How we collect data

DeFi Rate pulls prediction market data directly from platform APIs on a rolling basis. Kalshi data is sourced from the Kalshi REST API, which provides market-level contract data including volume, open interest, resolution status, and native category classifications. Polymarket data is sourced from the Polymarket GraphQL API, which exposes market-level trading activity, liquidity, and outcome probabilities across its decentralized order book. We also support ForecastX, Gemini and Polymarket US, though the data provided is limited in scope compared to Kalshi and Polymarket (international)

Data is fetched at 30-minute intervals, cleaned and stored on our end. All figures reflect each platform’s public API at the time of the most recent refresh.

Volume methodology

All volume figures are calculated on a rolling window basis, not calendar periods. A 24-hour rolling window captures all trades recorded in the 24 hours preceding each data pull. A 7-day window covers the trailing 7 days; a 30-day window covers the trailing 30 days. Figures update continuously and will differ from calendar-period totals (e.g., “volume this month”) published elsewhere.

Volume is denominated in USD. Kalshi reports native USD figures. Polymarket volume is denominated in USDC and converted to USD at a 1:1 rate, consistent with USDC’s peg.

Category taxonomy

Kalshi categories reflect the platform’s native classification system as returned by the Kalshi API. Polymarket does not enforce a rigid native taxonomy; categories displayed for Polymarket markets are assigned by DeFi Rate using a standardized classification schema mapped against market title and tag data. The schema assigns each market to one of the following categories: Politics, Sports, Crypto, Economics, Finance, Tech, Culture, Weather, Misc, and World. Markets carrying Polymarket’s native “mentions” tag are classified separately as Mentions. Category assignments are reviewed periodically and updated when platform tagging changes.

Leading outcome

The Leading column in the Top Markets table displays the current frontrunner for each market. For binary markets, this is the outcome trading above 50% implied probability. For multi-outcome markets, it is the outcome with the highest current implied probability. The probability figure shown reflects the last traded price for that contract. “Outcome” in place of a probability indicates the market has resolved and the displayed entry is the confirmed result.

Status definitions

Active markets are open for trading at the time of the data pull. Closed markets have passed their end date or been resolved by the platform. DeFi Rate does not distinguish between platform-level “expired” and “settled” statuses in the display layer; both appear as Closed.

Polymarket US top 30 markets

The Polymarket US Top 30 tab filters to markets accessible to US-based traders under Polymarket’s geofenced access rules. Polymarket restricts certain political and financial markets from US IP addresses; this view reflects the subset of the Polymarket top 30 reachable from a US connection at the time of the data pull. Availability is determined by Polymarket’s own access-control layer and may change without notice.

Change percentage

The change figure displayed alongside each volume metric is the percentage difference between the current rolling window and the equivalent prior period. For a 30-day reading, the comparison window is days 31–60 immediately preceding the current window. A positive value indicates higher volume in the most recent window; a negative value indicates lower volume. Change figures apply at the platform level, category level, and individual market level depending on context.

Market count figure

The Markets figure in the Category Breakdown table reflects the total number of discrete contracts within each category, not the number of parent events. On Kalshi, a single event (e.g., “NBA Champion 2026”) may contain multiple contracts — one per team — and each is counted separately. On Polymarket, each market URL corresponds to a single binary outcome and is counted as one market. Kalshi market counts are therefore not directly comparable to Polymarket market counts at the category level, though this is often used in the media.

Open interest

Open interest reflects the total value of unsettled contracts currently held by traders on a given market. It is pulled directly from each platform’s API and represents outstanding exposure at the time of the data pull, not cumulative traded volume. A dash (—) in the Open Int. column indicates the field was not returned in the API response for that market.
