Lexington: Spencer Johnson vs Andre Ilagan

Platform comparison

Market context

The match is a straight head-to-head in Lexington between **Spencer Johnson** and **Andre Ilagan**, and the market resolves on who advances rather than on full match score. Johnson is the better-documented player in public data: ESPN lists him as a 23-year-old American with no ATP ranking shown, while UCLA’s roster and recent USTA Southern California coverage show he has spent 2025-26 splitting time between college tennis and pro events, including first pro singles and doubles titles in Irvine earlier in 2026.[1][16][17]

A **0% YES** crowd price implies the market is treating Johnson’s path as effectively dismissed, which is usually what happens when one side is presumed not to appear, is not entered, or has already been eliminated by tournament context. For programmatic readers, the useful workflow is to treat this as a status-check market: poll the draw, order of play, and match completion state, then map any withdrawal, walkover, retirement, or delay past the 7-day rule to the 50-50 settlement condition rather than to a player win. Johnson’s recent results also matter because he has been active in Lexington-specific coverage and won his previous Lexington match against Jay Friend, which confirms he was in the event ecosystem around the draw.[4]

The main catalysts are operational rather than statistical: the published schedule, any official ATP/ITF draw update, and late injury or withdrawal notices from the event or player channels. If you are wiring bots or conditional orders, the key trigger is whether the match actually starts; once play begins, a retirement or unfinished match can still settle to an advancing player, whereas a non-played postponement can push the market into the tie bucket if the 7-day window is breached.[4][17]

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.
