Dota 2: PlayTime vs Execration (BO3) - Games of the Future Playoffs

Platform comparison

Market context

PlayTime are playing Execration in a best-of-three playoff match at Games of the Future, and the live listing had the series underway at 0–0 from 05:00 UTC, which is why a 0% crowd-implied YES looks more like a stale or mispriced tape than a live read on the game state.[2][4][5] For a bot or trader wiring this into a workflow, the key input is whether the market is meant to follow the scheduled start, the live score feed, or the eventual official result; those are different state variables, and this fixture is already showing how easily a pre-start snapshot can become unusable once the match is live.[2][4]

Comparable Dota 2 tools and odds feeds have treated PlayTime as the stronger side, with Strafe showing roughly 87% support for PlayTime and dltv listing PlayTime as the higher-ranked side, while earlier head-to-head data is limited and inconsistent across aggregators.[4][8][10][13] That combination usually means the market should be read as a short-series volatility case rather than a pure ranking arbitrage: in BO3s, a single draft swing, lane mistake, or map-one upset can quickly flip implied probabilities, especially when historical direct meetings are sparse.[4][13][15]

For a programmatic approach, the main catalysts are official bracket updates, the live score feed, and any broadcast or scheduling notices that would affect whether the series completes inside the settlement window.[1][2][4] If the match is interrupted, delayed, or left unfinished, the market’s resolution rules become more important than the in-game favourite, so a bot should monitor for start-time slippage, series abandonment, and whether a completed winner is recorded before the seven-day fallback threshold.[2][5]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

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 Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Bot UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
