The 2026 U.S. congressional general election is Tuesday, November 3, 2026. This 2026 midterm election calendar and Kalshi contract checklist separates that federal date from state voting deadlines and the rules governing individual prediction-market contracts. Sources and Kalshi API availability were checked on August 18, 2026.
Primary sources checked: the official GovInfo text of 2 U.S.C. § 7, the USA.gov midterm election page, the USA.gov registration deadline guide, and the National Governors Association election page.
Source snapshot: This page was checked on August 18, 2026, from 06:15 to 06:25 UTC, 77 days before Election Day. Registration deadlines, voting procedures, market availability, prices, fees, and contract terms can change, so readers should reopen the official sources before acting.
Election Day is Tuesday, November 3, 2026. Federal law schedules the election of Representatives and Delegates for the Tuesday after the first Monday in November of every even-numbered year. In 2026, the first Monday is November 2, making the following Tuesday November 3.
That date does not create one national deadline for registration, mail ballots, or early voting. USA.gov says registration deadlines vary by state and can fall as much as a month before an election. Voters should use Vote.gov and the relevant state or territory election office rather than relying on a general calendar.
Election Day is also not automatically a Kalshi settlement date. A contract may depend on a later event, verification condition, or source specified in its rules. A race call, concession, preliminary count, certification, or congressional action should not be treated as controlling unless the exact contract says so.
USA.gov says all 435 U.S. House seats are up for election in each midterm and presidential election year. It also says roughly one-third of the U.S. Senate is elected every two years. This guide does not substitute an unsupported precise count of 2026 Senate contests or special elections.
The National Governors Association lists 39 gubernatorial elections across states and U.S. territories in 2026. That should not be shortened to 39 state races because the official list includes territories.
Individual ballots may also contain state legislative, local, judicial, or ballot-measure contests. Their presence and wording depend on the jurisdiction. Kalshi should not be assumed to offer a contract for every House, Senate, governor, local, or ballot-measure race.
For narrower coverage, use the separate 2026 Senate-control source checklist, House markets guide, and 2026 primary election guide.
At the August 18, 2026 snapshot, Kalshi’s public Elections catalog and exact market endpoints returned active election-cycle contracts covering House control, the 2026 House popular-vote margin, Speaker of the 120th House, and post-midterm governor balance. The checked House-control API endpoint returned an active market at that time.
Those dated checks establish election-cycle relevance only. They do not establish present availability, a price, liquidity, eligibility, fees, close time, expiration, payout terms, or the date and method of settlement for any reader.
Before trading any 2026 election contract, check:
Kalshi states that every market has its own rules, outcome criteria, and verification source. The Kalshi Market Rules guide and market outcomes guide explain the framework, but the exact contract page controls. Treat this 2026 midterm election calendar and Kalshi contract checklist as a verification process, not as a substitute for those terms. Updates and related market notes are also posted through the @Kalshi_market channel.
The 2026 U.S. congressional general election is Tuesday, November 3, 2026. GovInfo provides the federal statutory schedule, and USA.gov confirms that the midterms occur in November 2026. Registration, early-voting, and mail-ballot deadlines are separate and vary by state or territory.
All 435 U.S. House seats and roughly one-third of the U.S. Senate are involved, according to USA.gov. The National Governors Association also lists 39 gubernatorial elections across states and territories. State legislative, local, judicial, and ballot-measure contests depend on each jurisdiction’s official ballot.
Official API checks found active election-related contracts on August 18, 2026, including contracts within several House, Speaker, and governor-related series. That dated snapshot does not prove current availability for any reader. Check Kalshi directly for the latest contract list, account eligibility, prices, fees, liquidity, and rules.
There is no universal settlement time for Kalshi election contracts. Each market has its own outcome criteria and verification source. Traders should not assume settlement occurs on Election Day, at poll close, after a media call, following a concession, or upon certification unless the exact contract rules specify that condition.
Not financial advice. Prediction-market trading is speculative, and you can lose money. Do your own research.
