Market context

The National League's Comeback Player of the Year award recognises a player who returns to competitive form after injury, illness, or significant time away from play. The 2026 award will be voted on by a panel of baseball writers and broadcasters following the regular season, with the winner typically announced in November. At 13% implied probability, the market reflects uncertainty about which players will qualify and perform well enough to merit the honour.

Historical precedent shows the award favours players with measurable statistical recovery rather than marginal improvements. Recent winners including Luis Severino (2022) and Bryce Harper (2019) had undergone extended absences—surgery, injury rehabilitation—before posting All-Star calibre seasons. The voting pool typically narrows to three to five genuine contenders by season's end, meaning early-season performance trajectories and injury reports from spring training will substantially narrow the field. Players returning from Tommy John surgery, major joint reconstruction, or season-ending injuries sustained in 2024 or early 2025 will dominate consideration.

Traders should monitor spring training reports beginning February 2026, particularly for players cleared to return from significant procedures. MLB's injury database and team announcements regarding rehabilitation timelines will signal which players are genuinely in contention. The voting announcement schedule—typically mid-November 2026—creates a hard deadline for performance data. Any unexpected mid-season injuries to leading candidates or surprise breakout seasons from previously overlooked returning players could shift the probability substantially in the final weeks before the award is decided.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
