Tampere: Gauthier Onclin vs Tom Gentzsch

Platform comparison

Market context

Gauthier Onclin’s meeting with Tom Gentzsch in Tampere is effectively priced as a done deal on Polymarket, with the contract at **100% YES** for Onclin. In practical terms, that means the market is treating Onclin as the near-certain advancement outcome, with settlement driven by the actual match result rather than the pre-match narrative. On Polymarket, positions are held as **USDC** on **Polygon** through conditional tokens, so the only thing that ultimately matters is whether the event resolves to Onclin, Gentzsch, or a fallback 50-50 outcome if the match is not played or is delayed beyond the market’s rules.

That certainty sits well above the more conventional pricing seen elsewhere. Tennis.com lists Onclin vs Gentzsch as a quarter-final with a projected winner probability of **52%** for Onclin, while Tennis Tonic also leans Onclin, but only narrowly, noting opening odds of **1.78** for Onclin and **1.9** for Gentzsch, and calling for an Onclin win in three sets.[1][2] In other words, the broader tennis market still reads this as a competitive matchup, so a 100% Polymarket price suggests either extremely late information, thin liquidity, or a contract that has effectively already absorbed a near-certain advancement outcome.

For traders, the key catalysts are not abstract form lines but the operational details: whether the match stays on schedule, whether either player withdraws, and whether any postponement pushes the result beyond the 7-day settlement window that would trigger the 50-50 fallback. Fanatics Markets’ standard wording is similar in spirit, resolving on the match winner and handling cancellation separately, which underlines how sensitive these contracts are to tournament administration rather than just on-court play.[3] With a current crowd price already pinned at 100%, any late draw change, medical timeout leading to retirement, or schedule shift is the main thing that could still move the settlement outcome.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.

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 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?

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.
