He's Building A Space Station For $1 Billion - EP 38 Jed McCaleb

15 Oct 2025

Description

Jed McCaleb grew up in Arkansas where he lived in a cabin in the woods that had no electricity or running water. Now, he’s a billionaire building a space station and funding some of the world’s most adventurous science.America remains a thing, I guess.McCaleb, 50, has been at the center of several major technology movements. Back in the peer-to-peer glory days, he released the eDonkey application for music and file-swapping and had the pleasure of being sued by the major record labels. Then, in 2010, he launched the Mt. Gox bitcoin exchange, which dominated the crypto world until it turned into a story of mega woe.A couple of years later, McCaleb developed the Ripple protocol before moving on to build yet more crypto innovations. This work made McCaleb fabulously well-to-do. (He’s worth $3 billion . . . if you believe Forbes.)McCaleb has used his fortune to back a number of start-ups and philanthropic endeavors. When Elon Musk pulled out of supporting OpenAI, McCaleb helped backfill the financial vacuum. He’s also been a major investor in Max Hodak’s Science Corp., which is developing brain computer interface technology and in the rocket maker Firefly Aerospace.McCaleb’s real blockbuster investment is Vast Space. The start-up is building a commercial space station designed to be the successor to the International Space Station, which is very much on its last legs. McCaleb says he’s prepared to put $1 billion of his fortune into Vast to make sure it happens.My conversation with McCaleb travels across these various tech eras. He comes off, at least to me, as an oddly down-to-Earth guy for someone who invests in such a variety of wild ideas.Enjoy!The Core Memory podcast is sponsored by Brex, the intelligent finance platform.
