Active sub-markets

Market context

The Las Vegas Aces face the Golden State Valkyries on 31 May at 3:30PM ET in a regular-season WNBA matchup. The market currently reflects 100% implied probability for resolution, suggesting traders expect the game to proceed as scheduled without cancellation or indefinite postponement. Settlement closes at 7:30PM ET the same day, allowing roughly four hours post-game for official confirmation.

The Aces have established themselves as a championship-calibre franchise with multiple Finals appearances since 2022, whilst the Valkyries represent Golden State's inaugural WNBA entry in 2024. Historical precedent shows WNBA regular-season games rarely face cancellation; postponements typically occur only for severe weather or facility emergencies, and even then games are rescheduled rather than abandoned. The 100% probability reflects this baseline reliability rather than certainty about either team's performance.

Traders should monitor injury reports through 31 May morning, particularly any late-breaking roster changes that could affect game status. Venue conditions at the scheduled arena merit attention, though May weather in Las Vegas presents minimal disruption risk. The settlement window's four-hour buffer post-game provides adequate time for official scorekeeping and confirmation, reducing the likelihood of technical delays. No recent announcements suggest scheduling complications for this fixture.

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Today, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does it cost to trade on Prediction Today?

Zero. Prediction Today routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
