An initial public offering (IPO) for Liftoff, an adtech firm, is reportedly moving forward, with the company's valuation estimated at around $3.8 billion. However, there is some uncertainty as to whether the IPO is for Liftoff or another company, as some reports mention SpaceX, a separate entity, in relation to an IPO. The valuation estimates also vary slightly, with some outlets reporting $3.7 billion or mentioning unrelated financial figures.
