Tuesday, May 26, 2026 was one of the most active IPO days of the year. At least nine companies announced IPO terms or filed updated S-1s, spanning quantum computing, aerospace & defense, silver mining, insurance, natural gas royalties, and SPACs.
The wave was led by Quantinuum (QNT), the Honeywell carve-out developing quantum computing systems for enterprise and government applications, which set terms for a $1.0 billion IPO at a $12.2 billion market cap. The Broomfield, CO-based company posted $36 million in trailing revenue and will list on Nasdaq. J.P. Morgan, Morgan Stanley, Jefferies, and eight other banks are on the syndicate.
Applied Aerospace & Defense (AADX) set terms for a $634 million IPO at a $3.3 billion valuation.

Revenue: $522 million. NYSE listing.
Sunshine Silver Mining & Refining (SSMR) targets $300 million at a $2.3 billion market cap for its Idaho-based Sunshine Mine, a historic silver producer slated to restart operations in 2028. Currently in care-and-maintenance mode with zero revenue. NYSE listing.

The Broader IPO Context
The last two weeks have been extraordinary. Cerebras completed the largest AI IPO ever at $5.6 billion, surging 68% on its first day. SpaceX filed confidential papers for what could be the largest IPO in history. Geothermal developer Fervo Energy priced a $1.8 billion IPO above its revised range. Investment bank Lincoln International (LCLN) raised $421 million and finished its first week up 20%. Seven SPACs also priced in the same week.
Bottom Line
May 26 marks an unprecedented accumulation of IPO activity — nine companies in a single day signals a red-hot primary market spanning mega-tech, energy, mining, insurance, and SPACs. The real test comes the week of June 1, when most of these offerings are expected to price. All eyes will be on Quantinuum, Applied Aerospace, and Sunshine Silver — three very different companies testing the market's depth simultaneously.
