Use the Polymarket promo code SIBONUS to deposit $10 and get a $25 trading bonus on NBA, NHL and NFL Week 10 markets. | Sports Illustrated

Deposit $10, get a $25 trading bonus with the Polymarket promo code SIBONUS. A code is required, and the offer is live as of Wednesday, November 11. New users can use it on NBA, NHL and NFL Week 10 markets, and you can browse more prediction market promos too.

18+ Only. Restrictions and eligibility requirements apply. Not available in all jurisdictions. Trading is risky. 100% loss can occur. See http://polymarket.com/tos  for more information. The Polymarket US App serves as an independent software provider and affiliate of Polymarket US and Polymarket Clearing, the CFTC-regulated exchange and clearing organization.

How the Polymarket Promo Code Works for NBA, NHL and NFL Week 10 Trading

The Polymarket promo code is SIBONUS, and a code is required to unlock the welcome offer. You must enter it during registration, because you generally cannot apply a promo code after your account is created. The offer is a $25 trading bonus after a $10 deposit.

The offer is not tied to one outcome. For this promotion, I treat Wednesday's NBA doubleheader as trade 1, with Cleveland at New York at 7 PM ET and Golden State at Houston at 9:30 PM ET. From there, you can move to NHL games such as Tampa Bay at Buffalo at 7 PM ET, then to NFL Week 10, which opens Thursday with Washington at New York at 8:15 PM ET.

Here are the key terms and conditions for the welcome offer:

• The code SIBONUS is required at registration.
• The offer is available in all states except Nevada.
• You must be physically located in an eligible location.
• You must provide proof of ID, which includes a photo of a driver's license or passport and a selfie holding that ID.
• You must make an initial deposit of $10.
• You must complete a real-money trade on any eligible market to claim the bonus.
• The bonus carries a 1x playthrough requirement. Once you meet it, any profit from your trades is yours and can be withdrawn as cash.
• The same promotion is available to eligible iOS and Android users who register through a qualifying promotional campaign and meet the offer's terms.

Polymarket no longer requires an invitation to create an account, and the previous U.S. waitlist has been removed for eligible users. The promo code is also different from a referral link. SIBONUS unlocks the new-user welcome offer, while referral links belong to the separate refer-a-friend program.

Here is a simple example of how the offer can work. Say you deposit $10 and place your first trade on a market tied to a featured game. Your $25 trading bonus is credited once you meet the requirements, and you can use it on your next trades. If a trade resolves in your favor, you keep the profit once the 1x playthrough is met. If a trade resolves against you, the amount you traded is not returned, but the rest of your balance stays available for other markets.
