The deal was first announced in June. It includes $240 million from the merger. It also features a credit facility that could provide up to $400 million in additional funding.

Parataxis CEO Edward Chin said this deal is a step forward in listing a company that gives strong Bitcoin access to markets that don’t have many options. He mentioned that the company will have sufficient funding to carry out its Bitcoin strategy in the United States. Once the merger with SBXD is finalized, the company also intends to grow its operations in South Korea.

He added:

“We will also be ideally positioned to further establish and grow our successful foothold in South Korea with Parataxis Korea. We are proud to have the support of SilverBox Capital, who have been excellent partners throughout this process, and we look forward to continuing to work alongside them.”

Rising Institutional Demand Fuels Bitcoin Accumulation

Joe Reece, who helped start SBXD and also helps lead SilverBox Capital, said that Ed and the Parataxis team have created a strong and easy-to-grow platform. He said it gives big investors access to a smart and modern digital asset strategy.

In the last year, more and more companies have started using Bitcoin to manage their treasuries. This growing interest shows how popular Bitcoin has become for this purpose. Based on data from BitcoinTreasuries, around 289 organizations have boosted their Bitcoin holdings by 4.3% over the past month. Their combined Bitcoin holdings have now grown to nearly 3.65 million BTC. Among all holders, MicroStrategy (NASDAQ: MSTR) owns the largest share. It currently owns about 628,791 Bitcoins, which are valued at nearly $72.4 billion.

The growing interest from companies using Bitcoin for treasury management has created a big gap between supply and demand. Market data from CoinGlass shows that the total amount of Bitcoin available on major exchanges has dropped to around 2 million coins, which is the lowest level in several years.
