Dota 2: Execration vs Mentality Monster (BO3) - The International Southeast Asia Closed Qualifier Playoffs

Platform comparison

Active sub-markets

Market context

Execration’s lower-bracket meeting with Mentality Monster is a best-of-three elimination match in the Southeast Asia closed qualifier, so the main market question is simply who advances rather than who wins a map or two. With the crowd-implied price at 50%, the contract is effectively treating the series as close to even, which is consistent with the absence of direct head-to-head history between the sides and the uncertainty that often surrounds qualifier brackets.[3]

Comparable context leans slightly towards Execration being the more established regional name. Polymarket’s market description notes that Execration arrived with stronger SEA pedigree, a direct invite, and a recent 2-0 over Carstensz Esports, while Mentality Monster came through open qualifiers with a reported 59% recent win rate but less evidence against higher-tier opposition.[2] That sort of split usually supports a narrow favourite rather than a clear one, especially in a BO3 where draft adaptation and side-selection can swing the series.

For traders, the key catalysts are whether the scheduled lower-bracket slot actually starts on time, whether the bracket runs without rescheduling, and whether any upstream match delays push the series beyond the seven-day settlement grace period, which would force a 50-50 outcome under the market rules.[2] On-chain, the practical angle is that USDC settlement is only resolved once the event outcome is final, so market repricing will mostly track bracket confirmations rather than any crypto-beta signal; if broader BTC or ETH volatility spikes, it matters more through risk appetite than through the esports result itself.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — are listed with their platform attributes, because they operate off-chain and a 1:1 comparison of contract mechanics isn't possible.

Resolution & payout

Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.

Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.
