Over 400 South Korea-listed firms cross ₩1 trillion market cap for first time in 2026
Synopsis
South Korea's stock market has not just recovered from the shock of US-Israel strikes on Iran — it has blown past pre-conflict levels. With KOSPI hitting an all-time high of 6,690.9 points and 405 listed firms now valued above ₩1 trillion, the AI rally is rewriting the country's market record books in real time.
Key Takeaways
405 South Korean-listed companies had a market capitalisation exceeding ₩1 trillion won ($679.7 million) as of Wednesday — a first for 2026.
The milestone is up from 377 firms on 27 February , just before US-Israel strikes on Iran rattled markets.
The benchmark KOSPI closed at a record 6,690.9 points on Wednesday, recovering from a single-session drop of as much as 12 percent after the conflict began.
79 firms had a market cap exceeding ₩10 trillion won , reflecting the breadth of the rally.
A revived AI rally ahead of the corporate earnings season is credited as a key driver of the bull run.

South Korea's stock market hit a landmark milestone this week, with the number of listed companies boasting a market capitalisation exceeding ₩1 trillion won ($679.7 million) surpassing 400 for the first time this year. According to data from the Korea Exchange, the country's main bourse operator, 405 companies — including those with preferred shares — had crossed the ₩1 trillion threshold as of Wednesday.
Breakdown by Market
Of the 405 firms, 267 were listed on the benchmark Korea Composite Stock Price Index (KOSPI), while 137 were from the tech-heavy KOSDAQ, and one from KONEX, the local exchange dedicated to small and medium-sized enterprises and venture firms. Among all qualifying companies, 79 firms had a market capitalisation exceeding ₩10 trillion won, underscoring the depth of the ongoing rally.
A Dramatic Turnaround Since February
The milestone marks a sharp recovery from levels seen on 27 February, just before the United States and Israel initiated strikes on Iran. At that point, only 377 companies had crossed the ₩1 trillion mark. The rebound — an addition of 28 firms to the club in roughly two months — reflects renewed investor confidence following the geopolitical shock. Notably, the benchmark KOSPI had fallen as low as 12 percent in a single session after the onset of the conflict before staging its recovery.
AI Rally and Earnings Season Drive the Bull Run
South Korea's equity markets have been on a sustained bullish run, reportedly fuelled by a revived artificial intelligence (AI) rally ahead of the corporate earnings season. The KOSPI closed at 6,690.9 points on Wednesday — its highest level on record — signalling that investor sentiment has not only recovered but surpassed pre-conflict peaks. This comes amid a broader global appetite for AI-linked stocks, with South Korean semiconductor and technology firms positioned as key beneficiaries.
South Korea Eyes Global Offshore Tech Stage
Separately, South Korea is participating in a major US conference on ship and offshore technologies this week. The Korea Trade-Investment Promotion Agency (KOTRA) and the industry ministry have opened a booth at the Offshore Technology Conference 2026 (OTC), held in Houston, Texas, from Monday to Thursday. The delegation plans to showcase 12 domestic companies in the ship-related technology sector. The OTC is an annual global event on offshore technology and energy, and this year's edition is expected to draw approximately 1,300 companies from over 100 nations and more than 30,000 participants, according to KOTRA.
What's Next for Korean Markets
With KOSPI at record highs and the AI-driven momentum intact, analysts and investors will closely watch the upcoming corporate earnings season for confirmation that fundamentals support the rally. Any renewed escalation in the Middle East or a shift in global risk appetite could test the resilience of the market's recent gains.
Point of View
But the more telling figure is the speed of the recovery: 28 companies rejoined the club in roughly two months after a geopolitical shock that sent KOSPI tumbling 12% in a single session. That kind of rebound velocity points to structural demand, not just sentiment. The AI rally is doing heavy lifting here, and South Korean chipmakers and tech firms are riding it hard. The risk, however, is that markets are pricing in an earnings season that hasn't delivered yet — and any disappointment from the tech sector could unwind gains faster than they accumulated.
