Snapchat's parent company, Snap Inc, has filed confidentially for its IPO, according to Reuters.
The widely popular messaging app is looking to raise $4 billion at a valuation between $25 billion to $35 billion, Bloomberg reported in October.
It's not clear when Snapchat will publicly unveil the news or when it will begin trading. Snapchat declined to comment.
Snapchat was valued at nearly $18 billion in its latest round of funding in May. In October, the Wall Street Journal reported Snapchat could start selling shares as early as late March with a valuation of $25 billion or more.
