Dota 2: Team AION vs Dandelions (BO3) - EPL Masters Play-In Group B

Platform comparison

Market context

Team AION’s meeting with Dandelions in the EPL Masters Play-In is live on the schedule, and the market has already moved to a 0% YES line despite the match still being due on the day. That pricing reflects a strong lean towards Dandelions rather than any sign the series has been removed from play; with the settlement window tied to the scheduled start and a BO3 format, the main question is whether the series begins and reaches a clean finish.

The small amount of comparable context points in the same direction. Strafe’s user vote is heavily one-sided, with Dandelions attracting 88.9% and 92.3% of votes in two language versions of the listing, while BO3.gg also shows predictive score splits centred on a Dandelions win rather than a Team AION upset.[2][4][1][3] Ensigame likewise describes Team AION as entering with a 0% recent win rate and Dandelions with a materially better recent record, which helps explain why the crowd has not assigned meaningful win probability to Team AION.[6]

For traders, the key catalysts are operational rather than strategic: confirmation that the series starts on time, whether the bracket remains intact, and whether any late roster or schedule changes appear before the window closes. The settlement rules also matter because a cancellation, tie, or delay beyond seven days would not produce a normal winner outcome, while an unfinished map with a forfeit decision would still resolve to the side awarded the match. That means the market can only settle decisively if the series is actually played to a result within the permitted timeframe.

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.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.
