As artificial intelligence reshapes global chipmaking, the UK's strength in design, materials and research is being tested by a longstanding challenge: turning technological breakthroughs into scalable commercial products.

At Hon Hai Tech Day 2026 (HHTD 26), Foxconn showcased the Nvidia DSX POD containerized solution. By leveraging factory pre-building, electromechanical integration, and pre-testing, Foxconn integrates computing racks, networking equipment, power distribution, and liquid cooling systems into rapidly deployable computing units. This approach assists Nvidia in transforming its AI computing platform into a modular data center architecture capable of mass production and on-site delivery.

Marvell announced on November 2 that it has entered into a definitive agreement to acquire Lumentum Holdings in an all-stock transaction valued at nearly US$115 billion. Subject to regulatory approval, the transaction is expected to close in the first half of 2028.

Qualcomm's weakening smartphone business is accelerating its transformation into an AI infrastructure supplier, with custom accelerators, server CPUs, and optical connectivity emerging as growth priorities. Following a 26% annual decline in handset chip revenue in fiscal 4Q26, the US chipmaker is targeting US$5 billion in data center revenue in fiscal 2027 and US$15 billion by fiscal 2029. The question is whether these businesses can scale quickly enough to offset pressures in its traditional market.

AI data centers are accelerating demand for high-speed optical communications, extending competition in the optical transceiver market beyond chips and module manufacturing to critical upstream materials. Indium phosphide (InP), a key substrate for high-speed optical lasers and optoelectronic devices, is increasingly sought after as 800G and 1.6T transceivers gain traction. With capacity expansion requiring time and product qualification presenting technical hurdles, securing InP wafer supplies has become a strategic priority for optical communications companies.

ASML and TSMC announced plans in September 2026, ahead of the SPIE BACUS symposium, to advance high-numerical-aperture extreme ultraviolet (High NA EUV) lithography by replacing the decades-old 6-inch photomask format with larger 12-inch masks. TSMC plans to introduce High NA EUV into advanced-node volume production from 2030, establish a 12-inch mask pilot line and begin production-line and ecosystem qualification by 2031, and achieve full readiness for 12-inch-mask High NA EUV systems supporting advanced-node manufacturing by 2033.

Modern cryptography relies heavily on trapdoor one-way functions: mathematical operations that are easy to perform but difficult to reverse without additional information. Quantum computing and advances in artificial intelligence, however, are raising questions about how long this protection can last.

Iluvatar CoreX has reported benchmark results showing its Tiangai 300 AI accelerator outperforming Nvidia's H200 on selected metrics, drawing renewed attention to China's progress in developing domestic alternatives to high-end GPUs. Yet the broader competition extends beyond raw processing power, as Chinese chipmakers seek to narrow the gap with leading international AI computing platforms through chip design, software optimisation and system integration.

Samsung Electronics has never had more capital at its disposal. The company reported operating profit of KRW89.5 trillion (approx. US$67 billion) in the second quarter of 2026 and KRW107.4 trillion in the third, when its operating margin reached approximately 55%. Samsung became the first technology company worldwide to post quarterly operating profit exceeding KRW100 trillion. The company is benefiting enormously from the memory boom, but its dependence on the industry has also deepened.

Samsung Electronics' contract chipmaking business spent years struggling to fill its factories. On its third-quarter earnings call, the company said that by 2027, demand will exceed capacity across all its nodes below 8nm, which it expects to run at over 100% utilization.

High-profile breaches caused by AI agents from frontier labs are leading to public alarm over what AI means for the future of cybersecurity. However, Taivo Pungas, chief intelligence officer of agentic procurement platform Pactum, said that AI development is becoming a cybersecurity boon and could even be a boost for software as a service (SaaS) products.

The outlook for AI neocloud providers has sparked a clash between Tesla CEO Elon Musk, who warned that more than 200 such companies could face large-scale failures or consolidation, and Nvidia CEO Jensen Huang, who said during an interview at the GTC Berlin conference that demand for neocloud services has exceeded expectations and current funding shortages will eventually be resolved.

Arm is expanding its business model from licensing Neoverse core IP and compute subsystem (CSS) technologies to selling finished server CPUs for artificial general intelligence (AGI) applications. Meta is a co-developer and primary customer, while OpenAI also plans to adopt the products. Customers can purchase processors directly, reducing the time and cost required to develop and deploy their own chips, while Arm can increase its chip sales revenue.

Millimeter-wave (mmWave) technology was previously used mainly in military and aerospace applications, where costs were extremely high. Now, as high-frequency communications and non-terrestrial network (NTN) technologies gain momentum, new opportunities are opening up across the communications industry.

The Biological Computing Co. (TBC), a San Francisco startup that grows living neurons in its lab to find ways to make AI models more efficient, launched its first publicly available product on October 30: mischief 1, an image-to-video model the company says generates video five times faster than the open-weight model it is built on. The release moves TBC's technology from an early-access program to self-serve developer marketplaces and puts a price on the company's argument that biology can be a source of AI efficiency distinct from the standard optimization toolkit.
