Weekly volume analysis
Fed Rate Hike Nears Certainty After Hotter Inflation Report
Prediction markets sharply increased the odds of a September Federal Reserve rate hike after core inflation rose more than expected on Sept. 11. DeFi Rate’s cross-venue probability for a 25-basis-point increase climbed from 63.7% to 81.3% in 24 hours, while total volume across the decision reached $192.6 million on Kalshi and Polymarket Global. Polymarket US also self-certified contracts for the meeting Friday.
Patriots-Seahawks Prediction Market Volume Jumps from $5.8M to $105.5M in 24 Hours

Prediction Markets Grow 14% As NFL Season Sets Up Major Growth
Prediction markets hit $12.9B in weekly volume as Kalshi takes 92% share, while the NFL season could drive billions more in prediction market trading.
Prediction Market NFL Trading Volume Could Reach $57 Billion This Season
DeFi Rate projects Kalshi NFL trading volume will reach roughly $3.2 billion through Week 1 and $57 billion across the full 2026–27 season. The forecast reflects the sharp expansion in prediction-market participation and NFL contract inventory over the past year, while using last season’s week-by-week trading pattern to model how volume is likely to build across the season rather than extrapolating the current growth rate indefinitely.
Prediction Markets Top $11B in Contract Volume as Sports, Combos Drive Kalshi Growth
Prediction markets surged to $11.26B weekly contracts as Kalshi set a record, grabbed 90.4% market share, and powered growth through sports and combo markets.

KalshiHow 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.
