Pennsylvania’s 7th District
Pennsylvania’s 7th, a Lehigh Valley seat Republican Ryan Mackenzie won by inches, prices as a likely Democratic flip — the market has Democrat Bob Brooks ahead. A first-term incumbent who won a squeaker, running in a midterm tilted against his party, is the board’s recurring flip profile. The live contract is the read on whether the Valley snaps back to its Democratic lean.

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 (Pennsylvania’s 7th District) is held by Ryan Mackenzie (Republican); because a real-money market reprices continuously, take today’s favorite off the price, not a static rating.
The general-election candidates for the PA-07 House race are Bob Brooks (Democrat) and Ryan Mackenzie (Republican), per the Kalshi contracts, whose rules name each candidate’s party as of 2026-10-06. Election Day is November 3, 2026.
Kalshi lists the PA-07 House winner as YES/NO contracts, one per party, each settling at $1 if that side wins and $0 if it doesn’t. Buy the side you think is underpriced relative to your own probability, and the difference is your edge. Kalshi is CFTC-regulated and open to traders in all 50 states; every price on this page links straight to the live market.
Prediction markets had a strong 2024 — Kalshi and Polymarket called all seven presidential swing states correctly the night before, often while the polling averages were still split. Our full state-by-state scorecard, including where the markets missed, is in the 2024 accuracy audit linked below, and it’s the best base rate for how much to trust the PA-07 contract this cycle.
