For more than a year, the payments processor founded by billionaire brothers Patrick and John Collison has been teasing an IPO to rev up growth with fresh public market cash. And though John told CNBC in August that Stripe is “very happy as a private company,” the PayPal competitor was reportedly talking to investment banks in September about a market debut this year that could push the fintech firm past a $100 billion valuation. If founders decide to take the plunge, Stripe would easily become one of the largest IPOs to hit the market.

TPG

Assets Under Management: $109 billion as of December

Late last month, the private equity powerhouse founded by billionaires James Coulter and David Bonderman announced plans to list on the Nasdaq exchange. Though it’s keeping many details under wraps, the firm listed an offering size of $100 million, but suggested that could likely increase depending on investor interest. The company, which is reportedly eyeing a public valuation of $10 billion, holds outsize stakes in talent agency CAA, Vice Media and Spotify. Its debut would breathe new life into private equity public listings after a massive boom in buyout deals.

Trump Media

Latest Valuation: $2 billion market capitalization as of January

Former President Donald Trump dazzled investors after announcing plans in October to take his social media company public via SPAC. Shares of the vehicle, Digital World Acquisition Corp., skyrocketed more than 1,700% as retail investors plowed into the stock late last year—helping it briefly eclipse a market capitalization of $10 billion, compared to an expected valuation of $875 million—before tumbling 70% once the fervor cooled off. The firm, which was founded in February and has yet to release a working product, has since revealed plans to cash in on the retail frenzy by raising about $1 billion from investors. However, regulators are already pouncing on the move, with the SEC initiating an investigation into stock trading and high-level communications last month. No one’s been accused of wrongdoing, but it’s unclear how this will affect Trump’s latest moneymaking venture.
