FC Cincinnati vs. Inter Miami CF

Platform comparison

Market context

FC Cincinnati will host Inter Miami CF in a Major League Soccer fixture on Wednesday, 13 May 2026. The 62% implied probability reflects a slight favoring of Cincinnati as the home side, though the settlement window closes at 23:30 UTC that evening, allowing only the match result to determine the outcome.

Historical MLS home-field advantage typically ranges from 55–65% win probability depending on squad strength and form trajectory. Cincinnati's home record and Miami's away performance across the 2025–26 season will anchor the baseline for this probability. Comparable mid-week fixtures in MLS show tighter margins than weekend matches, partly due to fixture congestion affecting squad rotation and player availability. Traders should cross-reference both teams' recent results, injury reports, and their positions in the playoff race as of early May 2026, as desperation or complacency can shift outcome likelihood materially.

Key catalysts include team news releases on squad fitness in the 48 hours before kick-off, any late-season managerial changes, and confirmation of starting lineups roughly 90 minutes before match time. Weather conditions in Cincinnati on match day may also influence play style. For programmatic approaches, conditional orders tied to lineup announcements or injury confirmations can capture probability shifts. The tight settlement window (match day only) means real-time data feeds on team sheets and pre-match betting movements will be critical for detecting mispricings relative to the current 62% mark.

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

Resolution source: This market settles from the official publication at https://www.mlssoccer.com/schedule/scores. A proposer submits the result to the UMA Optimistic Oracle on Polygon, the two-hour challenge window opens, and the smart contract pays out in USDC.

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.

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'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.

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 PolyGram 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.
