Peter Thiel Acquires 7.5% Stake in Ethereum Treasury ETHZilla

Peter Thiel, the billionaire tech investor and co-founder of PayPal and Palantir, is part of an investor group that holds a 7.5% stake in 180 Life Sciences, which is rebranding as ETHZilla, an Ethereum-focused corporate treasury vehicle, according to a new SEC disclosure. Shares of 180 Life Sciences (ATNF) jumped over 11% at Monday’s close and surged roughly 57% in overnight trading, Yahoo Finance data shows. 180 Life Sciences announced its Ethereum treasury plan in late July.

On Monday, the biotech firm said it sold $156 millionin senior secured convertible notes due 2028 to an institutional investor, following a recent $425 million private placement. Proceeds will primarily fund Ethereum purchases, yield-bearing assets, and the company’s iGaming operations, while monetizing legacy biotech IP. Thiel’s investor group now has stakes in two Ethereum treasury companies. In mid-July, he reported holding over 9% of Tom Lee’s BitMine Immersion, currently the biggest corporate ETH holder with close to $5 billion in its treasury.
