Promotions on prediction market apps look more like brokerage offers than casino bonuses, which makes sense given how these platforms work. Instead of deposit matches tied to heavy playthrough, you'll typically see sign-up trading credits, deposit bonuses, fee rebates, and "risk-free" first-trade offers that refund a losing position up to a set amount. The value comes down to how the credit is applied and whether it's actual withdrawable funds or balance you have to trade through first—details that vary a lot from one platform to the next.
This section tracks the current offers from the major prediction market apps, with clear breakdowns of what each promotion is really worth and how to claim it. Browse by platform to see what Kalshi, OG, Polymarket, and others are running right now.

Prediction market platforms are competing aggressively for new users, and that competition has translated into genuine value for traders willing to shop around. Welcome bonuses, promo codes, referral programs, and ongoing incentive structures give new and existing users real opportunities to boost their starting position. This page is your hub for the latest prediction market promotions — what is currently available, how to claim it, and what to watch out for in the fine print.
Prediction market promotions differ meaningfully from traditional sportsbook bonuses, so it is worth understanding what you are actually getting before you sign up. Here is a breakdown of the most common offer types you will encounter.
The most common structure in prediction markets is a trade-and-get promotion. Rather than requiring a large deposit match, the platform credits your account with a bonus after you complete a minimum level of trading activity. Kalshi’s current welcome offer follows this model — new users who complete a qualifying amount of trading receive a bonus credited to their account, regardless of whether their initial trades win or lose. This is a trader-friendly structure because the bonus is not contingent on a winning outcome.
Most prediction market platforms run ongoing referral programs that reward both the person making the referral and the new user being referred. Kalshi’s refer-a-friend program credits bonuses to both parties once the new user completes the required trading activity. If you already have an account on a platform, the referral program is often the best ongoing source of bonus value outside of the sign-up offer itself.
Active traders on Kalshi can participate in volume and liquidity incentive programs that reward users for contributing to market depth. These programs pay bonuses based on trading activity and the placement of resting orders on eligible markets. Unlike the one-time welcome bonus, these programs create ongoing earning opportunities for regular traders and can add meaningful value for anyone who trades frequently.
Kalshi offers variable APY on both cash balances and open positions for accounts that meet a minimum balance threshold. This is a significant differentiator from traditional sportsbooks, where your deposited funds sit idle earning nothing while tied up in a bet. On Kalshi, your funds continue working even while they are deployed in open contracts.
Prediction market promo codes work similarly to sportsbook referral codes. During the sign-up process, there is typically a field where you can enter a promo or referral code to unlock a new user bonus. The most important thing to remember is that codes generally cannot be applied retroactively — you must enter the code at the time of registration before making your first deposit. Always verify that a code is current before signing up, as expired codes are common and will not trigger the bonus.
For users in the prediction markets space, it is also worth noting that state restrictions apply. Kalshi’s bonus offer is not available in all jurisdictions due to ongoing regulatory disputes in certain states. Check platform-specific terms before signing up to confirm you are in an eligible location.
Kalshi is our featured prediction market platform, and it offers the most accessible welcome bonus currently available to US traders. New users can claim a sign-up bonus by entering a promo code at registration and completing a qualifying amount of trading activity. The offer is outcome-independent — you receive the bonus after trading the required volume, regardless of whether your positions win or lose, which makes it genuinely low-risk to claim. Visit our dedicated Kalshi promo code page for the current offer details, step-by-step instructions on how to claim it, and information on Kalshi’s referral program and ongoing incentives for existing users.
