Nine prediction exchanges tally $6.1 billion on rolling daily measure

Prediction-market activity reached $6.1 billion over a rolling 24-hour period across nine exchanges tracked by DeFi Rate, according to the outlet’s Today page.

The latest observation was recorded at 4:56 AM ET on November 1, 2026. The report was published on Nov 1, 2026, at 5:00 AM ET.

How the total is measured

DeFi Rate calculates the figure by counting contracts at one dollar each. That convention is important when interpreting the headline total: the reported measure reflects a fixed value assigned to each contract.

The tally covers all categories on the nine tracked venues, including Kalshi and Polymarket. The supplied summary does not provide individual exchange totals or a breakdown by category.

A rolling snapshot

The $6.1 billion figure captures the preceding 24 hours rather than a completed calendar day. It is therefore a snapshot tied to the observation time, not a final total for November 1.

What it means for prediction markets

• Measurement matters: The one-dollar-per-contract convention defines the reported total; the summary does not establish how much cash changed hands.
• Coverage has limits: The figure aggregates nine tracked exchanges, not necessarily the entire prediction-market industry.
• Activity is not direction: Without category, contract or price data, the aggregate does not show which outcomes traders favored or how probabilities changed.
