US IPO Weekly Recap: SpaceX confidentially files, energy play goes public, and more defense tech joins the IPO pipeline

April 2, 2026
Weekly Recap

One IPO priced this past week, joined by one SPAC, and one major deal joined the pipeline.

The biggest news of the week came from the backlog, though: Elon Musk’s SpaceX has reportedly submitted a confidential filing ahead of its mammoth IPO. Reports from the prior week indicated that the offering could raise $75 billion.

HMH Holding (HMH) priced slightly below the midpoint to raise $210 million at an $880 million market cap. HMH provides equipment and services for the oil and gas industry, with a focus on offshore operations. The company has a presence in 16 countries and sales in over 60 countries, and emphasizes a more asset-light business model compared to its peers. The energy industry is cyclical, though, and HMH partly depends on new builds and equipment wear and tear. Despite launching alongside surging energy prices, HMH broke issue on its first day; it finished the week down 6%.
