Prediction markets log $115.8 billion as monthly trading accelerates

Prediction-market notional trading volume totaled $115.8 billion in the 30 days through October 25, according to HackerNoon, citing Prediction Frontier’s Markets dashboard.

The total was 61.5 percent higher than in the preceding 30-day period, marking a substantial increase in aggregate trading across the venues covered.

What the figures cover

Prediction Frontier’s dashboard draws on Dune data and combines trading across major event-contract venues, according to HackerNoon. The reported total is therefore a cross-venue measure rather than a figure for a single market or platform.

The report was published on November 4, 2026, at 8:30 AM ET, while the underlying data runs through October 25. That cutoff matters when interpreting the number: it describes a completed 30-day window, not activity through publication.

What it means for prediction markets

• The 61.5 percent increase establishes that aggregate notional volume expanded sharply against the preceding 30-day period.
• The supplied figures do not break out individual venues or contracts, so they do not identify which markets drove the increase.
• This is a measure of trading volume, not contract prices or implied probabilities; it does not establish a shift in expectations for any particular event.
