Is Wikileaks about to go nuclear?

Hillary Clinton is a huge favourite to win the election. So much so that a betting site paid out bets on her to win today.
They might have picked the top.
If Donald Trump has an ace up his sleeve, it might be Julian Assange. Wikileaks released Part 11 of the Podesta emails today and they aren't even one-third done. Assange has promised that the worst revelations will come at the end of the campaign.
But he might not get a chance to reveal them. His internet at the Ecuadorian Embassy was cut off on the weekend and there are constant rumors that he could be arrested.
Some kind of campaign to discredit or smear him may be underway as well. Yesterday, there was a report by an anoymous author that an 8-year-old was "sexually molested online" by Assange in September.
It's clear that someone doesn't want him talking. If that's the case, what does he have?
The difficulty in silencing him is that he has reputedly put in place a number of fail safes and safeguards to make sure his leaks (and perhaps more damaging ones) are released if something happens to him.
The trade
What if he has something that's devastating to Hillary Clinton? Or blatantly illegal?
The standard election trade is to sell the Mexican peso. Others include selling CAD and general risk aversion.
A further trade might be the risk of leaks in other industries. Banks in particular are vulnerable. He's often said he has the information to take down a major bank or two. Part of that may have crumbled when one of his former aides betrayed him and was rumored to have been given a huge payout by Bank of America to destroy the file.
