The digital bank has grown quickly in the UK but has made no secret of its plans to expand abroad.
UK digital bank Monzo is launching in the US, according to reports from Reuters.
The firm hit 2 million current account customers, last month, just two years since getting a banking license, and just eight months after it hit 1 million accounts.
The digital bank is seeing 35,000 new people in the UK sign up each week, making Monzo the fastest-growing bank in the UK.
A spokesman for Monzo told AltFi that more than two-thirds of its last million customer sign-ups, which occurred within just eight months, came from outside of London.
