US-based social networking site Reddit has filed for an initial public offering (IPO) to raise as much as $200 million, Reuters reported. “We’re aiming to go public at a price of up to $500 million,” Reddit Founder Alexis Ohanian wrote in a letter. Reddit, which was founded in 1998, was valued at about $500 million in its last IPO in March this year.
