Inter Miami CF vs. Chicago Fire FC

Platform comparison

Market context

Inter Miami’s meeting with Chicago Fire FC is a live MLS fixture, and the market’s 40% yes price sits below a simple exchange-implied midpoint because this matchup has recently produced both narrow and high-variance outcomes. Chicago held Miami to a 0-0 draw in April 2025, while earlier meetings included a 3-1 Chicago win in 2022 and a 4-1 Fire win in 2023, so the historical read is not one of stable dominance but of match state swinging sharply with line-up strength and game script.[5][3][2]

For a power user running this through a bot or conditional-order stack, the key inputs are team-sheet timing, travel and rest, and whether either side rotates late in the schedule. Programmatically, this is the sort of market to watch for line-up confirmations, late injury or suspension flags, and any price drift around kick-off as fresh information hits; third-party live odds services currently model Miami as a slight favourite, with an average win probability of 42% versus 34% for Chicago and 24% for the draw, which is broadly consistent with a low-to-mid conviction position rather than a lock.[1] Because the market settles at 23:30 UTC, any late team news before the final whistle can matter materially if your workflow relies on automated entry or exit thresholds.[4]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Review UK, which mirrors the Polymarket order book directly.

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.

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.

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.

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.
