Kalshi is an up-and-coming legal US prediction market regulated by the CFTC.

The markets on Kalshi each have a betting limit which may be found within a PDF sent to the CFTC by KalshiEX LLC.

Unfortunately these PDFs are formatted differently (some even have the limit as an image rather than text). To make discovering betting limits even more tedious, there’s 702 of these PDFs (all linked on this page). As the second-highest user on the Kalshi leaderboard (of course there’s a leaderboard…) I needed to know all of these limits.

I used Claude‘s PDF beta API to extract all information from the PDFs and include it here. All coding work took me a total of fifteen minutes from scraping->extraction->summarization->this blog post.

You can sort and search the below list if for any reason you need to know the per-market contract limits on Kalshi. Most markets have a limit of $25K USD, although some larger markets have limits of $7M or $50M. Hopefully the CFTC allows these to be increased in the future!
