Lincoln: Rio Noguchi vs Charles Broom

Platform comparison

Market context

Rio Noguchi and Charles Broom are scheduled to compete in a professional tennis match at the Lincoln event on 13 July 2026, with the settlement window closing on 20 July. The market currently reflects 100% implied probability for resolution, suggesting traders expect the match to proceed as scheduled without cancellation, retirement, or extended delay beyond the seven-day buffer built into the resolution criteria.

The 100% reading warrants scrutiny against historical precedent for lower-tier professional tennis fixtures. ATP Challenger and ITF events—the likely tier for a Lincoln-based tournament—experience cancellation rates between 2–5% and retirement rates of 3–8% depending on draw size and player ranking. Matches that begin but don't finish due to injury or illness typically favour the player leading at the time of withdrawal, triggering a straightforward resolution rather than the 50-50 tie clause. The current probability assumes both players will be fit, available, and willing to compete through completion, a baseline assumption that holds unless injury reports or withdrawal announcements surface.

Traders monitoring this match programmatically should track entry lists and player injury updates through the ATP website and player social media channels through early July. Weather forecasts for the Lincoln venue become material in the final 48 hours; outdoor hard courts are susceptible to rain delays that could push play beyond the seven-day window if the tournament runs behind schedule. Conditional order logic should account for the retirement clause: if Noguchi leads when Broom withdraws, the market resolves to Noguchi, not 50-50, so position sizing should reflect that asymmetry rather than treating all non-completion scenarios identically.

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

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Kalshi Fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

Do I need to KYC for this market?

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