The U.S. venture-backed IPO market experienced a dramatic shift between 2015 and 2024, peaking in 2021 and declining in 2022 due to Federal Reserve interest-rate increases. The research uses Pearson correlations to analyze the relationship between IPO activity and four market elements including SPAC issuance, the M&A share of exits, interest rates, and stock-market volatility through a ten-year data collection period. The data indicates that IPOs increased with SPAC market activity (r ≈ +0.88) but decreased when acquisitions became the primary exit method (r = –0.96) because founders view these channels as interchangeable. The study shows interest rates have a moderate negative relationship with IPOs (r ≈ –0.54) yet equity market volatility provides minimal explanatory power (r ≈ +0.20). The research demonstrates that companies need to keep both IPO and M&A options available while regulatory clarity affects SPAC market performance. This study demonstrates exit market flexibility through its annual data analysis, yet further research using higher-frequency and cross-country data is needed.
