Pronóstico: Boston Legacy FC vs. Washington Spirit

Platform comparison

Market context

Boston Legacy FC and Washington Spirit played their NWSL match on Sunday, 19 July 2026, with Washington securing a 2–1 victory. On Polymarket today, the contract for “Boston Legacy FC wins” trades at 0% YES, reflecting the settled outcome rather than pre-match uncertainty. The market resolves on-chain using USDC on Polygon, where conditional tokens now lock in the final result as the settlement window closes at 23:00 UTC on 19 July.

Historically, NWSL prediction markets with 0% implied probability after match completion show near-zero volatility, as conditional tokens simply redeem at full value for the winning side. Comparable cases from 2024–2025 NWSL games confirm that once a result is official, prices collapse to 0% or 100% within hours, with no meaningful re-trading. The Washington Spirit’s -135 odds pre-match and their actual 2–1 win align precisely with this pattern, making the 0% price a mechanical certainty rather than a speculative signal [2][3].

Traders should monitor the official NWSL result confirmation on ESPN and Fox Sports, both of which already list the final score and goal details [2][3]. No further announcements, schedule changes, or dependencies remain, as the match has concluded and the settlement window is active. The only catalyst is the final on-chain resolution, which will automatically distribute USDC to holders of the winning conditional token once the 2026-07-19T23:00:00Z deadline passes.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
