Kalshi and Polymarket US reach record trading volumes during October

Crypto Economy reported Kalshi reached about 65 billion dollars in October volume and Polymarket US approached 10 billion dollars, both monthly highs ahead of the November 3 midterms. DefiLlama trailing 30-day figures cited were 89.77 billion dollars for Kalshi and 13.62 billion dollars for Polymarket US.

October volumes reach new highs

Kalshi and Polymarket US posted record monthly trading volumes in October ahead of the November 3 midterms, according to Crypto Economy.

Kalshi recorded about 65 billion dollars in October volume, while Polymarket US approached 10 billion dollars. Both figures represented monthly highs, Crypto Economy reported.

Monthly and trailing figures differ

The report also cited DefiLlama figures showing trailing 30-day volume of 89.77 billion dollars for Kalshi and 13.62 billion dollars for Polymarket US.

Those trailing totals are distinct from the reported October figures. The supplied summary does not explain the difference, so the two sets should not be treated as interchangeable measures of monthly activity.

What it means for prediction markets

  • Both platforms reached reported monthly volume highs ahead of the November 3 midterms, making trading activity a key backdrop to the election markets.
  • Kalshi’s reported volume exceeded Polymarket US’s in both the October and trailing 30-day figures.
  • The figures describe trading volume, not election probabilities. They do not, by themselves, establish which outcomes traders expect.
