The main factors were Nate Silver’s record of good calibration, and (alleged) “smart money” successful bettors (including local Zvi) being onto it. I’m still uncertain why the market could be so inefficient in this case, so I’m not betting a lot of money, but it’s possible that institutional factors prevent large amounts of smart capital coming in—perhaps directly betting on the election is still too weird for a large investment firm.
