Market context
Aurora face Team Liquid in a best-of-one Dota 2 match at the BLAST Slam Group Stage on 28 May at 6:20 AM ET. The Polymarket conditional token pair currently prices Aurora's victory at roughly 10 cents per share, implying a 10% win probability. This valuation reflects Team Liquid's established competitive standing within professional Dota 2, though the early morning scheduling and group-stage format create execution variables that shape how traders should interpret the on-chain pricing across USDC settlement on Polygon.
Team Liquid has maintained roster consistency and qualified for major tournaments throughout 2024 and early 2025, whereas Aurora's recent competitive record shows inconsistent results against tier-one opponents. Historical precedent from BLAST Slam events suggests that established organisations like Liquid convert group-stage fixtures into wins at rates exceeding 85% when facing less-proven challengers. The 10% probability assigned to Aurora reflects appropriate scepticism about their upset potential, though single-elimination formats and early-morning timing have occasionally produced unexpected outcomes in esports betting history.
Traders should monitor team announcements regarding player availability and any schedule adjustments in the 48 hours preceding the match. BLAST Slam's format typically enforces strict timing, reducing the likelihood of significant delays that might trigger the 50-50 resolution clause. Confirmation of both rosters and any last-minute stand-in declarations would represent the primary catalyst affecting conditional token valuations before settlement.
Methodology
This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to Kalshi UK, which mirrors the Polymarket order book directly.
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.
FAQ
- 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 it cost to trade on Kalshi UK?
- Zero. Kalshi UK routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
- 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.
- Do I need to KYC for this market?
- Not under $1,500 of lifetime trading volume. Above that threshold, Kalshi UK triggers a quick verification flow that finishes in minutes.
- 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.
