Governor Kathy Hochul’s consistent opposition to new income tax increases on high earners, combined with the need for state legislative approval in Albany, has anchored trader expectations that the proposed 2% surcharge on New York City incomes above $1 million will not become law by December 31, 2026. Mamdani secured a pied-à-terre tax on luxury second homes through the 2026 budget process as a narrower revenue measure, but broader personal income tax changes face entrenched procedural and political hurdles in the remaining months of the session. With the next regular legislative window opening only in January 2027 and Hochul prioritizing other fiscal tools, the compressed timeline and institutional requirements explain the 96.9% implied probability on “No.” Late-session budget negotiations or shifts in gubernatorial priorities represent the primary, though narrow, paths that could still alter the outcome.

Zohran Mamdani has proposed adding a flat 2% tax on New York City residents earning above $1,000,000 annually. You can read more about that here: https://drive.google.com/file/d/14-aM9DKG337SDMilmfQtLRR-pDwyWSTc/view
This market will resolve to “Yes” if both the following occur:
1. Zohran Mamdani wins the 2025 NYC Mayoral election.
2. A policy is enacted in New York City before December 31, 2026, 11:59 PM ET, which would establish a tax increase of 2% or more targeting individuals, households, or family units with an income of at least $1 million (USD or equivalent).
When the proposed tax goes into effect (e.g., if a qualifying tax is enacted for the 2028 fiscal year) will have no bearing on this market's resolution, so long as the policy has actually been enacted within this market's timeframe.
The policy will be considered to have been enacted if a local or state law is passed, or mayoral executive order is issued which will bring the stated tax into effect within the specified timeframe. The introduction, proposal, or announcement of such a policy without legal enactment will not qualify.
Policies which include limited exceptions—such as such as exceptions for specific families, asset classes, etc.—will still qualify as long as a general tax as described is enacted.
If Mamdani is confirmed to have lost the 2025 NYC Mayoral election by a consensus of credible reporting, or if the stated terms are not satisfied within this market's timeframe, this market will immediately resolve to “No”.
