Dota 2: RE.Arise vs Spirit Academy (BO3) - European Pro League Playoffs

Platform comparison

Market context

The real-world event is a Best of 3 Dota 2 match between RE.Arise and Spirit Academy in the European Pro League Playoffs, scheduled for 9 July 2026 at 10:10 UTC. In prediction markets, a YES share pays out if the market resolves to RE.Arise winning, while a NO share pays out if Spirit Academy wins or the match is cancelled. This specific market currently shows a 100% crowd-implied probability for RE.Arise, suggesting the crowd believes a Spirit Academy victory is virtually impossible.

Historically, such extreme probabilities in esports often precede a mismatch where one team dominates the other, yet they can also signal a fragile consensus if key variables shift. In the recent European Pro League Season 39, Spirit Academy defeated RE.Arise 2-0 on 2 July 2026, contradicting the current 100% sentiment for RE.Arise in this playoff match[3]. This prior result highlights that while RE.Arise holds a higher world ranking (35 vs 69), the teams have shown competitive volatility, making the current 100% probability a point of scrutiny for traders[5].

Traders should monitor the official match start time and any live score updates, as delays or cancellations would reset the market to a 50-50 outcome. The match is live now, with RE.Arise leading on the scoreboard, which may reinforce the YES position if the lead holds[2]. Any announcement regarding roster changes or schedule adjustments from the European Pro League organisers would be a critical catalyst, as these dependencies directly determine the final resolution of the contract[4].

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.
