Billionaire venture capitalist Peter Thiel has purchased over 9% of crypto mining provider BitMine, bringing his total ownership to 5.09 million shares in the firm.
The move comes after BitMine announced it now holds over $500 million worth of ETH, following the closing of its initial private placement of $250 million on July 9.
On Tuesday, according to a filing with the U.S. Securities and Exchange Commission, Thiel and his Founders Fund disclosed that they had acquired a 9.1% stake in BitMine.
The purchase follows reports in June the fund had invested in BitMine.
According to the SEC filing, the firm acquired over five million shares.
The private placement saw BitMine sell over 55 million shares at $4.50 each, with the proceeds going toward Ethereum reserves.
Kraken, Pantera Capital, and Galaxy Digital were among the other firms that also participated in June.
On Monday, BitMine announced it holds over half a billion dollars’ worth of Ether in its treasury.
The firm stated it holds over 163,000 ETH in its reserves, purchased at an average price of $3,072 per token.
The launch of BitMine’s Ethereum treasury strategy has caused BitMine’s stock price to fluctuate dramatically, ranging from lows of $4 to highs of over $130.
BitMine’s stock rose to $59 on Monday, representing a 45% increase from Friday’s price of $40.
A new wave of publicly traded companies are shifting their corporate Bitcoin strategies toward Ethereum, as firms increasingly look to take advantage of its smart-contract capabilities.
On July 7, digital asset firm Bit Digital announced a strategic move to Ethereum, stating that ETH would “rewrite the entire financial system.”
The company used funds from the sale of 280 Bitcoin, along with proceeds from a recent public offering, to acquire over 100,000 ETH.
“As of today, Bit Digital has accumulated over 100,000 ETH,” the company wrote in a statement.
“But we are not new to Ethereum, nor to our conviction in its opportunity,” they added.
SharpLink Gaming, led by Ethereum co-founder Joe Lubin, now also holds over 255,000 ETH, making it the largest corporate Ethereum treasury to date.
