It's fair to say that investor demand for long-awaited IPOs is back. Online banking company Chime (NASDAQ: CHYM) finally went public after years of stagnation in the fintech IPO pipeline, and to call it a successful public debut would be a bit of an understatement.

Chime Financial Inc. jumped as much as 66% in its trading debut after raising $864 million in an initial public offering priced above the marketed range.

Chime opened on Nasdaq at $43 a share on Thursday, 59 per cent above its $27 IPO price, to give the group a fully diluted market capitalisation of about $17bn. The shares edged down to $40 in early-afternoon trade. About 32mn shares were sold, raising $864mn for the company.
