Polymarket $20 Bonus

Currently, eligible new Polymarket users have the opportunity to take advantage of a welcome promo by registering on the site. Traders who open an account with a minimum deposit of $10 may qualify for a $20 trading bonus by using a promo code at sign-up.

With this promo, new users can use extra money for trading in order to discover all the features of Polymarket’s prediction markets, including those that deal with politics, cryptocurrency, sports, and many more.

Please note that the promotions offered in the sphere of prediction trading can be very fast-changing, and it’s worth finding out more about them beforehand.

The good news is that getting started with Polymarket is relatively simple. Once your account is created and funded, you can immediately begin trading on live event contracts and market outcomes.

What is Polymarket?

If you’re unfamiliar with Polymarket or prediction market trading in general, it’s still a good idea to learn how the platform works before risking funds. Understanding concepts like market pricing, probability percentages, and settlement rules can make a big difference when placing your first trades.

I recently put out an in-depth Polymarket review which covers everything you need to know in that regard.

But the basics are as follows.

Polymarket Is a Prediction Market Platform

Here, you can buy “yes” and “no” event contracts tied to potential sports, politics, culture, crypto and pop culture predictions.

For example, trending topics at the time of writing include “Will Viktor Orban be re-elected as President of Hungary?” and “Will the US confirm aliens exist before 2027?”.

Each contract comes with a percentage probability set by supply and demand in the market – for example, Polymarket users currently reckon there’s a 19% chance that the “aliens are among us” announcement will come soon, meaning a “yes” contract trades at $0.19.

Although naturally, probabilities and prices fluctuate in real time.

If an outcome occurs, any contracts you hold will settle at $1 (or at $0 if it doesn’t).

How to Claim Polymarket $20 Promo Code Offers

When and where available, I’ve found that welcome bonuses at Polymarket are generally easy to claim on the site.

This is how to use codes on Polymarket:

  1. Click any of my direct links here to reach Polymarket’s official site

  2. Tap the blue “Sign Up” icon or scan the QR code on your phone

  3. Enter your email address, or click to register via Google, MetaMask, CoinBase or Phantom if preferred

  4. Link your email address or crypto wallet to Polymarket using the registration code they’ll have sent to your email/account

  5. Fill out Polymarket’s sign up form. This is where you enter the promo code PREDICTSAIL at the bottom of the page.

  6. Read and accept the site’s T&Cs and Privacy Policy – noting that Polymarket is only available in selected US states

  7. Make a deposit to fund your account and start buying/trading event contracts

  8. Depending on the bonus in question, you might sometimes be restricted to specific markets – for example, a politics-themed promotion offering a trading credit on presidential elections won’t be usable on Polymarket’s sports markets, and vice-versa.

  9. Meanwhile, regional T&Cs might also apply depending on which eligible US state you’re signing up from – so be sure to give these a thorough read, too.

Other Rewards Available with Polymarket Bonus Code

Polymarket also offers a handful of rewards programs targeted at existing – rather than new – users. These include:

Liquidity Rewards Scheme

The Polymarket Liquidity Rewards program effectively rewards traders for making “helpful” trades. Simply put, if you buy or sell event contracts and other traders buy or sell at your prices, rewards will hit your account. Although the formula used for calculating said rewards isn’t exactly what you’d call clearly defined.

Holding Rewards Program

Meanwhile, the site’s Holding Rewards scheme dishes out small daily rewards to traders who hold eligible event contracts in qualifying markets, such as Polymarket’s election markets, for example, over time. Qualifying contracts are listed – and regularly rotated – via the site’s “Rewards” tab.

Refer a Friend Commissions

Last but not least, I found that when you refer other users to the platform, you can potentially collect a percentage of the Polymarket fees they pay while trading. Referral commissions are currently uncapped, and boosted rates can sometimes be locked in during special promotional periods.
