Polymarket Launches $20 Bonus for New Users with Invite Code SBWIRE
Polymarket, a cryptocurrency‑based prediction‑market platform, has announced a new promotional offer that rewards new users with a $20 credit when they sign up using the invite code SBWIRE and deposit at least $10. The promotion is available to residents of 48 U.S. states and Washington, D.C., excluding Nevada and Minnesota.
The offer is designed to give new traders a head start on the platform’s wide range of markets, which include sports events such as NFL preseason games, college football, PGA, MLB, and WNBA, as well as political, economic, and crypto‑related outcomes. According to the platform’s own description, the $20 bonus is credited immediately after the initial deposit and does not require any rollover or additional wagering.
Polymarket operates through QCEX, a Commodity Futures Trading Commission (CFTC)‑registered exchange. Trades are settled on the Polygon blockchain in USDC, providing on‑chain traceability. The platform’s legal structure and regulatory compliance allow it to offer prediction markets in most U.S. jurisdictions, but it remains subject to state‑level gambling restrictions. Users must be 18 or older, verify their identity with a government ID, and meet the platform’s minimum deposit requirement.
Unlike traditional sportsbooks, Polymarket does not take bets against a house. Instead, traders buy and sell shares that represent the likelihood of a specific outcome. A share priced at $0.35 on a “yes” outcome implies a 35% probability according to market sentiment. Correct predictions pay $1 per share; incorrect ones pay nothing. Positions can be closed early if sentiment shifts before a market resolves.
The platform’s fee structure varies by market type. Sports markets carry a fee of 0.75%, while crypto markets can reach up to 1.8%. Existing traders who have generated $10,000 in lifetime volume can unlock a referral link that earns them a share of the trading fees generated by new users who sign up through that link. During the current promotional window, the referral program offers 30% of direct referral fees and 10% of second‑degree referral fees for 180 days, though the terms may change at any time.
Funding methods are diverse. Users can add USDC via a crypto wallet, a card or fiat transfer, a cross‑chain bridge, an exchange transfer, PayPal, Apple Pay, or Apple Cash. The platform’s mobile app allows users to register with an email or Google account, enter the invite code during sign‑up, and complete identity verification. On desktop, users can scan a QR code to download the mobile app and follow the same process.
Polymarket’s markets cover a broad spectrum of real‑world events. In addition to sports, users can trade on political outcomes, economic reports, and even military actions. The platform’s structure encourages real‑time sentiment analysis, but it also requires users to be mindful of regulatory changes, as prediction markets are still a developing category.
The $20 bonus promotion is part of Polymarket’s effort to attract new traders ahead of the NFL preseason, which begins on August 6. The platform already hosts a variety of NFL markets, including a contract on the Super Bowl winner. By offering a funded head start, Polymarket aims to increase participation in its sports markets.
In summary, new users in eligible U.S. states can receive a $20 credit by signing up with the invite code SBWIRE and depositing $10 or more. The credit is immediate, has no rollover, and is available on a platform that operates under CFTC oversight and settles on the Polygon blockchain. Existing users can also benefit from a referral program that rewards trading volume. The promotion is active as of July 29, 2026, and is subject to the platform’s terms and state‑level gambling regulations.
