Goldman Sachs has over 1.3 million derivative contracts, which explains why regulators won't do anything meaningful to reign in such weapons of mass financial destruction.
Goldman's 3rd quarter 10-Q highlights general betting areas. They include:
Interest rates-- 1-5 years and 10 years or greater
Currencies-- 0-12 months and 1-5 years
Credit derivatives-- 1-5 years and 5-10 years
Equities-- 0-12 months and 1-5 years
Commodities-- 0-12 months and 1-5 years
Given Goldman's ability to make money trading 98% of the time, how might they make their financial bets come true?
