Miranda Kerr may be catapulted into the world’s richest young set, as Snapchat readies for a float that could be worth as much as $US25 billion ($A33 billion).

Snapchat has confidentially filed for its IPO, with some analysts saying the company could be worth anywhere from $US20 billion and $US25 billion ($A26.7 billion and $33 billion), according to reports.

The float has the potential to make co-founder Evan Spiegel and wife-to-be, Australian model Miranda Kerr, among the world’s richest young people.

The Wall Street Journal reported that the offering could net the couple as much as $US3.9 billion ($A5.2 billion), assuming the company lists at the top end of the valuation range.

Kerr, 33, became engaged to Spiegel, 27, in July, announcing their union on Snapchat.

The company could go public as early as March, Reuters reported, citing multiple sources.

The Wall Street Journal reported separately that owner, Snap Inc., had filed to go public before the election last week, but that the outcome of the election didn’t affect the company’s plans.

A Snapchat spokesperson declined to comment.

Snap would be just the latest company to take advantage of the ability to tell the securities and Exchange Commission of its intend to go public without a public S-1 filing.

These so-called confidential filings are reserved to companies with an annual revenue of less than $US1 billion ($A1.3 billion), which are also being called emerging-growth companies.

Snapchat aims to have more than $US1 billion ($A1.3 billion) in revenue in 2017; earlier this year, Recode reported that the company aimed for a revenue target of $US300 to $US350 million for 2016 ($A390 million to $A468 million).

Snap is expected to be valued between $US20 billion and $US25 billion ($A26 billion and $A33.5 billion) when it goes public, according to the Journal.

The company has raised at least $US2.63 billion ($A3.52 billion) in funding from investors including Alibaba, Benchmark, Kleiner Perkins Caufield and Byers and others.

News of the filing comes just days after Snap launched its first hardware product with Spectacles, a set of sunglasses capable of recording short video clips for sharing on Snapchat.

The company also officially announced its name change from Snapchat Inc to Snap Inc when it first revealed Spectacles in September.

Just last month, news broke that CapitalG, the investment arm of Google parent Alphabet, also contributed to one of the funding rounds.
