TL;DR
Arm was sold to Softbank in 2016 amid Brexit uncertainty, raising questions about UK tech sovereignty. Now, Arm’s move into chip manufacturing and Apple’s potential CPU independence are key developments. The situation remains complex and evolving.
Arm, the UK-based semiconductor designer, is now reportedly considering launching its own CPU chips, a move that could reshape its role in the industry and impact major players like Apple. This development follows Arm’s historic sale to Softbank in 2016, which has been subject to significant debate regarding UK technological independence and national security implications.
Recent industry discussions, notably from the ‘Supply Chained’ podcast hosted by Tim Culpan and Jon Y, highlight that Arm’s decision to develop its own chips marks a shift from its previous business model, which primarily involved licensing its architecture to other manufacturers. This move is seen as potentially undermining its immunity from takeover by large chip firms such as Intel, Nvidia, or Qualcomm, as Arm would now be competing directly in chip manufacturing.
Arm’s sale to Softbank in 2016 for approximately £24 billion was controversial, especially in the UK. Critics like Hermann Hauser, co-founder of Acorn Computers, expressed concern over the loss of a key British technology asset. The UK government’s approval was influenced by the post-Brexit economic climate, with Prime Minister Theresa May framing the deal as a positive sign for UK industry despite the broader political uncertainty.
Legal constraints in the UK limited government intervention, as authorities only have grounds to block takeovers over competition or national security issues. The government’s stance was largely supportive, emphasizing the deal’s potential benefits for the UK economy amid Brexit turmoil. However, the sale raised questions about the UK’s control over its vital technology assets and future strategic independence.
Why It Matters
This matters because Arm’s shift toward chip manufacturing could challenge its previous status as a neutral licensor, potentially altering the competitive landscape. For the UK, the sale and subsequent strategic moves highlight ongoing concerns about technological sovereignty and the country’s role in global tech innovation. For Apple, the discussion about ditching Arm’s ISA in favor of its own CPU architecture could accelerate if Arm’s new direction proves successful, impacting the broader industry ecosystem.

Background
Arm’s history dates back to its flotation on the London Stock Exchange and Nasdaq in 1998. Its sale to Softbank in 2016 was driven by Softbank’s desire to expand into the semiconductor industry, but it also sparked debates about UK asset protection. The Brexit vote in June 2016 created a climate of economic uncertainty, influencing government decisions on foreign investments. Prior to this, Arm’s architecture had become the dominant standard in mobile and embedded devices, making its ownership and future direction highly consequential.

What Remains Unclear
It remains unclear how successful Arm’s move into chip manufacturing will be and whether it will indeed challenge existing industry players. The potential impact on Apple’s CPU strategy, including the possibility of developing its own ISA, is still speculative. Further industry developments and official statements are awaited to clarify these strategic shifts.

Key Questions
Why did the UK government allow the sale of Arm to Softbank?
The UK government approved the sale primarily due to legal constraints—intervention was limited to competition or national security concerns. At the time, Brexit uncertainty and the legal framework influenced the decision, with officials emphasizing economic benefits.
What are the implications of Arm developing its own chips?
If Arm starts manufacturing chips, it could compete directly with existing semiconductor giants, potentially disrupting licensing models and industry hierarchies. This shift might also influence how companies like Apple design their processors.
Could Apple develop its own CPU ISA instead of using Arm?
It is a possibility discussed in industry circles. Apple has already been developing its own silicon, and moving away from Arm’s architecture could give it more control over its hardware, but such a move would entail significant technical and strategic challenges.
What does this mean for UK’s tech independence?
The sale and Arm’s evolving strategy highlight ongoing concerns about UK’s control over critical technology assets. Greater industry independence would require new policies or strategic initiatives to safeguard national interests.
