Mobile payments company Square has confidentially filed for an initial public offering, according to a Bloomberg report.
The IPO will be led by Goldman Sachs, sources told CNBC.
Founded by Jack Dorsey, who is also Twitter's interim CEO, Square has ventured into new areas including small-business financing and payroll solutions.
The company's new Square Capital business has advanced more than $100 million in capital to independent businesses since launching last year, Square disclosed in May.
In May, Square, which processed more than $30 billion in payments last year, announced a funding round from Victory Park Capital for Square Capital but did not disclose the amount.
Colleen Murray, spokesperson for Square, declined to comment on any IPO plans.
