Korea’s generative AI momentum is entering a defining moment. As Upstage prepares for what could become the nation’s first AI unicorn IPO, the ripple effect extends across the country’s deep-tech ecosystem — from semiconductor innovators like Rebellions and DeepX to policymakers shaping how capital flows into frontier industries. The outcome could redefine Korea’s place in the global AI race.

Upstage Sets the Stage for Korea’s First Generative AI Unicorn IPO

Upstage, one of Korea’s leading generative AI startups, is preparing for a landmark listing that could value the company in the multi-trillion-won range. According to industry sources, the company has begun exploring a pre-IPO round targeting global institutional investors, aiming to raise USD 300 million (KRW 430 billion) at a USD 900 million (KRW 1.3 trillion) valuation.

If completed, the IPO — expected in the second half of 2026 — would make Upstage Korea’s first publicly listed generative AI company. The move follows a series of record-breaking performances in global AI equity markets, as investors seek exposure to companies with in-house large language model (LLM) capabilities.

Upstage, founded in 2020, is known for its frontier-grade LLM “Solar Pro 2”, featuring 31 billion parameters. The model was the only Korean LLM recognized among the world’s top 10 by AI evaluation firm Artificial Analysis earlier this year. The company’s enterprise AI deployment projects with domestic financial institutions and its growing presence in Southeast Asia have fueled steady revenue growth.

A Market Searching for Its First AI Unicorn

Despite Korea’s strength in hardware and software integration, it has yet to produce a single generative AI unicorn — a stark contrast to countries like France (Mistral AI), Germany (DeepL), and Japan (Sakana AI), where LLM-based startups have already crossed the billion-dollar valuation mark.

Hence, Upstage’s IPO now becomes a reflection: does it mean Korea’s venture ecosystem and capital markets can sustain global-scale deep-tech growth?

The company’s 2025 revenue already surpassed its 2024 annual total, reaching KRW 17 billion in the first half alone, with operating losses narrowing sharply. Analysts view this as evidence that enterprise-grade AI adoption is translating into tangible results.

Meanwhile, the domestic equity market’s renewed appetite for AI is creating favorable conditions. The recent KOSDAQ debut of Nota AI, a model optimization startup, achieved a market capitalization of KRW 1 trillion within three days, signaling a strong investor response to AI-driven listings.

Rebellions, DeepX, and the Next AI IPO Wave

Upstage’s IPO momentum is amplifying investor focus on Korea’s broader AI semiconductor sector, where several startups are preparing for listings.

Rebellions, which raised KRW 340 billion in a pre-IPO round in September at a KRW 1.9 trillion valuation, has already selected Samsung Securities as its lead underwriter. DeepX and FuriosaAI, both valued near KRW 1 trillion, are also considered likely to pursue listings in 2026.

These three companies — Rebellions, DeepX, and FuriosaAI — form Korea’s “AI semiconductor trinity”, a group receiving policy and investor attention as the government pushes for domestic AI chip sovereignty under its broader “AI Transformation (AX)” strategy.

Market observers note that these firms’ valuations and upcoming IPOs could serve as a real-world measure of Korea’s deep-tech investment maturity, particularly as government-backed funds and institutional capital seek high-impact innovation opportunities.

A Test of Korea’s Deep-Tech Capital Infrastructure

Upstage’s trajectory is being watched closely by policymakers at the Ministry of SMEs and Startups (MSS) and Korea Venture Investment Corp. (KVIC), both of which have emphasized that deep-tech funding must evolve beyond short-term venture models.

Analysts suggest that the Upstage–Rebellions–DeepX wave will test whether Korea’s venture policies, regulatory frameworks, and exit markets are ready to support high-risk, capital-intensive AI companies. The upcoming Venture 4.0 Roadmap, set to outline the government’s next-phase startup investment policy, is expected to address these structural gaps.

The Upcoming IPO Debut of Upstage: Korea’s Defining AI Moment

According to Professor Choi Byung-ho of Korea University’s AI Research Institute via Seoul Economic Daily, the rise of Korean AI companies represents more than economic success — it’s a strategic transition toward an AI-powered industrial economy, stating:

“To become a true AI powerhouse, Korea must achieve synergy between LLM development and domestic semiconductor innovation. If AI startups like Upstage and Rebellions can expand through IPOs, it will accelerate both global competitiveness and talent cultivation.”

As Korea’s venture market prepares for what could become its first AI IPO relay, the outcome will signal whether the country’s capital markets — and policy frameworks — can finally match its technological potential.
