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

Platform comparison

Market context

Aurora and Team Yandex face off in a best-of-three Dota 2 match during The International's group stage on 14 August 2026, with Aurora priced at 37% on Polymarket's USDC contract on Polygon. The match begins at 4:00 AM ET, positioning it in an early window that may affect viewership and betting liquidity as traders across time zones react to live results. Settlement occurs at 16:20 UTC the same day, with conditional tokens resolving based on match outcome—Aurora victory triggers YES tokens, Team Yandex victory triggers NO tokens, whilst cancellation or ties split the pot evenly.

Historical precedent suggests CIS-region teams (Team Yandex's base) have performed inconsistently at The International's group stages over recent iterations, with qualification depth varying significantly year-to-year. Aurora's recent LAN placements and meta adaptation heading into the tournament will heavily influence whether the 37% probability reflects genuine competitive disadvantage or market mispricing. The International's format typically sees early group-stage matches produce fewer upsets than later stages, as seeding generally correlates with performance.

Key catalysts include official roster confirmations and any last-minute schedule adjustments announced by The International organisers. Traders should monitor pre-match patch notes released within 48 hours of play, as hero balance changes can disproportionately favour one team's draft pool. Any postponement triggers the 14-day rescheduling window (ending 28 August 2026 at 23:59 ET), during which the contract remains open but unsettled, creating extended exposure for USDC holders on Polygon.

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.

UK Frequently Asked Questions

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.

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%.
