Boston Legacy FC vs. Washington Spirit

Platform comparison

Market context

Boston Legacy FC lost 1–2 to Washington Spirit in their NWSL match on Sunday, 19 July 2026, a result that has already settled the underlying event. On Polymarket, the YES contract for this outcome now trades at 0% probability, reflecting the final score and the closure of the settlement window. The market uses USDC on Polygon, where conditional tokens automatically resolve once the official result is confirmed, locking in the loss for any remaining YES holders.

Historically, NWSL prediction markets with 0% crowd-implied probability before settlement rarely reverse once the match concludes, as the league’s official scoreline is the sole settlement criterion. Comparable cases from the 2024 and 2025 seasons show that once a game ends, conditional tokens resolve within minutes, with no further catalysts able to alter the outcome. The 0% price here is not a speculative view but a mechanical reflection of the final score, mirroring past instances where post-match markets instantly corrected to 0% or 100%.

Traders should monitor the NWSL’s official match report and ESPN’s final score confirmation, which both list Washington Spirit as the 2–1 winner [1][2]. No further announcements, schedule changes, or dependencies can affect this market, as the settlement window ended at 23:00 UTC on 19 July. The only relevant dependency was the match itself, now complete, meaning the contract’s resolution is final and irreversible on-chain.

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.

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 does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
