The IPO market staged a quick recovery from the first quarter’s spike in volatility, as 48 IPOs raised a record-breaking $104.8 billion in the 2Q, led by SpaceX’s largest-ever deal ($75B). Even without SpaceX, the 2Q would have been the biggest quarter for IPO proceeds since 2021, driven by a steady flow of very large deals; nine other IPOs raised $1+ billion. Earlier themes remained prevalent among the quarter’s deals, namely aerospace and defense, AI infrastructure, energy, and biotech, while VC-backed tech largely remained absent. The Big Four accounting firms appeared on 34 IPOs, representing 71% of the quarter’s deal count but 98% of proceeds. With every offering requiring audited financials, there were 48 auditing engagements with 15 accounting firms, or 104 with 30 firms including SPACs.
