Market context

Daniil Medvedev’s meeting with Botic van de Zandschulp at the National Bank Open is trading as a low-probability underdog outcome for Medvedev’s opponent, with the market implying roughly a **17%** chance of van de Zandschulp advancing. That sits comfortably below the broader pre-match pricing, where Medvedev is the clear favourite: one current odds feed has him around **-475** on the moneyline, while another preview puts his win odds close to **1.26–1.28**. [7][2][14]

Historical framing points the same way. Medvedev has a strong hard-court profile and, according to a current event page, a **4-0 head-to-head record on hard courts** against van de Zandschulp, with prior meetings ending in straight sets. Comparable market snapshots also show Medvedev priced as a likely winner in round-two previews, while van de Zandschulp has tended to attract only modest support when he enters as a large outsider. [1][10][12]

For traders, the key catalysts are not macro headlines but match-state mechanics: any official postponement, walkover, retirement before completion, or delay beyond seven days can push the market towards the contract’s tie-style settlement path rather than a normal winner result. The listed match page shows the contest as a second-round National Bank Open fixture, so the practical risk is scheduling disruption rather than format ambiguity; in on-chain terms, resolution still flows through USDC settlement once the outcome is finalised, with the market’s price mainly reflecting tennis-specific status updates rather than BTC or ETH direction unless broader crypto risk moves are unusually sharp.

Methodology

This page reads National Bank Open: Daniil Medvedev vs Botic van de Zandschulp on-chain. Polymarket's quote comes directly from the Polygon order book — the only comparable venue with on-chain settlement. Kalshi (USD, off-chain), Betfair (GBP/EUR, off-chain) and Manifold (play-money) are listed alongside for venue context. Every CTA routes to BTC Prediction, which mirrors the Polymarket order book directly.

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

What are crypto prediction markets?
Crypto prediction markets are on-chain smart contracts where you buy YES or NO shares on a future crypto event (e.g. "BTC above $100k by year-end"). The market price between 0¢ and 100¢ is the implied probability.
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%.
