Gold, often associated with jewelry and investment, plays a quiet yet indispensable role in the advanced electronics powering today's artificial intelligence boom. From high-performance chips and intricate connectors to the vast infrastructure of data centers, this precious metal is a critical component, according to analysis by Goldman Sachs.
The Unseen Value of Gold in Electronics
The unique properties of gold make it ideal for demanding electronic applications. It stands out as an exceptional electrical conductor and boasts high resistance to corrosion and oxidation. Furthermore, its malleability allows it to be formed into incredibly thin wires, films, and coatings without compromising its performance.
Historically, these characteristics have made gold essential for high-reliability systems, including early computers, telecommunications equipment, defense systems, and spacecraft. As electronics have become more compact and complex, gold's presence expanded across:
- High-end chips: Ensuring reliable electrical connections in microprocessors and memory.
- Connectors: Providing stable, corrosion-resistant links in devices like smartphones, laptops, and smartwatches.
- Sensors: Used in applications requiring durability and precise electronic sensing.
- Networking infrastructure: Supporting high-performance electronic systems and robust connections.
- Data centers: Integrated into the chips, connectors, and other electronic components that form the backbone of digital services and AI systems.
AI's Complicated Impact on Gold Demand
While the rapid expansion of AI technology fuels increased demand for advanced electronics and chips, this hasn't yet translated into a significant surge in gold consumption. Goldman Sachs reported annual technology demand for gold at 323 tonnes in 2025, a figure virtually unchanged from the previous year. The electronics sector accounts for approximately 80% of gold used in industrial applications.
This stable demand reflects a balance of opposing forces. The growing need for sophisticated AI chips naturally pushes gold demand higher. However, manufacturers are simultaneously striving to reduce their reliance on the expensive metal. Advances in miniaturization also mean that newer, smaller chips often require less gold or, in some cases, can be designed without it entirely.
Co-Packaged Optics: A New Avenue for Demand?
An emerging technology highlighted by Goldman Sachs, co-packaged optics (CPO), could open a new, albeit modest, source of gold demand. As AI models grow in complexity, the volume of data moving between processors and memory systems intensifies, straining conventional electronic connections.
CPO integrates optical communication components directly with processors, promising improved bandwidth, reduced data-transfer bottlenecks, and enhanced energy efficiency. Gold has potential applications within these systems, particularly in certain optical and photonic components and high-frequency electrodes. While CPO is still in its early adoption phase, widespread deployment in large AI data centers could create new demand.
Why Gold Remains Difficult to Replace
High gold prices have long incentivized manufacturers to reduce the quantity of gold used in electronics, leading to innovations like thinner bonding wires and coatings. However, Goldman Sachs notes that many of the relatively easy "thrifting" measures have already been implemented.
For high-end and safety-critical devices, manufacturers continue to prioritize reliability and longevity, making gold difficult to replace. For the foreseeable future, the burgeoning AI sector and ongoing efforts to minimize gold usage will remain competing forces, keeping the overall technology demand for the metal broadly stable.
