Looks like it's available under the fairly permissive LGPL licence - https://doc-snapshots.qt.io/qt6-dev/licensing.html

It's worth noting that there are specific add-on modules that are only available under the GPLv3 license. Qt6 doesn't have all of them yet, and they (supposedly) will be coming in the 6.1-6.2 releases.

Qt6: https://doc.qt.io/qt-6/qtmodules.html#gpl-licensed-addons

For commercial purposes it is actually very expensive.

The company behind Qt has been getting very passive-aggressive in the last 1..2 years about using the LGPL version for commercial projects. They didn't shut it down (yet?) but they're definitely not happy about it. Personally I wouldn't consider Qt for future projects because the writing is on the wall.
