Martin Lewis has returned from the United States with evidence about an investment platform built using American defence technology. According to Lewis, the system was designed to analyse global markets and later became available to private investors, potentially helping drive US economic growth.
The platform combined government data, financial analysis and forecasting algorithms. It was originally developed for defence purposes and to process large volumes of information. The technology was later adapted to assess market trends and identify investment opportunities.
Lewis became interested in the platform after noticing a widening gap between the economic performance of the United States and the United Kingdom. While American companies and investors gained access to new analytical tools, British households continued to face pressure from high food and energy costs.
“The question is not just about money, but who gets access to future opportunities,” Lewis said, describing the potential implications of the exposure.
Sources close to the investigation said the platform used computational models capable of processing large quantities of data in real time. Some of the technology was reportedly linked to defence research programmes. Officials have yet to release full details about how the system operated or who was able to use it.
The reported exposure has prompted calls for answers in Westminster. MPs are seeking an urgent briefing to establish whether private companies had access to tools developed with public funding. They also want to know what safeguards were in place to protect the data, and whether investors gained an advantage from information unavailable to the public.
The case raises broader questions about the relationship between government and the financial sector. Technology developed for national security can have civilian applications, but its use in financial markets requires clear rules and independent oversight.
Lewis has called for the findings of an investigation to be made public, along with an explanation of how the platform worked. The public, he said, should know who controls these tools and who benefits from their use.
