The Venice, CA-based company plans to raise $3.0 billion by offering 200 million shares (28% insider) at a price range of $14 to $16.
The range of the valuation is on the low end of Snap's initial estimates, which were in the $20 billion to $25 billion range.
The much-anticipated deal would be the largest US tech IPO since Alibaba went public in 2014, and it would make Snap the largest USA tech company to go public since Facebook in 2012, according to Renaissance Capital.
The class A stock being sold doesn't contain any voting rights, making Snap the first U.S. IPO to issue non-voting shares.
The company will list on the New York Stock Exchange under the ticker symbol SNAP. Today, Twitter shares trade at less than $17. Snap's earliest investor, Lightspeed Venture Partners, could make as much as $74 million.
The Snap Inc. IPO is expected to be the largest tech offering in several years and could leave Snap flush enough with cash to quickly ramp up its platform through a combination of acquisitions and organic growth.

The founders will maintain tight control over Snap's stock through a unique three-share class structure. It generates the majority of its revenue from advertising, seeking to challenge the dominance of existing internet giants.
