Cincinnati Open: Marton Fucsovics vs Terence Atmane

Platform comparison

Market context

Terence Atmane’s first-round meeting with Marton Fucsovics in Cincinnati has already been completed, and the market’s 0% YES reads as a stale pre-match price rather than a live view of the result. Tennis.com lists the round-one match as completed with Atmane leading 3-1 when play ended, which is the key real-world event for this contract because a finished match removes most of the settlement ambiguity[2].

Before play, the matchup was one of the more balanced first-round pairings on paper: Atmane was the higher-ranked player, but the head-to-head was level at 1-1 and both previous meetings on hard courts had been straight-set affairs[1]. That mix usually keeps pre-match pricing from drifting too far in either direction, especially on outdoor hard courts where both players have shown enough familiarity to keep the contest close in model terms[1][15].

For traders, the main catalysts were whether the scheduled start held and whether the match reached completion, since this market would have flipped to 50-50 only if the match was cancelled, ended in a tie, or was delayed beyond seven days without a winner[2]. Live schedule listings showed the contest on Court 10 with a planned start around 14:00 UTC, while other Cincinnati matches were stacked around the same session, so any court backlog or weather interruption would have mattered for settlement timing[3][4].

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 Prediction Today, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

UK Frequently Asked Questions

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.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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%.
