Monzo, the UK-based banking app valued at £4 billion, is debating whether to go public in the US or UK, with CEO TS Anil leaning toward the US, citing market advantages like liquidity. Monzo recently posted its first annual profit, moving from a £116.3m loss to a £15.4m profit, and doubling gross revenues to £880m. The fintech’s customer base and deposits have grown significantly, with its deposit base hitting £11.2bn. Monzo’s board remains divided on listing location, reflecting broader trends of UK companies favoring US markets for IPOs due to London’s declining market appeal.
