At the moment Bitcoin cash is trading around 115 USD. Which means it would need to make around a x17 from it's current price to reach the 2000 $ mark per coin. So a huge growth is needed in order to reach this high price so i am not sure if this is realistic at all. That being said the all time high of Bitcoin Cash was at around 3900 USD so it definitely is not impossible to reach 2000 $ in 2026 in my opinion. A lot of stuff can happen in 4 years after all.
It all depends on the overall market movement. I don't really see Bitcoin cash making a huge run by itself to be honest because there are just so much other projects out there that seem to be more innovative and future proof in my opinion.
