AXT’s surge is driven by surging demand for compound semiconductors in AI data centers, particularly Indium Phosphide, which is critical for high-speed optical components. This has triggered a cascade effect across the upstream supply chain, with Lumentum’s multi-year contract signaling strong market confidence. However, export controls on key materials in China/ China, Hong Kong, China and Taiwan/ Taiwan, China are increasing compliance risks and supply chain fragility. Competitors like NVIDIA are advancing in-house optical chip development, potentially eroding AXT’s competitive moat. While current momentum is strong, the stock’s valuation already reflects high expectations, and any slowdown in growth could trigger a correction. Over the next 12–24 months, compound semiconductors will be central to AI infrastructure bottlenecks, and AXT’s ability to sustain technological leadership and secure supply chains will define its long-term trajectory.
