According to an analysis by Odaily Odaily, the boom in the US prediction market is built on an unstable foundation, primarily benefiting from regulatory arbitrage opportunities. For example, currently, US states lack comprehensive regulations to oversee user participation in sports betting through prediction markets. Dune Analytics data shows that in 2025, sports-related transactions will account for approximately 85% of Kalshi's trading volume, while Polymarket will account for approximately 39%. Devin Ryan, Head of Financial Technology Research at Citizens Bank, believes the market needs to establish robust integrity rules, and trading volume in non-sports markets needs to increase. Currently, the market size for predicting January CPI inflation data on Kalshi is less than $1 million, and the market size for predicting core inflation is less than $30,000. Such liquidity is insufficient to attract institutional participation.
Furthermore, the current US prediction market exhibits characteristics of a "fragile boom," with growth primarily reliant on regulatory gray areas and substantial marketing investment. Growth could come under pressure should regulations tighten or user interest decline. There is also some bargaining at the regulatory level. For example, US prediction markets typically claim to be regulated by the Commodity Futures Trading Commission (CFTC) as event-driven contract trading, but state-level regulators are more cautious, and related legal disputes may ultimately reach the Supreme Court for adjudication.
