It doesn't take much money to drastically reduce a horses odds. Until Churchill decides to actually make their Kentucky Derby future pool available earlier, and with more than 24 betting interests, Vegas odds will almost always be lower than they should be, since so few casinos offer them.
It's not a pari-mutuel pool, so they list them at whatever they want. In order to get lucky, you need to find a horse and bet him before their "big" win. West coast runners typically get pounded down a lot earlier, since so many Vegas horse players concentrate on California tracks (and since so many Californian's visit Vegas regularly).
