Dota 2: Grind Back vs Carstensz (BO3) - The International Southeast Asia Closed Qualifier Playoffs

Platform comparison

Active sub-markets

Market context

Polymarket is effectively pricing **Grind Back at 100%** on the conditional token contract today, so the market is treating a straightforward win as almost fully reflected in USDC terms on Polygon. In practical trading terms, that leaves very little room for fresh information unless the status changes to a no-contest, delay, or other settlement edge case under the market rules.

That reading is best set against the recent head-to-heads: Carstensz beat Grind Back **2-1** in the SEA closed qualifier on 4 June, while Grind Back later took a **2-1** win in another meeting listed on SofaScore and related results pages. Earlier comparable fixtures between the same two sides have therefore swung both ways, which matters because a 100% quote is less a view on team strength than a statement that the contract is already being priced as effectively locked.

For traders, the key catalysts are not abstract form lines but *operational* updates: whether the Bo3 starts on the published schedule, whether bracket timing shifts, and whether the result is recorded cleanly before the settlement window closes. The market resolves to **50-50** if the match is not played, ends tied, or is delayed beyond seven days without a winner, so any announcement from tournament organisers or a change in broadcast/live score status is more relevant than pre-match chatter.

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.
