SAO PAULO, Jan 28 (Reuters) - Brazilian digital bank PicPay is expected to price its U.S. initial public offering (IPO) on Wednesday at the top of the indicated price range of $16 to $19 per share, a source familiar with the matter said.

Demand for the transaction, which marks the return of Brazilian issuers to New York after a four-year drought, has already exceeded $4.5 billion, or roughly ten times the amount the company aims to raise, the source added.

The oversubscribed IPO would give the company, backed by the billionaire Batista family, a market valuation of $2.2 billion to $2.6 billion, according to the source.

Newspaper Valor Economico first reported the information earlier on Wednesday.

PicPay did not immediately respond to a request for comment.

One of Brazil's largest digital banks, PicPay had previously pursued a U.S. listing in 2021 but dropped that plan due to market headwinds.
