Resolution criteria on PolyGram: This market will resolve according to the date on which the WNBA and WNBA players association sign a new collective bargaining agreement (CBA). The listed market will resolve to "Yes" if the date of signing is between market creation and the listed date 11:59 PM ET. Otherwise, the listed market will resolve to "No." For purposes of this market, a CBA is considered ‘executed’ only when the final written agreement has been formally signed by authorized representatives of both the WNBA and the WNBA Players Association. Tentative agreements, ratifications, or agreements pending signature do not qualify. The resolution source will be a consensus of credible reporting.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| January 31 | 0% YES | 100% NO |
| March 31 | 0% YES | 100% NO |
| June 30 | 97% YES | 3% NO |
The WNBA and its players association must negotiate and execute a new collective bargaining agreement by 30 June 2026 for this market to resolve affirmatively. The current 0% implied probability on Polymarket's order book reflects the substantial time remaining and the absence of any signed agreement to date. This probability is formed by the spread between bids and asks among traders, with no current market depth supporting a YES position at meaningful odds.
The WNBA's most recent CBA was ratified in 2020 and runs through the 2024 season, establishing a historical precedent for multi-year labour agreements in the league. Previous negotiations have typically commenced 12–18 months before expiration, with formal discussions beginning in earnest once the existing deal enters its final year. The 2020 agreement took approximately four months of active negotiation following the union's initial proposal, though the timeline varied considerably from earlier cycles. Given the 2024 expiration, formal talks would ordinarily commence in late 2023 or early 2024.
Traders should monitor announcements from WNBA commissioner's office and WNBA Players Association leadership regarding negotiation commencement, which typically signal movement toward a settlement window. Recent reporting on player compensation demands—particularly regarding salary floors, revenue sharing, and marketing rights—will shape negotiation complexity. The settlement window extends to mid-2026, providing approximately 18 months from typical negotiation start dates, though the 0% probability suggests the market currently discounts near-term agreement likelihood or reflects minimal trading activity in this contract.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
The mechanics for trading "New WNBA CBA agreement by...?" are the same as any other PolyGram sporting event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$18K in lifetime turnover and $286 of resting liquidity puts this market in the below the median by volume for sports contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for 4 months — the price has had time to stabilise as new information arrived.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a 2-hour dispute window opens, and if uncontested the payout is final. Contested outcomes escalate to UMA token holders.
This prediction market is scheduled to close on 30 June 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.

Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
