It's all so sketchy. Jane Street were investors in SA but presumably were much more sophisticated and savvy than Leopold. When SA got in trouble, 3 firms got into a bid war for the assets at fire sale prices: Citadel, Jane Street and a third I forgot. Citadel outbid the other 2, but it's all weird, like Jane Street wanted in on the popular boy's book that they knew was going to tank and just were waiting around in the water like sharks.
