According to the Continental Stock Transfer and Trust web page:

“As the industry-leading SPAC administrator since 2003, Continental has handled over 95% of the SPACs brought to market over the past 19 years.  Likewise, we have handled 60% of the U. S. IPOs over the past three years. This is a testament to our proprietary platforms for handling the complex business combination/redemption stage, and for oversight of the hundreds of customer trust accounts.”

A spot check of prospectuses exhibits thereto of some of the SPACs sponsored by serial SPAC sponsors (e.g., Churchill Acquisition Corp. (acquiring SPAC of Lucid Motors)) and Social Capital Hedosophia (acquiring SPAC for Virgin Galactic), Continental Stock Transfer and Trust holds SPAC trust deposits at JPMorgan Chase.
