Three of South Korea’s largest conglomerates have quietly completed one of the biggest enterprise AI rollouts of 2026. Samsung, SK Group, and LG are now deploying AI agents across entire workforces, marking a decisive end to the caution that kept major corporations on the sidelines for the past few years.

The shift is significant because these companies were not AI skeptics. They were AI-scared, and for understandable reasons. Now they are back, and the scale of their re-entry says something important about where enterprise AI adoption actually stands.

Samsung Reverses Its Ban

The Samsung story is the most dramatic. In 2023, Samsung became one of the most cited examples of corporate AI risk when an engineer accidentally pasted proprietary chip design data into ChatGPT. Samsung banned external AI tools within weeks.

Three years later, that ban is over.

Samsung Electronics has opened ChatGPT, Claude, and Gemini Enterprise to its DX Division employees as of June 2026. The rollout followed a two-month internal pilot involving 2,500 employees who tested the tools inside a secure sandbox environment. Employees who complete mandatory security training get access. Those who do not, do not.

The approach is careful but it is not hesitant. Samsung is not trialing AI in one department and watching for twelve months. It is deploying to one of its largest divisions with a clear framework for expansion.

Samsung SDS, the IT services arm of the group, had already been moving in this direction. At CES 2026 in January, the company demonstrated AI agents for workplace productivity and declared an “AI-agent-driven AI transformation.”

SK Group Builds Its Own AI Agents

SK Group is taking a different path. Rather than licensing external models and wrapping them in access controls, SK is building proprietary AI tools tuned to its specific workflows.

SK Telecom has launched A.Biz Cowork, an internal AI agent that learns employee work patterns over time and automates repetitive tasks. The system runs on SK Telecom’s proprietary LLM and is designed specifically for Korean enterprise workflows. SK hynix, the chip division, has its own generative AI platform called GaiA, which engineers use to synthesise decades of chip design patterns and get optimisation suggestions.

SK Broadband is running its AI Agent Lab from March through October 2026, an intensive training program that aims to more than double the share of employees with intermediate or higher AI proficiency, from 9 percent of the workforce to 20 percent.

And SK AX, the group’s enterprise AI unit, signed a partnership with OpenAI in May 2026 to accelerate that transformation externally, helping Korean businesses build on top of the models SK is already using internally.

LG Expands AI Training Across Leadership

LG is taking a training-first approach. The group has expanded AI education to executives and employees across its divisions, using a mix of frontier models including ChatGPT, Claude, Gemini, and Microsoft Copilot. LG CNS, the IT subsidiary, has secured partnerships with both OpenAI and Anthropic, while LG AI Research continues to develop Exaone, the group’s own 300-billion-parameter multimodal model.

The combination of external tools and proprietary model development mirrors what major technology companies in the United States did a year ago. Korea is not following the same playbook by accident.

What This Actually Means

The Korea Herald framed this as “Korea Inc. races to put AI agent on every desk,” which is an accurate description but undersells the implication.

Samsung, SK, and LG collectively employ hundreds of thousands of people and anchor supply chains that extend across global manufacturing, semiconductors, telecommunications, and consumer electronics. When companies at this scale move from caution to deployment, they are not making a bet. They are acknowledging that the bet has already been made and won.

There are a few things worth noting for business leaders watching this:

Security concerns did not stop adoption, they shaped it. Samsung’s data leak in 2023 was cited as a reason to ban AI. Three years later, the same concern produced a robust access-control framework that allows deployment rather than preventing it. The lesson is that building the security scaffolding takes time but is solvable.

Proprietary versus external is not a binary choice. SK’s approach uses both. SK Telecom builds its own agent on its own LLM for core workflows. It licenses OpenAI for the business unit that sells AI transformation services. LG does the same with Anthropic and OpenAI side by side. Organisations do not have to bet on one vendor.

Training is the actual bottleneck, not access. Samsung’s pilot and SK Broadband’s six-month training program both point to the same constraint: companies have the tools, but employees need to know how to use them productively. AI literacy is the implementation layer that vendors rarely talk about, but every enterprise deployment depends on it.

Full workforce deployment is now the baseline expectation. None of these rollouts are department-level pilots. Samsung opened to a full division. SK Broadband aims to train all staff. LG is running executive education alongside employee programs. The question for global businesses is no longer whether to deploy, but how fast and to whom first.

What This Means for Business

The Korean chaebol rollout is a useful benchmark for any business evaluating its AI timeline. These companies are not cutting-edge startups. They are large, bureaucratic, risk-aware organisations with complex IT environments and a history of being burned by AI tools. If they have moved to full workforce deployment, the “we’re not ready” argument is getting harder to sustain.

For business leaders, the practical takeaway is straightforward. The firms that waited for AI to prove itself had a reasonable position in 2023. That window has closed. The firms building AI into operations now, even imperfectly, are accumulating a learning advantage that compounds over time.

The ones still watching and waiting are falling further behind every quarter.

If your business is still in the evaluation phase, Enterprise DNA’s Omni Advisory service can help you build a deployment roadmap that accounts for your security requirements, existing systems, and team capabilities. The chaebols spent two months building their sandbox. You do not have to start from scratch.
