Blockchain transaction change output I'm very new to this.
It’s hard to know for sure, but what’s most likely the case with the below transaction:


Someone sent 25.99 bitcoin to another person/organization
Someone sent 1 bitcoin to another person/organization
Someone sent 26.99 bitcoin to another person/organization
You cannot say for sure.
The three options are potentially true.
However, many clients build transactions with the change output as the last output.
So, following this convention, I would say option 2 is the most likely.
