Kalshi’s $1 billion Series G draws major investment firms

AlphaMaven, citing a Hedgeweek report, says Coatue and Balyasny are confirmed participants in Kalshi's 1 billion dollar Series G round and Millennium and Tiger Global are identified as investors by Crunchbase, in a round co-led by Wellington and Sequoia Capital at a 40 billion dollar valuation. Kalshi reports more than 1 trillion dollars in annualised trading volume and over 30 million registered accounts.

Kalshi’s $1 billion Series G funding round values the prediction-market platform at $40 billion, according to AlphaMaven, which cites a Hedgeweek report. Wellington and Sequoia Capital co-led the round.

Investor participation has different sourcing

Coatue and Balyasny are confirmed participants, according to the AlphaMaven account of Hedgeweek’s reporting. Millennium and Tiger Global are identified as investors by Crunchbase.

That distinction matters when assessing the investor roster: the supplied reporting attributes participation to different sources, rather than presenting all four firms as confirmed through the same channel.

Kalshi reports substantial platform activity

Kalshi reports more than $1 trillion in annualised trading volume and over 30 million registered accounts. Those figures describe the platform’s reported scale alongside the financing.

The annualised volume figure is not a statement of completed calendar-year trading, while registered accounts do not establish how many users are active. The supplied summary provides no further breakdown of either measure.

What it means for prediction markets

  • The $40 billion valuation provides a financing benchmark for Kalshi, distinct from its reported trading volume and account count.
  • Readers tracking institutional participation should retain the sourcing distinction between Coatue and Balyasny and the Crunchbase-identified investors, Millennium and Tiger Global.
  • Kalshi’s reported scale does not, by itself, establish liquidity or participation levels in individual prediction markets.
