## Analysis

This represents the market's assessment that there is a roughly 1-in-4 chance New York will raise its corporate tax rate by early 2028. The relatively low probability reflects structural barriers to such legislation: New York State requires gubernatorial approval, and recent administrations have prioritized business-friendly policies and economic competitiveness. However, the probability rises to 31% by 2029 and 36% by 2030, suggesting markets see increasing pressure for tax increases over time. Key drivers include state budget deficits, calls from progressive legislators for revenue increases, and shifting political dynamics. The most significant near-term catalyst would be the 2026 gubernatorial election results and subsequent budgeting cycles, which typically occur in early 2027 and would establish the administration's fiscal priorities for the remainder of the forecast period.

### Key factors

- Current New York governor's publicly stated position on corporate taxation and track record on tax policy changes
- State budget projections and structural deficits for fiscal years 2027-2028, which typically drive revenue discussions
- Composition of New York State legislature after the 2026 midterm elections and any shifts in progressive caucus strength
- Historical frequency of significant tax rate changes in New York and typical legislative timeline from proposal to passage
- Economic conditions and business climate messaging from major employers and industry groups operating in the state

## Methodology

Probability is **liquidity-weighted** across all bound Kalshi/Polymarket contracts: Σ(price × volume) ÷ Σ(volume). 30-day trajectory uses the daily mean of intraday 5-min captures. 24h delta = today's mean − yesterday's mean. Movement events are ≥3pp daily moves in the last 7 days.
