Well, the rumors have finally been proven true. On Friday, littered across every financial news publication and all over financial television it was confirmed that Snap, Inc. (SNAP  ), the makers of the popular app SnapChat would be going public. The company will be looking, as of now to raise $3 billion and, according to their filing, sees themselves with a valuation of $25 billion. No pricing terms have been reported yet but investors did get a better look into the financials of the company. Last year the company saw a huge jump in their number of users, but still lost $515 million. Even so this will still be the most focused on IPO since the Facebook (FB  ) days.

This week we have a few interesting IPO's scheduled to launch, all with sizable offerings. There is a building products and a packaging company along with a real estate firm focused on properties specifically in New York city.

Mauser Group (MSR  ) is a large, industrial packaging company that leads their industry in almost every product category they offer. They are looking to raise $265 million by offering 12.6 million shares at a range of $20-$22 to pay down some of its debt.

Foundation Building Materials (FBM  ) bills themselves as a leading North American distributor of building products. Based out of Tustin, Califorina, they are coming to the IPO markets looking for $230 million, offering 12.8 million shares at a range of $17-$19.

Clipper Realty (CLPR  ) is a real estate investment trust that currently has a portfolio of six properties in Manhattan and Brooklyn. They will come to the IPO markets this week in hopes of raising $103 million "to purchase the 107 Columbia Heights building in Brooklyn and for improvements to its existing holdings." Their offering will be 7 million shares at a range of $13.50-$15.50.
