If by "split king", you mean two TwinXL beds that you place next to each other without touching, then yes this will work great. But of course you'll have a gap between the beds. If instead you mean two TwinXL mattresses on the same King size bed that either touch or that are enclosed in the same cover/protector, then the benefit will be minimal. Motion still transfers both through the bed frame and through the joint surface between both mattresses. It'll likely improve things a little bit, but I wouldn't hold much hope that it'll make a dramatic difference. Answer from Grim-Sleeper on reddit.com

r/Mattress on Reddit: Will a split king keep me from getting woken up by my spouse's movements at night?
May 17, 2023 -
Fuller description of sleep issues here: https://www.reddit.com/r/sleep/comments/13k231y/i_sleep_better_when_im_in_a_separate_bed_from_my/
In short, over the last several months, I've been remembering getting woken up by my spouse more, and at the same time I was getting more and more tired during the day. Upgrading from a queen to a king mattress helped a little bit, but the issue still persists. Sleeping in separate beds is not an option, because my spouse views our time together in bed sleeping as valuable intimacy in their life.
I've tried several things to alleviate me getting woken up by my spouse, with some success, but I'm still tired during the day.
It seems the only option left is to get a split king mattress (which my spouse says will still count as sleeping in the same bed for their needs) and hoping that completely isolates me from my spouse's movements.
Will a split king mattress accomplish this? Or will it just open up a different style or flavor of getting woken up by my spouse's movements at night?

Splitting your mattress into two TwinXL/Split King mattresses will be a good start at gaining your independence while maneuvering towards a bit more motion isolation. Along with this, selecting the right style and model of mattress that focuses towards motion isolation will be key. In regards to the comments on having a space between the two mattresses. A simple foam bridge may assist in eliminating this from being an issue. Have you been looking into any specific models for your new mattress selection?
