However, there are still days for any potential investors to make paper applications, with the final deadline on Friday, April 29.
It is the fourth round of crowdfunding, named Equity for Punks, for the brewer and pub retailer, which is also planning expansion in the US.
The financing campaign called Equity for Punks IV raised more than £5M in the first 20 days and Brewdog now has 42,000 investors in the business.
US expansion
The next round Equity for Punks USA is set to launch in the Summer of 2016.
Speaking on its blog, Brewdog said: “The incredible success of Equity for Punks IV is a testament to our continued drive to make other people as passionate about great craft beer as we are.
“The record-breaking public response to each of our shareholding offers has been nothing short of incredible, and from the moment the stuffed cats rained down on the fat cats in the City of London back in May 2015, that reaction has only continued.”
Donald Trump
At the end of last year, the brewer offered US presidential candidate Donald Trump shares in the company to quit politics.
Brewdog’s co-founder James Watt, in a pithy letter, offered the controversial US politician two Equity for Punk shares as a Christmas present.
He said he hoped the shares would “spark a desire in you to get back into business, locking yourself in your office as necessary”.
He also informed Trump that the UK is the “one on right-hand side of the Atlantic, where we all have tea with the Queen”.
