Analysis

The 86% probability indicates market participants believe De Paula will play in an MLB game by November 2028, though the much lower prices on earlier dates (6% by May 2027, 7% by August 2027) suggest uncertainty about near-term timing. The probability reflects De Paula's current status in professional baseball development—likely a minor league prospect—and the typical pathway to MLB debut. Key drivers include his progression through the minor league system, organizational depth at his position, and availability of roster spots. The primary uncertainty resolver will be roster decisions during spring training and early-season MLB operations, particularly around roster expansion or injury replacements that might accelerate or delay debut opportunities.

  • The steep discount on near-term contracts (6% for May 2027) versus the long-term outlook (86% by Nov 2028) suggests De Paula has not yet been called to MLB but has reasonable long-term prospect status
  • Minor league development timelines typically span 2-5 years; De Paula would need to progress through multiple levels and outcompete organizational competition for a roster spot
  • Spring training rosters and early-season injury replacements between June 2026 and May 2027 represent the most likely near-term MLB debut catalysts
  • MLB roster composition and organizational needs at De Paula's position will directly influence whether a debut occurs before late 2028 versus later years
  • The minimal trading volume on most contracts suggests limited market liquidity and potential uncertainty about De Paula's current professional status or visibility

How we compute these odds

SimpleFunctions aggregates live prediction-market contracts from Kalshi and Polymarket. Each slug groups contracts that resolve on the same underlying event, identified by venue event_id.

For binary slugs, the headline probability is the liquidity-weighted mid-price across all bound contracts. For multi-outcome slugs (e.g. elections with 3+ candidates), the headline is the leader’s price; we never arithmetically average disjoint outcomes — that would produce a number with no real-world meaning.

Snapshots refresh every 5 minutes during market hours; daily aggregates are computed at 04:00 UTC. The 30-day sparkline is drawn from per-ticker daily means stored in market_indicator_daily; 24h delta and movement events are derived from the same source.
