In my current campaign, I've hinted to the players that the secret cabal of clever cultists are funding themselves in no small part by gambling on what is essentially the world's nascent commodity markets using divination to predict which commodities will be scarce later and in what locations and therefore in high demand.
That's very entertaining. In my campaign (which has a more 18th century social structure), most of the greatest diviners in the world work for the commodities traders.
