Heads-up — heterogeneous clusters

The top two clusters share only 18% of their title tokens — “Will Duke be the #” vs “Will Arizona be the #1 ranked team on Men's College Basketball AP Poll Week”. The headline aggregate weights both, so the number on this page is meaningful only if the clusters resolve to the same question.

Analysis

This probability reflects the chance Duke enters the 2026-27 college basketball season ranked first in the AP Poll's Week 1 preseason rankings. At 20%, markets suggest Duke is considered competitive but not favored for the top spot. The current assessment balances Duke's program strength and recent recruiting against uncertainty about roster construction and how voters will weight returning talent versus incoming players across all top programs. The Week 1 AP Poll, typically released in late October or early November before the season begins, will definitively resolve this outcome. Voter preferences for different programs and their interpretation of summer transfer portal activity will substantially influence where Duke lands relative to other blue-blood programs like Florida and Illinois, which show contract prices between 21-27 cents.

  • Duke's roster composition for 2026-27, including any significant portal departures or high-impact transfers
  • Comparative strength of returning rosters at traditional blue bloods and other programs that might compete for #1 ranking
  • AP Poll voters' preseason preferences and historical biases toward certain programs or coaching tenures
  • Performance and roster decisions by competitor programs like Florida, Illinois, and other traditional powerhouses
  • Official release date and methodology of the Week 1 AP Poll, typically determined in early fall 2026

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.
