Riding the AI Wave: 3 Stock Sectors Set to Win Big from Indonesia's Data Center Boom

The artificial intelligence revolution is no longer just a buzzword in Silicon Valley; it has officially landed in the Indonesian capital markets. As global tech giants look for new hubs to host their massive computing needs, Indonesia is positioning itself as a primary contender. The momentum shifted into high gear following the high-profile collaboration between PT Indosat Ooredoo Hutchison Tbk. (ISAT), Nvidia, and Nokia to establish an 'AI Factory' dubbed Zankore. This isn't just a win for telecommunications; it’s a catalyst for a massive shift in several key stock sectors.

For investors looking to capitalize on this digital gold rush, the opportunity isn't limited to just one or two companies. The data center ecosystem is vast, involving physical infrastructure, specialized real estate, and the high-speed fiber optic networks that connect them. To help you navigate this complex landscape, we have broken down the three primary sectors currently benefiting from the data center expansion and the specific stocks you should keep on your radar.

The Frontline: Direct Data Center Providers

The most obvious beneficiaries are the companies that own and operate the facilities themselves. These players are currently in a massive 'arms race' to increase their Megawatt (MW) capacity to meet the demands of hyperscalers.

Leading the pack is PT DCI Indonesia Tbk. (DCII), often cited as the gold standard for data centers in the region. As of 2026, DCII has a capacity of 128 MW, but their roadmap is staggering—they have the potential to scale up to over 2,000 MW. Their key sites include the H1 Campus in Cibitung (potentially 220 MW), the H2 Campus in Karawang (targeting over 600 MW), and the massive H3 DC Park in Sky Bintan, which could reach 1,000 MW on its own.

Telecommunication giants are also pivotally shifting their weight toward this sector. PT Indosat Ooredoo Hutchison Tbk. (ISAT), through its partnership with BDx, has already moved Rp2.6 trillion worth of assets into BDx Indonesia, which currently manages 150 MW across four key locations. More impressively, their Zankore project aims for a colossal 1 GW capacity, with the first 200 MW phase in Batang expected to be ready by mid-2027. Meanwhile, PT Telkom Indonesia (Persero) Tbk. (TLKM) is operating through NeutraDC. With a target of 300-500 MW by 2030, Telkom is aggressively expanding its footprint in Cikarang and Batam, already generating significant revenue and profit from these digital assets.

Newer entrants are also making waves. PT NexAI Digital Infrastructure Tbk. (MGLV) recently acquired MettaDC and is developing a 60 MW site in Batang. Similarly, PT Dian Swastatika Sentosa Tbk. (DSSA) has partnered with Korea’s KIRA SG One to build AI-ready data centers, targeting an initial 60 MW capacity by the end of 2026.

The Landlords: Industrial Estates as Digital Hubs

Data centers require more than just servers; they need massive amounts of land with specialized infrastructure and power access. This has turned certain industrial estate stocks into 'hidden' data center plays.

PT Puradelta Lestari Tbk. (DMAS) is perhaps the biggest winner in this sub-sector. In the first half of 2026, a staggering 92% of their total revenue came from data center clients, including global titan Microsoft. Their ability to provide ready-to-build plots for hyperscalers has made them a primary beneficiary of this trend.

Other estates are following suit. PT Surya Semesta Internusa Tbk. (SSIA) recently facilitated a 12-hectare land deal for Indosat’s expansion in Karawang. PT Bekasi Fajar Industrial Estate Tbk. (BEST) hosts the massive DCII campus, while PT Kawasan Industri Jababeka Tbk. (KIJA) maintains a massive land bank across Cikarang, Kendal, and Morotai that could easily accommodate future digital infrastructure surges.

The Digital Highway: Fiber Optic Infrastructure

A data center is useless without the 'pipes' to move data at lightning speed. This is where fiber optic providers come in, providing the backbone and subsea cables necessary for AI processing and global connectivity.

PT Sarana Menara Nusantara Tbk. (TOWR) currently boasts the largest network with 170,000 km of fiber optics. While much of this is used for cellular towers, their subsidiary iForte is specifically pivoting toward the data center market. Not far behind is PT Ekamas Mora Republik Tbk. (MORA), a Sinarmas Group entity that now controls over 166,000 km of network following its strategic merger with MyRepublic.

Telkom (TLKM) has also taken a strategic step by spinning off its fiber assets into InfraNexia. This new entity manages 112,000 km of cables, including critical subsea links. Indosat (ISAT) isn't sitting still either; they’ve formed a joint venture with PT Nusantara Fiber Teknologi to manage an 86,000 km network valued at over Rp11.7 trillion.

Strategic Takeaways for Investors

While the hype around data centers is palpable, it is crucial to approach these stocks with a balanced perspective. The expansion requires massive capital expenditure (CAPEX), which can impact short-term cash flow. For instance, MGLV is taking on significant loans to fund its growth, which comes with interest obligations.

Investors should focus on the long-term contribution of these data center units to the company's overall bottom line. For traders, the price action in stocks like DCII, ISAT, and DMAS often provides technical entry points during news cycles. Whether you are a fundamental investor or a technical trader, the digitalization of Indonesia’s economy is a multi-year trend that is only just beginning.
