I look at differently. I don't think the Trump odds are hype, it's just that the Hiden lead is overstated, and people are using other indicators. The models using the polls and what you see in reality don't tally.
Low youth turnout, huge enthusiasm gap, early voting not that good for Hiden in FL and other states, the quality of the DNC ticket is abysmal, voter registration gap between DNC and GOP at all-time lows in battlegrounds, the disparagement of non-conforming polls as 'low quality/biased', the lack of coherence in state polls, the crazy leads in the national polls, and the betting line itself. I just can't imagine big players will pass up this free money if they actually believed in the polls.
