It’s possible for anyone to control the media, but not bookies. They need to provide odds that reflect the real chances of the candidates; otherwise, they’d lose a lot if many people are gonna be backing Trump to win. I noticed at one point that Kamala was the favorite, but with all the huge money coming in for Trump, they had to adjust the lines, which is why Trump is now seen as the heavy favorite to win.
The bookies are not 100% reliable either. I think we can rely on the trend that has been, and that is that Kamala has made a bad campaign and Trump a very good one, so Trump will have won votes and Kamala lost but we can not know if that will be enough for Trump to win. And in the case of the bookies what they show is that there are more people betting for Trump but the profile of people betting is not representative of the whole electorate.
When the line first opened, there was a basis for it, and now that it has moved, it’s definitely based on how much money is flowing into this betting market. No one knows who will win, not even the candidates. So, in terms of reliability, I think I’d rather stick with the bookies than listen to the media. Sometimes, bookies have information that the media doesn’t report, and they consider that as one of the factors when creating the betting lines.
