The Polymarket invite code COVERS offers new users a $20 bonus for Wednesday's Celtics vs. Heat matchup. Jaylen Brown seeks redemption after his self-described "worst game of the season" in Boston's loss to Atlanta, making this Eastern Conference clash an intriguing prediction market opportunity.

The April 1 welcome offer requires depositing $20 to unlock the reward on one of the best prediction market apps available.

Polymarket Invite Code Details for Celtics vs. Heat

The Polymarket promo code COVERS provides a straightforward "Deposit $20, Get $20 Trading Bonus" structure for new mobile users. Unlike traditional sportsbook promotions, this prediction market offer requires an initial $20 deposit to activate the matching bonus funds. The terms typically include eligibility restrictions for new users meeting legal age requirements in authorized jurisdictions, with bonus funds subject to standard playthrough requirements before withdrawal.

For the Celtics-Heat game, traders can explore various prediction markets including game winner, player performance props, and team totals. If you predict Boston bounces back behind a healthy Jayson Tatum and win your $10 trade, you'd receive your stake plus winnings. Should Miami's defensive struggles continue and your Heat prediction loses, you'd forfeit the traded amount but retain unused bonus funds for future markets.

Key terms include minimum deposit requirements, qualifying trade stipulations, wagering requirements typically ranging from 1x to 3x the bonus amount, and expiration dates usually within 7-30 days of account creation. Market restrictions may apply to specific events or outcomes, making it essential to review complete terms before trading. Compare this offer with other best prediction market promos to maximize your trading potential.
