Jacob Fischler at BuzzFeed reports that in the autumn of 2012, a single (unknown) millionaire staked, and lost, “at least $4 million” on Mitt Romney trouncing Barack Obama on November 6. Fischler cites a working paper by Microsoft’s David Rothschild and Columbia’s Rajiv Sethi, who studied trading patterns on the now-illegal InTrade.com, which allowed armchair speculators to bet on almost anything.

So: Which rich person had a few million to throw around and cared a lot about Mitt Romney winning? Speculate below!
