Las Vegas Aces vs. New York Liberty

Platform comparison

Market context

The Las Vegas Aces face the New York Liberty in a regular-season WNBA game at Barclays Centre, with the result set by the final score including overtime. The 19% crowd-implied YES price looks low against the recent head-to-head record, but it is not out of line if the market is effectively pricing a Liberty win as the base case and the YES side is the Aces. New York beat Las Vegas 87-76 on 23 June, then won the Commissioner’s Cup final 93-85 on 30 June, before the Aces edged the Liberty 104-99 on 30 July, so the series has been tight but not one-sided.[1][3][7]

For a power-user setting this up in a bot or conditional-order workflow, the useful inputs are team news, venue, and whether the contest is still on the board by tip-off. ESPN lists the Aces at 22-10 and 13-5 away, with the Liberty 19-13 and 10-5 at home, while both teams have been scoring near 90 points per game, which keeps live-probability updates sensitive to early foul trouble or shooting variance.[4][8] The most relevant operational catalysts are injury or rest announcements, any schedule shift, and whether the game is postponed rather than cancelled, because postponement keeps the market open until completion, whereas cancellation would force a 50-50 resolution under the rules.[4][8][13]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
