Kalshi dominates tracked trading as November 5 turnover tops $2 billion

According to DeFi Rate’s volume tracker, trading across the venues it monitors reached $2.12B so far on November 5, 2026. The supplied update was published at 11:24 AM ET.

Kalshi accounted for $1.88B of that total, making it the dominant contributor to the tracked activity.

A partial-day view

The figures represent trading recorded so far, rather than a completed daily total. They also cover only the venues included in DeFi Rate’s tracker, not necessarily the entire prediction-market industry.

The supplied summary begins to reference Polymarket’s international venue but ends before providing its volume. That leaves the available breakdown incomplete beyond Kalshi’s contribution.

What it means for prediction markets

• The snapshot shows activity heavily concentrated on Kalshi within the tracked venues; it does not establish whether that concentration will persist.
• The $2.12B figure is an interim total. Comparisons with completed trading days would need to account for the different measurement windows.
• Aggregate venue volume does not reveal which contracts attracted trading or how event probabilities changed.
