Kalshi’s 2026 Midterm Trading Tops $2.5 Billion Across Races

By Daniel Okafor

Kalshi said trading in prediction-market contracts tied to the 2026 U.S. midterm elections has passed $2.5 billion, putting the platform close to twice the $1.3 billion it recorded during the 2024 election cycle.

At the $2.5 billion threshold, turnover is at least $1.2 billion, or roughly 92%, above Kalshi’s 2024 figure, based on arithmetic from the company’s numbers. The comparison measures trading in the contracts, not company revenue, customer deposits or the capital traders stand to gain or lose.

What does the $2.5 billion cover?

Kalshi’s 2026 markets span contests for the U.S. House and Senate, governor offices and state posts including attorney general, lieutenant governor and secretary of state. The range gives the total a broader base than a single national race, combining federal contests with state-specific elections.

That breadth also changes how the headline should be read. A total assembled across House, Senate, gubernatorial and state-office contracts reflects aggregate turnover, so it cannot show how much activity came from any one race or whether the same traders drove volume across several contracts.

Kalshi’s disclosure does not provide contract-level turnover, trader counts or open interest. Market participants therefore get a clear measure of aggregate event volume but limited evidence on participation, concentration or how much liquidity sits in each market.

What does the 98% accuracy claim show?

By early Nov. 4, Kalshi said its contracts favored candidates who won 479 races, an accuracy rate of about 98%. The statement measures the candidates the market favored, rather than every outcome produced by the platform, and the company did not list the underlying races in the disclosure.

The metric gives prospective traders a reference point for the platform’s election-market performance. It does not disclose the number of losing favorites, the count of unresolved contracts or the method Kalshi used to calculate the rate, so the 479 wins and 98% figure cannot be independently reconstructed from the information provided.

For Kalshi, the accuracy claim carries business weight because a prediction market depends on traders judging whether prices reflect likely outcomes. The Nov. 4 cutoff also makes the result a snapshot, not a final record for all contracts linked to the 2026 election cycle.

How does this compare with 2024?

Kalshi places 2024 election-cycle volume at $1.3 billion. Earlier coverage of the midterm market recorded a $1.4 billion volume milestone. It does not reconcile the two figures, leaving the relationship between the retrospective total and the earlier milestone unspecified.

The current $2.5 billion disclosure supports a direct comparison with Kalshi’s own $1.3 billion cycle figure: it is more than $1.2 billion higher and nearly 1.9 times as large. The $1.4 billion reference should not be treated as the same series without a definition of scope or timing.

Operationally, the scale makes election contracts a more significant part of Kalshi’s activity than the prior cycle. That does not establish that revenue or customer retention rose at the same rate. The disclosure gives no take rate, fee income, trader count or profitability data, and it does not show how much activity will remain after voting ends.

The broader race menu spreads Kalshi’s activity across a multi-office election calendar. Its contracts span several layers of government, from congressional contests to governors and other statewide offices. The practical test is whether that breadth produces sustained trading and dependable settlement records, not simply a larger headline total.

What comes next?

The next checkpoint is the resolution of the 2026 races, when a final volume total and a complete win-loss record would give market participants a firmer basis for comparing this cycle with Kalshi’s 2024 performance.
