In a bid to get his space venture Blue Origin off the ground, Amazon CEO Jeff Bezos has reportedly unloaded $1.8 billion worth of Amazon stock.

On Wednesday, he sold roughly 960,000 shares, according to the company’s regulatory filing, to fund the project. Despite the dump, he remains the richest man in the world.  He’s worth $117 billion.

It is believed Bezos sells that much a year to fund the space company with lofty plans. Earlier this year, the company unveiled a new rocket engine and mockup lunar lander to shuttle cargo.

Bezos has said that he wants to build self-containing colonies one day.
