Analysis
This contract predicts whether Luis Peña will appear in at least one MLB game before May 1, 2029—roughly three years from now. The 3% probability reflects significant uncertainty about Peña's ability to reach or return to active MLB roster status. The main drivers of this low probability are his current status and the competitive barrier to MLB roster spots; factors that could shift this include recovery from injury, successful minor league performance leading to promotion, or unexpected roster circumstances. The most critical near-term catalyst would be any official roster transaction or medical clearance announcing his return to active baseball. No specific scheduled event immediately resolves this, but each team's roster moves and injury updates over the next two seasons will provide evidence.
- ›Luis Peña's current employment status and whether he is actively signed or training with any MLB organization, minor league affiliate, or independent league
- ›His injury history and medical clearance status, which directly constrains his availability for roster consideration
- ›The total pool of available roster spots and competitive depth charts at his position, determining how likely promotion becomes even if performance warrants it
- ›Performance metrics if he plays in minor league or independent settings, which would be observable indicators of readiness for MLB return
- ›Any official transactions, contract signings, or team announcements regarding his status within the next 24-36 months

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.
