They definitely dipped at PredictIt on the last day but not that low. (According to the chart, Trump traded between 22-27% before election day). 
  
 British bookmakers still had it around 30%.

I'm not sure where I saw it but it definitely dipped under 10% within the last week before the election. I remember because 10% had been my threshold for going long Trump but then I pussied out at the last minute.
