New York’s 4th District
New York’s 4th, a Long Island seat Democrat Laura Gillen flipped back, prices as a likely hold — the market has Gillen ahead of Republican Jeanine Driscoll despite the district’s swing reputation. New York’s suburban seats whipsawed hard in recent cycles, so the contract’s confidence is worth stress-testing. The live price tracks whether the 2024 suburban Republican surge is reversing.
Quick Answer
As of August 27, 2026, Laura Gillen leads the NY-04 House market at 90¢ — real money putting the implied probability at 90%. Forecasters rate the seat Likely D, so the gap between that rating and this price is the whole question.

How to read this
Each contract pays $1 at resolution, so the price in cents is the market’s implied probability — a 58¢ contract is a 58% chance. When the leading price sits near 50¢, the market is telling you the district is a genuine coin flip.
The live board above shows the current market favorite — read each contract’s price as the market’s implied probability, so a 55¢ contract is a 55% chance. Going into the cycle the seat (New York’s 4th District) is held by Laura Gillen (Democrat) and rated likely d; because a real-money market reprices continuously, take today’s favorite off the price, not a static rating.
