The story of Taiwan's economic miracle has taken an unexpected turn. Lin Tsung-chi, the 85-year-old founder of King Slide Works, a company specializing in furniture hardware manufacturing, has unexpectedly become the wealthiest person on the island. The reason is not traditional semiconductors, but a seemingly secondary component: rails for server racks.

Since the beginning of the year, King Slide's market capitalization has soared by nearly 280%. Investors have recognized the company's unique position in the new artificial intelligence economy. The seemingly modest rail mechanisms, which allow heavy servers to be slid out for maintenance without disrupting the critical cooling system, have proven to be a strategic product.

My analysis of the market situation shows that King Slide controls about 80% of the global market for high-performance server rails. This dominance allows the company to set nearly monopoly prices.

Margins chipmakers dream of

King Slide's financial performance looks sensational even compared to industry leaders. In the last quarter, the company's gross margin reached 87%. For comparison: Nvidia's figure is around 75%, and TSMC's is 68%. Just a few years ago, King Slide's margin was at 50%, highlighting the rapid pace of change.

The company's executive vice president, Jay C. Wang, attributes this profitability to two decades of engineering development. The company has created specialized mechanisms capable of withstanding the loads of modern AI systems. When a single rack costs millions of dollars, clients are willing to pay for reliability rather than skimp on details.

Lin's fortune, according to Forbes estimates, has reached $20.3 billion, allowing him to surpass Foxconn founder Terry Gou, whose wealth has also grown thanks to AI infrastructure.

New architectures — new opportunities

King Slide's future prospects look promising. Cloud giants are actively transitioning to their own AI accelerators, increasing equipment density, and implementing liquid cooling. Each such transition requires redesigning server and rack structures, creating new demand for rails.

The examples of Google and Alibaba are telling. The former received an option to purchase up to 58.97 million shares of Marvell Technology as part of an expanded agreement on AI processor development. The latter is raising $10.2 billion to develop its own neural network stack. Each new accelerator differs in dimensions and heat dissipation, requiring a custom rack and, accordingly, its own rails.

However, competition is intensifying. According to Daiwa Securities estimates, King Slide's share in supplies for Nvidia systems could drop to 75% as early as next year, as the chipmaker expands its pool of suppliers. Large data center operators will be able to use this to negotiate price reductions.

Nevertheless, the company is confidently looking to the future, expanding production in Houston to serve North American clients. Demand for specialized hardware will grow alongside the scaling of AI infrastructure, and King Slide intends to maintain a direct dependence of its business on these investments.

My expert opinion: King Slide's story is a vivid example of how infrastructural "trifles" become critically important assets in the AI era. While all attention is focused on chips, companies controlling niche components with high margins may prove to be a more profitable investment than the semiconductor manufacturers themselves.
