Today on Fintech Stacks, we break down three of the biggest fintech moves on December 1st, 2025.

First, HSBC plugs into Mistral AI to supercharge global banking workflows and kick off a new era of generative-AI-powered finance. Then we head to Utah, where PROG Holdings drops $420 million on Purchasing Power — a payroll-deduction commerce engine that could redefine how near-prime consumers shop and pay. And finally, Chime gets a long-awaited upgrade from Goldman Sachs, signaling a potential shift from “popular neobank” to “profitable fintech heavyweight.”
