PANews reported on May 21 that, according to The Block, SpaceX holds 18,712 bitcoins, according to its S-1 filing with the U.S. Securities and Exchange Commission in preparation for its IPO. The filing shows that as of December 31, the purchase cost of these bitcoins was $661 million, equivalent to approximately $35,000 per bitcoin. SpaceX began purchasing bitcoins in 2021, almost simultaneously with Tesla's well-known $1.5 billion investment in bitcoins that year. Since then, the company has reduced its holdings; according to an Arkham report, its holdings once fell to 6,095 BTC last year. On Wednesday, Arkham data showed that SpaceX held approximately 8,280 BTC. If SpaceX's holdings exceed 18,000 bitcoins, it will become the seventh largest bitcoin holder, ahead of Coinbase. At the current bitcoin price, these holdings are worth over $1.45 billion.
