Seoul shares opened higher Monday on gains made by technology companies ahead of the release of major companies' second-quarter earnings results.

The benchmark Korea Composite Stock Price Index (KOSPI) rose 198.39 points, or 2.45 percent, to 8,286.73 as of 9:20 a.m.

While weighing whether the artificial intelligence (AI)-driven rally can be sustained, investors are now eyeing corporate earnings results for signs that massive spending on AI infrastructure is resulting in profits.

In Seoul, tech stocks were lead gainers.
