Kalshi discloses account total above 30 million as annualised volume tops $1 trillion

The figures appear in Alpha Finance's prediction market statistics roundup, updated November 4, which traces its platform figures to primary sources and exchange disclosures. Kalshi is the largest US prediction market exchange by reported contract volume.

Kalshi says more than 30 million accounts have been opened and its annualised trading volume exceeds 1 trillion dollars, according to Alpha Finance.

The figures appear in Alpha Finance’s prediction market statistics roundup, updated November 4. The summary highlighting those figures was published Nov 7, 2026, at 12:45 PM ET.

Reported scale and sourcing

Alpha Finance’s roundup traces its platform figures to primary sources and exchange disclosures. The account and annualised trading-volume totals are presented as Kalshi’s reported figures.

Kalshi is the largest US prediction market exchange by reported contract volume, according to Alpha Finance. That ranking concerns contract volume; the account total is a separate measure of the platform’s scale.

What it means for prediction markets

  • Keep the measures distinct: More than 30 million opened accounts does not establish how many accounts are actively trading or how many individual traders they represent.
  • Read the volume figure carefully: Annualised trading volume above 1 trillion dollars is not the same as a disclosed total for a completed year.
  • Retain the reporting qualification: Kalshi’s lead among US prediction market exchanges is based on reported contract volume.
