Analysis

This 50% probability reflects market consensus that Pro A (interpreted here as Philadelphia's Eastern Conference championship prospects) has roughly even odds against competing outcomes in the 2026 pro basketball season. The current level balances Philadelphia's apparent market confidence—evidenced by the highest contract price at 13 cents—against uncertainty from other strong contenders like San Antonio (23 cents for Finals), Los Angeles (3 cents), Detroit (3 cents), and New York (7 cents). The probability could shift materially based on trading-deadline acquisitions, injury developments among key players, regular-season performance metrics, or playoff seeding announcements. The 2026 NBA Finals (the ultimate resolution event) will determine the final outcome, making regular-season standings and playoff structure the critical near-term catalysts. High 24-hour trading volumes ($746k–$866k per contract) indicate active repricing as new information emerges.

  • Philadelphia's Eastern Conference contract trades at 13 cents versus San Antonio at 23 cents for Finals win, suggesting market differentiation between conference and championship-level outcomes
  • Total contract volume across top five markets ($3.7M in 24h) demonstrates concentrated trading interest, indicating sensitivity to roster changes and performance data
  • San Antonio's elevated Finals price (23 cents) relative to other teams suggests a specific narrative—likely age of core players, roster composition, or playoff history—that could shift with injuries or trades
  • The gap between Philadelphia's conference price (13 cents) and Finals price (lower) implies markets are pricing in increasing difficulty through subsequent playoff rounds
  • Kalshi contract specificity (named-team outcomes) allows precise pricing but creates potential for market fragmentation if teams trade deadline acquisitions materially change perceived strength

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.
