Seemingly on the route to a public offering, data mining company Palantir is seeking to raise nearly $1 billion in new funding as indicated by a filing with the SEC, $550 million of the targeted amount already secured from Japanese corporations Sompo and Fujitsu. Sompo, an insurance giant, recently invested $500 million in Palantir while IT giant Fujitsu chipped in the remaining $50 million. Both Japanese corporations have partnered with Palantir to offer the company’s services in the Japanese market.

Palantir’s valuation with the new funding isn’t known but for a hint, reports emerged last September that Palantir was seeking new funding at a valuation ranging from $26 billion to $30 billion. Palantir, which was founded sixteen years ago, has raised $3.3 billion in funding since its founding according to PitchBook data. Recently, reports emerged of the company planning to confidentially file for a public offering in the “coming weeks”, and Palantir actually seems to be planning a soon public listing, having recently added three new board members, including its first female director.

Palantir’s recent SEC fundraising filing is notably the company’s first in a four-year period.
