Polymarket Invite Code Delivers $20 Bonus for Friday's Sports Action

The Polymarket promo code COVERS unlocks a straightforward deposit match offer for new users. After registering and entering the code during sign-up, you must deposit $20 to receive an additional $20 in trading bonus funds. This bonus applies to all available markets, including Friday's compelling sports slate featuring playoff-contending teams across multiple leagues.

The welcome offer operates on a 1x wagering requirement, meaning you must trade the full $20 bonus amount once before withdrawing any associated winnings. For example, if you trade on the Timberwolves vs. 76ers game and your position increases in value, you can cash out after meeting the playthrough requirement. Conversely, if your trade loses value, the bonus funds help cushion potential losses while you learn the platform.

Key terms include a 30-day expiration period for bonus funds and eligibility restrictions for users in authorized jurisdictions. The offer applies to all available markets, from NBA playoff races to MLB early-season storylines like Giancarlo Stanton facing his former Marlins team.

Compare this offer with other best prediction market promos to maximize your trading potential.
