Market context
The United21 Group C decider between Alpha Dominion Nation and Alpha Gaming is set to begin at 4:00 AM ET today, with the crowd-implied probability sitting at a precise 50% for Alpha Dominion Nation to win the Best of 3 series. This equilibrium is starkly contradicted by external sentiment; Strafe users overwhelmingly favour Alpha Gaming with an 89.7% vote share, while Robinhood markets price Alpha Gaming at 54¢ against Alpha Dominion Nation’s 48¢. Such divergences between on-chain pricing and community polling are common in lower-tier esports, where liquidity is thin and conditional tokens on Polygon often lag behind real-time form.
Historically, similar Group C deciders in the United21 circuit have resolved with the underdog winning when external polls suggest a heavy favourite, as seen in the June 21 match where INFURITY Gaming secured a verified victory despite mixed pre-match signals. The 50% price point here likely reflects the cancellation clause, which forces a 50-50 resolution if the match is delayed beyond seven days or ends in a tie, creating a safety floor that anchors the price despite the 89.7% external bias. Traders should watch for the live score update on Profilerr, which currently shows Alpha Dominion Nation leading 1-0, and monitor HLTV for any official delay announcements that could trigger the settlement clause.
The primary catalyst for this market is the immediate progression of the live match, as the current 1-0 lead for Alpha Dominion Nation could rapidly shift the implied probability if Alpha Gaming fails to close the gap. A recent update from Strafe confirms the match is a Best of 3 series, meaning the second game is critical for determining the final outcome. Traders must also verify the USDC settlement window, which closes at 14:30 UTC on 24 June, ensuring that any on-chain conditional tokens reflect the final result before the deadline. The market remains sensitive to any delay notifications, as the seven-day rule provides a distinct resolution path that currently justifies the 50% price despite the heavy external bias towards Alpha Gaming.

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