SpaceX shares fell again this week, extending a slide from their post-IPO highs and breaching a key support level, according to Barron’s. The decline has erased a substantial portion of the gains from the company’s debut, and it has put the spotlight on what investors see as the next test: entry into the Nasdaq-100 index.
The index addition is expected to accelerate, according to Investopedia, and it could bring billions of dollars in passive buying from funds that track the benchmark. For a stock that has struggled to find buyers at its current price, the forced demand from index funds is a rare piece of good news.
The company’s business is moving forward regardless of the share price. Starship 40, the latest version of its heavy-lift rocket, recently completed a single-engine static fire test, a step on the path to the test flights that have become the rhythm of the program. Each successful test reduces the technical risk that once dominated the story.
The market’s concern is narrower: profitability. SpaceX generates real revenue from Starlink, its satellite internet service, and from launch contracts, but the costs of the Starship program are enormous, and investors have begun asking when the spending produces commensurate returns. The question is not whether the company can fly, but whether it can earn.
The slide from the IPO high reflects that skepticism. Early buyers priced in a company that would dominate space the way the biggest platforms dominate their industries; later buyers are looking at quarterly numbers and asking for evidence. The gap between those two views is the distance the stock has already fallen.
Index inclusion will force a reconciliation. Passive funds do not ask questions about valuation; they buy according to rules. The influx of index-driven demand could stabilize the stock and give the company breathing room to deliver the growth its early investors expected.
The mechanics of the addition are worth watching. The Nasdaq-100 selects members by market capitalization and liquidity, and SpaceX’s size has made it an obvious candidate since its listing. The exact timing of the addition, and the size of the rebalancing flows, will determine how much support the stock gets and when.
Analysts said the passive flows could be substantial but not transformative. Billions of dollars would cushion the stock and reduce volatility, but they would not change the underlying story: a capital-intensive company with a long road to steady profits. Index membership is a floor, not a catalyst, they said.
The Starship program is the swing factor. The rocket is central to the company’s plans for satellite deployment and for the heavy payloads that future customers are expected to need. Success in the coming test flights would do more for the stock than any index addition, according to analysts.
The broader market context matters too. Space stocks have had a difficult stretch, with several recent listings trading below their offer prices, and the sector’s investors have grown wary of long-duration stories. SpaceX’s slide is partly a sector phenomenon — but its size makes it the sector’s most-watched test.
The company has options if the stock keeps falling. SpaceX has not signaled any plans to raise equity, and its cash position is strong by industry standards, but a sustained decline would complicate future fundraising and make employee stock compensation less attractive. Management’s incentives align with stabilizing the shares.
The support level that broke this week matters for the chart, if not for the business. Technical analysts had pointed to the level as the line between a normal pullback and a deeper correction, and its loss has triggered stop-loss selling that amplified the decline. The index addition, if it comes before the selling exhausts itself, could short-circuit the pattern.
Investors with longer horizons see the current price as an entry point. The company’s launch cadence, Starlink subscriber growth and government contracts give it a revenue base that most space companies lack, and the valuation, while rich, is below the levels set at the IPO. The disagreement between those buyers and the sellers of the past weeks is what makes the stock trade.
The company’s financial disclosures remain a source of friction. SpaceX publishes less detail than most public companies, and its quarterly reports have left analysts wanting more information about margins, backlog and the cost of the Starship program. Greater transparency, investors say, would narrow the gap between the bulls and the bears.
The next few weeks will resolve several of these questions at once. The index decision will come, the next Starship test flight is expected soon, and the company’s quarterly report will land shortly after. Each event will move the stock; together, they will define whether the slide was a correction or the start of something worse.
