ParlayX is developing individual logins, delegated permissions and subaccounts for such teams. Other gaps include unified execution across exchanges, prime brokerage and common resolution standards.
A contract purchased on Kalshi cannot simply be transferred and sold on Polymarket, even where the two markets appear to cover the same outcome. Each exchange may also define and resolve its contracts differently, creating an additional risk for firms trading across venues.
Liquidity can consequently become self-reinforcing. Market makers gravitate towards platforms offering dependable technology and substantial order flow, while their participation improves pricing and execution for consumers.

Beginning with the US presidential elections in November 2024, when prediction markets catapulted into mainstream culture, their rise has been undeniable. Kalshi and Polymarket have seen their valuations balloon to $40 billion and $21 billion, respectively, and the majority of the top US bookmakers have scrambled to expand into the prediction space in various forms, either by building their own exchanges, acquiring existing ones or engaging in market-making.
Commercial sports betting generated just under $17 billion in nationwide revenue in 2025, which is why Davenport asserts that the “stakes of this case are exceptionally high”. Kalshi and Polymarket alone posted more than $45 billion in trading volume, which is similar but not identical to betting revenue, in August. That was a 15% decline from July, although that drop is attributed to the conclusion of the Fifa World Cup tournament that month per Yahoo! Finance.
The American Gaming Association estimates that the exchanges have siphoned more than $1.3 billion in would-be tax revenue from states. One of the AGA’s primary spokespeople pin its fight against prediction markets is former New Jersey governor Chris Christie, who championed the PASPA case to the Supreme Court.
