Nextrade Gains Ground in South Korea’s Equity Market, but Growth Faces Regulatory Caps and Uncertainty

Publication date: 2025-10-20 • Last updated: 2025-10-20

The platform’s longer hours and lower costs have allowed Nextrade to win market share quickly; some stocks such as Doosan Enerbility are now traded more on Nextrade than on the 70-year-old Korea Exchange (KRX). Nextrade operates a 12-hour daily window, almost double KRX’s 6.5 hours, opening earlier and staying active late into the evening.

Retail traders, often referred to as “ants,” have flooded the platform; they account for a large share of Nextrade activity and have shown preference for speed, extended sessions, and lower fees. The pricing model, which highlights price-based best-execution, means orders can be routed to the venue offering the best deal automatically.

Because Nextrade does not list IPOs, some market participants question its long-term capacity to sustain growth. Foreign participation has climbed to about 11% from near zero at launch, while domestic institutions remain relatively cautious amid ongoing system stability concerns—despite no major outages reported.

Retail traders move to Nextrade en masse for speed and flexibility

Nextrade’s appeal lies in speed and cost. Retail investors, known for trading on impulse and during commutes, have gravitated toward the platform as its 12-hour window and lower transaction costs make intraday trading more attractive. In addition to crypto and U.S. ETFs, Nextrade now captures a notable share of Magnificent Seven stock activity and other high-liquidity names.

Transaction fees are estimated to be 20–40% cheaper than on the Korea Exchange, and brokers employ a price-based routing system that automatically selects the most favorable venue. This has helped Nextrade attract order flow rapidly, reshaping the domestic trading landscape.

On IPOs, Nextrade remains focused on liquidity rather than primary listings. Foreign participation has risen, with institutions and brokers noting gradual diversification of investors, though domestic institutions have yet to fully embrace the platform. Regulators have acknowledged near-term volatility concerns, even as Nextrade reports no major outages.

Regulators cap Nextrade’s growth while Seoul pushes U.S. tariff deal

Regulators have maintained a 15% overall market-volume cap while attempting to manage Nextrade’s rapid expansion. To stay under the cap, Nextrade temporarily suspended around 150 stocks in August and September, creating a disparate view of market share by value versus volume.

In the United States, 80-plus ATS platforms handle roughly 20% of market value, while in Japan the three major ATS players split around 10% of activity. Nextrade’s growth is described by observers as unprecedented, with early signals suggesting a structural shift in Korea’s equity trading patterns.

“It’s unprecedented globally,” noted Kang Sohyun, senior research fellow at the Korea Capital Market Institute. “If you compare to markets with one large exchange and smaller bourses, such as Australia and Japan, Nextrade’s expansion has been very rapid.”

The legal groundwork for Nextrade was laid in 2013 as part of Korea’s modernization plan, with preliminary approval returning only in 2023. Kim Haksoo, Nextrade’s CEO, previously served as a financial regulator, underscoring the regulatory emphasis on stability and compliance.

Meanwhile, South Korea’s broader economic policy has been evolving. Kim Yong-beom, the presidential policy chief, reported progress on tariff talks with the United States, while officials met U.S. negotiators in Washington. The discussions center on a proposed $350 billion investment fund and continuing tariff reductions on Korean goods.

In parallel, top Korean corporate leaders—Hyundai Motor, SK Inc., Hanwha—participated in high-profile meetings tied to potential cross-border investment and trade arrangements, a signal that policy and business interests remain closely aligned as the Asia-Pacific trade landscape shifts.
