LSEG will participate in the design phase of Lumen Sovereign, a UK sovereign AI model trained on domestic infrastructure, and support the Spärck AI Scholarship, a government-funded programme developing top UK AI talent at master’s level. These key initiatives aim to accelerate responsible AI adoption while strengthening the UK’s domestic technology capability and talent pipeline – two key pillars of the Government’s AI Opportunities Action Plan.
These announcements mark an important step in turning the UK’s AI ambition into practical outcomes for industry, workers and the wider economy. As a global organisation with headquarters in London, we see the UK as playing an important role in shaping the global AI ecosystem, with strong foundations in data, financial services and innovation. We are committed to helping to scale trusted, responsible AI adoption both in the UK and across the global markets we serve.
Building sovereign AI capability through trusted partnerships
LSEG is pleased to join a coalition of industry leaders to co-design Lumen Sovereign, Britain’s first fully sovereign frontier AI model. We support the UK building strategic domestic technology capability, while maintaining global interoperability, openness and choice. Firms should be able to choose the technology providers that best meet their needs, without undue restrictions, to support innovation, competition and resilience.
This collaboration demonstrates how our AI strategy is enabling trusted, scalable AI adoption in highly regulated environments. Through a memorandum of understanding, LSEG will draw on our leadership in trusted data, financial markets infrastructure and responsible AI to work with Cosine to define the use cases, security requirements and governance standards the model must meet from the outset.
Supporting the next generation of AI talent
LSEG has also joined a new cohort of industry partners, identified by the Government as leading firms to develop the next generation of top AI talent. From September 2026, LSEG will support the Spärck AI Scholarship, providing leading AI scholars across the UK with mentorship and placements to help translate academic expertise into real-world impact and equip emerging talent with the practical skills and experience needed to drive AI adoption in complex, regulated environments. This reflects LSEG’s broader commitment to developing the capabilities and expertise that underpin responsible, large-scale AI adoption.
A trusted partner in the UK’s AI ambitions
LSEG operates at the heart of global financial markets, providing the data, analytics and infrastructure that underpin decision-making for firms, regulators and public authorities worldwide. We are uniquely positioned to support the UK’s ambition to become a leading AI-enabled economy. As a trusted partner to the markets we serve, we are contributing practical insights into how AI can be deployed at scale in complex, regulated environments.
LSEG’s approach to AI
At LSEG, our approach to AI is grounded in one simple principle: trusted data is the foundation of trusted AI.
Our AI strategy – LSEG Everywhere – is built on three pillars:
1. Trusted data
We deliver high-quality, structured and governed data designed specifically for AI use. Our datasets provide the context, accuracy and provenance required for AI systems to operate reliably in financial markets.
2. Transformative products
We are embedding AI into our products to help customers work faster and make better decisions. From natural language tools that simplify complex analysis to AI-enabled insights within our platforms, we are reimagining financial workflows.
3. Intelligent enterprise
We are applying AI across our own operations to improve efficiency, resilience and customer experience, from automating data extraction to enhancing client support.
Our approach ensures that AI delivers real value while maintaining the highest standards of accuracy, transparency and control.
