Analysis

Markets are pricing a 59% probability that New York City's Department of Housing Preservation and Development (HPD) will report more than 30,000 affordable housing unit starts during fiscal year 2027 (July 2026–June 2027) in the annual Mayor's Management Report. The distribution of contract prices—ranging from 92% probability above 15,000 units down to 46% above 35,000 units—suggests traders expect outcomes concentrated in the 15,000–25,000 range. HPD's actual production capacity, funding availability from city and state budgets, and permitting timelines are the primary factors shaping expectations. The outcome will be definitively resolved when HPD publishes its official Mayor's Management Report in summer 2027, which reports the prior fiscal year's housing starts. Historical performance data and current project pipelines suggest most traders view 30,000 starts as an ambitious but achievable target.

  • HPD's historical annual affordable housing starts (2020–2025) provide a baseline for assessing whether 30,000 units represents continuation, acceleration, or a departure from recent trends
  • Current city and state capital budgets committed to HPD housing development programs as of mid-2026 determine available funding to initiate new projects during the fiscal year
  • The volume of projects that received final permits and were ready to break ground by July 2026 directly constrains starts possible during the July 2026–June 2027 period
  • NYC's construction labor market conditions and material costs in late 2026 affect whether developers can actually mobilize workforce and equipment to begin projects
  • The Mayor's Management Report definition of 'housing starts' (likely tied to DHCR filings or formal construction commencement) determines the exact counting methodology used to calculate the final reported number

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.
