I think the thing that makes it hard to confirm is that for most every other club the owners are either one specific rich individual (eg Abramovich) or a group of wealthy people (eg Arsenal), and their ownership is something of an indulgence or distraction alongside their normal business investments. Whereas we aren't owned by Guo Guangchang (whose personal wealth is supposedly around $4bn); we're very much a Fosun property, and with a conglomerate like Fosun it's a lot harder to nail down anything more than a ballpark figure—you can look at market cap for example, but a) there are different figures for that in different places (I've seen everything from $24bn to $12bn), and b) market cap isn't a good indicator of a company's actual day-to-day financial muscle. We know that Fosun's annual revenues are in the single billions of dollars, though, around $3-4bn per year, so they do have considerable muscle without having to even think about loans or liquidating assets to raise cash for spending.
Realistically, long-term and today, we're probably on a par with a club like Chelsea, which Abramovich doesn't have to subsidize much at all these days, as opposed to being constantly pumped full of money directly and indirectly like Sheikh Mansour's Manchester City (although just like Mansour, Fosun's interests in Wolves will be as much about state soft power projection as it is personal prestige or pure investment).
