Deposit $10, Get $20 in Trade Credits
New users can claim Polymarket’s current welcome bonus — Deposit $10, Get a $50 Trading Bonus — using a promo code during registration. The offer follows a deposit-and-get structure: fund a new account with at least $10, and once that deposit clears, Polymarket automatically credits the $50 trading bonus to the account, for $60 in total trading funds. No trade is required first to unlock it — you don’t have to place a bet or wait for a market to settle before the bonus lands.
The bonus is issued as promotional trading credit rather than cash, so the credit itself can’t be withdrawn directly, but any profits generated while trading with it are fully withdrawable once they settle. The promotional credit does carry an expiration window after it’s issued (30 days), so new users should plan to put it to use relatively soon after claiming it rather than letting it sit idle. The offer is limited to one per account and is available to new users only, and it cannot be applied retroactively to an existing account. For a deeper look at the platform itself beyond the promo, see our full Polymarket review.
The offer applies to new users only, with one welcome offer per account. Applicants must be 18 or older with a valid U.S. residential address in an eligible state. The Polymarket US app is a CFTC-regulated exchange and is not currently available for sports contracts specifically in Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, Nevada, and Ohio — non-sports markets (politics, economics, culture) may still be accessible in some of those states depending on local regulation. Terms and promotional amounts are subject to change without notice, so it’s worth confirming the current offer directly in the app before depositing.
Polymarket does not charge a flat trading commission on most retail order flow; instead, costs show up through the bid-ask spread and, on some order types, a small maker/taker fee schedule that varies by market. Deposits via ACH bank transfer and debit card are typically free and post within a few business days for ACH or instantly for card; crypto deposits (USDC) settle based on network confirmation times. Withdrawals follow the same rails in reverse. Always check the current fee schedule in the app before trading, since fee structures on prediction market exchanges shift more often than traditional sportsbooks.
Beyond the sign-up bonus, Polymarket periodically features promotional pushes tied to major sporting events, election cycles, and other high-volume market periods — think NFL Sundays, March Madness, and Election Night. These rotate throughout the year and aren’t guaranteed to be active at any given time, and the size of the welcome bonus itself has fluctuated in 2026 as Polymarket has tested different offer structures. It’s worth checking the app’s promotions section after registering to see what else is currently available on top of the ROOKIE welcome offer, and worth confirming the current bonus amount before you deposit since offer terms can change with little notice.
Polymarket’s ROOKIE offer is structured as a straight deposit bonus — put in $10, get credited automatically, no trading requirement attached. Kalshi’s welcome offer, by contrast, requires new users to actually place $25 in qualifying trades within 30 days before the bonus is credited. If you want the simplest path to bonus funds with the least friction, Polymarket’s deposit-only structure is the more straightforward of the two. If you’re comfortable trading right away and want a shot at a larger bonus amount tied to volume, Kalshi’s model rewards early activity. See our Kalshi promo code page for the full breakdown of that offer.

Polymarket US is not currently available for sports contracts in Arizona, Illinois, Massachusetts, Maryland, Michigan, Montana, Nevada, and Ohio. Non-sports markets may still be accessible in some of those states, so check the app directly for your specific location.
The welcome offer is limited to one per new account. Existing users cannot retroactively apply the code.
The promotional trading credit expires 30 days after it’s issued, so it’s best to put it to use relatively soon after your deposit clears rather than letting it sit unused.
Yes. Polymarket US operates through a CFTC-regulated exchange structure, which is why identity verification is required before you can deposit or trade — it’s the same regulatory framework that governs Kalshi and other U.S. prediction market platforms.
Bonus funds can be used across any open market on the platform — sports outcomes, political and election markets, economic data releases, and pop-culture events — not just sports contracts.
