Ahead of the World Cup starting in the next few days, there’s an exclusive Polymarket invite code “PREDICTSAIL,” offering new users a $50 trading bonus. This tournament is one of the biggest, so there’s increased interest in prediction markets.
Seeing this, prediction market platforms like Polymarket allow you to forecast events and trade yes/no contracts against other users. And now, in anticipation of the World Cup, more than 100 markets have started trading, including outright winners, player awards, and even specific player appearances. In this article, we’ll explore more about this platform and the ongoing Polymarket welcome promo.
What does the Polymarket bonus entail?
As someone who just wants to sign up on Polymarket, there’s a running promo where the operator gives you $50 in trading bonus. But to unlock this offer, you have to first use the “PREDICTSAIL” invite code. You should also keep in mind that this promo is only available within the June to July window during which the World Cup takes place.
Additionally, being one of the most active platforms for prediction markets out there, this Polymarket offer is open to new US accounts across 42 states. So if you reside in a supported region and want to claim it, below are the steps to follow:
- Visit Polymarket’s official site on your mobile or desktop
- Click the Sign Up button and fill in your correct details
- Enter “PREDICTSAIL” in the space for invite code
- Complete any identity verification required
- Make a minimum first deposit of $20 to instantly activate the $50 bonus credit
Available trades you can use the operator’s bonus on
Polymarket currently lists more than 100 dedicated 2026 World Cup markets. As such, it’s one of the best platforms to place yes/no sports prediction contracts this summer, after claiming the Polymarket signup bonus.
For instance, the World Cup Winner market has crossed $2 billion in lifetime trading volume and carries over $280 million in active liquidity. So it means there’s no shortage of sports prediction markets you can trade on this site.
At the moment, though, these are the top favorites you’ll find here. But keep in mind that the probability values might change depending on several factors:
| Country | Market probability |
| France | 16-17% |
| Spain | 16% |
| England | 11% |
| Portugal | 10% |
| Argentina | 9% |
| Brazil | 8% |
Beyond the outright winning national team, you’ll also find group stage markets running parallel, with Mexico currently priced at 54% to top Group A. Player award markets are also active, showing Harry Kane and Kylian Mbappe as the leading charges of the Golden Boot market. Added to that, there’s a hyper-specific Polymarket Lionel Messi World Cup Appearance Contract that’s currently trading at 98%, which is the probability that the legend will participate in his sixth World Cup tournament.
A more detailed look at Polymarket
If you’re new to how this platform works, we have a dedicated Polymarket review that breaks down all you need to know. But for now, one of the most important features to keep in mind is the core mechanic behind it: Instead of placing wagers, you trade yes/no contracts against other users, with prices shifting based on collective opinion. Essentially, it’s a crowd-sourced model, which means markets tend to react based on breaking team news and injuries faster than traditional outlets.
Furthermore, to make its features more accessible, Polymarket has partnered with Bitget Wallet to bring these dynamic World Cup markets directly to 90 million mobile users. While downloading the wallet and tracking live odds is completely free, you’ll need to fund your account to place actual trades. Fortunately, new users can get a head start by checking for Polymarket promo codes that can trigger active offers. Using a code like PREDICTSAIL can unlock a $50 trading bonus when you make your first $20 deposit.
