As fraudsters adopt AI tools, payment providers and retailers are deploying increasingly sophisticated machine learning to protect transactions. Neither side is winning decisively, but the data advantage currently sits with the defenders.
AI-powered fraud in early 2026 isn't the high-volume, low-effort credential stuffing of five years ago. It's fewer attacks, smarter attacks, and attacks that are genuinely harder to distinguish from legitimate behaviour. The industry isn't losing — but it's not comfortable either.
Klarna floated on the NYSE in September 2025, raising $1.37 billion and opening 30% above its offer price. The IPO narrative was built substantially around AI as a commercial multiplier. Public markets believed enough of it. The implications for UK commerce and fintech extend well beyond Klarna's own balance sheet.
Through 2025, every major incumbent in global payments shipped a version of the same infrastructure: tokenised rails for AI agents to complete purchases autonomously. The convergence is less a market signal than a regulatory gap being filled by private hands.
The EU's AI regulation is coming into force in phases. The UK hasn't followed suit — but UK retailers with EU exposure or AI vendor contracts are more implicated than the 'not our problem' reading suggests.
Pay360 2025 at ExCeL London landed one month before Mastercard's Agent Pay announcement. The payments industry already knew where it was heading. The mood was focused rather than euphoric, which felt about right.
UK fintech investment hit £5.7bn in H1 2024, nearly three times the same period in 2023. Revolut, Monzo, and Klarna are all using AI at scale. But the practical applications are less about consumer experience and more about the unglamorous infrastructure of financial services.
Pay360 2024 brought the UK payments community to ExCeL London. AI was on the agenda — but the conversation was less about transformation and more about where AI is actually earning its keep in the plumbing of financial infrastructure. Which, it turns out, is everywhere.
