Pronóstico: Swedish Open: Jesper de Jong vs Vilius Gaubas

Platform comparison

Market context

The Swedish Open, held annually in Båstad, features Jesper de Jong and Vilius Gaubas in a first-round matchup scheduled for 13 July 2026. The Polymarket contract currently prices de Jong's advancement at 100% (USDC on Polygon), reflecting either overwhelming confidence in the Dutch player or minimal trading volume at settlement. The conditional token structure means traders holding YES shares receive full payout only if de Jong wins outright; any cancellation, retirement mid-match, or delay beyond seven days from the original date triggers a 50-50 split regardless of match status.

De Jong, ranked around 250–280 on the ATP tour, has competed sporadically on the Challenger circuit with mixed results on grass courts. Gaubas, a Lithuanian player with similar ranking proximity, lacks significant grass-court pedigree. Historical precedent suggests first-round upsets at Swedish Open occur at roughly 15–20% frequency, though both players' limited profiles make direct comparison difficult. The 100% probability likely reflects de Jong's marginally higher ranking or recent form rather than genuine certainty.

Traders should monitor official Swedish Open draw confirmations and player withdrawal announcements through ATP Tour channels, typically released 48–72 hours before competition begins. Weather disruptions in Båstad during mid-July occasionally delay matches; the seven-day buffer in the resolution criteria creates meaningful ambiguity if rain forces rescheduling. Any last-minute injury reports or player withdrawals would trigger immediate repricing, though current illiquidity suggests limited arbitrage opportunity.

FAQ

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

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.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Qué Es trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
