User-generated game platform Roblox has seen its users go through the roof in recent years, and the company is reportedly planning to go public early next year at a valuation that could hit $8 billion, according to a report in CNBC. CNBC said Roblox is working with investment banks to prepare for going public on the U.S. stock market. The company most recently raised $150 million in venture funding from Andreessen Horowitz in a deal announced in February. Roblox declined to comment on the CNBC report. But one source we contacted confirmed they believe the report is accurate.
