National Bank Open: Liudmila Samsonova vs Elena Rybakina

Platform comparison

Market context

Elena Rybakina’s meeting with Liudmila Samsonova in the National Bank Open is priced at a modest Samsonova lean, with the market implying roughly a quarter chance of a Samsonova advance. That sits against a head-to-head that has generally favoured Samsonova overall: several databases list her ahead 4-2, with a 4-1 edge on hard courts, although Rybakina won their latest two meetings in 2024 and 2025. [2][8][11]

For context, this is the sort of matchup where payments and on-ramp friction can matter more than the headline probability. A 26% price usually reflects thinner depth than a top-tier final, so flows from users who can deposit quickly via cards, Klarna-style pay-later rails, SEPA transfers, or USDC often move the book more than the underlying number suggests. In practical terms, fast funding and easy withdrawal rails tend to support tighter spreads and faster repricing when the market opens or when lineups firm up.

The main catalysts are straightforward: whether the match starts on schedule, whether either player withdraws, and whether tournament scheduling shifts the pair onto a different court or session. The market settles on the player who advances, but a cancellation or a delay beyond seven days from the scheduled date would push it to 50-50 under the rules. Recent tournament previews also note that this is expected to be their seventh career meeting, which keeps the market tied to a known matchup rather than an unknown draw spot. [8][10][16]

UK Frequently Asked Questions

What does SOFORT cost as a deposit method?

Polymarket Klarna UK charges no fees for SOFORT. The only cost is the internal FX spread (typically <1%) on EUR→USDC conversion. SOFORT itself has no end-user fees — the platform absorbs acquirer costs.

Can I deposit with a credit card?

Yes, Visa and Mastercard. Credit card deposits carry a ~2.5% acquirer surcharge (standard for card payments). Apple Pay and Google Pay run on the same card rails — same surcharge.

Can UK traders use Klarna to deposit on Polymarket?

Polymarket does not natively accept Klarna. To fund a Polymarket account from the UK, you must first purchase USDC via a crypto exchange (Coinbase UK, Kraken) or Revolut, then transfer to a Polygon-compatible wallet. Some third-party on-ramps (MoonPay, Transak) accept UK debit cards and may support Klarna buy-now-pay-later for crypto purchases.

What payment methods can UK users use for Polymarket?

UK traders typically use: (1) Coinbase UK or Kraken — buy USDC with GBP debit card or bank transfer; (2) Revolut — buy crypto and send to wallet; (3) MoonPay or Transak — Visa/Mastercard UK debit card directly to USDC on Polygon. Standard GBP-to-USDC conversion fees range from 0.5–2.5%.

How long do Polymarket withdrawals take for UK users?

Polymarket withdrawals to your Polygon wallet are instant (on-chain). Converting USDC back to GBP via Coinbase UK or Kraken typically takes 1–3 business days for bank transfer, or near-instant for Revolut. Polygon gas fees are minimal (<$0.01 per transaction).
