Investors and network buyers confronted a striking split in Nokia’s latest quarter as AI-heavy traffic reshaped spending patterns across carriers and hyperscalers, tilting growth from classic radio access networks toward optical transport and IP backbones at cloud scale. Optical network revenue climbed 20% to €821 million, buoyed by data center interconnect upgrades and broader fiber builds as cloud customers lifted orders. Sales to AI and cloud clients jumped 49%, a surge aligned with spending that, in 2026, surpassed $700 billion across hyperscalers and their ecosystems. Management framed AI traffic as roughly 20% of overall network load, predominantly human‑to‑machine today but drifting toward denser machine‑to‑machine flows. That migration demanded higher-capacity optics, deterministic latency, and tighter integration between switching and routing, while mobile RAN softness underscored how capex cycles now favor transport and core intelligence.
Nokia’s growth profile also reflected sharper execution in network infrastructure, where cost control and targeted investment expanded gross margins even as RAN revenue declined. EMEA rose 8.3% on strength in both network and mobile infrastructure, while the Americas posted healthier network gains but weaker mobile, and APAC inverted that pattern with firmer mobile and softer transport. Mission‑critical and defense orders added ballast as public‑sector buyers hardened backbone resilience. Within architectures, demand coalesced around coherent 400G and early 800G optics, segment routing over IPv6 (SRv6), and metro-to-core data center interconnects that compress cost per bit. AI inference bursts and training east‑west flows stressed buffers and QoS, pushing operators toward hierarchical optics with ROADM flexibility and IP fabrics tuned for microburst control. Standard‑related agreements and deepening cloud partnerships signaled a strategy built for sustained optical and IP share gains.
What The Shift Means: Strategy, Timing, and Execution
Building on this foundation, Nokia targeted fiber and IP expansion through 2026 to 2028, pointing to hyperscaler buildouts and carrier upgrades that prioritized coherent pluggables, silicon photonics, and open line systems for multi-vendor agility. The company’s playbook favored three moves: leaner optical cost per bit, IP stacks optimized for AI microbursts, and programmatic integration with cloud control planes. For operators, the next steps were clear: elevate transport investment over marginal RAN adds, deploy 400G/800G where AI east‑west peered with backbones, and standardize on SRv6 with telemetry for closed‑loop assurance. For Nokia, execution hinged on backlog discipline in the Americas, sustained share capture in EMEA, and APAC alignment to transport demand. Private wireless and defense synergies served as cash‑flow stabilizers. Read through that lens, the pivot looked pragmatic rather than abrupt and positioned the vendor to compound gains as AI workloads matured.
