Blask data shows US prediction market demand up more than fivefold since August 2025

Blask said new analysis shows branded demand for prediction markets in the United States has increased more than fivefold since August 2025, based on the firm’s tracking of the category through March 2026.

The firm said current demand remains about 49% below the all-time high recorded during the November 2024 US election cycle, which it characterized as an event-driven spike. Blask said the latest rise has built steadily over eight consecutive months “without a comparable macro trigger.”

Blask also announced a dedicated prediction market analytics feature that it said allows operators to track demand dynamics, competitive positioning, and regional distribution in real time, including state-level benchmarking.

Blask said Polymarket and Kalshi together account for about 94% of all branded demand in US prediction markets as of March 2026. In Kansas, Blask reported Polymarket at 95.5% of branded demand versus Kalshi at 3.5%, while Louisiana was the closest contest it cited, at 59% for Polymarket and 35.3% for Kalshi.

Outside the two leaders, Blask said the rest of the market accounts for 6% of total branded demand, with Myriad under 1%. The firm also said Robinhood is the fastest-growing brand in the category, reporting year-over-year growth of +983.4% while holding a 0.24% share. Blask added that demand is geographically concentrated, led by California at 15.9% and New York at 10.8% of total US branded demand.
