Prediction Markets MLB Data: Hoerner Stolen Bases, Tatis Runs, De La Cruz MVP Odds Analyzed
Prediction market data reveals sharp-money probabilities on MLB stat titles and award races. We break down the implied odds on Nico Hoerner, Fernando Tatis Jr., Elly De La Cruz, and Owen Caissie.
Prediction markets are generating millions of dollars in trading volume around MLB player-level outcomes this summer. Platforms including Polymarket are seeing active markets on stat titles, award races, and player milestones — with 24-hour volume figures revealing where the sharpest money is paying attention. Here is a data-driven breakdown of the top sports markets and what the implied probabilities tell us about the 2026 season.
Nico Hoerner Stolen Base Market: Volume vs. Probability
The single highest-volume market in the sports category right now is a yes/no proposition on Nico Hoerner leading MLB in stolen bases. The market has generated over $640,000 in 24-hour volume despite pricing the “Yes” outcome at just 0.20 cents — an implied probability of roughly 0.2 percent.
The numbers support the skepticism. Through approximately 73 games, Hoerner has recorded 10 steals for the Chicago Cubs. He stole 43 bases in 2023 to rank fourth in the NL, but his pace has slowed over the last two seasons — 31 in 2024 and 29 in 2025. Bobby Witt Jr. has been setting the pace in 2026, and the gap between Hoerner and the current leaders is significant. The high volume on a near-certain-No market suggests a combination of speculative “lottery ticket” buyers and market makers collecting the spread. From an expected value perspective, the only edge is on the No side, which is already priced near par at $0.998. Check out the full breakdown of how these platforms work at our Polymarket Review.
Fernando Tatis Jr. Runs Title: Context Behind the 0.65% Implied Probability
The market on Fernando Tatis Jr. leading MLB in runs scored carries more analytical meat. The market has traded over $372,000 in 24-hour volume, pricing a Tatis runs-title at 0.65 cents implied — roughly 0.65 percent probability.
Tatis has scored 35 runs in approximately 78 games, producing a run-scoring rate of about 0.45 runs per game. The current MLB runs leader, James Wood of Washington, has posted roughly 0.84 runs per game over the same span. For Tatis to catch Wood, he would need Wood to slow considerably while Tatis accelerates — a double-regression scenario that markets are right to price as unlikely. That said, Tatis led the NL with his 111-run campaign in 2025 and has the tools — .285 average, 19 stolen bases, plus power from the middle of the San Diego lineup — to make a run. Savant data shows his exit velocity and barrel rates are consistent with prior elite seasons.

Elly De La Cruz NL MVP: The 0.3% Market and What It Misses
The market on Elly De La Cruz winning the 2026 NL MVP trades at approximately 0.3 percent implied probability, with over $274,000 in 24-hour volume. That pricing reflects the brutal reality of the MVP ballot competition — Shohei Ohtani, Yordan Alvarez, and other two-way or elite offensive contributors typically dominate voting cycles.
De La Cruz’s underlying performance, however, is legitimately MVP-caliber in isolation. He is hitting .273 with 12 home runs, 38 RBI, and 10 stolen bases through 59 games. His 2026 first-half pace projects to roughly 33 home runs and 28 stolen bases over a full season — a combination virtually no player in the modern era has sustained at that level while also playing premium shortstop defense. His +9 defensive fielding run value in 2024 validated that he can be an elite glove when healthy. The market is not wrong to discount him heavily, but the 0.3 percent price implies virtually zero path to the award even if he runs a 30-30 season and the Reds contend. Worth monitoring as a potential live trade if the Reds get back to .500. Our Kalshi Promo Code page has the latest welcome offer for those looking to trade these markets directly.
Owen Caissie NL Rookie of the Year: Early Edge Has Faded
Owen Caissie opened the season as a Rookie of the Year favorite in several markets after his walk-off homer on Opening Day. The Miami Marlins outfielder produced a scorching early pace — hitting .350 with a .991 OPS through his first 12 games. But the market on Caissie winning the NL ROTY now prices “Yes” at under 0.5 percent on $407,000 in volume, reflecting a return to earth in his numbers.
Through approximately 65 games, Caissie is hitting .221 with 10 home runs and 47 RBI. His strikeout rate is high — 87 in the NL through mid-June — which tends to be a differentiator when the BBWAA writers deliberate. His power is real, however, and if his contact rate improves in the second half, he could emerge as a legitimate candidate. The NL Rookie field is competitive this season and markets appear to be pricing a consensus view rather than a single leader. For bettors who want a traditional prop wager instead of a prediction market position, major sportsbooks are offering ROTY props with better early odds than you will find in the liquid market right now.

Reading the Volume Signals
High-volume prediction markets on seemingly lopsided outcomes are a consistent feature of prediction market ecosystems. The Hoerner stolen base market is the clearest example — $640,000 in 24-hour volume on a near-certain outcome suggests the market’s value is in engagement and speculative activity rather than genuine price discovery.
The more analytically interesting data comes from the implied probabilities themselves, which function as a real-time crowd forecast with financial stakes attached. The 0.65 percent price on Tatis for the runs title is the kind of market that merits a second look as the season progresses, particularly if the NL West landscape shifts and Tatis gets into a sustained hot streak. Traders who understand how to convert implied probability to expected value have a natural edge in markets where the volume is high but the analysis is shallow.
