Bloomfield Hills: Jacob Fearnley vs Tristan Boyer

Platform comparison

Market context

Jacob Fearnley against Tristan Boyer is priced as a heavy Fearnley spot, with the market implying about **94%** for a Fearnley advance. That sits well above the kind of pre-match estimates found in public betting previews, which generally put Fearnley closer to the **mid-60s to high-60s** on straight match odds, with several outlets making him a clear favourite but not close to an overwhelming one.[1][2][3][4]

The historical frame is mixed rather than one-way: Fearnley has been the more consistently backed player in this pairing, and the available preview data from both 2025 and this event leans his way, but the gap between the market’s 94% and the published odds models is large enough to leave room for a contrarian Boyer case if the number is simply overstated.[1][2][3][4] In handicapper terms, consensus is firmly on **Fearnley**, while the value question is whether **Boyer** has been priced too long for a live underdog angle, especially if the match turns into a longer, serve-heavy contest rather than a routine straight-sets win.[3][4]

For traders, the key catalysts are straightforward: whether the match is actually started on schedule, whether either player is withdrawn, and whether tournament scheduling in Bloomfield Hills shifts the pairing beyond the settlement window. Public previews indicate the match was due on 23 July 2026, with Fearnley listed around 1.40–1.45 and Boyer around 2.61–3.25 in the wider betting market, so any late order-of-play change, retirement news or walkover would matter more to the market than incremental form chatter.[1][4][6]

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.
