Polymarket Invite Code Details for Michigan vs. Arizona

The Polymarket promo code COVERS provides new users with a $20 trading bonus after depositing $20 into their account. This welcome offer differs from traditional sportsbook promotions as it focuses on prediction market trading rather than standard sports betting. Users can trade on various outcomes related to the Michigan-Arizona game, including final scores, player performances, and game totals.

The bonus comes with standard terms and conditions typical of prediction market platforms. New users must be of legal age and reside in eligible jurisdictions where Polymarket operates. The $20 deposit requirement activates the bonus, which typically carries a 1x wagering requirement before withdrawal. For example, if you trade the full $20 bonus on Michigan covering the spread and win, you could withdraw your winnings after meeting the playthrough requirement. Conversely, unsuccessful trades would result in losing the bonus amount, similar to any prediction market outcome.

Bonus funds generally expire within 30 days if unused, and certain market restrictions may apply. The offer specifically targets mobile app users, with desktop visitors directed to a waitlist for future access.
