Kalshi secures $1 billion as valuation reaches $40 billion

Hedgeweek, reporting on November 4, says Wellington and Sequoia Capital co-led the round, with Coatue and Balyasny confirmed as participants and Millennium and Tiger Global identified by Crunchbase. Kalshi reports more than 30 million registered accounts, more than 1 trillion dollars in annualised trading volume, a market share above 75 percent, and non-sports annualised revenue above 1 billion dollars.

Kalshi raised $1 billion in a Series G funding round at a $40 billion valuation, according to Hedgeweek’s November 4, 2026 reporting. The valuation is nearly double that of its prior round.

Investors behind the round

Wellington and Sequoia Capital co-led the financing, according to Hedgeweek. Coatue and Balyasny were confirmed as participants.

Millennium and Tiger Global were also identified as investors by Crunchbase. That attribution distinguishes them from the participants confirmed in Hedgeweek’s reporting.

Kalshi’s reported scale

Kalshi reports more than 30 million registered accounts and more than $1 trillion in annualised trading volume. It also puts its market share above 75 percent.

The company reports non-sports annualised revenue above $1 billion. The supplied summary does not specify the basis for the market-share calculation or the periods used to annualise trading volume and revenue.

What it means for prediction markets

  • The $1 billion financing and nearly doubled valuation mark a substantial increase in investor backing for Kalshi.
  • Kalshi’s account, volume and market-share figures indicate its reported scale, but registered accounts should not be read as a measure of active traders.
  • Non-sports annualised revenue above $1 billion is a distinct indicator of activity beyond sports; it is an annualised figure, not a stated full-year revenue result.
