The episode connects ambitious AI infrastructure plans and uranium exploration catalysts with governance, rates and valuation risks facing small-cap investors.
- 1Luke Sartain presents Narwhal Labs as a sovereign UK AI and communications utility less dependent on US frontier-model providers.
- 2Rory Harding outlines Arkle Resources’ Namibia uranium programme, with pending assays and expanded drilling central to its next catalysts.
- 3The hosts weigh company-specific news against higher bond yields, inflation, critical-minerals demand and the need for productive infrastructure.

Luke Sartain explains how Narwhal Labs aims to combine sovereign AI, communications services and satellite infrastructure into a utility platform.
The brief
Phil Carroll and Kevin Hornsby open with the week’s AI sell-off, existential-risk debate and political headlines before turning to the small-cap themes shaping their market view.
Luke Sartain describes Narwhal Labs’ plan for a sovereign UK AI communications stack, combining agents, secure data and usage-based services while reducing reliance on US providers.
The AI discussion expands into satellite infrastructure, utility economics and the social consequences of AGI, including employment, geopolitics, energy and medical research.
Rory Harding details Arkle Resources’ ULG uranium target in Namibia, where drilling, geological continuity and pending assays could define the next stage of exploration.
The hosts then survey governance, critical minerals, healthcare technology, interest rates and physical-asset themes, arguing that infrastructure demand may matter more than market fashion.
