My bank has both commercial & cultural reasons not to sell my ID & transaction history. They might still do it anyways, but it's at least plausible that they wouldn't, if only due to the harm to their reputation if it ends up in the papers.
If we want to monetize insights from aggregated data, we'd do it in-house and offer you better products. Example: Why sell your mortgage readiness data to some broker when we could source competitive mortgage offers and present them directly to you? Keep you in our ecosystem, add value to your experience, and build a revenue stream that doesn't destroy the core product.
The wealth space is crowded. Companies that burn user trust get exposed fast and die faster. The only sustainable path is treating your data like it belongs to you and not us. Any company here who doesn't get that is building on quicksand and I'd be very surprised to hear any of the larger players engaging in those practices but maybe I'm naive.
Either way, it's why we're a Fiduciary and that blankets the entire product suite.

That article is about JPMorgan being able to charge Plaid or other providers for the middleman access. They used to be operating almost for free, now Plaid has to pay for access the same way companies like mine pay Plaid.
Plaid does in fact sell your data, but they ask for permission first. So does JPMC, for that matter: https://media.chase.com/news/chase-launches-chase-media-solu...
Here is the quote if you're too lazy to read this one too:
Does Plaid sell my financial data for advertising or marketing purposes?
No, we do not sell your financial data to third parties for marketing or advertising purposes.
Plaid only shares your data to power the services and products that you choose or to protect you and the Plaid network from fraud.
Plaid was founded on the principle that you have a right to your financial information and we are focused on providing products that allow you to safely and conveniently access your data and harness the power of Plaid’s secure financial network.
As Plaid develops more products and services, you may ask Plaid to share your information in ways that benefit you and that you control.
SimpleFIN¹ looks compelling. Actual Budget can use that and it seems to work more like a privacy-oriented Plaid. But, now you need to trust a much smaller player. Really, I wish this were all standardized with strict privacy requirements.
At a certain point paranoia gives way to practicality.
Sell the data to whom?
"it would be astonishing if they _didn't_ sell my data."
If the "who" was answered with "... to Kim Jong Un, glorious leader of the DPRK" you might raise a brow. That is probably not what they meant.
Maybe the author meant "... to the legal buyer of the new company, as part of the content of the company"? Maybe they meant "... to anyone willing to pay a price, legally or illegally"?
I wondered what scenario the author had in mind. It's a reasonable question. To me, the implications are quite different. You might of course disagree.
I’ve worked in marketing enough to know that all sorts of less-interesting data gets bought and sold, yet alone financial data, but even if limiting the context to “for marketing purposes” I wouldn’t know, and would be interested in being told, which companies actually are buying that sort of financial information.
And as the user has now explained in a comment further down the thread, they weren’t limiting their curiosity to just marketing profiling so there’s an even wider scope to their question.
But hey, easier to just call them naive than to give them the benefit of the doubt and engage constructively.
