Singapore-based infrastructure firm Keppel has signed an indefeasible right of use (IRU) agreement with a global hyperscaler for the final available fiber pair on its Bifrost subsea cable, which connects Singapore to the US West Coast. The deal marks a milestone for the project, as all five fiber pairs are now committed, pushing the total estimated contracted value to $1.3 billion.
An IRU is a long-term lease agreement that gives the buyer exclusive rights to use a specific fiber pair for a set period, typically 15 to 25 years. Hyperscalers—large cloud providers like Amazon Web Services, Microsoft Azure, and Google Cloud—often use such deals to secure dedicated capacity for handling massive data flows.
Bifrost: A Key Trans-Pacific Route
The Bifrost cable spans more than 20,000 kilometers, running from Singapore through Indonesia and other points before reaching the US West Coast. It is designed to handle high-volume data traffic, with a total capacity exceeding 240 terabits per second (Tbps) across its five fiber pairs. That capacity is now fully allocated to a mix of telecom operators and big tech buyers, reflecting the surging demand for bandwidth driven by cloud computing and artificial intelligence workloads.
Subsea cables remain the backbone of global internet connectivity, carrying over 95% of intercontinental data traffic. As AI models require vast amounts of data to be transferred between data centers, demand for such infrastructure has grown sharply. The Bifrost cable is positioned to serve that need, particularly for traffic between Asia and North America.
What It Means for Investors
For Keppel, the completion of Bifrost's capacity sales provides a clear revenue stream and validates its investment in subsea infrastructure. The $1.3 billion contracted value locks in long-term income from IRU agreements, which typically generate steady cash flows over the lease period. This can be attractive for infrastructure-focused investors who value predictable returns.
The deal also underscores the broader trend of hyperscalers investing directly in network capacity. Rather than relying solely on telecom carriers, big tech firms are increasingly securing their own fiber pairs to ensure low latency and high reliability for AI and cloud services. This shift has benefited companies like Corning, which manufactures optical fiber and has seen strong demand from AI-related projects, as noted in a recent BofA report on Corning's optical unit.
However, investors should be aware that subsea cable projects carry execution risks, including construction delays, regulatory hurdles, and potential damage from natural disasters. Keppel's ability to fully contract Bifrost's capacity suggests strong market confidence, but the long-term profitability will depend on maintenance costs and the cable's operational lifespan.
Broader Market Context
The news comes amid a broader rally in AI-related infrastructure stocks, though some analysts have warned that the AI chip rally may be peaking as focus shifts to hyperscalers, as highlighted in a Morgan Stanley report. For Keppel, the Bifrost deal positions it as a key player in the AI data pipeline, but the company's overall performance will also depend on its other infrastructure assets, including data centers and energy projects.
Investors watching the subsea cable space should also note that Starlink's satellite internet service is seen as a growing threat to traditional cable broadband, according to Morgan Stanley, but subsea cables remain essential for long-haul, high-capacity routes like trans-Pacific links. The Bifrost cable's focus on AI and cloud traffic differentiates it from consumer-oriented services.
Looking Ahead
With all fiber pairs now sold, Keppel will likely focus on the cable's operational launch and ongoing maintenance. The company may also explore additional subsea projects or expansions, given the sustained demand for bandwidth. For everyday investors, the key takeaway is that AI and cloud growth are driving tangible investments in physical infrastructure, creating opportunities for companies that build and operate these networks. As always, diversification remains important, as individual projects can face unforeseen challenges.
