Clare Bronfman, the Seagram’s heiress and accused sex-cult leader, had to cough up a staggering $100 million bond to avoid spending her nights in a federal lockup while she awaits trial.

Brooklyn Judge Nicholas Garaufis on Tuesday set the sky-high amount — secured by $50 million in personal assets — after prosecutors argued that Bronfman, 39, accused of identify theft, money laundering, extortion and other crimes to help bring recruits and money into Nxivm, has plenty of money to orchestrate her escape from prosecution.

“Bronfman is a frequent international traveler, with access to a private jet, and has an ownership stake in a private island in Fiji’s Lomaiviti Archipelago,’’ the feds told Garaufis.

But while the bond figure is stunning, it matches what rogue inside trader Raj Rajaratnam was released on in 2009 — and is a pittance of the amount that accused serial murderer and New York City real-estate scion Robert Durst got from a Texas judge in 2003.

Durst was ordered held on $3 billion, before a state appeals court later lowered the amount to $450,000.

Another Texas judge went even further, setting bail at $4 billion for an accused murderer last year, according to the Dallas Morning News.

Bronfman has until Friday to finalize her bail arrangement.

She was let out under home confinement and has to wear an electronic ankle bracelet at least until then.

She is liable for the $100 million that had to be put up by parties not affiliated with Nxivm.
