Chicago Sky vs. New York Liberty

Platform comparison

Market context

Chicago Sky and New York Liberty are scheduled to meet in a WNBA game with the market set to resolve on the final score, including overtime, so the cleanest programmatic read is simply a moneyline-style binary on the winner, with postponement keeping it live and a cancellation forcing a 50-50 split. With crowd-implied YES at 28%, the market is pricing a Liberty win as the base case, not a coin flip, which is consistent with how automated models usually treat a strong favourite in a one-game settlement window.

Recent comparable pricing also points that way: ESPN’s pregame line listed the Liberty as 10.5-point favourites with a 178.5 total, while earlier June previews showed spreads around Liberty -9.5 to -11.5 and moneylines as steep as -526, all of which imply Chicago would need to outperform the market by a wide margin to win outright. In tooling terms, this is the sort of event where copy-traders and bot runners usually key off the pregame spread and any late injury adjustment, because the market’s 28% YES sits below what a simple favourite-to-win conversion would often suggest.

The main catalysts are final injury status, official starting line-ups, and any schedule drift before tip-off, because a postponement keeps the contract open until the game is played. For a bot, the practical checks are the league’s game status feed, sportsbook line movement, and any late roster news that changes the spread or moneyline; if the game starts on time, the settlement risk is mostly about whether Chicago can close as an underdog rather than about ambiguity in the rules.

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

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.
