Swiss Open: Kilian Feldbausch vs Miomir Kecmanovic

Platform comparison

Market context

The Swiss Open match between Kilian Feldbausch and Miomir Kecmanovic in Gstaad is set to begin today, with the crowd-implied probability favouring Kecmanovic at 70% against Feldbausch’s 30% YES. On Polymarket, this contract trades in USDC on the Polygon network, where conditional tokens reflect the market’s assessment of Feldbausch advancing. The discrepancy between the 30% market price and external models projecting a 72–73% win probability for Kecmanovic suggests a potential mispricing opportunity for traders monitoring the on-chain liquidity.

Historical precedents in ATP Gstaad show that lower-ranked players like Feldbausch occasionally disrupt higher-ranked opponents, but Kecmanovic’s recent form and head-to-head advantage make such an upset statistically rare. Similar mismatches in Swiss Open history typically resolve within the expected probability bands, with the market correcting quickly once live odds shift. The current 30% price for Feldbausch appears conservative compared to simulation data, which consistently projects Kecmanovic as the clear winner.

Traders should watch for pre-match announcements regarding player fitness, as injury withdrawals or walkovers would trigger a fair-price resolution per the market rules. The match schedule is fixed for 04:40 local time, but any delay beyond seven days without a winner results in a 50-50 settlement. Recent coverage from Dimers highlights Kecmanovic’s dominance in simulations, reinforcing the view that the current price may understate his likelihood of advancing [1]. Monitor the ATP Gstaad draw updates and live score feeds for real-time catalysts that could shift the conditional token value before settlement.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.

FAQ

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'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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi UK 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.
