Similar to capital moving between the world's financial markets and ending up in whatever country investors think will offer the best return, money is definitely flowing into TBRs at the moment. As soon as the pandemic started, auction prices for 2 word .com's skyrocketed, then 1 word .net .org .co and pronounceable 5L .com, then more recently 4L .com and 3L .net .org .co went way up. At this point the only .com auction prices that haven't gone through the roof are 5N and 6N and I'm sure they will soon. This is why people like me have turned our attention to .ca!
People now view domains as appreciating digital assets. Their value is not just based on the chance an end user comes along willing to pay big money, it's also based on the fact many people believe these assets will be worth more next year and the year after. If you can buy a domain, have a chance of selling it for 10x your money to an end user, but if not sell it to another "domainer" in a few years for 2x it makes sense to buy. Is this a bubble? Very possibly. One thing is for sure tho... all the domains you currently own are worth more now than they were last year, but it will become harder and harder to add quality names to your portfolio at a reasonable price. Just wait until WallStreetBets / Tai Lopez / Warrior Forum etc start to talk about domains as a lucrative sidehustle or even a way to get rich quick.
