The group is aiming to raise up to $50m by selling over 1m shares worth $47.50 each.
BrewDog – which began in a shed in East Scotland in 2007 - has been supplying beers to the USA since 2008 but has struggled to keep up with growing demand.
The brand is currently constructing a 42-acre craft brewery in Columbus, Ohio, which is expected to be fully operational by 2017.
“What started as two humans and one dog has grown in to a thriving small business that employs over 600 talented people, ships beer to over 55 countries and has over 40 craft beer bars around the world,” BrewDog CEO James Watt said in a statement.
“With your help we can continue expanding BrewDog as we continue our mission to make other people as passionate about great craft beer as we are.”
The company has launched its campaign on American crowdfunding site Bankroll as well as its official website.
BrewDog raised £19m through its UK crowdfunding drive Equity for Punks, which ended its fourth round in April this year.
Over 42,000 people invested in the brewer, which is planning to use the funding to build a craft beer-themed hotel in Aberdeen called The Kennel, and expand its 28-strong UK bar estate.
