No limit holdem has been essentially solved. Pluribus & co not withstanding, you just haven't heard of it because the people who have solved it are busy printing money in online poker (yes, I know they try to detect bots, and no, they can't detect them all). With stakes this high, academic progress lags the 'actual' state-of-the-art by years.

IIRC it's "solved" for heads up but not really multiway like 3+ to the flop. I believe in a recent Bart Hanson Youtube he points out that mutltiway is not solved.
oh wait, Google showed me this:

> Machines have raised the stakes once again. A superhuman poker-playing bot called Pluribus has beaten top human professionals at six-player no-limit Texas hold’em poker, the most popular variant of the game. It is the first time that an artificial-intelligence (AI) program has beaten elite human players at a game with more than two players

It's not solved for multiway in the sense that the optimal move in each situation isn't known, but there are AIs like Pluribus that have superhuman performance.
Superhuman performance in a very constrained version of no-limit hold'em
Those constraints don't seem that strong to me. The algorithm could've just been retrained with different stack sizes if it ended up making a big enough difference.
