The first full week of April brought a surge of activity across prediction markets, driven by shifting expectations around the Federal Reserve's next rate decision and a wave of new market launches across platforms. Here is what moved this week.
Fed Rate Decision Markets See Heightened Volatility
Markets pricing the May 2026 FOMC meeting moved sharply this week after a stronger-than-expected March jobs report landed on Friday. On Kalshi, the "Fed holds rates at May meeting" contract swung from $0.62 to $0.74 over three trading sessions as traders repriced the likelihood that the Fed will delay its first cut of the year. The implied probability of a May cut dropped from 38% to 26% in the span of 48 hours.
The volatility spilled into June and July rate contracts as well. June cut probability fell from 71% to 58%, while the "at least two cuts by September 2026" contract dropped below 50% for the first time since February. Traders following a news trading approach found opportunities in the rapid repricing, with several contracts moving 8-12 cents within minutes of the jobs data release.
Economic data continues to be the primary catalyst for rate markets, and the next major test comes with the March CPI report due April 10. Traders are positioning early, with open interest on inflation-related contracts climbing 22% week-over-week.
Kalshi Hits Record Daily Volume
Wednesday marked a new single-day volume record for Kalshi, with the platform processing over $412 million in notional volume across all markets. The previous record of $389 million was set during the November 2025 election cycle. Sports markets accounted for roughly 45% of the total, followed by economics at 28% and politics at 15%.
The milestone underscores Kalshi's continued dominance in the US regulated prediction market space. The platform now handles roughly two-thirds of all regulated prediction market volume in the United States, a position it has held since overtaking PredictIt in late 2024. Year-to-date volume through the first quarter of 2026 is tracking 180% ahead of the same period last year.

FanDuel Predicts Launches New Sports Markets
FanDuel Predicts expanded its market offerings this week with the addition of several new sports categories. The platform added full coverage for the 2026 MLS season, including match outcomes, season win totals, and MVP markets. FanDuel also introduced a set of individual player performance markets for the MLB season, allowing traders to take positions on specific stat thresholds for pitchers and hitters.
The MLS markets are notable because they fill a gap that other platforms have largely ignored. Neither Kalshi nor Robinhood currently list MLS markets, giving FanDuel a temporary edge with soccer-focused traders. The player performance contracts follow a model that has proven popular in the DFS world — prop-style markets tied to individual athletes rather than team outcomes.
FanDuel's mobile experience remains one of the best in the industry, and these new markets benefit from the same polished interface that sports bettors already know. Read our full breakdown in the FanDuel Predicts review.
Polymarket Expands Climate and Weather Markets
Polymarket added a dedicated climate and weather section to its platform this week, listing 14 new markets covering hurricane season forecasts, monthly temperature anomalies, and wildfire severity for the 2026 season. The move positions Polymarket to compete more directly with Kalshi in weather markets, an area where Kalshi has historically dominated among regulated platforms.
The new markets include contracts on whether 2026 will be the hottest year on record globally, the number of named Atlantic hurricanes exceeding 20, and whether any single US wildfire will burn more than 500,000 acres. Early trading has been active, with the "hottest year on record" contract sitting at $0.67 after its first full day of trading.
Climate markets are a growing niche in the prediction market space. They attract a different audience from politics or sports traders — researchers, weather enthusiasts, and increasingly, institutional participants interested in hedging climate-related risk. Polymarket's crypto-native settlement makes these markets accessible globally, though US residents should review the legality guide for restrictions.
Top Market Movers of the Week
A quick look at the largest price movements across major platforms this week:
Economics. The "Fed cuts in May" contract fell from $0.38 to $0.26 on Kalshi after the strong jobs report. The "US enters recession in 2026" contract dropped to $0.14, its lowest level since being listed.
Politics. Midterm election markets remained relatively stable, though the "Republicans hold House in 2026" contract ticked up two cents to $0.57. The "Biden approval above 45% by June" contract held steady at $0.31.
Sports. NBA playoff markets saw the most action as the regular season winds down. The "Celtics win 2026 NBA Championship" contract rose from $0.18 to $0.24 after a seven-game winning streak. The "Thunder win Western Conference" contract remained the most-traded sports contract on Kalshi at $0.29.
Weather. The "above-normal Atlantic hurricane season" contract on both Kalshi and Polymarket settled around $0.72, reflecting the consensus among forecasters for an active 2026 season.
What to Watch Next Week
The March CPI report on Thursday will be the single most important data point for prediction markets. A hotter-than-expected reading could push May rate cut probability below 20% and trigger significant moves across economic contracts.
