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

Platform comparison

Active sub-markets

Market context

Execration’s lower-bracket semifinal against Grind Back in the Southeast Asia closed qualifier is the kind of BO3 that tends to hinge on draft quality, lane stability and whether either side can convert early map control into clean series wins. For a programme that tracks markets mechanically, the key is that this is not a best-of-one volatility spot: the team that takes the first map still has to close out a second, so live models usually weight side selection, tempo line-ups and substitution news more heavily than raw pre-match sentiment.

The crowd is currently pricing a complete conviction outcome at 100% YES, but comparable qualifier markets have often moved sharply once line-ups are confirmed and the first draft appears. A useful reference point is the live match context on Dotabuff and CryptoSlate’s market view, which shows Grind Back as the market favourite at 82.5% and Execration at 17.5% in the same fixture, underlining that sentiment can diverge materially across venues and update cycles.[1][8] For conditional-order style approaches, that gap matters because a late reversal in map odds can still be driven by one coach ban phase or one roster change rather than the broader pre-match price.

The practical catalysts are simple: official start-time confirmation, any schedule slippage from the qualifier organiser, and whether the series actually begins before the settlement window closes at 2026-06-22T19:50:00Z. Polymarket’s own resolution rules also matter operationally: if the match starts but is not completed, or if it is abandoned after beginning, the outcome depends on the final state rather than the pre-match favourite.[2] For traders using bots or trigger-based entries, the safest checks are event-page updates, live bracket status and broadcast start signals, because a delayed lower-bracket match can still resolve cleanly if it starts within the window, but can flip to a 50-50 outcome if it is cancelled or pushed too far back.[2]

Methodology

This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Polymarket Review UK, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does it cost to trade on Polymarket Review UK?

Zero. Polymarket Review UK routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
