Probably.
There are certainly people who engage in nefarious bidding to drive up prices but in most cases that's not what is happening. If, when analysing sales, you start by thinking that a domain has intrinsic value, a sale like MindSeek.com for $40,000 might seem ridiculous... but that's a flaw in the way you're thinking about sales.
The majority of high price domain sales are sales to an end user. An end user is someone buying a domain name to use, not as an investment. Sure, for $40,000 you could buy a 3L .com like
nar.com that you could resell in future
but if your company is called MindSeek, why would you care about resale value? An end user sale is coveted by domain name investors
because the price is not dictated by the domain itself, but the value the end user gets from the domain.
.com is the default TLD, even today with thousands of alternative TLDs, .com still represents almost half of all domain name registrations. Owning the .com of your company name gives you de facto ownership over the name worldwide. If your company is called "MindSeek" and your website is "MindSeek.cool" then you are vulnerable to someone coming along and buying "MindSeek.com" which allows them (intentionally or unintentionally) to piggyback off of your brand building efforts.
Specific to MindSeek: google "MindSeek" and you'll find lots of companies using the name. There's mind-seek.com, mindseekai.com, mindseek.app and encoremindseek.net in the first page of results: that's multiple companies who would benefit from owning mindseek.com on the first page alone. Often, you can identify who bought the domain or make an educated guess. Which of these do you think might get $40,000 of value from owning the .com of their domain?
There is some degree of luck on the investors part here: did the investor in the domain know multiple companies would launch with the name "MindSeek"? Did they know that one of those companies would eventually be able to afford to spend $40,000 on a domain? No, they didn't know, but they likely had an investment thesis and a buyer profile in mind.
I won't provide a good strategy, but I will provide an example of a bad strategy:
A popular novice domain name investment strategy is to register a lot of keyword + location domain names, e.g: a novice might monitor new sales, see that
houstonpersonalinjurylawyer.com sold for $4,700 and decide to build a portfolio of similar names. The novice might go to Wikipedia, find the top 100 most populous U.S. cities and then register 100 [city]personalinjurylawyer.com domains. Each domain is $10/year = $1,000/year. The novice might theorise that if each domain is worth $4,700 and they have a sell through rate of 1% then they will profit $3,700 per year.
That's a terrible strategy because it doesn't consider
why the domain sold: who bought it? Why were they willing to spend $4,700? There are dozens of possibilities. For example, what if a company previously owned the domain houstonpersonalinjurylawyer.com and let it expire by mistake? Perhaps without access to the domain they couldn't access very valuable email communication, and that lack of access to could cause the business to shut down. The business owner would have a direct financial incentive to spend thousands of dollars on a domain for reasons that no other person on earth shares. The owner may have paid $4,700 out of desperation to rescue their business, not because [city]personalinjurylawyer.com has any intrinsic value.
Fundamentally, domains are not fungible. A domain that sells for $40,000 sold for $40,000 because it had $40,000 of value to the buyer. The reason for the $40,000 of value to the buyer could be completely unique to that buyer, or it could be indicative of a broader trend that an investor can use to help inform their investments.
