Los Angeles FC vs. Seattle Sounders FC - More Markets

Active sub-markets

Market context

Los Angeles FC and Seattle Sounders FC are scheduled to meet on 24 May at 9:00 PM ET in an MLS regular-season fixture. The prediction market currently reflects a 19% implied probability for the "more markets" contract, which typically signals secondary betting opportunities or additional market depth becoming available for this matchup.

Historical MLS matchups between these two Pacific Division rivals show competitive balance, though LAFC has held a slight edge in recent seasons. The 19% probability sits notably below typical sportsbook odds for ancillary markets on major MLS fixtures, suggesting either low expected liquidity or sparse trading activity. Comparable May-scheduled MLS games on prediction markets have generally settled with higher probabilities when secondary markets materialise, particularly for matches involving established franchises with consistent media coverage and betting interest.

Traders should monitor team news regarding injuries or roster changes in the weeks preceding the fixture, as these often trigger sportsbook market expansion. LAFC's fixture congestion in the lead-up to late May—including potential cup commitments—could affect squad rotation decisions and thus the appetite for extended betting markets. Seattle's performance trajectory through May will also influence whether bookmakers deem additional markets commercially viable. Settlement occurs 25 May at 01:00 UTC, allowing only a narrow window post-match for market resolution. Current divergence between the 19% prediction-market probability and typical sportsbook treatment of MLS secondary markets warrants close attention to actual market availability announcements.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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

Where can I trade this market with the lowest fees?

On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

Is this market available outside the US?

PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.

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 PolyGram?

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