How can I possibly know when to exit a venture capital etf?

I sold off my Palantir ( not at the ath dang it) and bought into VCX at $86 and it's done very well. Mostly bought because my work was now moving to Claude from Palantir and Anthropic was getting hyped as being a better product. SpaceX is in it, IPO upcoming and that's being pegged as exit for early investors. Open AI is being sued multiple ways. Now I'm not saying my public traded company i work for cooks the books, but i know they're creative on what losses or gains get reported for what quarters. Admittedly I don't know a bunch about the fund beyond knowing a bit about the individual holdings and I'm holding strictly on vibes because I feel like they're is no way to know whats happening behind the curtain here with these companies and this fund. How do I avoid becoming exit liquidity?
