Market context

InterActive Philippines and Mentality Monster face off in the Lower Bracket round 2 of The International Southeast Asia Closed Qualifier Playoffs, a Best of 3 series initially set for 1:00 AM ET on 21 June. On Polymarket, this contract trades at 0% YES for InterActive Philippines, reflecting a near-total market conviction that the Filipino squad will not secure the win, despite their 79% community vote favour in a prior EPL World Series encounter against the same opponent[1].

Historically, such extreme probability divergences often signal underlying integrity concerns rather than pure skill deficits. In tier-2 Dota 2, similar 0% pricing has preceded matches where teams faced allegations of match-fixing or roster instability, as seen in recent Reddit discussions alleging blatant manipulation by InterActive Philippines in lower-tier leagues[6]. When conditional tokens on Polygon are priced this low, traders typically interpret it as a warning of non-performance or cancellation rather than a straightforward competitive loss.

Traders must monitor the official match schedule on Sofascore for any delays beyond the 7-day resolution window, which would trigger automatic cancellation and void the contract[4]. Crucially, watch for Valve’s response to the match-fixing allegations circulating in the community, as an investigation could lead to immediate disqualification or suspension of InterActive Philippines before the game begins[6]. The USDC payout mechanism on Polymarket resolves within an hour of event verification, so any administrative intervention will be reflected instantly in the conditional token settlement.

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.
