Why Credo and Astera Soared After Oracle and Broadcom's Earnings

Why It Matters

The surge underscores how expanding AI data‑center capacity directly fuels niche copper‑interconnect suppliers, positioning them for revenue upside while highlighting concentration risks.

Key Takeaways

• Oracle plans 10 GW data‑center capacity in three years.
• Copper interconnects favored in scale‑up server architectures.
• Credo’s HiWire cables beat optics on cost, power.
• Astera’s smart retimers drive majority of its revenue.
• Customer concentration remains a key risk for both firms.

Pulse Analysis

The AI‑driven data‑center boom is reshaping infrastructure spending, with hyperscale operators adding megawatts of compute power at unprecedented rates. Oracle’s recent earnings revealed a commitment to deploy 10 GW of new capacity within three years, effectively doubling its annual build‑out pace. This acceleration translates into higher demand for internal server connectivity, where copper‑based solutions still hold a cost and power advantage over emerging optical technologies, especially in dense, scale‑up configurations.

Credo Technology’s HiWire active electrical cables and Astera Labs’ smart retimers are positioned to capture this demand. Their copper‑centric products enable longer runs and lower latency while consuming less power than traditional passive copper or costly optical links. Broadcom’s commentary that scale‑up architectures will rely on copper well into 2028 reinforces the market’s near‑term preference for these solutions. Meanwhile, both firms are investing in optical capabilities to hedge against a future shift toward co‑packaged optics, ensuring they can adapt as the technology landscape evolves.

Investors, however, should weigh the concentration risk inherent in both companies. A handful of customers currently account for the majority of revenue—84 % for Astera and 87 % for Credo—making any slowdown at these accounts a material threat. Nonetheless, the broader trend of rapid data‑center expansion, coupled with sustained copper demand, provides a compelling growth narrative. As AI workloads continue to scale, the connective tissue supplied by Credo and Astera will remain critical, offering a nuanced blend of short‑term upside and long‑term strategic positioning.
