KIWOOM SECURITIES

What KIWOOM SECURITIES does

Kiwoom Securities is one of South Korea's top five retail brokerages and claims the #1 market share position in Korean equities, operating primarily through its proprietary mobile trading platform HeroS# (also branded "Youngwoongmun S#"). The platform integrates real-time trading with a chat-based community service that has attracted 1.5 million users in approximately four months, averaging 150,000 daily active users and 800,000+ monthly users, with direct analyst participation and AI-based information summarization. Kiwoom has deployed a Korean-first commercial explainable AI investment service through a three-party strategic MOU with LG AI Research (leveraging its EXAONE large language model) and the London Stock Exchange Group (providing global financial data across 190+ countries), enabling retail investors to receive stock-level predictions with plain-language reasoning and supporting evidence.

The company's revenue model is diversified across multiple streams: trading commissions from brokerage activity, interest income from margin lending (Korean margin debt hit a record KRW 36.47 trillion, with top 10 brokerages earning KRW 600 billion in Q1 2025), a newly launched commercial paper issuance business that surpassed KRW 1 trillion in balance within roughly three months of its December 2025 launch, and venture capital investments (with a ~KRW 750 billion existing balance and plans to deploy KRW 600 billion in new venture capital in 2026). Geographic expansion is being executed through distribution partnerships with Webull (25 million global customers across 14 markets) and Interactive Brokers to offer foreign omnibus accounts, giving international investors real-time access to Korean equities without opening domestic accounts. Marketing channels include a notable Gen Z-focused esports sponsorship of DRX (rebranded "Kiwoom DRX") and ESG initiatives such as employee blood donation drives and student scholarships.
