Polymarket Promo Code: Offer Details (June 8)

Use the Polymarket promo code ACTION during sign-up and make a $20+ first deposit to get a $50 trading bonus. Since the $50 bonus hits immediately, you start with at least $70 ($20 + $50) in trading bankroll to use on NBA Finals predictions on June 8 or any market you prefer.

Spurs vs. Knicks is the kind of one-night window where a trading bonus can meaningfully expand your options. On Polymarket, you’re trading outcome contracts, which lets you take a position into pre-tip price swings without committing a large amount of cash. The offer adds $50 in promo credits after a $20 deposit, giving you room to scale in, hedge, or close early if the market moves in your favor.

This fits readers who prefer prediction market apps over fixed payouts and want to manage a position as prices update in real time. For timing, the clean move is to fund before the 8:30 p.m. ET tip on ABC so you’re not chasing liquidity after the market reacts.

How to Use the Polymarket Offer on Spurs vs. Knicks Game 3

I like using this offer for flexibility, not one all-in take. Let's say I want to trade on the NBA Finals Game 3 on Monday, June 8. If I open a $50 position on a Spurs vs. Knicks market at $0.40, I start by signing up and entering Polymarket promo code ACTION, then I make the required $20 deposit to unlock the $50 trading bonus. At $0.40 per contract, that $50 position buys about 125 contracts (50 / 0.40). If my position settles Yes at $1.00 after entering at $0.40, profit is $0.60 per contract, so that’s about $75 profit (125 x $0.60). If it settles the other way, I can lose the position amount.

Now I’ll split exposure instead of forcing one view. After that $20 deposit, I can use the $50 promo credits on a separate eligible market, then keep my cash smaller on Spurs vs. Knicks. Example: I open a $10 Yes position at $0.50, which buys about 20 contracts; if it settles at $1.00, the payout is about $20 and the profit is roughly $10, and if it settles the other way I lose $10, but I still keep the $50 in promo credits from the offer. Quick checks before tip:

  • Make sure the Spurs vs. Knicks market is actually open in your location.
  • Confirm the current contract price and the buy/sell spread before you trade.
  • Check time remaining before the 8:30 p.m. ET start, since liquidity can change fast near tip.
