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 $25 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.
Yes, at the time of writing, this top prediction market site offers eligible users a $25 trading credit when they register with the Polymarket promo code DIMERS and deposit at least $10. Once that's done, Polymarket will add the credit after confirming the deposit qualifies.
18+ Only. Restrictions and eligibility requirements apply. Not available in all jurisdictions. Trading involves high risk and may result in loss of your entire investment. See polymarket.us/tos for more information. The Polymarket US App serves as an independent software provider and affiliate of Polymarket US and Polymarket Clearing, the CFTC-regulated derivatives exchange and clearing organization.
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.
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.
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 $25 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.
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.
| Market Category | Maker Fee Rebate Share |
|---|---|
| Politics, Finance, Culture | 25% |
| Crypto | 20% |
| Sports | 15% |
| Geopolitics | Fee-Free (0% Taker / Exempt) |
Rebates are calculated independently per market and distributed daily in pUSD once your accrued balance reaches the $1.00 minimum threshold.
Launched in May 2026, the Taker Rebate Program rewards traders taking liquidity from the book based on a 30-day rolling Weighted Volume score (factoring in trade size, distance from midpoint, and market category multipliers). Higher monthly volume unlocks higher tier rates applied to all future trades:
| Tier | 30-Day Volume Threshold | Taker Fee Rebate | Level-Up Bonus |
|---|---|---|---|
| Bronze | $2,000 | 3% | N/A |
| Silver–Diamond | $10,000 – $2,500,000 | 5% – 35% | Silver Scaled Bonus |
| Obsidian | $10,000,000+ | 50% | Up to $25,000 (One-time) |
Like Maker Rebates, Taker payouts land daily in pUSD once you clear the platform-wide $1 minimum.
