Kalshi Election Day Volume Hits $4.15 Billion, Below October Record

Kalshi recorded $4.15 billion in notional trading volume on Election Day, Nov. 3, marking its biggest weekday session, according to Bitcoin.com News. The total nevertheless fell short of the platform’s $5.3 billion record on Saturday, Oct. 24, showing that the election-day milestone did not translate into an overall trading high.

The gap between the two sessions was $1.15 billion, putting Election Day volume about 22% below the October peak. Those comparisons distinguish two measures of activity: Nov. 3 established a weekday record, while Oct. 24 remained the larger session regardless of the day of the week.

The composition of trading also changed substantially between the sessions. Parlay-style combos accounted for 58.6% of Election Day volume, down from about three-quarters on the record day, while single-market contracts played a larger role. Bitcoin.com News described those single-market contracts as doing the lifting in the Election Day session.

Combos still represented a majority of notional volume on Nov. 3, despite their smaller share. The shift therefore points to a less combo-heavy session rather than a disappearance of that activity. Using the reported share, combos accounted for approximately $2.43 billion of Election Day volume, with the remainder totaling about $1.72 billion.

The figures also illustrate why total volume and trading mix need to be considered separately. A platform can register a significant session even when the types of contracts generating activity differ from those behind an earlier peak. In this case, the weekday record coincided with a lower proportion of combo trading than on Oct. 24.

Notional volume measures the stated value of trading activity; it should not be read as platform revenue or the amount traders collectively earned. The supplied report does not provide those financial measures, nor does it identify how many traders participated. Consequently, the headline total alone cannot establish whether a broader user base drove the session.

The Election Day timing also does not establish that election-related contracts accounted for the reported volume. The supplied material gives an overall platform figure and a comparison of contract formats, but no breakdown by underlying subject. It therefore supports conclusions about the session’s size and composition, rather than which individual markets attracted the most trading.

The next point of comparison will be whether subsequent sessions exceed the $5.3 billion benchmark or sustain the larger single-market share seen on Nov. 3. The supplied report offers no forecast for either outcome. For now, its figures leave Kalshi with a new weekday high and an October session that remains the overall record.
