Polymarket Promo Code: How to Earn Money, Referral Codes and the “Free 25” Bonus

I’ve always been a sports bettor, and Oddspedia is all about betting. But you can’t avoid prediction markets right now, especially when huge marketing budgets mean big bonuses for customers. I’ve taken a quick look at Polymarket, one of the biggest prediction markets around, to see how much money you can earn as a customer.

If you are still deciding where to trade, our guide to prediction market platforms compares Polymarket with four alternatives. You can also check the latest Kalshi promo code when comparing the welcome offers available from the two platforms.

No trading strategies, just bonuses

The first thing to clear up is that I’m not here to give you an edge over the market. I have a few observations to share, but there are no complex strategies here. This is simply a rundown of the extra funds Polymarket offers customers through the Polymarket promo code COVERS, its refer-a-friend scheme and the Free 25 bonus.

Prediction markets are presented in many ways, but the honest framing is the simplest one: Polymarket is a trading venue, not a lottery ticket. Some traders do make consistent money on it. Most don’t.

The difference usually comes down to having an actual edge, not luck. Knowing how to stack the free money on the table through a promo code, a referral code and the sign-up bonus is the easiest place to start.

Step one: Claim the Free $25 with code COVERS

Before you think about strategy, there is a straightforward $25 sitting on the table for new users. Enter the Polymarket promo code COVERS when you sign up, deposit at least $10 and you’ll receive a $25 trading bonus, a 250% match on that initial deposit.

A few things are worth knowing before you fund the account:

• The bonus is not cash you can withdraw directly. It lands as trading collateral and only becomes withdrawable once it is “released” through position settlement or liquidation, meaning you have to trade with it first.
• You need to complete identity verification. Skipping or failing KYC can forfeit the bonus entirely, so finish that step before you count on the funds.
• You have to use the Polymarket promo code COVERS when you sign up. Others are available, but I use Covers daily, so I used the one published on its site.
• Eligibility is broad but not universal. Polymarket US currently excludes Nevada, and a handful of other states have disputed the federal classification of certain contract types. It is worth taking 10 seconds to check your eligibility in the app before you deposit.

The practical upshot is to treat that $25 as free trading capital for building your first positions, not as money you can withdraw immediately.

Step two: Stack the referral code for up to $1250 more

The Polymarket code COVERS does double duty as Polymarket’s referral offer, and it is worth using even if you are trading solo because, unlike the promo code, it is not a one-time offer.

Here is how it works: when a new user signs up using a referral code or invite link, completes verification and deposits at least $10, both the referrer and the new user receive $25 in trading credits. You can do this up to 50 times, which caps the reward at $1250 in total. That is a meaningfully larger amount than the initial $25 if you know a few people who would also like to try Polymarket.

Two mechanical details matter here:

1. The Polymarket referral code COVERS has to be entered during sign-up, just like the promo code. It generally cannot be added afterwards.
2. Only one bonus is paid per verified identity. Polymarket explicitly prohibits self-referrals, referring accounts you control or creating multiple accounts to claim the reward. Attempts to game the offer can result in bonuses being clawed back or accounts being suspended.

Between the $25 sign-up bonus available with the Polymarket promo code COVERS and a handful of referrals, it is realistic to start with several hundred dollars in trading credits without contributing anything beyond the minimum deposit. Maximise the offer, and you will have $1275 in added funds, comprising $25 from your welcome bonus and $1250 from referrals.

Can you actually make money trading your bonus funds?

This is where most “promo code” articles stop and most people’s actual results start going sideways. Free credits help you get started, but they do not create an edge. On Polymarket, that edge is what separates traders who come out ahead from those who do not.

As I said earlier in this article, this is by no means expert trading advice. However, here is a summary of a few approaches that consistently appear among traders who take it seriously:

• • Trade what you actually know. Nobody has an edge in every category. Traders who do well tend to specialise in one sport, one political cycle or one industry, rather than spreading themselves thinly across every market on the board. If you follow college football closely, that knowledge is worth more than a surface-level read of 12 different markets.
  • Use limit orders instead of market orders. This is the simplest, least skill-dependent way to keep more of what you make. A market order takes whatever price is available at that moment, while a limit order lets you set the price at which you are willing to trade and wait for it. The difference adds up over dozens of trades and represents a meaningful portion of the spread you would otherwise give away.
  • Watch what experienced traders are doing carefully. Polymarket’s on-chain nature means wallet activity and trading history are publicly visible, and some traders build a track record you can study. Copying a position after the event means paying a worse price than they did, so this works better as research than as a mechanical copy-trading strategy.
  • Move quickly on breaking news if you are set up to do so. There is typically a window of anywhere from 30 seconds to a few minutes between real-world news breaking and a market’s price fully catching up. Traders who can react quickly and interpret the news accurately can capture that gap. This is a genuinely competitive space, though, and one increasingly contested by automated trading.
  • Consider high-probability contracts at a discount. Buying a contract priced at 92 to 96 cents on an outcome you are confident is close to a lock will not make you rich on any single trade, but it can be a steady, lower-variance way to compound smaller gains, provided you are honest with yourself about how “locked in” the outcome really is.
  • Understand that arbitrage betting exists, but do not expect easy money. Price discrepancies between correlated markets do appear and, in theory, allow you to lock in a small risk-free profit. In practice, automated trading bots typically close these gaps within seconds. It is a real strategy, but not usually an accessible one for a manual retail trader.

The part most bonus articles skip: Risk management

The uncomfortable number worth knowing before you begin is that a large share of Polymarket traders, commonly cited at around 80%, lose money over time. That is not a reason to avoid the platform, but it is a reason to treat it like trading rather than entertainment:

• Size positions deliberately. Do not put a large share of your balance into a single contract, no matter how confident you feel.
• Diversify across uncorrelated events. This means one bad outcome does not wipe out a string of good decisions elsewhere.
• Read the resolution criteria before you trade, not afterwards. Markets settle according to specific, sometimes narrow definitions. What you assumed the contract meant is not always what it actually pays out on.
• Do not chase losses. Increasing your position size to “win back” a bad trade is one of the most consistent ways to turn a manageable loss into a large one.

Putting it together

The realistic version of “how to earn money on Polymarket” looks like this: claim the $25 welcome bonus with the Polymarket promo code COVERS, stack a few referrals for up to $1250 more if you know other people who would like to join, and use that cushion of free trading capital to build positions in a category you understand. Use limit orders, size your positions sensibly and learn how the market behaves. The bonuses lower your cost of entry, but they do not replace having an actual edge, and nothing here guarantees a profit.

Polymarket promo code FAQs

Is the $25 Polymarket bonus real cash?

It lands as trading collateral, not as a direct cash balance. You need to use the Polymarket promo code COVERS, trade with your bonus and have your positions settle before any resulting funds become withdrawable.

Can I use the promo code and referral code together?

Yes. They are separate mechanics: the Polymarket promo code COVERS gives you the $25 welcome bonus as a new user, while the same COVERS code works as a Polymarket referral offer that pays $25 to both you and anyone you refer, up to 50 times.

Do I need to be an expert trader to make money on Polymarket?

No, but traders who perform consistently well tend to specialise in categories they already understand, rather than trading broadly across everything on the platform.

Is it possible to lose money on Polymarket?

Yes. This is real trading with real risk, not a guaranteed-return product. A majority of traders are commonly reported to lose money over time, which is why position sizing and diversification matter as much as selecting good trades.

Is Polymarket legal where I live?

Polymarket US is available in the large majority of states. Nevada is currently excluded, while a small number of other states have disputed the status of certain contract types. Confirm your eligibility in the app before depositing.

Bonus terms, referral caps and state eligibility are subject to change. This article is for informational purposes and is not financial advice. Trading on Polymarket carries a real risk of loss. Always confirm the current terms directly with Polymarket before signing up.
