SpaceX is poised to receive billions of dollars in passive investment flows after its rapid inclusion in the Nasdaq-100 index, while Wall Street brokerages have initiated coverage of the aerospace and satellite company with overwhelmingly positive ratings, according to a Reuters report.The Elon Musk-led company was added to the tech-heavy Nasdaq-100 on Tuesday, less than a month after making its stock market debut on June 12. This swift inclusion follows Nasdaq's revised eligibility rules for newly listed companies, making SpaceX one of the fastest firms to enter the widely tracked benchmark.The index inclusion is expected to create fresh demand for SpaceX shares, as exchange-traded funds (ETFs) and index funds that track the Nasdaq-100 rebalance their portfolios to reflect the benchmark's updated composition.Despite the milestone, SpaceX shares fell 5.4% on Tuesday, mirroring weakness across high-growth technology stocks, including Micron Technology, amid investor concerns over whether the artificial intelligence-driven rally can be sustained.According to LSEG data cited by Reuters, SpaceX carries a weighting of about 1.34% in the Nasdaq-100. This is significantly lower than heavyweight constituents such as Nvidia and Apple, as Nasdaq assigns weights based on companies' public free float.Reuters reported that J.P. Morgan estimates the company's inclusion could generate approximately $4.3 billion in passive inflows. More than $587 billion in assets are benchmarked against the Nasdaq-100, including the popular Invesco QQQ ETF, which will now add SpaceX to its holdings.Brokerages initiate coverage with optimistic outlookMore than a dozen investment banks and brokerages, including IPO underwriters Morgan Stanley, Goldman Sachs and J.P. Morgan, launched formal coverage of SpaceX following its listing.According to Reuters, analysts broadly view the company as well positioned to capitalize on long-term opportunities across space transportation, satellite connectivity and artificial intelligence.A major pillar of Wall Street's optimism is Starship, SpaceX's next-generation fully reusable rocket. Analysts expect the vehicle to become the company's primary long-term growth engine if commercial deployment scales successfully.Forecasts for Starship launches vary across brokerages. J.P. Morgan projects roughly 5,000 launches annually by 2031, Wells Fargo estimates around 4,600, Bernstein expects about 3,500, while UBS forecasts more than 1,500 launches, depending on the pace of technological progress and reusability.Among the most optimistic firms, Raymond James assigned a Wall Street-high price target of $800 per share, compared with the IPO price of $135.Not all analysts share the bullish outlook, however. Reuters reported that MoffettNathanson, KeyBanc and Argus Research have neutral-equivalent ratings on the stock, while CFRA is the only brokerage with a sell rating and a price target of $115.AI ambitions add to growth narrativeBeyond its space business, investors are increasingly valuing SpaceX for its artificial intelligence ambitions.Reuters reported that market participants believe the company could eventually emerge as a major AI infrastructure provider while expanding its Starlink satellite internet network. Analysts also see significant long-term potential if SpaceX successfully develops Starship and integrates AI capabilities across its operations.With a market capitalization of around $2 trillion, SpaceX has become the sixth-largest listed U.S. company, while Elon Musk has become the world's first trillionaire.The company was also added to FTSE Russell's U.S. indexes last month, allowing investors in funds such as the iShares Russell 1000 ETF to gain exposure to the stock.However, S&P Global has not introduced a similar fast-track mechanism for the S&P 500, which implies that SpaceX is unlikely to join the benchmark for at least another year.Since its June 12 debut, SpaceX shares have risen about 1%, although trading has remained volatile in the weeks following its record-breaking IPO.
