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

Platform comparison

Market context

Polymarket is pricing Team Yandex vs Nigma Galaxy at 61% YES for Team Yandex on a Bo3 in the The International play-offs, with settlement tied to the result before the window closes at 17:00 UTC on 21 August. On Polymarket, the contract is backed by USDC on Polygon and settles through conditional tokens, so the practical question is whether the series is played and who wins it within the listed deadline.

The 61% line is consistent with a slight favourite rather than a commanding one. Nigma Galaxy entered the play-offs directly from the group stage, while Team Yandex had to come through the elimination stage, where they beat LGD Gaming 2-1 to secure the final play-off slot. Yandex also reached this match after winning their first play-off series, which supports why the market has not pushed them into a much lower price despite the tougher route. The event itself is the upper bracket semifinal set for 21 August at the Shanghai main event, with all play-off matches except the grand final played as Bo3.

Traders will mainly watch official bracket timing and any rescheduling, because a postponement only keeps the market open if the match is moved to a start time on or before 4 September 2026 at 23:59 ET. A cancellation or a match not played at all resolves to 50-50, which matters in a live event where delays or venue changes can alter settlement even if the underlying pairing stays the same.

Methodology

This page is a comparison snapshot: one live quote, 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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

UK Frequently Asked Questions

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Kalshi UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.
