SEOUL -- When Kakao Bank opened its digital doors in 2017, few expected that South Korea's first online lender would stand shoulder to shoulder with the country's traditional financial giants in just four years.
But the subsidiary of the country's second-largest internet company Kakao filed an initial public offering with the financial regulator on June 28, seeking to raise up to 2.6 trillion won ($2.3 billion) on the benchmark Kospi stock market in August.
