Analysis

Markets currently price an 78% likelihood that the Portland Trail Blazers will not relocate or announce relocation before the 2027-28 NBA season begins, with a 22% combined probability of moves to Seattle (8%) or Tampa Bay (4%). This reflects modest but non-trivial uncertainty about the franchise's future location. The high probability of staying suggests traders believe current ownership and local stakeholders have sufficient incentive to keep the team in Portland, though the franchise's competitive performance and arena infrastructure could drive changes. NBA relocation discussions typically accelerate during ownership transitions or when market conditions shift significantly. Key resolution events include any public statements by current ownership, potential ownership sales, arena renovation announcements or denials, and the franchise's on-court performance trajectory through the 2026-27 season.

  • ›Trail Blazers' current ownership structure and stated commitment to Portland operations
  • ›Availability and viability of competitive NBA markets (Seattle arena readiness, Tampa Bay market size and existing teams)
  • ›Franchise competitiveness and ticket sales trends over the 2025-26 and 2026-27 seasons
  • ›Portland's arena infrastructure plans and local government support for facilities improvements
  • ›Any public statements from NBA leadership, ownership groups, or city officials regarding relocation discussions

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.
