A research report from CITIC Securities reveals that the capital expenditures of North America's four leading cloud service providers maintained their rapid growth trajectory in the second quarter of 2026, with some providers even revising their full-year forecasts upwards. Notably, several key performance indicators for Amazon AWS surpassed expectations, and its CEO announced that the breakeven point for investments in servers and network infrastructure would be achieved within the next three years. This marks the emergence of a virtuous cycle in AI investment and returns, effectively dispelling market concerns about the long-term viability of AI-related capital expenditures. With cloud providers' performance underscoring the business growth driven by AI, the scale of AI clusters is poised for further expansion. Propelled by multiple drivers, the optical interconnectivity sector is expected to sustain its rapid growth momentum. CITIC Securities remains resolutely optimistic about the medium- to long-term development prospects of the optical communication industry.
