Taking a page from Elon Musk's other big company, Tesla, newly public rocket maker SpaceX ‌has opened an online venue for investors to ask questions ahead of a call about results that is expected to feature Musk. Users can submit questions ​and vote on which ones will be answered, creating a list ranked by popularity. The eclectic mix of questions comes after SpaceX set aside roughly 30% of its IPO shares for retail investors, one ​of ​the largest individual investor allocations in a major U.S. listing. When the company's AI business could begin paying for itself was question number 183 as of late on Friday afternoon. Most retail investors were optimistic about SpaceX's ​future, but one user questioned ​whether Musk's own long-term vision made investing worthwhile.
