Market context
Polymarket is pricing this Segovia qualifier at **0% YES**, so on the market’s own terms the contract is trading as if Florent Bax is extremely unlikely to advance against Paul Inchauspe. On Polymarket, the position is settled in **USDC** through **Polygon**-based conditional tokens, with the binary outcome turning on whether Bax advances, or whether the event falls into the market’s 50-50 fallback if the match is not played or is otherwise unresolved within the rules.
For comparison, independent match previews ahead of the scheduled meeting had Paul Inchauspe as the narrow market-side favourite, with Tennis Tonic’s pick also leaning Inchauspe in three sets and listing him at 1.63 versus Bax at 2.11. That kind of pre-match edge helps explain why a Bax YES contract can sit near zero when traders see little separation between the players but still assign the other side the clear advantage.[1]
The main catalysts are procedural rather than speculative: whether the match is actually played, whether it starts and reaches a completed result, and whether any official postponement pushes resolution into the market’s 7-day tie bucket. Traders should watch the Segovia order of play, tournament communications, and any late withdrawal or rescheduling notice, because those determine whether the contract resolves to Bax, Inchauspe, or the 50-50 fallback regardless of the on-court favourite.[1]

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
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- 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.
- 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.
- 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.
