Dota 2: KW vs RE.Arise (BO3) - EPL Masters Group B

Platform comparison

Market context

KW’s Dota 2 series against RE.Arise in EPL Masters Group B was priced very differently across venues, with the prediction market sitting at **0% YES** while a live sportsbook-style listing had RE.Arise around **74%** and KW around **26%**. That split is large enough to matter: the crowd price on the contract is effectively implying the match outcome is already beyond reach, whereas the external market still treats RE.Arise as the clearer favourite rather than a lock.[4][6]

The historical read-through is mixed but leans towards KW as the more supported side in community previews. Strafe users backed KW with **66.7%** of votes, while DLTV’s match page showed RE.Arise with a **75%** winrate tag versus KW’s **46%**, alongside stronger first-blood and first-10-minute indicators for RE.Arise.[1][5] Polymarket’s own market page showed substantial activity, with about **$140.78K** in volume and the contract already reflecting an extremely skewed view of the result before settlement.[2] For traders, that means the key question is not simply which team is stronger, but whether the market’s 0% price reflects a confirmed live result, a data feed issue, or an outcome that has effectively locked in elsewhere.[2][6]

The main catalysts now are official match completion, any score confirmation from the tournament organiser, and whether the series was fully played as a best-of-three or ended via forfeit, disqualification, or walkover, since those settlement paths can override an unfinished on-screen score. Bo3.gg’s live page already showed a completed-series format with a final score scaffold, which is the kind of signal that usually drives rapid repricing if mirrored by the organiser feed.[3] Traders should watch for bracket updates, streamer or scoreboard confirmation, and any late notice about postponement or abandonment, because if the match was not completed in the required form, the contract can still resolve away from the apparent in-game winner.[3][6]

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

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.

Do I need to KYC for this market?

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

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.
