Bloomfield Hills: Jacob Fearnley vs Tristan Boyer

Platform comparison

Market context

Polymarket is pricing the **Jacob Fearnley** side at about **94%**, which is far above the kind of pre-match edge seen in bookmaker markets and model-based tennis previews. That gap matters because the contract settles on whether Fearnley advances against Tristan Boyer, with the payout handled through Polymarket’s **USDC**-denominated, **Polygon**-based conditional token structure rather than the scoreline itself. If the match is played and produces a winner, the market resolves on who advances; if it is not played, or is delayed beyond seven days without a winner, it falls to **50-50** under the market rules.

Comparable pre-match sources point the same way, though not nearly as strongly: Oddspedia lists Fearnley as the favourite at around **1.4** decimal odds, Tennis Tonic also leans to Fearnley, and Matchstat’s moneyline-derived estimate puts him at roughly **64.29%**.[1][2][3] That makes the current crowd price look much firmer than the broader tennis pricing landscape, which usually reflects a mix of player form, surface, and late scheduling risk rather than certainty. For a Polymarket trader, the key read is not just “Fearnley is favoured”, but that the contract already assumes a very high probability of him advancing.

The main catalysts are straightforward: the match must actually start, and it must reach a result before the seven-day fallback window closes. The practical risk is not a sudden change in Fearnley’s underlying strength so much as **schedule disruption**, late withdrawal, retirement, or a delay that pushes settlement into the special 50-50 outcome. With the event originally set for 23 July in Bloomfield Hills, any official draw update, court assignment, or tournament communication becomes relevant only insofar as it confirms the match is still on track to be completed inside the window.

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.
