Dota 2: Team Yandex vs Nigma Galaxy (BO3) - The International Playoffs

Platform comparison

Market context

Team Yandex meet Nigma Galaxy in the upper-bracket semi-final at The International playoffs, with the series scheduled as a best-of-three and the market set to resolve before the 17:00 UTC settlement cut-off. The current 61% implied price leans towards Yandex, which fits a spot where they have already beaten Team Liquid 2-0 to reach this round, while Nigma arrived here as one of the higher-seeded playoff sides. [6][14][13]

That probability is best read as a modest favourite rather than a lock. In TI playoff brackets, best-of-three volatility is high: one draft edge, lane result, or Roshan fight can swing the whole series, and the eventual path changes quickly because the winner advances towards the upper-bracket final while the loser is pushed into the lower bracket. The market also carries the usual on-chain settlement features of a USDC market: if the match is played cleanly, the result should settle to the listed winner; if it is not played or ends level, it falls to 50-50 under the contract rules. [13][3][14]

Traders should watch for any start-time changes, broadcast confirmations, or bracket rescheduling from the organiser, because TI’s in-arena playoff slate runs across 20-23 August in Shanghai and the published schedule for 21 August places upper-bracket semi-finals after the early lower-bracket matches. If the series slips, the contract allows postponement only within the stated window, so timing matters as much as the matchup itself. Broader crypto conditions can still filter in at the margin: BTC and ETH spot risk appetite, funding-rate shifts, and large exchange flows can affect USDC market liquidity, but they do not change the match result.

Methodology

This page reads Dota 2: Team Yandex vs Nigma Galaxy (BO3) - The International Playoffs 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 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.

Why USDC and not ETH or USDT?

USDC is the Polygon standard — audited reserves (Circle, monthly attestation), deepest order book, low gas costs. ETH volatility would distort probability quotes; USDT has thinner Polygon liquidity than USDC.

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%.
