Public filings understate enforcement. The largest private transaction recorded is the $300M funding round raised by Kalshi. This tracker covers 16 actions reported across 5 publishers per the Octans Research market feed, omitting offshore venues and informal regulatory inquiries, which means the documented record misses the full scope of global enforcement actions and headline values rarely capture the complete regulatory burden.
