Jupiter's atmosphere is about 25% helium. And then there's the other gas giants, and the sun itself (also about a quarter helium)
We risk running out of cheap helium. But if you are willing to pay infinite money there is near-infinite helium

The rocket equation is a very harsh mistress.
Maybe with a couple hundred more years of technological development...
Our moon itself is said to have ~1M tons of very valuable Helium-3 in surface deposits, but even that's nigh impossible to harvest commercially right now.
