Market context
No Hoodwink face RE.Arise in a Dota 2 lower bracket semifinal at the Asgard Championship Playoffs on 10 August at 12:00 PM ET. The winner advances to the lower bracket final; the loser is eliminated from the tournament. Both teams compete in the professional Southeast Asian Dota 2 circuit, where roster stability and recent LAN performance heavily influence match outcomes. The current 100% implied probability for a match occurring reflects the standard assumption that scheduled professional esports fixtures proceed as planned, barring unforeseen circumstances.
Historical precedent suggests that cancellations or no-contests in tier-two regional Dota 2 tournaments occur in fewer than 2% of scheduled matches, typically only when visa complications, equipment failure, or severe illness affects a competing roster. The Asgard Championship maintains a reliable fixture record; no lower bracket matches from the 2024 season were postponed beyond the seven-day threshold. RE.Arise and No Hoodwink both fielded complete rosters at the group stage, indicating no immediate personnel issues that would jeopardise the fixture.
Traders should monitor team announcements for last-minute roster changes or health disclosures in the 48 hours preceding the match. The settlement window closes at 22:00 UTC on 10 August, allowing approximately ten hours after the scheduled start time for the best-of-three to conclude. Any delay extending beyond 17 August without a decisive result triggers the 50-50 resolution clause. Venue confirmations and broadcast schedules from the Asgard Championship official channels will clarify fixture timing; delays have been rare but occurred once in 2023 due to internet infrastructure issues at the host facility.
Methodology
Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — sit alongside as off-chain reference points so you can see how the contract translates across regulatory and settlement regimes.
Resolution & payout
Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.
Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.
UK Frequently Asked Questions
- What are crypto prediction markets?
- Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.
- What does a transaction cost on Polygon?
- Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.
- Is Polymarket legal in the UK?
- Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.
- Do I pay tax on prediction market profits in the UK?
- UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.
- How do I deposit on Polymarket from the UK?
- UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
