52k contracts traded · 15k open
Real-money positioning across two cycles. Ranked by where the volume actually is — 2028 presidential candidate ladder first (highest dollar volume on Kalshi), then 2026 House control (the closest binary), then the 2028 Senate field (33 states), governor races, and the next-Speaker contender ladder. All Kalshi, CFTC-regulated.
By far the highest-volume political market on Kalshi today. Each row is a candidate-specific YES contract — price is the implied probability that candidate wins the 2028 presidential election. Long-tail names (single-digit prices) are where the operator alpha lives — every 1¢ move on a 6¢ contender is a 16% relative repricing.

Multi-binary contender ladder. The market fairly heavily favors a single name, but the long-tail prices are where the operator alpha lives — every 1¢ move on a 14¢ contender is a 7% relative repricing.

Kalshi’s House-control market prices this in real time — the board above shows the current implied probability for each party. Control comes down to a handful of toss-up districts, so the number moves with generic-ballot polling and candidate recruitment; read today’s price off the live board rather than a static poll.
Each contract is a binary YES/NO on a specific outcome — for example “Republicans control the House after the 2026 election” — that settles at $1 if it happens and $0 if it doesn’t. Kalshi resolves them from the certified election result, so the live price is the market-implied probability of that outcome.
Next-Speaker markets are candidate-specific contracts on who will hold the Speaker’s gavel in the next Congress. Because the Speaker is elected by the majority caucus, they track both which party wins the House and the internal leadership fight — the contender ladder above lists each named candidate’s live price.
In 2024, prediction markets tracked the balance of power closely — the eventual Senate flip was priced from coin-flip to favorite well before most forecasters moved. Our full race-by-race audit is in the 2024 accuracy breakdown linked below.
Kalshi is a CFTC-regulated exchange open to traders in all 50 states, so you can take a position on congressional-control and Speaker contracts directly — no sportsbook, just a contract that settles at $1 or $0. Every row above links straight to its live market.
