When is the Cipher IPO Date? In March 2021, Cipher announced plans to enter the public markets via a SPAC deal. SPAC stands for Special Purpose Acquisition Company, and firms like this are often called ‘blank check companies’ since the sole purpose for existing is to purchase a private company and bring them public. SPAC deals avoid some of the regulatory headaches that most IPOs contend with, but still have their downsides. Cipher will merge with the Good Works Acquisition Company (NASDAQ: GWAC) in a deal rumored to be worth over $2 billion. Once finished, the company will be known as Cipher Mining Inc. and trade on the Nasdaq under the ticker CIFR. No formal IPO date has been announced yet, but analysts are expecting a debut sometime before the end of Q2 in 2021.
