I'll start with the most likely betting websites.
5Dimes
The 5Dimes Sportsbook is the front runner when it comes to gambling on World Wrestling Entertainment matches. The odds are often posted a number of days before the PPV and they are always up before any of the other companies on this list.
Wrestling odds are found under 'Other Sports' of the betting board at 5Dimes.com or 5Dimes.eu.
Paddy Power
Paddy Power consistently publishes odds for each monthly World Wrestling Entertainment pay-per-view and often does it before any of the other betting companies from this part of the world.
Like the sportsbook above - Paddy Power first posted Royal Rumble 2014 betting markets on the midweek before the event.
When the prices are up, they will be found under 'Sports Novelties' in the sports betting section of PaddyPower.com.
If you are reading his post on the week of the PPV, an easier way to access the site is by following a direct link to Paddy Power's WWE Betting Page.
Sky Bet
The people at Sky Bet also post odds for each monthly WWE event.
The odds for these shows usually appear later in the week (Thursday/Friday). The website offers wagering on all matches on the card and often keep the odds up until right before the start of each event.
WWE betting is found under 'Wrestling' on the left menu of SkyBet.com
YouWin
YouWin has offered wagering on the past three WWE pay-per-views and I expect them to continue especially now that we are in WrestleMania season.
The company usually posts the odds just before the weekend hits.
WWE odds are found under 'Specials' at YouWin.com
UWin
UWin is the Canadian-facing partner of YouWin catering to fans based in Canada.
Everything that is written about YouWin applies here. Odds show up just before the weekend and can be found in the 'Specials' section of UWin.com
William Hill
When William Hill posted odds for the Royal Rumble, it was the first time they had covered a WWE event since Survivor Series.
William Hill is one of Britain's most popular bookmakers and is the first to have introduced WWE novelty betting in the early 2000's.
The company does tend to take the odds down for re-adjustment overnight so it's best to keep an eye out for them on weeks of pay-per-views. When they are available, prices can be found under 'TV / Specials' of the sports betting section of WilliamHill.com
BetFred
BetFred is one of the companies I had contacted late last year enquiring whether they would be interested in offering customers the chance to wager on World Wrestling Entertainment matches. The company took the suggestion head on and offered Royal Rumble markets.
If the firm continues offering WWE wagering with the Elimination Chamber, expect to find the odds under 'TV Show' of the sports betting menu on the Betfred Website.
Coral
Coral Bookmakers promote WWE betting for the major pay-per-views like WrestleMania, SummerSlam and the most recent Royal Rumble.
If Coral does decide to offer markets for the Elimination Chamber event, they'll be found under 'TV Specials' in the 'Non-sports A-Z' section of the sportsbook at Coral.co.uk
Another two companies that had Royal Rumble betting markets up were BoyleSports and SportingBet
