if we just add up the Buffett, Gates, Bloomberg and Soros fortunes, the number is awfully large though. it's about $225 billion. and you end up thinking "if Trump had equal support from the wealthiest billionaires, who are they? i can't seem to find them."
Clinton was a candidate with a long track record, Trump is essentially unpredictable. The billionaire vote in this election isn't particularly surprising, or indicative that they form a Sekrit Global Cabal.
Indeed, it's more worthwhile to consider prior times that sort of anti cabal rhetoric has been deployed.
Anyway, what's surprising is not that the majority of the wealthiest billionaires supported Clinton. What's surprising is that the majority of the wealthiest billionaires supported a candidate who went on to lose the election.
It might be viewed as a battle of the major billionaires against the minor billionaires -- and the major billionaires lost. In any event, the vast majority of the wealth was on Clinton's side or at least critical of Trump.
