Infiniti Briefing

Kalshi recorded $2.32 billion in trading volume for Monday, Oct. 12, according to Dustin Gouker’s Oct. 14 prediction-markets newsletter at nexteventhorizon.substack.com. The figure is a dated daily snapshot, rather than a measure of trading on Oct. 14.

Volume and product mix

The supplied headline puts parlays at 62% of Kalshi’s flow. However, the accompanying newsletter does not include that percentage or explain its calculation. The daily volume total is supported by the source; the parlay share cannot be independently checked against the supplied reporting.

That distinction matters when assessing the platform’s activity. Without a definition of “flow” or a methodology for the parlay figure, readers cannot establish whether the 62% share uses the same measurement basis as the $2.32 billion total. The material also provides no comparable daily series from which to determine a growth rate.

Sports remain central

Separate survey findings point to sports’ prominence among prediction-market users. According to Casino.org, as summarized in Gouker’s newsletter, the S&P Global Market Intelligence Kagan US third-quarter 2026 Consumer Insights survey found that 10% of respondents had traded on a yes/no exchange over the past year. Among prediction-market users, 70% had traded sports event contracts. Those figures measure participation, not trading volume, and do not validate the headline’s parlay share.

What it means for prediction markets

• Keep the dates aligned: The $2.32 billion figure covers Monday, Oct. 12, not the article’s Oct. 14 publication date.
• Treat the product split cautiously: The 62% parlay figure appears in the supplied headline but lacks supporting methodology in the accompanying source.
• Separate participation from turnover: The survey’s 70% sports participation finding provides context for product demand, not a measure of sports’ share of dollars traded.
