The document library
The documents behind the prediction market fight
The court opinions, injunction orders, cease-and-desist letters, Supreme Court petitions and CFTC orders that decide where Kalshi, Polymarket and the rest can operate. We read each one in full, summarize it in plain English and link the copy posted by the court or agency that issued it.

How we build the library
We read the document
Every summary is written from the document itself, not from news coverage of it. Each page shows the date we read it.
We link the issuer's copy
We link the copy posted by the court, agency or the federal courts' filing system first. When the issuer hasn't posted it, we link a faithful copy and say whose it is.
We keep it current
New rulings and letters are added in the weekly update, and each case and state timeline links to the documents behind it.
Have a filing or letter we're missing? Send it to contact@predictionmarketlaws.com. Reporters and lawyers can find citation formats, downloads and embeds on the page for reporters and lawyers.
Download the library as CSV or JSON, or follow new additions by RSS. Free to use with a link back to predictionmarketlaws.com.
