Billionaire Jeff Bezos on Sunday dismissed reports that he was about to spend a staggering $600 million on a star-studded Aspen wedding to his fiancée Lauren Sanchez.

The wedding news comes from an exclusive report by the Daily Mail, which quoted three anonymous sources as saying that the Amazon founder’s lavish wedding is scheduled for December 28th. The report claimed that actor Kevin Costner’s Dunbar Ranch and sushi restaurant Matsuhisa would be the venues for the ceremony and reception.

Numerous other websites picked up the story, citing the Daily Mail. One such report caught the attention of Bezos’ fellow billionaire Bill Ackman, who posted on X that the dollar figure was “not credible.”

“If you don’t buy each of your guests a house, you won’t have that much money to spend,” Ackman posted.

Bezos, who is worth an estimated $238.5 billion, responded to Ackman’s tweet and not only disputed the price but also appeared to suggest that there was no wedding planned next weekend.

“Also, the whole thing is completely false – none of this is happening,” Bezos posted on

Bezos continued, paraphrasing a quote often attributed to Mark Twain.

“Now lies can spread around the world before the truth comes out. So be careful people and don’t be gullible,” he wrote.

Bezos said it will be “interesting to see if all the media outlets that have ‘covered’ and re-reported on this issue make a correction as it comes and goes and doesn’t happen.”

Bezos, 60, and Sanchez, 55, have been engaged since May 2023. Before their engagement their relationship had taken almost five years. Both had previous marriages, with Bezos splitting from Mackenzie Scott after two decades.

According to Forbes, Bezos’s net worth makes him the second richest man in the world after Elon Musk.

He currently owns the Washington Post and the aerospace company Blue Origin.

“This is an important reminder to you as the owner of one of the country’s most important newspapers why it is so important that you take all necessary steps to ensure that your reporters are getting the facts right,” Ackman responded until Bezos shot down the wedding rumors .

According to her Instagram bio, Sanchez is a New York Times bestselling author, an Emmy-winning journalist, and vice president of the Bezos Earth Fund.
