Investor discussions at the Morgan Stanley China Summit 2026 revealed a clear divergence in expectations between two technology segments: AI transceivers and smartphones.
On the AI transceiver front, the prevailing view among investors has shifted toward co-packaged optics as the base case for development. That view is accompanied by more tempered and balanced perspectives on how that evolution will affect the AI transceiver market overall. Both corporate management teams and investors represented at the summit signaled an expectation of strong demand for AI transceivers over the next two to three years. Despite that shared demand outlook, attendees did not reach agreement on which companies or which slices of the market structure will reap the largest gains from that demand.
By contrast, sentiment around the smartphone industry has moved noticeably negative since early 2026. Delegates at the summit cited rising memory costs as a primary concern, and a majority of investors now expect those cost pressures to translate into weaker smartphone shipments and compress company profit margins. The change in tone marks a clear shift from earlier in the year when sentiment was less uniformly bearish.
Within the smartphone supply chain, assessments were not uniform. Suppliers with exposure to Apple were judged more favorably by investors, while confidence in vendors that primarily serve Android device makers remained weak. The differentiation suggests investors are parsing supplier risk and resilience based on end-market exposure.
Summit participants therefore painted a mixed picture: a broadly constructive demand outlook for AI transceivers coupled with uncertainty over beneficiaries, and a deteriorating outlook for smartphones driven by component cost inflation and its anticipated impact on shipments and margins.
Impacted sectors - semiconductor components and optical modules tied to AI transceivers; smartphone hardware and the broader mobile-device supply chain.
Information limitations - Attendees voiced expectations and assessments at the summit but did not converge on which specific companies would gain most from AI transceiver demand nor provide detailed quantitative forecasts for shipment or margin impacts beyond the directional views reported above.
