2026 GZERO Summit in London

On 8 October 2026, LSEG and Eurasia Group hosted the GZERO Summit in London for the second time, convening senior leaders from across the public and private sectors to explore the geopolitical forces shaping markets.

Against a backdrop of pivotal European elections and a closely watched US midterm cycle, discussions examined the evolving political, economic and strategic landscape, spanning:

Competitiveness and trade
Technology and innovation
Politics and governance
Defence and security

The Summit explored the implications of these shifts for business and markets, with particular focus on transatlantic relations, energy security, global trade and the growing impact of AI on economies, markets and society.

Dominic Barton, Strategic Counsellor, Eurasia Group and Chairman, Rio Tinto

Hear Emily Prince discuss how a customer-centric, end-to-end approach can unlock new ways of building products and accelerate innovation.

AI has the capability to dramatically decreasethat information premium that smaller companiesare paying forbecause you could, through AImake the analysis of thousands of companiesand papers and perspectives and so onmuch more efficient.I'd love to say cheaperI don't think we know that yet, rightbut at least much more efficient.And all of a sudden, the absolute rich diversityof the economic landscape of Europe could be much more visibleand much more attractive.So I think it could compress basically the cost of complexityand Europe should really engage in AI as in analysing market kind of AIto get basically that capital coming their way.

Hear Corentine Poilvet-Clédière discuss how AI can reduce the complexity of analysing smaller companies, making Europe’s diverse opportunities more visible and attracting capital to the continent.

Hear Corentine Poilvet-Clédière discuss how enabling investors to discover, analyse and hold small- and mid-cap companies can help unlock opportunity across European markets.

How much progress Europe makes will be a function of its political will. As it builds scale, resilience and competitiveness. Europe needs to avoid the false choice between resilience and openness. AI has the capability to dramatically decrease that information premium that smaller companies are paying for. I've resisted quite a lot this temptation into is AI about efficiency or is it about value because I think what that speaks to is that there's a divorce between efficiency and value, like. Given particularly the compute gap between the U.S. and China given where they are, where they stand at the frontier vis-a-vis the United States, has been a very smart strategy. The paradox of the moment we’re in that it is both, I think, the most dangerous moment of our lifetimes but also the most transformational.

Explore highlights from the GZERO Summit, where leaders examined resilience, AI and the forces reshaping Europe and global markets.

AI as a general purpose technology they don't come along that often. We're lucky to be living at a time when we will get the benefits of this and if we get that right I think it'll be transformational not just economically but also for society and really raise the floor for humanity as well.

Rishi Sunak reflects on the transformational potential of AI and the opportunities it could create for economies and society.

From the kind of perch I have. Anthropic and Microsoft in particular. The things that have really struck me are the following. One is just how quickly the technology is spreading. And if you look at how long it took kind of previous big technologies to reach 100 million people, I think that's quite helpful. So it took 70 years for the telephone to reach 100 million people electricity. It took 50 years. Then fast forward a bit the PC, it took 15 years. The internet? It took seven years. Right. ChatGPT two months. Right. So this is clearly something that's happening much faster than we've experienced before. And then the second thing is how quickly the technology itself is improving. And it's hard for us to kind of grapple with exponential growth. I always find we had to get a crash course in it during Covid, but effectively you should think about the capability of these models doubling consistently every six months. Right. That has now been happening for some years. And I have to say, I always thought that would slow down. But if anything it is sped up. And that is, you know, you think about something doubling every now potentially four months, not even six months before you know it. Something quite significant is happening.

Rishi Sunak explores the accelerating pace of AI adoption and advancement, and what sets this technological shift apart.
