Prediction markets continued to move toward mainstream financial infrastructure this week, even as the legal battle over who has the right to regulate them intensifies.
The CFTC and several US states escalated their fight over event contracts, Cboe introduced a regulated binary options product with familiar predictive market returns, and Polymarket expanded its soccer portfolio with the Bundesliga.
Here’s what matters this week.
The state’s battle escalates
The legal battle over prediction markets expanded again this week, with new lawsuits filed on both sides. Kentucky has filed a lawsuit against Calci and PolyMarket, accusing the platforms of operating sportsbooks that are illegal under state law.
Meanwhile, Calci has asked a federal court to block the state of Illinois from imposing a new licensing and tax system that the company says conflicts with the Commodity Exchange Act.
The dispute quickly expanded beyond the platforms. In response to Kentucky’s enforcement actions, the CFTC filed its own lawsuit against the state, arguing that Kentucky is attempting to interfere with federally regulated exchanges and undermine the agency’s exclusive jurisdiction over event contracts.

These cases are part of a broader campaign that now includes multiple states, including Illinois, Minnesota, Rhode Island, Arizona, Connecticut, New York and Wisconsin. The question before the courts remains the same: Where does state gambling law end, and where does federal derivatives regulation begin?
The legal battle is unfolding alongside the CFTC’s formal rulemaking process. The agency this week opened a public consultation on the proposed prediction markets framework, describing it as a transparent process to determine which event contracts are in the public interest and which should be banned. The proposal will remain open for public comment for 90 days.
today, @Koftak Proposes new data reporting regulations for fully collateralized event contracts.
For too long, market participants have relied on a patchwork of swap statements signaling no-action rhetoric. Under my leadership, the agency is working to establish clear regulations… https://t.co/9a7ja9rkEO

Cboe brings prediction markets to Wall Street
Cboe is launched Cboe predictsand the introduction of binary options on the Mini S&P 500 through a regulated US stock market. Contracts allow traders to take a simple yes or no position on where the index will close, using a return structure that is very similar to prediction markets.
Unlike event contracts on platforms like everythingHowever, they are listed as securities, are cleared by an options clearing corporation, and are traded under the current options framework. Interactive Brokers already offers contracts with Charles Schwab This is expected to follow in the coming months.
The launch represents another avenue through which prediction-style products will reach key investors. Rather than competing directly with event contract platforms, Cboe brings a similar trading format to a regulated ecosystem of exchanges and brokerages.
Polymarket signs an agreement with the German Bundesliga
It has become a polymarket Official prediction market partner of the Bundesliga In the United States, securing exclusive market launch rights to the German Football League ahead of the 2026–27 season.
However, there is one key piece that remains unresolved. while Polymarket Sportradar has acquired the branding rights to the league, but the official match data needed to operate those markets is controlled by Sportradar under a separate agreement that has not yet been announced.
This distinction is important because official data determines how quickly markets can update, settle, and expand beyond simple contract wins. Polymarket already has a similar arrangement in place in Serie A through Genius Sports, however German League The partnership is not yet fully operational.
The deal shows that predictive market partnerships are increasingly reliant on more than just sponsorship rights. As the industry has matured, access to official data has become as important as access to the journals themselves.
Week number
Calci is reportedly in talks to raise new financing at a price Rating around 40 billion dollarsaccording to the Financial Times. That would nearly double the $22 billion valuation from its $1 billion round last month. Less than a year ago, Kalshi’s value was about $5 billion.
Bottom line
American courts are full Prediction market Lawsuits, but the industry is not waiting for legal clarity. The CFTC and several states are fighting over where federal derivatives regulation ends and state gambling law begins.
At the same time, Cboe is launching prediction-style products within the established securities framework, and Polymarket is signing league partnerships that rely on official sports data.
The result is a market that develops along two tracks simultaneously: legal uncertainty on the one hand, and product launches and commercial partnerships on the other.
