Polymarket prepared a fresh $20 referral code, CUSE, for the Chicago Sky and New York Liberty WNBA matchup on Wednesday, July 22nd, 2026. For readers tracking the Sky vs. Liberty market, the timing matters because the code was tied directly to the game and the event market around it.
Eligible first-time users who used CUSE and made a qualifying $10 deposit received $30 in total starting purchasing power ahead of tonight's Sky-Liberty game. In other words, the promotion was built to give new users an easier entry point into the market before tipoff.
What the market was showing
Polymarket prices can shift throughout the day before tipoff as money enters or exits the market, so the listed numbers were a snapshot rather than a final read on the game. The market had the Sky at 73¢ and the Liberty at 28¢, with the total set at 179.5 points.
The source also listed Dimers projections in the background, including a 52¢ view on one side of the market, 67.3%, 14.4%, -112, 8.5, 54.0%, 2.8%, -105, $10, $30, 49¢, 7.5 and 52¢. Those figures were presented as market opinions rather than a separate event.
Why it matters
For a matchup like Sky vs. Liberty, the key takeaway is simple: Polymarket tied a new-user promotion to a specific WNBA game and gave eligible users a clear bonus structure. That makes the game relevant not just as a basketball event, but also as a live prediction-markets opportunity for anyone following the numbers ahead of Wednesday's tipoff.
