Introduction
In a significant move that speaks volumes about Arm Holdings’ just hit a speed bump. The company quietly backed out of acquiring UK-based Alphawave — a move that would’ve fast-tracked its entry into the elite club of AI chipmakers. While the deal fell apart, the message was loud and clear: Arm isn’t content with just licensing chip designs anymore. It wants a front-row seat in the $60 billion custom AI chip market — and it’s willing to shake things up to get there.

Key Takeaways:
Arm’s failed acquisition of Alphawave highlights its ambition to enter the AI chip market.
SerDes technology is crucial for enabling high-speed data transfer between chips, which is vital for AI workloads.
The AI chip market is expected to grow to $60 billion by 2028, with fierce competition from Nvidia, Broadcom, and Marvell.
Arm may choose to build SerDes technology in-house, which could take at least two years.
Arm’s push into AI chips is a long-term strategy to compete directly with industry leaders and meet the growing demand for custom AI hardware.
Arm’s Bold Move into AI Chip
Arm Holdings has traditionally been known for designing low-power processors and licensing its architecture to a wide range of companies.
However, as AI technologies evolve, the need for high-performance chips has skyrocketed. Arm’s strategy seems to be evolving to meet this demand head-on.
A crucial piece of AI chip infrastructure is the data transfer technology that connects chips, and that’s where Alphawave comes in. The SerDes technology developed by Alphawave is a critical enabler of high-speed chip-to-chip communication.
This technology allows AI models to scale, train, and run effectively on high-performance hardware. If Arm had successfully acquired Alphawave, it could have integrated SerDes into its own chip designs, giving it a competitive edge in the growing AI market.

Why SerDes Matters in AI Chip Design
Key to AI Performance: SerDes technology enables fast and efficient data transfer between processors, essential for training and running complex AI models.
Handling Larger Models: As AI models grow, the need for faster data communication increases. Advanced SerDes technology offers a competitive edge in managing these larger, more complex models.
Scalable AI Infrastructure: SerDes is crucial for integrating processors into scalable systems that can handle vast data loads, enabling efficient AI infrastructure.
Rising Demand for Custom AI Chips: The AI chip market, expected to reach $60 billion by 2028, is driving demand for custom chips optimized for AI workloads, with SerDes acting as a key differentiator.
Competitive Pressure: Companies like Broadcom, Marvell, and Nvidia lead in SerDes development, placing Arm at a disadvantage as it works to catch up in the AI space.

A Strategic Setback for Arm
While Arm’s attempt to acquire Alphawave was a significant move, it ultimately fell apart. One of the key reasons for the collapse of the deal is thought to be Alphawave’s ties to a Chinese company that has been blacklisted.
This connection reportedly raised concerns among potential investors and may have led Arm to reconsider its position.
However, the real story here is not just about a failed acquisition. It’s about Arm’s larger strategy in the AI chip market.
Arm has recognized that to succeed in AI, it needs more than just its existing portfolio of IP. It needs the kind of high-speed data transfer technology that companies like Alphawave can provide.
Arm’s Next Move: Build or Buy SerDes Tech?
Arm may have walked away from the Alphawave deal, but its need for SerDes tech remains urgent. The company is now reportedly shifting to building the solution in-house.
It has begun hiring chip designers and discussing internal plans to launch its own processors with integrated SerDes.
This won’t be quick. Experts say developing competitive SerDes tech could take at least two years and a specialized team.
Meanwhile, rivals like Nvidia and Broadcom are already ahead.
A leaked email from December 2024 revealed Arm was even considering competing directly with its customers, including a potential trial with long-time partner Qualcomm. This shows just how serious Arm is about becoming a top AI chip player.
The AI Chip Market: A $60 Billion Opportunity
The AI chip market is expected to reach a staggering $60 billion by 2028, driven by the growing demand for high-performance hardware needed to run AI models at scale. Companies like Nvidia, Broadcom, and Marvell have already established themselves as leaders in this space. Nvidia’s GPUs are a key component of many AI applications, while Broadcom and Marvell have developed specialized technologies to support AI workloads.
Arm’s decision to pursue Alphawave and invest in SerDes technology shows that the company is preparing to compete in this highly lucrative market. But it also faces significant challenges. Not only does it need to develop or acquire SerDes technology, but it must also differentiate its chips in an increasingly crowded field.

Conclusion: The Battle for AI Chip Supremacy
Despite the Alphawave setback, Arm is not backing down. Its push into the AI chip market is still on track. The interest in SerDes shows Arm’s serious intent to compete with Nvidia, Broadcom, and Marvell.
Arm may build or buy the needed tech. Either way, it wants a bigger role in the AI chip race.
For investors, this is a big opportunity—but also a risky one. The custom AI chip market is heating up fast. The key advantage will go to those who control data transfer tech—the “plumbing” of AI. Arm’s journey is just beginning, and the road ahead will be tough but full of potential.d.
