MLB: Stolen Bases Leader

Platform comparison

Active sub-markets

Market context

The market resolves on which player steals the most bases during the 2026 MLB regular season, with Nasim Nuñez currently leading the standings at 31 steals and Bobby Witt Jr. close behind at 28 [1][2]. Historical data shows that early-season leaders often maintain their advantage, yet projections for the full season suggest Elly De La Cruz and Chandler Simpson could surpass current totals with 41 steals each [6]. The crowd-implied 8% probability reflects the volatility of a race where top contenders like Nuñez and Witt Jr. face injury risks and lineup changes that could derail their momentum before September.

Traders should monitor upcoming roster announcements, player health updates, and team scheduling dependencies, as these factors directly influence stolen base opportunities. Recent news from StatMuse confirms Nuñez’s lead but highlights the tight competition, with Witt Jr. and José Ramírez also in contention [1][2]. The market’s traction ties to funding flows driving book depth, where deposit friction via Klarna, SEPA, or USDC rails affects how quickly traders can adjust positions on these catalysts. Withdrawal fees and payment delays further shape participation, making liquidity a key variable in price discovery for this high-stakes outcome.

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.
