Polymarket continues to rise as one of the best prediction market apps in the U.S., and now is the perfect time to join. With the Polymarket promo code LABS, you can deposit $20 and get a $20 bonus while bypassing the 1 million+ people on the waitlist. This early access gives you a head start on trading sports markets directly from your mobile device.


Get Early Access with Polymarket Invite Code LABS
Polymarket remains in a limited U.S. beta, and it requires an invite code to create an account. By using a Polymarket invite code LABS, you unlock the app instantly, skip the line, and claim your welcome bonus. Account creation is simple: download the mobile app and register using your Apple or Google account. Keep in mind, desktop browsing allows you to view markets, but trading and deposits only work on the app, so make sure you’re ready to trade from your phone.


Trade Today on Sports Markets
Polymarket focuses on sports markets for now, giving fans a chance to predict game outcomes and win rewards. Polymarket has also partnered with MLB, adding credibility and excitement for baseball fans.
While MLB action continues, the spotlight today (Monday, March 30) is on the March Madness Final Four, with the following games on Saturday, April 4.
- Illinois vs. UConn at 6:09 p.m. ET on TBS
- Michigan vs. Arizona at 8:49 p.m. ET on TBS
These high-stakes matchups create ideal opportunities to trade and capitalize on market movement in real time.
Use the Polymarket promo code LABS to start trading these games instantly and take advantage of the $20 bonus when you deposit $20.

- Deposit $20, get $20 bonus to kickstart your trades
