Market context
Infinite and 100 Thieves are due to meet in a best-of-three at the Esports World Cup Open Qualifier Play-Ins, with the match listed for 09:00 and the market set to resolve on the scheduled result, or to 50-50 if the game is not played or is left without a winner under the stated timeout rules.[1][12] The crowd-implied **28% YES** price is below Bitget’s live read of roughly **23% Infinite / 78% 100 Thieves**, which suggests the market has already leaned towards 100 Thieves rather than pricing the fixture as close to even.[9]
For context, this is an online qualifier stage with broader tournament implications: the Open Qualifier is a B-tier CS2 event running over 9 August, with regional squads playing for ranking points and access to larger events, and the listed bracket places this tie in the Round of 32/Play-Ins.[1][8][12] That matters for accessibility and settlement risk because online qualifiers are more exposed to schedule slippage, lobby issues, and late bracket changes than main-stage LAN fixtures. On market venues serving UK users, the practical appeal is also shaped by compliance: German-style GlüStV restrictions can affect whether a user can participate from a given jurisdiction, while US CFTC reach matters because sports-style event contracts may be unavailable or constrained for US-facing traders; a “no-KYC up to $1,500” threshold typically means a user can access and settle smaller positions without full identity verification, but withdrawals and cumulative limits still depend on the platform’s own controls.

UK Frequently Asked Questions
- Is Polymarket legal in my country?
- Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Tax UK has a different geo footprint.
- Is Polymarket regulated by the UKGC?
- No. Polymarket is not licensed by the UK Gambling Commission (UKGC). It is a decentralised prediction market operated under US regulation. UK traders can use it but do not benefit from UKGC dispute resolution or player protection requirements.
- What are the HMRC tax rules on Polymarket profits for UK traders?
- Polymarket profits are treated as cryptocurrency disposal events by HMRC. Each USDC settlement is a taxable event subject to Capital Gains Tax (CGT). For 2026/27, the CGT rate is 18% (basic rate) or 24% (higher rate). The annual CGT exemption is £3,000. Report via HMRC Self Assessment if your total crypto gains exceed £3,000 or proceeds exceed £50,000.
- Does Polymarket KYC apply to UK users?
- Yes. Polymarket requires KYC (Know Your Customer) verification for all users, including UK residents. You must provide a government-issued photo ID and a selfie. The process typically takes 5–10 minutes via their ID verification provider.
- What is the legal difference between Polymarket and Betfair Exchange for UK traders?
- Betfair Exchange is UKGC-licensed, meaning UK consumer protections apply and winnings are typically tax-free. Polymarket is not UKGC-licensed — it operates under decentralised blockchain rules. Profits from Polymarket are subject to HMRC CGT as crypto disposals. Choose based on your regulatory preference and tax situation.
