The Bitcoin miner turned AI infrastructure play is going public after closing a $400 million private placement at a $2 billion valuation
Ionic Digital, the company born from the ashes of Celsius Mining’s bankruptcy, has filed a public S-1 registration statement with the SEC for a direct listing on the Nasdaq Global Select Market. The company plans to trade under the ticker IOND.
The filing, submitted on June 29, 2026, comes just three days after Ionic closed a $400 million equity private placement that valued the firm at $2 billion pre-money.
From bankruptcy acquisition to billion-dollar listing #
Ionic Digital was established specifically to acquire the mining assets of Celsius Mining during the Celsius Network bankruptcy process. That bankruptcy plan was confirmed on November 9, 2023, and became effective on January 31, 2024.
The haul was substantial: approximately 127,000 Bitcoin mining units and associated power infrastructure across US facilities. The company currently operates more than 110,000 active Bitcoin miners.
A confidential draft S-1 was submitted back in late October 2025, giving the company roughly eight months of preparation before going public with its filing.
The AI pivot that Wall Street loves #
Ionic Digital has been repositioning itself as a builder of energy-intensive digital infrastructure designed to support artificial intelligence and high-performance computing workloads, while continuing Bitcoin mining operations across its US facilities.
Direct listing mechanics and what they signal #
Ionic Digital chose a direct listing rather than a traditional IPO. In a direct listing, existing shareholders sell their stock directly to the public without the company issuing new shares. There are no underwriters setting an initial price, no roadshow, and no lockup periods for insiders.
The practical effect: Ionic won’t raise additional capital through the listing itself. That’s why the $400 million private placement matters so much. The company essentially raised its growth capital privately, then plans to use the direct listing purely to give those shares liquidity on a public exchange.
The filing notes that the listing remains subject to SEC review and market conditions. The Class A common stock structure will be listed on the Nasdaq Global Select Market under the ticker IOND.
What this means for investors #
The Celsius bankruptcy origin is both an advantage and a risk factor. On the plus side, Ionic likely acquired its assets at a discount to replacement cost, giving it a lower cost basis than competitors who built or bought infrastructure at market prices. On the risk side, bankruptcy-acquired assets sometimes come with deferred maintenance, contractual complications, or operational inefficiencies that take time and capital to resolve.
The $400 million in fresh capital gives Ionic meaningful runway, but converting power infrastructure from crypto mining to AI workloads requires significant additional investment in cooling, networking, and GPU procurement that the S-1 should detail.
