MLB: Triples Leader

Platform comparison

Active sub-markets

Market context

The latest move is that **Corbin Carroll** remains the clear market leader at **71%**, with the next nearest names far behind, which keeps the trade anchored around one high-variance player rather than a broad field[1]. That matters because triples markets are unusually sensitive to speed, park dimensions and batted-ball luck: a player can post a strong season without ever getting close to the top if the balls in play do not fall in the right spots.

Historically, this type of market tends to be more concentrated than power or RBI races because triples are scarce and often cluster around a small group of fast, extra-base-heavy hitters. Current public stat boards also show Carroll at the top of 2026 triples leaderboards, with other contenders such as Xavier Edwards, Leody Taveras and Pete Crow-Armstrong in the mix, but not yet separated by a large gap in raw totals[2][9]. Pre-season projection models likewise put Carroll ahead of the pack, with FantasyPros projecting him for double-digit triples and the nearest alternatives notably lower[4].

For now, traders should watch three things: whether Carroll keeps his starting role and daily plate appearances, whether any contender gets a playing-time boost through injuries or lineup reshuffles, and whether the National League schedule gives any rivals more opportunities in speed-friendly parks. The official MLB stat pages remain the settlement reference point for season-long leaderboards, while market venues such as Kalshi note that outcomes are verified against league and ESPN data sources[5][6]. The key catalyst is not a single game, but whether the current frontrunner stays healthy and active enough to turn this early lead into a season-ending finish.
