Kalshi set back-to-back daily volume records of $3.91B and $3.96B, with combos near 70% of flow

Kalshi recorded daily trading volume of $3.91B on Oct. 10, 2026, followed by $3.96B on Oct. 11, setting consecutive records. According to infobets.com, citing Crypto Briefing, combo contracts accounted for roughly 70% of trading.

Combos dominate the records

Both days exceeded the previous $3.68B peak reached on Oct. 4. Combo contracts contributed about $2.80B on Oct. 10 and $2.75B on Oct. 11, making them the largest component of the record totals.

The figures require a distinction between notional activity and money committed. According to infobets.com, the reported volume measures the full potential payout of contracts rather than the cash traders put at risk.

Many parlay-style combos were priced below 1 cent, the outlet reported. That means the money committed to those positions was substantially smaller than their contribution to headline volume.

Regulatory treatment is the key question

Kalshi is a CFTC-regulated prediction market, but infobets.com highlighted the resemblance between its sports combos and sports betting, which is regulated state by state in the US. The concentration of activity in these products makes their regulatory treatment particularly relevant to the platform’s growth.

The issue to monitor is whether a ruling treats Kalshi’s sports combo contracts as prediction-market products or sports wagers. Restrictions could affect the contracts responsible for most of the reported trading, though the supplied reporting identifies no new ruling.

What it means for prediction markets

• Volume is not cash exposure: The $3.91B and $3.96B records reflect potential payouts, not equivalent amounts of money at risk.
• Product mix matters: Combos generated roughly 70% of activity, so aggregate volume alone offers an incomplete picture of trading across Kalshi’s markets.
• Classification could affect activity: Any ruling on the treatment of sports combos could have an outsized effect on the products driving the record totals.
