94% — Will Vahn Lackey play in a game for any team in the MLB before Nov 1, 2030 Leader: Before Aug 1, 2030 at 94% · Kalshi 94% · 8 contracts · $175 volume · medium confidence Updated 2026-07-12 23:03:44 UTC Tracks the leading outcome in a winner-take-all prediction market set with 8 outcomes. Why this matters: This market indicates an 93% probability that Vahn Lackey will appear in at least one MLB game before November 1, 2030. The high confidence reflects typical career progression timelines for prospects who reach the MLB pipeline, with most players either debuting or being eliminated from contention within a 4-year window. Market prices suggest increasing uncertainty as the deadline extends further, with the probability declining only slightly from an 87% forecast for May 2030 to 93% by November 2030—indicating some skepticism about whether Lackey will sustain eligibility through the full period. The primary factors driving this probability are Lackey's current status in professional baseball development, injury risk, and performance benchmarks at lower levels that typically precede promotion. Key factors: - Current age, minor league level, and projected timeline to MLB readiness based on organizational depth charts and published prospect rankings - Historical debut rates for pitchers at Lackey's development stage, accounting for injury, performance plateaus, and organizational decisions to promote or decline prospects - Team roster composition and availability of positions entering 2029-2030 season, which determines whether a slot exists for a debut opportunity - Significant injury or performance regression documented in official minor league statistics that would materially reduce promotion probability - Organizational changes, trades, or salary cap pressures that might accelerate or delay prospects entering the active roster Contracts: - Will Vahn Lackey play in a game for any team in the MLB before Aug 1, 2030?: Before Aug 1, 2030 — 94¢ Kalshi $5 (weight 3%) - Will Vahn Lackey play in a game for any team in the MLB before Nov 1, 2030?: Before Nov 1, 2030 — 93¢ Kalshi $6 (weight 3%) - Will Vahn Lackey play in a game for any team in the MLB before Nov 1, 2031?: Before Nov 1, 2031 — 92¢ Kalshi $12 (weight 7%) - Will Vahn Lackey play in a game for any team in the MLB before May 1, 2029?: Before May 1, 2029 — 82¢ Kalshi $72 (weight 41%) - Will Vahn Lackey play in a game for any team in the MLB before May 1, 2030?: Before May 1, 2030 — 82¢ Kalshi $33 (weight 19%) - Will Vahn Lackey play in a game for any team in the MLB before Nov 1, 2029?: Before Nov 1, 2029 — 81¢ Kalshi $33 (weight 19%) - Will Vahn Lackey play in a game for any team in the MLB before Aug 1, 2029?: Before Aug 1, 2029 — 80¢ Kalshi $13 (weight 7%) - Will Vahn Lackey play in a game for any team in the MLB before Nov 1, 2028?: Before Nov 1, 2028 — 44¢ Kalshi $1 (weight 1%) --- ## Methodology SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged.
