Clearly, not all markets are asking the same question, and each platform has different constraints (betting limits, where operable, etc.). Still, this seems like a large gap (6 cents vs. 13 cents).
By the way, despite differences in the early days of the Harris campaign, seemingly near-equivalent bets are registering similar odds now: 58-45 Harris over Trump, 59-44 for Democrats over Republicans for White House, 58-42 Harris is 47th President.
