Valorant: 100 Thieves vs Cloud9 (BO3) - VCT Americas Stage 2 Group Omega

Platform comparison

Market context

100 Thieves and Cloud9 were scheduled to play a best-of-three in VCT Americas Stage 2 Group Omega on 7 August, and the market is still trading as if 100 Thieves are the clearer side despite the current crowd-implied 0% yes price. The live scheduling feeds place the match around 10:00 PM UTC / 5:00 PM ET, so the immediate question for traders is whether it has started, finished, or slipped far enough to force a void-style 50-50 settlement under the market rules.[2][3][13]

Recent form and head-to-head context both lean towards 100 Thieves. Strafe’s match page says 100 Thieves had won 4 of their last 5 matches, Cloud9 only 1 of 5, and 100 Thieves led the all-time series 5-4, with the latest meeting ending 2-1 to 100 Thieves on 13 February 2026.[2] Other preview markets and community pages also show 100 Thieves favoured for the series, with most scoreline models clustering around a 2-0 or 2-1 result rather than a Cloud9 sweep.[4][5][16]

For a trader, the key catalysts are simple: confirm whether the series is on stream, whether any delay pushes it beyond the settlement window, and whether either side fields a different roster than expected. The Spikes and schedule listings still place the fixture in the Group Omega slate alongside other Stage 2 matches, while some aggregators show only generic live-score placeholders rather than a completed result, which matters because an abandoned or unplayed match would not resolve to a side win.[3][7][13]

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%.
