The new markets on board are: Best Finishing Position, Ironperson and Race to the Buzzer.
Best Finishing Position
A regular fixture from Kambi during the build to the Rumble where the oddsmakers price up head-to-heads on two participants. A winning wager will be whoever outlasts the other during the battle royal.
For the men's match, they have - as of the time of writing - paired off the following wrestlers:
John Cena .vs. Shinsuke Nakamura, John Cena .vs. Roman Reigns, Seth Rollins .vs. Jason Jordan, Randy Orton .vs. Baron Corbin, Samoa Joe .vs. Finn Balor and Matt Hardy vs. Jeff Hardy.
The women's market has the following matchbets:
Asuka .vs. Ronda Rousey, Paige .vs. Asuka, Paige .vs. Nia Jax, Ruby Riott .vs. Becky Lynch, Carmella .vs. Naomi and Bayley .vs. Sasha Banks.
It's worth noting that - for any action - both wrestlers must appear in the match. For example, as of the time of writing, Paige could be sidelined. Therefore, any of the markets with her in them will be settled as void.
Update: After posting, I found out that Paige has been forced to retire due to the injury she suffered a number of weeks ago
This is another regular. In these markets, the traders are taking bets on the person who ends up lasting the longest in their respective battle royal. For example, if Roman Reigns is 4/1 to accumulate the most minutes in the male match while - over in the female market - Becky Lynch is 9/4.
Race To The Buzzer
In this market, customers have a selection of names to choose from. If this particular superstar is still in the match when when the last entrant is introduced to the match, the bookie will pau out.
The ladies market lists the following names and odds:
Nia Jax 1/5
Sasha Banks 7/20
Ruby Riott 13/20
Sonya Deville 4/6
Mickie James 7/10
Sarah Logan 17/20
Becky Lynch 3/1
Liv Morgan 3/1
Mandy Rose 3/1
For what it's worth, I have backed Becky Lynch at 3/1. If the women's Rumble match is going to be won by a representative of the Raw brand, I think some of the top females from Smackdown would have to still be hanging around near the end.
Over in the section for the male match, they have:
John Cena 1/14
Shinsuke Nakamura 1/14
Finn Balor 1/5
Samoa Joe 1/3
Baron Corbin 1/2
Bray Wyatt 1/2
Randy Orton 1/2
Matt Hardy 11/20
Aiden English 6/1
