At the moment, there are a handful of countries that are selling bonds with slightly negative interest rates. Institutional investors are willing, in effect, to pay those countries to hold their money. In many cases, those investors hold those bonds not as investments but to hedge their risks. I am unaware of anyone that is offering to lend money to average people at a negative interest rate.
In theory, it could make sense to offer consumers loans at negative interest rates if the country was in a period of deflation that was expected to continue. As a practical matter, though, deflation tends to be a bad thing for the economy so if a real economy was in a semi-permanent deflationary spiral, it is unlikely that individual consumers would be good enough credit risks to make negative interest rates a thing.
Of course, I suppose it is possible that someone somewhere is offering a negative interest rate on a loan for a particular purpose as just a different way of offering a discount. A jeweler might offer, say, a -5% interest rate on a 3 year loan to purchase an engagement ring rather than discounting the price up front. That doesn't seem particularly likely-- the upfront discount would seem to be more attractive to the average consumer and easier for the retailer to explain-- but people and companies have been known to do unlikely things.
