Goldman Sachs significantly raises forecast for optical transceiver market: size may reach $148.5 billion by 2028
① High-speed products have become the core growth driver, with the market size for 800G and above optical transceivers expected to increase from $45.2 billion in 2026 to $129.5 billion in 2028; ② The expansion of AI rack-scale systems, increased penetration of ASICs, and higher optical transceiver usage per AI chip are jointly accelerating the ramp-up of demand for 1.6T and 3.2T modules; ③ The penetration rate of silicon photonics in high-speed optical transceivers continues to rise, while Co-Packaged Optics (CPO) remains primarily in the early adoption phase in the short term.
Major Wall Street banks interpret this year's SEMICON highlights: Advanced packaging is evolving toward 3D system integration, while CPO manufacturing bottlenecks lie in testing.
SEMICON 2026 sends new signals for the semiconductor industry: advanced packaging is upgrading toward 3D system integration, CoWoS capacity continues to expand and spill over to OSATs, CPO is accelerating mass production, while testing and equipment lead times have become new bottlenecks, and the AI ASIC ecosystem is further maturing. UBS Group is bullish on Taiwan Semiconductor's 3DFabric capacity expansion, Citi focuses on CPO manufacturing, and Nomura warns of capacity constraints in testing and equipment segments, as AI-driven capacity expansion accelerates into the backend processes.

Comba Telecom Reports Stable Capital Structure and Compliance for August 2026
Cost per million tokens drops below $1! Goldman Sachs: “Volume surge, price collapse” shakes the logic of AI capital expenditure.
Goldman Sachs’ latest report shows that the SDLLMTK index, which measures AI inference pricing, plummeted by 29% in August alone, falling below the $1 per million tokens threshold for the first time and marking a cumulative 50% decline from its peak. Price cuts, user migration to low-cost open-source models, intensifying competition, and local inference are structurally eroding the per-token pricing model. The widening divergence between rising volume and falling prices is dismantling the core narrative that “more tokens equal more revenue.”
