If you're searching for a Polymarket promo code or sign-up offer, then you'll be pleased to know that eligible US users can enter the code DIMERS when creating an account and deposit at least $10 to receive a $50 trading credit.
The credit isn’t cash you can withdraw immediately, as it must first be used for trading. However, it's still a great way to claim extra credits and explore more markets on the platform. Below, we break down the mechanics of the current welcome offer, why the platform prioritizes liquidity-based rewards for its user base, and more.

Polymarket rewards features

Does Polymarket Offer Rewards to Existing Users?
While the Polymarket welcome bonus is designed to get you started, the platform has also shifted its focus toward long-term sustainability for existing traders.
Rather than offering traditional, one-off bonuses, Polymarket prioritizes market health and participant engagement through performance-based incentives, a priority reinforced in March 2026 when the platform rolled out enhanced Market Integrity Rules to keep trading fair across the board. These programs are designed to reward consistent activity, liquidity provision, and community growth.
Liquidity Rewards
As we noted in our
Polymarket review, Polymarket also offers Liquidity Rewards, which encourage users to place orders in specific markets to help maintain balanced pricing.
For markets trading near the extremes (below 10¢ or above 90¢), you'll need orders on both sides of the book to qualify; closer to the middle, single-sided liquidity still earns a reduced reward, and payouts require at least $1 earned in a day. It's worth keeping this separate from Polymarket's Maker Rebates program, which only pays out when a resting order actually fills.
Eligible markets are listed on Polymarket's Rewards page, where you can check daily earnings, see which markets currently have rewards active, and view the total reward amount available for a given market directly in its order book.
Referral Program
The
Polymarket referral program
lets you invite someone who doesn’t already have a Polymarket US account by sharing your username as a referral code.
If that person uses your code to register and deposits at least $10, you’ll both receive a $50 trading credit. Each user can earn credits from up to 14 qualifying friend referrals, and keep in mind that the credits must be used for trading before any funds can be released.
Maker Rebates
Separate from Liquidity Rewards, Polymarket's Maker Rebates program only pays out once a resting order you've placed actually gets filled by another trader, rather than simply for sitting on the book. A portion of the taker fees collected in eligible categories flows back to the makers whose liquidity absorbed that volume.
The share ranges from 15% in Sports markets up to 25% across most others, including Politics, Finance, and Culture, while Crypto sits at 20% and Geopolitics stays fee-free entirely. Rebates are calculated separately within each market, so you're only competing against other liquidity providers quoting that same book, and payouts land daily in pUSD once your accrued total clears the platform-wide $1 minimum.
Taker Rebate Program
Rounding out the rewards on offer is the Taker Rebate Program, which went live in late May 2026 and flips the incentive around: instead of rewarding you for adding liquidity, it rewards you for taking it. Every taker trade contributes to a rolling 30-day "Weighted Volume" score, shaped by trade size, how far your entry price sits from the middle of the range, and a category multiplier that weighs Crypto trades more heavily than lower-volatility categories like Sports.
That score places you into one of seven tiers, from Bronze at $2,000 up to Obsidian at $10 million and beyond, with rebates scaling from 3% up to 50% of your taker fees plus a one-time bonus, worth as much as $25,000 at the top tier, the first time you reach it. Like the other programs, payouts are daily in pUSD once you clear $1 in accrued rebates, though your improved rate only applies to trades going forward.
