The first market had a list of wrestlers. Customers could have a punt whether their selection would win either the WWE World of Universal Championship at any point from the time the bet was struck right up to the end of next year's WrestleMania.
When the market was first installed, and as you can see in the image below, the oddsmakers had Styles as the favourite.
He opened at 1/5. Then - by June 8th - the selection had been snipped to 1/8 before moving to 1/10 in mid-July.
Another 'Road to WrestleMania 34' market that was settled today was a head-to-head special where customers could bet which wrestler would win either of the major WWE titles before the other. Styles was opposed with Braun Strowman in this matchbet.
AJ opened started off as a favourite and - despite being tied with Strowman at 11/10 when the market was republished on September 15th - was always the bookie's choice to win this.
It was difficult for Strowman to win because he is a member of the Raw roster where it seems very likely that the Raw champion, Brock Lesnar, will go through everyone before dropping the Universal Title at WrestleMania.
'Neither Win Title' was also backed in the latter stages. This was likely due to people believing that Jinder Mahal's reign would extend all the way to WrestleMania without a hiccup. Many, myself included, thought that the Modern Day Maharaja would at least still be in possession of the title for the two-night trip of India which is thirty days from today.
I'll have another look through the Road to WrestleMania 34 markets when they're republished at a later date. You can read about other markets that were settled following Styles' victory in THIS POST.
