Dota 2: RE.Arise vs Ilbirs eSports (BO3) - Asgard Championship Playoffs

Platform comparison

Market context

RE.Arise and Ilbirs eSports are into the Lower bracket round 1 clash with the series already live and level at 1-1, which is the key change over the past day for the market. Sofascore and other live trackers show the BO3 began on 9 August at 18:10-18:15 UTC, so the path to a straight match result is now much clearer than when the market was still pricing only the scheduled start. [1][2][8]

The 100% YES price is best read against the recent head-to-head and the broader playoff context rather than as a fresh forecast. Polymarket’s own market context notes RE.Arise beat Ilbirs 2-1 in the group stage on 1 August, while later match listings show a completed 2-0 RE.Arise win in the same tournament record set, which points to the pair having already met in official play this week and supports why traders have been treating the matchup as closely watched. [5][7][14] Strafe also lists this as their first recorded meeting in one dataset and shows the market leaning to Ilbirs on community votes, underlining that pre-match opinion was not one-sided despite the current market’s certainty. [3]

The main catalysts now are operational rather than predictive: whether the third game is completed, whether there is any technical pause or restart, and whether the final result is posted promptly before the settlement window closes on 10 August at 00:15 UTC. Tournament schedule pages still place the bracket matches on 9 August, with RE.Arise vs Ilbirs listed as part of the playoff slate, so any delay in official scoring or an incomplete series would matter more here than a change in form.

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

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.
