Gate News message, April 28 — Kalshi’s weekly trading volume reached $3.4 billion in the week ending April 26, marking an all-time high for the prediction market platform, according to Artemis data. Sports trading alone accounted for $3 billion, or 88% of total volume, exceeding Polymarket’s entire weekly volume by roughly $1 billion.
Kalshi’s other categories recorded significantly lower volumes: crypto markets generated $334.1 million while politics accounted for just $16.8 million. In comparison, Polymarket’s $1.4 billion weekly volume was distributed more evenly across categories, with sports at $959.1 million, politics at $507.3 million, and crypto at approximately $416 million. The disparity in politics is particularly stark—Polymarket recorded $507.3 million versus Kalshi’s $16.8 million, roughly a 30-to-1 gap.
Kalshi’s growth has been dramatic, with weekly volumes expanding 42-fold from $80.5 million a year ago. The platform has positioned itself as a sports-focused alternative to traditional betting, competing with platforms like DraftKings and FanDuel through prediction market contracts on NBA, NFL, and other major sports. Polymarket maintains structural advantages in political and macro event trading due to its global user base and longer operating history in those categories.
