3 prediction markets price this story:
- Before 2027 — resolved “Yes” on 30 Sept 2026. The outcome is Yes if a New York State court grants preliminary or permanent injunctive or annulment relief against the city's pied-à-terre surcharge in O'Brien v. City of New York before January 1, 2027. The outcome is No if such relief is not granted within that timeframe.
- Yes — the market puts it at 12%, closing 1 Jan 2027. The market resolves to Yes if New York City passes legislation that increases its property tax rate before January 1, 2027. Otherwise, it resolves to No. Readers often mistake the linked court order for the required legislative action.
- Before 2027 — the market puts it at 9%, closing 1 Jan 2027. The outcome is Yes if a law raising the NYC Business or New York State corporate tax rate becomes law before January 1, 2027. Otherwise, the outcome is No. Readers often mistake the linked court order for the tax change itself.
