Active sub-markets

Market context

The underlying event is the Upper Bracket quarterfinal 2 match in The International Europe Closed Qualifier Playoffs, where Nigma Galaxy faces Natus Vincere in a best-of-three series scheduled for 1:00PM ET on 23 June. Natus Vincere currently hold a 67% win rate over the last three months, having secured 12 victories from 18 matches, including a decisive 2:0 win against Modus just two days prior[1][5]. Historical head-to-head data between these sides shows NaVi as the consistent favourite, with past encounters often ending in straight sets, framing the current 0% crowd-implied probability for Nigma as a reflection of deep-seated underdog status rather than a market anomaly[2][3]. In comparable TI regional qualifiers, teams with NaVi’s recent form rarely lose to lower-ranked qualifiers unless facing a specific meta shift, suggesting the consensus sits firmly on the Ukrainian side.

Traders should monitor the live score feed for any early map collapses or roster dependencies, as NaVi’s recent schedule indicates they are peaking for this qualifier[5][7]. A key catalyst is the potential for Nigma to exploit NaVi’s aggressive early-game style, which has occasionally led to overextension in Tier 1 matches earlier this month[6]. While no formal roster announcements have been made, the market value may sit on a contrarian angle if Nigma demonstrates superior map control in the first map, as NaVi’s 56% annual win rate suggests vulnerability against disciplined, slower-paced opponents[1]. The settlement window closes on 23 June 2026, and any delay beyond seven days without a winner would trigger a 50-50 resolution, though the match is expected to proceed as scheduled.

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

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.
