MLB: Triples Leader

Platform comparison

Active sub-markets

Market context

The 2026 MLB regular season triples race is currently led by Corbin Carroll, with the market pricing him at 71% and FOX Sports showing him level on 11 triples with Luis Arraez, while Xavier Edwards and Pete Crow-Armstrong sit just behind on 10. That concentration at the top matters because triples are a low-count category: a single week of contact quality, outfield spacing, or leg injuries can swing the leader board quickly, so the current price reflects a strong but not lock-tight position rather than a settled outcome.[1][2]

Historically, triples markets tend to trade on exposure to speed, ballpark geometry, and batted-ball volatility more than on raw power. Carroll’s profile has been the cleanest fit for this category so far, but the gap is still small enough that a hot stretch from a trailing runner, or a brief injury absence, can compress the edge fast. For traders, the practical relevance is that this kind of book depth is often fed by small, fast deposits rather than large balances; lower-friction funding rails such as Klarna, SEPA, or USDC can matter because they decide how quickly liquidity can respond when the leaderboard shifts.[1][2]

The catalysts to watch are the official MLB statistical updates, daily box scores, and any public injury or rest news affecting the front-runners, especially Carroll, Edwards, and Crow-Armstrong, as their triple totals can move on a single extra-base hit. Because the market resolves to the official leader at season end, with MLB tie-break rules applying if needed, late-season games and any announcement about statistical verification are the key dependency, not current month-to-month sentiment. As of the latest public market page, Polymarket’s own pricing still has Carroll clearly ahead, but the trailing names remain close enough that schedule strength and availability through September could alter the final settlement profile.[2][5]

Methodology

We track MLB: Triples Leader on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
