New Hampshire Senate: Chris Pappas at 90% on Kalshi and 89% on Polymarket

Chris Pappas stood at 90% on Kalshi and 89% on Polymarket in the New Hampshire Senate snapshot published Oct 15, 2026, at 1:39 PM ET. The two platforms were separated by one percentage point, with both pricing him as the strong favorite.

The snapshot followed a quiet 15-minute stretch with no significant new platform headline, according to the accompanying summary. It provides a cross-platform comparison, rather than evidence of a fresh move in either market.

The wider Senate picture

According to defirate.com, Senate debates in Maine, Georgia and Iowa on October 13, alongside a new Marist poll placing Texas within two points, framed the opening of the final three weeks. Its tracker compares live prices for all 35 U.S. Senate elections in 2026 across Kalshi, Polymarket, Polymarket US, Gemini and OG, while examining the races’ implications for Senate control.

The supplied defirate.com excerpt also displays a GOP buy price of 44¢ and states that $100 placed at the ask would pay $227 if correct, before fees. The excerpt does not identify the precise contract attached to that quote, so it cannot be treated as a New Hampshire price or directly compared with the Pappas snapshot.

What it means for prediction markets

• Broad agreement, not certainty: Pappas’s 90% Kalshi and 89% Polymarket readings show closely aligned expectations, but neither price guarantees the outcome.
• No established trend: Without earlier prices or trading-volume data, the snapshot does not establish whether confidence in Pappas is rising or falling.
• Contract context matters: The separate GOP 44¢ quote lacks enough identifying detail to support a comparison with the New Hampshire race.
