On mobile, download the Polymarket app, sign up with an email or Google account and enter Polymarket invite code SBWIRE when prompted during registration. On desktop, scan the in-app QR code to pull up the mobile download, then register the same way. From there, verify identity with a government ID and load at least $20 into the account. The $50 credit posts right away, with no rollover attached.
One thing worth flagging: The code only works if it’s entered at sign-up. There is no way to add it retroactively, so double-check it’s typed in before finishing registration.
What Trading on Polymarket Actually Looks Like
Polymarket isn’t a sportsbook in the traditional sense. Instead of betting against a house, traders buy and sell contracts tied to how real events will turn out, from elections to economic reports to sports outcomes.
Each market is framed as a yes or no question, and share prices track the crowd’s implied odds. A $0.35 share on a “yes” outcome suggests the market sees roughly a 35 percent chance it happens. Correct calls pay a dollar per share, wrong ones pay nothing, and positions can be closed early if sentiment shifts before a market resolves.
Availability of the New Polymarket Invite Code SBWIRE
Polymarket runs its U.S. operations through QCEX, a CFTC-registered exchange, giving it firmer legal footing than in its earlier years. Trades settle on the Polygon blockchain in USDC, keeping activity traceable on-chain.
Coverage extends to 48 states and Washington, D.C., with Nevada and Minnesota still excluded. Prediction markets remain a developing regulatory category, so terms can shift. Traders should check current platform rules before funding an account and must be 18 or older with verified identity to trade.
Polymarket Referral Program
Beyond the new-user code, Polymarket offers a separate referral system for existing traders. Accounts need $10,000 in lifetime volume to unlock a referral link. Once active, referrers earn an uncapped share of trading fees generated by anyone who signs up through that link.
A current promotional window pays 30 percent of fees from direct referrals and 10 percent from second-degree referrals for 180 days, though Polymarket can adjust that structure at any time. Trading fees themselves run as high as 1.8 percent on crypto markets and as low as 0.75 percent on sports.
Deposit and Withdrawal Options
Funding works differently than a typical betting account, built primarily around USDC on Polygon. Supported methods include:
