This seems pretty speculative and a huge risk for Citadel as an institution.

I think most of their profit is coming from volume as a market maker. They capture small dollars on the bid/ask spread.

Will be interesting to see the fallout if the SEC digs in more. But I would take this with a grain of salt.

Citadel also runs an active hedge fund.
