A consonant string is meaning-neutral in every market on earth, which is precisely why this segment attracts consistent international demand.
Four characters, .com, no meaning attached. For a holding company, an investment vehicle, a private firm, or any business operating across languages where an English word would carry the wrong connotation somewhere, that neutrality is the whole point rather than a limitation.
The utility case holds as it always does. Four characters fits every place a name has to go, never gets truncated, never gets misheard into a different word, and has no plural or British spelling to defend.
Supply moves one direction only. Four-letter .com registrations were exhausted long ago and each year a few more settle into permanent use and stop trading.
