Roland Garros WTA: Elina Svitolina vs Marta Kostyuk

Platform comparison

Market context

Svitolina and Kostyuk are scheduled to meet in the Roland Garros women's draw on 2 June 2026. The 65% implied probability favours Svitolina, reflecting her higher career ranking and Grand Slam pedigree. Both players are Ukrainian nationals, adding a layer of familiarity to their matchup. Kostyuk has improved markedly on clay in recent seasons, though Svitolina remains the more decorated performer on the surface, having reached Roland Garros quarter-finals multiple times.

Historical precedent suggests the market's current lean toward Svitolina aligns with conventional seeding expectations at majors. When two players of disparate ranking meet at Roland Garros, the higher-ranked competitor typically settles between 60–70% implied probability unless recent form or head-to-head records suggest otherwise. Svitolina's experience in deep Grand Slam runs and Kostyuk's relative youth in elite competition support this baseline positioning.

Traders should monitor draw announcements and seeding confirmation closer to the event, as these directly influence book depth and liquidity. Injury reports in the weeks preceding the tournament will be critical; either player's withdrawal would trigger the 50-50 resolution clause. Court assignment and scheduling changes—particularly any delays beyond seven days—carry settlement risk. Deposit and withdrawal friction on the platform will affect position sizing; traders relying on SEPA transfers or Klarna on-ramps should account for settlement timelines when managing exposure through the 9 June resolution window.

FAQ

How does Klarna deposit work on PolyGram?

You enter the deposit amount in EUR/GBP, choose Klarna as the method, run through Klarna's standard authentication (Pay Later or Direct Bank Transfer), and PolyGram converts internally to USDC for the Polymarket order book. Processing: typically under 30 minutes.

What does SOFORT cost as a deposit method?

PolyGram 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.

How fast is SEPA deposit?

SEPA Instant: under 10 seconds. SEPA Standard: 1-2 business days. Both accepted fee-free; the internal USDC conversion runs automatically once EUR lands in the platform account.

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.

Are payment details protected?

Yes. Card and bank details are never stored by PolyGram — they pass directly through PCI-DSS compliant payment service providers (Adyen, Stripe). PolyGram retains only transaction IDs and Klarna reference numbers for reconciliation.
