SK Telecom has strategically reduced its investment in the future of air travel to double down on the future of intelligence.
In late 2025, the company sold a majority of its stake in Joby Aviation, a leading developer of electric air taxis, signaling a clear shift in its capital allocation priorities. This wasn't a sudden move but rather the result of several converging factors that changed the risk-reward calculation for its urban air mobility (UAM) investment.
First, the dream of commercial UAM services faced timeline extensions. Across the industry, including for Joby, timelines for full certification and large-scale commercial operations began to stretch into 2026 and beyond. For SKT, which initially invested with an eye on the Korean market, delays in the domestic 'K-UAM Grand Challenge' program further diminished the near-term strategic value of holding a large equity position. The initial vision of a quick path to Korean skyways became a longer, more uncertain journey.
Second, the eVTOL industry's heavy capital requirements became increasingly apparent. Companies like Joby frequently need to raise large sums of money to fund the expensive processes of certification, manufacturing, and scaling. Joby's own $514 million equity offering in late 2025 was a case in point. While necessary for growth, these funding rounds dilute the ownership stakes of existing shareholders like SKT, making the investment less attractive over time.
Third, and most importantly, SKT defined a new, urgent priority: its 'AI Native' strategy. Unveiled in early 2026, this ambitious plan involves massive investments in AI data centers, sovereign large language models, and AI-powered services. This pivot demanded significant capital and management focus, making the long-dated, pre-revenue UAM investment an obvious source of funds. The opportunity cost of keeping money tied up in Joby became too high when it could be used to fuel SKT's core AI ambitions.
In essence, SKT transformed its UAM bet from a long-term strategic partnership into a successful financial trade. By selling near the stock's peak in late 2025, it crystallized a gain of over 130% on the sold portion and avoided the subsequent 24% drop in Joby's share price. The capital was then redeployed to a field where SKT aims to be a leader, not just a partner.
- UAM (Urban Air Mobility): A system for air transportation in and around urban areas, often envisioned using electric aircraft like air taxis.
- eVTOL (electric Vertical Take-Off and Landing): Aircraft that use electric power to hover, take off, and land vertically, like a helicopter, but can fly like a plane.
- K-UAM Grand Challenge: A multi-phase government-led program in South Korea to demonstrate and verify the safety of UAM and accelerate its commercialization.
