Bitcoin investment platform Parataxis Holdings is making a move toward the public markets through a proposed merger with SilverBox Corp IV, a special purpose acquisition company (SPAC) valued at $200 million and listed on the New York Stock Exchange.
According to the announcement, the potential deal, outlined in a non-binding letter of intent signed on June 9, marks an early-stage step toward bringing Parataxis’ institutional-grade digital asset strategies to a broader investor base. Parataxis Holdings operates as an affiliate of Parataxis Capital Management, a digital asset investment firm founded in 2019.

SilverBox Corp IV is part of SilverBox Capital LLC, a firm launched in 2020 with a focus on sponsoring SPACs and offering alternative investment management services. The partnership aims to tap into the increasing demand from institutional investors for exposure to Bitcoin and other digital assets.
According to both parties, the merger would position the combined entity to deliver proprietary Bitcoin and crypto investment strategies tailored for institutions. Parataxis is targeting clients looking to adopt Bitcoin as a treasury reserve or strategic portfolio asset—a trend that has gained momentum as digital assets continue to penetrate traditional finance.
Joe Reece, co-managing partner at SilverBox Capital, described the merger as a step toward introducing a “unique and highly scalable digital asset management platform” to the public investment sphere. A notable part of the firm’s post-merger strategy includes launching a transaction in South Korea—an emerging market they believe is ripe with digital asset potential but currently underserved.
Despite the optimism, the deal remains in preliminary stages. The letter of intent includes standard disclaimers, underscoring that no definitive agreement has been signed, and the transaction may ultimately not materialize.
Clear Street, a technology-driven platform for multi-asset clearing and portfolio management, is serving as the lead financial adviser on the proposed merger.
Meanwhile, Stablecoin issuer Tether deepened its bet on Bitcoin, purchasing $458.7 million worth of the cryptocurrency on behalf of Bitcoin investment firm Twenty One Capital, which is currently navigating a SPAC merger with Cantor Equity Partners.
