Dune prediction market dashboards: what they show, what they cost, where they stop

What it does

The dashboard aggregates on-chain and exchange data for 11 venues: Kalshi, Polymarket (including the US version), Opinion, Limitless, Predict, Overtime, Gemini, Myriad, ForecastEx, Crypto.com and Hyperliquid.

Headline tiles at fetch time showed 4,425,677 unique users, about $1.34 billion of open interest, about $369.76 billion of notional volume, about $127.36 billion of taker volume and 2.25 billion transactions. Monthly trend charts sit underneath.

• Metrics: total notional volume, taker volume, USD volume, open interest, unique users, transaction counts
• Monthly charts from January 2024 to September 2026
• Linked sub-dashboards for individual venues and for market accuracy

Pricing

Viewing the dashboard is free. Dune charges for query credits and API access on its own plans, which only matter if you fork the queries or want to pull the data programmatically.

Venues and data

The author flags a methodology point on the page itself: "Use Taker Volume as a proper standard of fair comparison." Notional volume double-counts in ways that differ by venue, so the taker series is the one to compare across Kalshi and Polymarket.

Because the SQL is public you can open any chart, read the query and check how a number was built. That is the main reason to trust a Dune chart over a screenshot.

Where it falls short

There is no market-level view. You get venue totals and monthly trends, not the price history of a single contract.

Dashboards depend on volunteer maintenance. Another Dune dashboard on Polymarket category volume returned SQL errors on every widget when fetched, so check that a chart shows a successful run before quoting it.

Who should use it

Anyone writing about or allocating across venues: which exchange is taking share, how much open interest exists, how many users are active. Traders looking for a single market's chart should use a venue-specific tool instead.
