Shares of Zhihu Inc., the Chinese question-and-answer platform, are soaring 7% in overnight trading following the release of its better-than-expected second-quarter financial results. The company's impressive performance, particularly its surprise profit, has sparked investor enthusiasm despite a decline in revenue.

Zhihu reported adjusted earnings of 29 fen per share for the quarter ended June 30, significantly outperforming the lone analyst forecast of a 26 fen per share loss. This unexpected profitability marks a notable turnaround for the company and demonstrates its ability to improve operational efficiency.

However, revenue fell 23.2% to CNY716.89 million compared to the same period last year, slightly below the analyst expectation of CNY756.17 million.
