Astera Labs and Credo Technology Group are emerging as pivotal players in the AI infrastructure landscape as demand for high-speed connectivity surges amid significant investments from major cloud providers like Amazon. Astera Labs reported a remarkable 115% revenue growth to $852.5 million in 2025, bolstered by a solid gross margin of 75.6%. Its focus on PCIe and CXL chips, which streamline data transfer within AI server clusters, positions the company advantageously as AI workloads become increasingly bandwidth-intensive. Meanwhile, Credo Technology’s revenue soared 201.5% to $407 million in the third quarter, with more than 90% of its sales deriving from data center solutions, reflecting a robust demand for optical and electrical connectivity.
Amazon is set to invest a staggering $200 billion in AI infrastructure in 2025, primarily to scale its partnership with Anthropic. This investment includes increased cloud credits and infrastructure support through Amazon Web Services (AWS), aimed at enhancing the capabilities of large language models. As AI applications evolve, the need for advanced networking solutions within data centers is becoming a critical concern, with training large models requiring thousands of GPUs clustered together, necessitating faster interconnects. Data center interconnect demand is projected to grow between 17% and 20% annually through 2028, underscoring the potential for suppliers like Astera and Credo.
Astera Labs operates in a specialized niche that is often overlooked by investors. By linking CPUs, GPUs, and memory inside AI servers, its products directly address the bottlenecks that can limit performance. The company turned consistently profitable in 2025, generating $219 million in net income, a testament to its strategic alignment with the growing hyperscaler AI spending, especially from Amazon. As the demand for more powerful AI models escalates, the internal data pathways become increasingly strained, creating a direct correlation with Astera’s growth.
In comparison, companies like Marvell Technology and Broadcom reported revenue growth of 42% and 24%, respectively, with gross margins of 59% and 67.8%. Astera’s performance clearly stands out against its peers, highlighting its critical role in supporting the infrastructure that underpins AI advancements.
On the other hand, Credo Technology specializes in high-speed connectivity solutions that facilitate efficient data transmission between servers. Its chips, designed for low power consumption and fast transmission over long distances, are essential for large distributed systems where AI models operate. With a gross margin of 67.8%, Credo’s strong data center exposure positions it favorably as demand for efficient networking solutions grows. However, the company faces risks due to its high concentration of customers, with three clients accounting for 90% of revenue. This reliance raises concerns about potential volatility should major clients shift vendors or alter spending strategies.
The partnership between Amazon and Anthropic highlights a broader trend in the AI sector: the growing importance of infrastructure that supports rapid compute scaling. As Amazon deepens its commitment to Anthropic, the ripple effect will be felt throughout the supply chain, benefiting those who provide the necessary connectivity solutions. Both Astera and Credo stand to gain from this trend, albeit from different angles. Astera enhances data flow within servers, while Credo optimizes data movement across networks.
As the AI arms race accelerates, understanding the underlying infrastructure that supports major advancements becomes increasingly critical for investors. While attention often focuses on high-profile names like Amazon and NVIDIA, significant opportunities lie in companies that provide essential components of AI architecture. Both Astera Labs and Credo Technology exemplify this potential, making them key players to watch as AI infrastructure continues to evolve and expand.
In summary, as the partnership between Amazon and Anthropic unfolds, the demand for high-speed connectivity is poised to increase dramatically, offering substantial opportunities for companies like Astera Labs and Credo. With their respective focuses on internal and external data transfer solutions, they are well-positioned to capitalize on the ongoing AI infrastructure investments that are reshaping the technology landscape.
