Market outcomes
| Colorado Rapids SC | 0% YES | 100% NO |
| Draw | 0% YES | 100% NO |
| St. Louis City SC | 100% YES | 0% NO |
Colorado Rapids SC will host St. Louis City SC on 9 May 2026 at 9:30 PM ET in an MLS regular season fixture. The market settles on the halftime result—whether Colorado wins, the sides draw, or St. Louis wins within the first 45 minutes plus stoppage time. The current 0% YES probability on Polymarket's order book reflects no trading activity supporting a Colorado halftime victory, suggesting either illiquidity in this specific market segment or strong consensus against early Rapids dominance.
Halftime markets in MLS typically reflect team attacking patterns and defensive vulnerabilities established over preceding seasons. Colorado's historical tendency to build pressure gradually rather than dominate early phases would contextualise a low probability for a home halftime lead. St. Louis City, having entered MLS in 2023, demonstrated defensive solidity in their inaugural campaign, which often translates to cautious opening periods. Comparable MLS halftime markets show draws and away results command higher liquidity when home sides lack explosive early-game records.
Traders should monitor team news through early May, particularly injury status for key attacking players on either side and any tactical announcements from managers. Weather conditions at Dick's Sporting Goods Park—altitude and wind patterns—can affect early-game play. Recent fixture congestion in the MLS schedule leading into this match may influence starting lineups and intensity levels in the opening 45 minutes. Confirmation of final squad lists typically arrives 24 hours before kickoff.
This market settles from the official outcome published at https://www.mlssoccer.com/schedule/scores. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
The mechanics for trading "Colorado Rapids SC vs. St. Louis City SC - Halftime Result" are the same as any other PolyGram sporting event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$407 in lifetime turnover and $0 of resting liquidity puts this market in the below the median by volume for sports contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
