SumUp Eyes Rare $15 Billion IPO as London Listing Drought Ends

- Fintech firm SumUp reportedly planning IPO valued at $10–$15 billion. - Move could end London’s three-year listing drought and boost market. On September 15, 2025, reports from Cryptopolitan, PYMNTS.com, and Investment Week indicated that British fintech company SumUp is preparing for an initial public offering (IPO). The IPO could value the firm between $10 billion and $15 billion. If successful, SumUp may list on either the London Stock Exchange (LSE) or the New York Stock Exchange (NYSE), a move that marks a potentially transformative moment for the LSE, as it has seen few major public listings over the past three years. SumUp plans to use the IPO proceeds to acquire rival payment firms across Europe in a strategy aimed at consolidating its position in the fragmented European payments market. Founded in 2012, the company serves over four million small and medium-sized businesses in 36 countries by providing them with mobile card readers, business accounts, invoicing tools, and other payment solutions. A decision to list in London would be a symbolic victory for the exchange, which has struggled in recent years to attract high-growth tech firms. Consequently, a successful SumUp IPO could reinvigorate its appeal to technology and fintech companies, especially since many British firms have sought US listings for higher valuations, leaving the London market stagnant. SumUp is reportedly in discussions with investment banks to finalize the public flotation within the next year, and its founders expect to remain the company's largest shareholders following the IPO.
