The claim has two parts: that Jupiter listed SpaceX-linked pre-IPO shares as low as $185, and that Jupiter offers structured instruments backed 1:1 by SPV exposure to provide price exposure to SpaceX. I could not validate the provided X post because fetching https://x.com/x/status/2041592989274009802 failed. I also attempted X search, which returned an API error, and web searches did not surface a fetchable authoritative Jupiter page or announcement. The only partially relevant corroboration found was the WSJ result titled 'You Can Own Elon Musk's SpaceX. But at What Price? - WSJ', whose snippet mentions a $185 private share price, but that does not by itself confirm Jupiter's product structure or listing. Because the central Jupiter-specific evidence is missing, the overall claim remains unverified.
