Market context

InterActive Philippines are due to face Mentality Monster in a best-of-three lower-bracket playoff match in the Southeast Asia closed qualifier for The International, with the result deciding who stays alive in the regional route to TI. The market’s crowd-implied 0% Yes price points to an extreme view that the labelled team is effectively not expected to advance, although the live bracket context still matters because playoff Dota can swing quickly on draft quality and one decisive map.[3][8]

For context, the teams have already been listed against each other in qualifier coverage, with third-party match pages showing the same pairing in June 2026 and multiple qualifier broadcasts featuring InterActive Philippines in the TI regional event window.[1][2][5][8] In prediction-market terms, low or zero pricing on an esports elimination match often reflects either strong form asymmetry or a belief that the fixture will not resolve on schedule; that matters here because settlement is tied to the match outcome, but a cancellation, tie, or a delay beyond seven days would change the resolution path.

A trader watching this market should track official tournament scheduling, bracket updates, and any broadcast or organiser announcements that affect whether the series is actually played and completed within the settlement window.[2][3] From a regulatory and access angle, German GlüStV restrictions can affect whether residents can use gambling-adjacent services, while US CFTC reach is relevant if a platform or participant is viewed as operating within US derivatives rules; separately, “no-KYC up to $1,500” means smaller users may access the market with limited identity checks, but higher-volume activity can still trigger verification and is not the same as unrestricted access.

Methodology

We track Dota 2: InterActive Philippines vs Mentality Monster (BO3) - The International Southeast Asia Closed Qualifier Playoffs on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
