Bloomfield Hills: Jacob Fearnley vs Tristan Boyer

Platform comparison

Market context

Polymarket is pricing this **Fearnley v Boyer** contract at **87% YES** on the conditional token set, with settlement in **USDC on Polygon** if the official match outcome is clear before the window closes. That level implies the market is heavily leaning towards the contract resolving to **Jacob Fearnley**, rather than the fallback **50-50** outcome that would apply if the match were not played, ended level, or slipped more than seven days beyond the scheduled date.

The main historical anchor is the pair’s direct record: TennisExplorer lists the head-to-head at **1-0** to Fearnley[1]. In a short-format tennis market like this, traders usually weight a clean prior meeting more than broader ranking noise, because one confirmed result can be a better guide to how the matchup has traded than season-long form alone. That said, a single head-to-head is thin evidence, so an 87% price still leaves room for the market to be wrong if recent conditions, surface fit, or fitness have shifted since that meeting.

For a Polymarket user, the practical catalysts are straightforward: keep an eye on whether the Bloomfield Hills schedule stays intact, whether either player withdraws before first serve, and whether an official result is posted quickly enough for the contract’s settlement rules. Because the market resolves on a binary advance/no-advance basis, late cancellations or an abandoned match can matter more than pre-match sentiment. The key question for traders is not just who is favoured, but whether the event is actually completed in a form that triggers a normal resolution rather than the 50-50 fallback.

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.
