LoL: DOCISK vs Forsaken (BO3) - Rift Legends Regular Season

Platform comparison

Market context

DOCISK and Forsaken have already played their Rift Legends regular-season BO3, with DOCISK winning 2-1 on 25 August; that leaves the market’s 0% YES showing out of line with the finished result unless the contract is being held open for a formal replay, cancellation, or settlement delay. With the listed settlement window ending at 00:30 UTC on 26 August, the practical focus is now whether the event is confirmed complete and recognised for resolution, rather than the on-stage outcome itself.

Forsaken had entered the series with stronger recent form and a better head-to-head record, which is the kind of setup that often supports a pre-match favourite in small regional LoL leagues. That said, these markets can move sharply when the match is actually played, because BO3 results in lower-tier competitions are sensitive to draft variance, side selection, and one-sided game states rather than long-run team strength.

The main catalyst to watch is official match reporting: the market description says resolution depends on the match being played, cancelled, tied, or postponed within the permitted window. If the series is fully posted and finalised by recognised results pages, DOCISK should settle as the winner; if there is a dispute over completion, the decisive factor will be whether the organiser or result providers confirm the score before the deadline.

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

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

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%.
