Also seen as 「ハイきたぁ～！」.

Maybe it's used among young people.

It seems to express the idea that you have achieved your expectations, or
something like that.

I hope someone can explain it better.

question
expressions
What does 「ハイきた。」 mean?
It's a colloquial form of `はい、来た` as in "yep, (it's) come" or "yep, (it's)
arrived".

The way it seemed to be used when I searched blogs (when written as `ハイきた` and
other similar variants) was mainly "just in!", "read all about it!", "scoop!"
etc. It was often put as the title in blog posts or just before images etc for
dramatic effect.

It also looks like it can have a different meaning when written as `ハイきたぁ～！`
and similar, taking the meaning "yep, the time has come!", "yes, it's that
time again!", "oh no (not again)!" etc in the context of exams et al.

「はい、きたぁ~」 is fairly close to "there we go" in English.

「はい、きたぁ~」 can be used for positive and negative events. 「はい、きたぁ~」being used
for pleasant events is more frequent.

One nuance is that when you use 「はい、きたぁ~」 for negative event it would probably
correspond more to "there we go again", then to "there we go".

Hope it helps.
