Mayor Zohran Mamdani’s proposed 2-percentage-point surcharge on New York City incomes above $1 million requires explicit authorization from the state Legislature and Governor Kathy Hochul, authority the city lacks under current law. Hochul has repeatedly signaled opposition to broad personal-income tax increases on high earners, citing risks of resident out-migration, and the Legislature has advanced only smaller or alternative revenue measures such as the pied-à-terre tax enacted earlier in 2026. With the 2026 legislative session largely concluded and no bill advancing the full surcharge, the narrow remaining window before the market’s December 31, 2026 resolution date makes passage improbable. Traders assign a 95.6 percent probability to “No,” reflecting these institutional and timing constraints. A late special session, reversal by Hochul, or surprise floor action could still alter the outcome, though such steps lack visible momentum.

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”.
