SPACs traditionally don’t have any guaranteed primary capital. 100% of their investors can redeem. So you are guaranteeing the sponsor their rake but they are not guaranteeing that you’ll get any money from the listing. Plus this article doesn’t mention the warrant coverage, which cannot be negotiated down, and IPO fees (when SPACs go public, the bankers defer their fees until the SPAC completes a transaction). I think this article researched the inefficiencies of the IPO process to the last detail, but somehow forgot to do the same on the SPAC process. Door #3 is just as rigged as door #1.
