Roehampton: Filip Peliwo vs Nicolas Tepmahc

Platform comparison

Market context

The Roehampton qualifying tournament in August 2026 will feature a match between Filip Peliwo and Nicolas Tepmahc, scheduled for 18 August at 08:00 ET. Roehampton serves as a preparatory event ahead of the US Open hard-court season, drawing a mix of ranked professionals and emerging challengers. The current 100% crowd-implied probability suggests near-certainty that one player will advance, though this reflects the binary nature of tennis outcomes rather than exceptional predictive confidence in either competitor's prospects.

Qualifying matches at Roehampton historically show completion rates above 95%, with walkovers and withdrawals accounting for most non-finishes. The tournament's position in the calendar—immediately before the US Open series—means players are typically committed to competing unless injury or illness intervenes. Comparable ATP Challenger qualifying events over the past two years have seen similar settlement patterns, with matches delayed beyond the seven-day threshold occurring in fewer than 3% of cases. The current probability floor reflects this structural reliability rather than market conviction about Peliwo's likelihood of victory.

Traders should monitor player injury reports and entry confirmations through the ATP's official draw releases, typically published five days before the event. Weather disruptions at Roehampton are possible but rarely extend beyond 48 hours given the venue's indoor facilities. The settlement window closes 25 August at 12:00 UTC, providing a week's buffer after the scheduled date. USDC settlement will execute once the ATP confirms the match result through official channels, with no dependency on macro crypto conditions or funding rate movements.

Methodology

Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — sit alongside as off-chain reference points so you can see how the contract translates across regulatory and settlement regimes.

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

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.

What does a transaction cost on Polygon?

Polygon gas is typically under $0.01 per transaction. A full trade cycle (Approve + Order + Fill) totals around $0.03 — compared to $5-50 on Ethereum mainnet.

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%.
