Thiel's holding of 100 million Palantir shares makes up about half his US$19.1 billion fortune, according to the Bloomberg Billionaires Index, which deducts the pledged stock from his net worth calculation. He also holds positions in venture fund Founders Fund and previously served on the board of Meta Platforms Inc before resigning in 2022. Thiel recently joined the board of enriched uranium startup General Matter.
Palantir Technologies Inc co-founder Peter Thiel has pledged more than US$1 billion ($1.31 billion) worth of stock he holds in the data-analysis software company as collateral for personal debt agreements, according to a recent filing.
Thiel's pledge of roughly 10.6 million shares represents more than a tenth of his stake in the Denver-based company and is valued at about US$1.2 billion, based on Monday's closing price.
