Market context
Henrique Rocha is due to face Borna Gojo in Roland Garros qualifying, with the market settling on who actually advances rather than the nominal start time. Live listings showed the fixture as upcoming on Court 8, while sportsbook prices had Rocha shorter than Gojo, implying a modest edge but not a foregone conclusion. For settlement purposes, the key point is whether the match is completed within the 7-day window and a winner is confirmed; if it is not played, is abandoned, or drifts past the deadline without an advance, the contract falls to 50-50.
The 100% crowd-implied probability is consistent with a market that is already treating the event as effectively decided, but comparable tennis settlement markets often reset quickly when scheduling changes, walkovers, or weather interruptions appear. Gojo’s result page has already been updated by some outlets to show a completed three-set outcome, which, if confirmed on the official draw, would mean the advance is no longer contingent on live play. In these contracts, the on-chain outcome is driven by the official advance condition, so late information from the tournament, ATP feeds, or score providers matters more than in-play sentiment.
The main catalysts are whether Roland Garros qualifying publishes an official completed result, whether any correction appears in the draw sheet, and whether a walkover or retirement is recorded before the settlement window closes. For crypto traders, the broader backdrop is that these event contracts settle in USDC, so any move in BTC or ETH is only relevant insofar as it affects exchange activity, collateral demand, or funding conditions around the market. If the result is firmed up by tournament or ATP reporting before the deadline, the market should settle off that status rather than off live-score ambiguity.
Methodology
Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — are listed with their platform attributes, because they operate off-chain and a 1:1 comparison of contract mechanics isn't possible.
Resolution & payout
Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.
Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.
FAQ

- PolyGram is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.
- 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.
- 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.

- Not under $1,500 of lifetime trading volume. Above that threshold, PolyGram triggers a quick verification flow that finishes in minutes.
