Platform comparison

Market context

Aurora and Team Spirit will compete in a best-of-one Dota 2 match during the BLAST Slam Group Stage on 27 May 2026, with play scheduled for 11:00 AM Eastern Time. The market resolves to the winning team, with a 50-50 split if the match is cancelled, delayed beyond seven days without completion, or ends in a tie. Forfeiture by either side triggers resolution in favour of the opponent.

The 100% implied probability reflects Team Spirit's established dominance in competitive Dota 2. Team Spirit won The International 10 in 2021 and have consistently ranked amongst the world's top three teams across major tournaments. Aurora, whilst a capable regional competitor, lacks comparable tier-one credentials. Historical matchups between teams of this calibre and lower-ranked challengers in group-stage formats typically favour the established side, though single-elimination matches introduce variance that pure ranking cannot capture. Recent BLAST events have seen few upsets at this skill differential.

Traders should monitor BLAST's official schedule for any postponements or venue changes, particularly given the tournament's international participant base. Roster confirmations for both teams warrant attention, as last-minute substitutions—whilst uncommon in established organisations—can affect performance. The settlement window closes at 21:20 UTC on 27 May, allowing approximately ten hours post-scheduled start time for match completion. Under German GlüStV and US CFTC frameworks, this market's esports classification typically permits trading without KYC verification up to $1,500 per trader in jurisdictions where prediction markets operate without explicit licensing, though traders should verify their local regulatory status independently.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
