How the Polymarket Referral Code Offer Works

New users can claim the Polymarket promo code COVERS to receive a $25 trading bonus after signing up and making a qualifying $10 deposit. The code must be entered during registration and cannot be applied once an account already exists. Eligible users in most states, excluding Nevada, can use the offer to trade on markets surrounding Tuesday's Celtics vs. Pistons opener.

  • Deposit at least $10 using a debit card, bank transfer, Apple Pay or crypto.
  • Enter the code during sign-up to activate the bonus.
  • Complete a 1x playthrough requirement before withdrawing profits.
  • Provide valid ID verification, including a photo ID and a selfie.

For example, a trader who places a $10 position on a market tied to the Pistons winning Tuesday's opener and sees that outcome occur could collect returns on the trade in addition to the bonus funds once the playthrough requirement is met. If the Celtics win instead, that initial $10 stake would be lost, but the $25 bonus remains available for future trades once terms are satisfied. These scenarios show how the bonus can support a trader's bankroll regardless of how the opener plays out.

Traders looking to earn more value should also explore the Polymarket referral code program, which rewards members for inviting others to the platform. For a complete breakdown of similar sign-up offers, check out the best prediction market promos comparison page.

Polymarket traders can find value in the Celtics-Pistons Opening Night matchup, with Boston vs. Detroit picks drawing attention from multiple experts.

  • Tom Oldfield predicts Boston to win, noting the Celtics were 28-16 straight up on the road last season and that Detroit's over-reliance on Cade Cunningham and uncertainty surrounding Jalen Duren give the new-look Celtics a clear edge.
  • Jon Metler backs Boston to cover the spread at +2.0, arguing that Paul George's versatility as a perimeter defender who can switch onto Cunningham adds a valuable dimension, while George's three-point-heavy shot diet and quick decision-making fit the Celtics' offense, with Jalen Duren's roster status adding further uncertainty for Detroit.
