"Geopolitical tensions, AI-scare trade selloffs, and tariff uncertainty drove higher volatility in the first quarter, tempering overall IPO activity. Despite these headwinds, the market showed pockets of resilience, with 22 sizeable IPOs raising $100 million or more and approximately $10 billion in total proceeds. SPAC issuance accelerated in the first quarter, accounting for the majority of IPOs by count. Despite this momentum, DeSPAC activity remained limited, reflecting a mismatch between new issuance and capital deployment that may influence SPAC activity in 2026."
