Dota 2: Aurora vs GamerLegion (BO3) - The International Group Stage

Platform comparison

Market context

Aurora and GamerLegion are scheduled to compete in a best-of-three Dota 2 match during The International Group Stage on 13 August at 01:00 ET. The fixture forms part of the tournament's opening round, where teams contest for seeding advancement and early momentum. Settlement occurs at 12:10 UTC on the same date, allowing a narrow window for match completion and resolution confirmation. The market structure permits 50-50 resolution only if the match fails to conclude within seven days or is cancelled outright, a rare occurrence at The International given Valve's operational consistency.

Historical precedent suggests near-certainty pricing on scheduled International matches reflects genuine fixture reliability rather than overconfidence. Across prior International tournaments, group-stage cancellations have been negligible; technical delays occasionally extend matches beyond their scheduled slot but rarely prevent completion. GamerLegion's participation as a qualified roster and Aurora's confirmed attendance reduce no-show risk substantially. The 100% implied probability reflects the binary nature of esports settlement—matches either occur and produce a winner, or trigger the tie-resolution clause.

Traders should monitor official Dota 2 and The International social channels for any last-minute roster changes, technical issues, or schedule adjustments in the 48 hours preceding the fixture. Visa complications or player illness have historically caused International withdrawals, though such events typically surface well before match time. USDC settlement mechanics on btc-prediction.bet remain contingent on Valve's official match result publication; funding rates on crypto derivatives markets show no material correlation to esports outcomes, making macro positioning irrelevant to this specific contract.

Methodology

This page reads Dota 2: Aurora vs GamerLegion (BO3) - The International Group Stage on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

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 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.

Can I use Bitcoin directly?

No, Polymarket operates exclusively in USDC on Polygon. You can bridge BTC to USDC via an exchange or bridge service and deposit on Polygon — typically 10-30 minutes processing time.

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%.
