Kalshi chases midterm growth after World Cup surge

• Kalshi has launched a Midterms Hub tracking Senate and House races through live market-implied probabilities.
• The 2026 FIFA World Cup brought the platform 3 million new users and a record $1.2bn single-market volume.
• The push comes amid CFTC contract proposals and state injunctions in Washington, Michigan, Massachusetts and Nevada.

Kalshi has launched a dedicated hub for the 2026 US midterm elections, seeking to convert record FIFA World Cup engagement into sustained growth across its political event markets.

The prediction market operator added 3 million new users during the tournament, with more than $1.2bn traded on its World Cup winner contract alone.

The Midterms Hub combines live prediction market prices with polling data, fundraising figures and historical election results, giving users a single destination for tracking the campaign season, according to the company.

Visitors can follow Senate and House races through market-implied probabilities rather than traditional opinion polls. Kalshi said the platform is built to offer a real-time, data-driven view of the races as campaigning intensifies ahead of November.

The launch caps a landmark period for the operator. Kalshi told CNBC the World Cup delivered 3 million new users, and its tournament winner contract generated more than $1.2bn in trading volume, the largest single market in the company’s history.

The company also said overall World Cup trading on the platform exceeded $12bn, a tournament run that reshaped its user base and set new internal records.

Beyond sports contracts

The operator is widening its product range beyond sports-style event contracts as it looks to smooth out activity between major sporting events. The US Commodity Futures Trading Commission (CFTC) recently approved perpetual futures contracts, initially linked to cryptocurrencies, marking a significant expansion of what the platform can list.

Kalshi has also introduced markets tied to FDA drug trial outcomes and is pursuing approval for contracts based on precious metals, a diversification drive that follows reports the company is exploring a public listing.

Regulatory headwinds

The growth push continues against sustained scrutiny at both federal and state level.

The CFTC has proposed banning contracts linked to war, terrorism, assassination and illegal activities, alongside certain sports markets considered vulnerable to manipulation. The proposals would narrow the range of products prediction markets can list under federal oversight, and they arrive just as Kalshi leans harder into its highest-profile categories.

At state level, Washington has secured a preliminary injunction preventing Kalshi from offering event contracts within its borders. It joins Massachusetts, Michigan and Nevada in challenging the platform on the grounds that its contracts resemble unlicensed sports betting, keeping the question of who regulates event trading firmly in the courts as the election season approaches.

Information over trading

Kalshi argues its election products carry value beyond speculation, positioning the platform as an alternative source of political forecasting alongside conventional polling.

According to the company, around 75 percent of visitors use the platform to monitor live probabilities rather than buy or sell contracts. Both CNBC and CNN have featured Kalshi’s live market probabilities in political and financial coverage, a sign of growing mainstream traction for prediction markets.

Kalshi has admitted before that volumes sag once a big tournament ends. The midterms are its answer this time: a story that builds for months rather than weeks, with a resolution date already circled in November. If the hub keeps World Cup converts trading, or even just watching, through election night, the company will have found something no sporting calendar can offer.
