Rocket maker Ursa Major Technologies is set to go public via a SPAC merger, valuing the hypersonic missile developer at $2.3 billion. This move contributes to a record-breaking U.S. IPO market, following SpaceX’s massive offering and ahead of potential listings by AI giants Anthropic and OpenAI. Meanwhile, infrastructure firms like Switch and SB Energy are preparing for debuts, and Hyundai Mobis is gaining valuation from its expanding robot actuator business.
