codes for NBA traders
Both major prediction markets run new-user offers. This page lists the current Kalshi and Polymarket offers Courtside links to, how to claim them, and what to check before you deposit. Offers change often, so the codes below load live from Courtside rather than being written into the page.
Kalshi
CFTC-regulated exchange that lists a moneyline, spread and total contract for every NBA game, plus season futures.
Polymarket
Prediction market with NBA game and futures contracts, often priced a few cents away from Kalshi on the same game.
New users only. 18+. Terms apply. Courtside may earn a commission.
Before you claim an offer
- Offers are for new accounts only and usually require identity verification and a first deposit or trade.
- Bonus credit can carry conditions, such as a minimum trade amount or an expiry date. Read the venue’s own terms.
- Availability depends on where you live. Some states restrict sports contracts on prediction markets.
- You must be 18 or older, or older where local rules require it.
How Courtside makes money from these links
These links are sponsored. If you open an account through them, Courtside may earn a referral commission. That does not change the prices, fair values or price gaps shown on the board, which come from the same order-book data for every venue.
