/ SILVER NOTES

Where the silver actually sits in a data centre.

The server does not need a silver lining in the literary sense. The April 2026 World Silver Survey documents silver in chip packaging, connectors and power modules, with roles in signal integrity and heat transfer. [S1]

Why use silver?

For this 17 September 2026 research snapshot, the conductivity reference gives silver about 63 million siemens per metre, against about 59 million for copper: roughly 7 percent higher electrical conductivity. Thermal conductivity is about 429 watts per metre kelvin for silver and 401 for copper. Silver is the most electrically conductive metal; USGS also identifies electrical conductivity among its defining properties in its 2026 summary. [S14] [S7]

Those reference values explain the material's appeal, but do not measure the amount installed in a machine. In the April 2026 survey, the applications are specific: packaging, connections, power equipment and thermal interfaces. Reading a conductivity table as a silver content table would skip the measurement that matters for demand. The published properties support an explanation of why silver is used, not a calculation of ounces per processor. [S1] [S14]

Connections, packaging and heat

The April 2026 survey links material uses to electrical performance and heat management. Its account is explicit: “Silver-based pastes preserve signal integrity, while thermal interface materials fill microscopic gaps between chips and heat sinks.” It also identifies switches, breakers, grid equipment and contacts. The documented demand therefore includes equipment that supplies and manages power, as well as components associated with computing. [S1]

Oxford Economics, in research released by the Silver Institute on 9 December 2025, identifies connectors, circuits, die attach in servers and GPUs, and heat sinks. That is a useful map of applications. It is not an inventory of the silver inside a particular server, and it does not establish that every product uses the same amount. The December 2025 report supplies no quantity per server, per GPU or per megawatt. [S2] [S3]

Capacity growth is not a silver measurement

The Oxford Economics research of December 2025 describes global IT power capacity growing 53 times, from 0.93 gigawatts in 2000 to nearly 50 gigawatts in 2025. This establishes the scale of the capacity expansion in that report. It does not establish that silver demand grew 53 times, because the report does not provide a matching series of silver quantities. [S2] [S3]

For the same reason, the December 2025 capacity figures cannot be multiplied by an assumed silver loading and presented as the report's demand estimate. Capacity and metal consumption answer different questions here. One is supplied by the source; the other would require information that it does not publish. Keeping the two apart leaves the documented growth intact without attaching an unsupported metal total to it. [S3]

The one quantified primary estimate

The April 2026 World Silver Survey expects data centre offtake “to exceed 10% of electrical and electronics demand next year”. This is the quantified primary estimate identified in the research reviewed on 17 September 2026. It is a forecast share of a larger demand category, rather than a measured quantity inside a machine. [S1]

Kitco's commentary dated 20 August 2026 interprets that share as more than 42 million ounces, using the survey's 2026 electrical and electronics forecast of 422.9 million ounces. That is Kitco's reading. The words “next year” in an April 2026 publication may mean 2027. The wording is ambiguous, so the calculation should not be relabelled as a confirmed 2026 data centre total. [S1] [S15]

For scale, 42 million ounces would be about 3.8 percent of the survey's 2026 total demand forecast of 1,112.6 million ounces. This calculation illustrates the size of that scenario; it does not resolve the forecast year or turn a threshold into an exact annual total. [S1] [S15]

No credible per server or per chip number

As of the 17 September 2026 review, no credible per server, per chip or per GPU quantity was identified in these sources. The December 2025 Oxford report lists applications without unit quantities, while the April 2026 survey gives an aggregate forecast share. Neither supports a universal hardware loading. [S1] [S3]

Dealer blog figures therefore need caution: an application list and a capacity forecast cannot substantiate their missing unit measurements. For this September 2026 account, the defensible stopping point is the documented uses and the qualified aggregate estimate. A more precise answer would need a primary measurement, a defined equipment scope and a stated year. [S1] [S3]
