Brock in the Chamber

Which is more likely:

1) That Brock Lesnar is one of the first two in the Chamber and beats everyone before the next pod opens, or
2) That Brock Lesnar is the last into the Chamber and pins all five guys in less time than it would take for the next pod to open?
Well he has to lose, right?  So obviously he goes in first and then gets pinned in 30 seconds so he can maximize his payday.
