July 7: Mandatory Index Inclusion

This is the most certain of all the upcoming catalysts.

July 7 marks SpaceX’s 15th trading day after listing, when it will officially be added to the Nasdaq-100 Index.

This inclusion is possible because Nasdaq revised its index methodology in March this year, with the new rules officially taking effect on May 1. Under the revised rules, newly listed companies are evaluated by market capitalization on their seventh trading day. If they qualify, they can be added to the index as early as the 15th trading day, completely replacing the previous system that often required a wait of up to a year and only allowed adjustments once annually in December.

Nasdaq itself has acknowledged that the rule change was largely designed to pave the way for SpaceX.

What does index inclusion mean? Passive funds must buy the stock.

A large number of ETFs and index funds that track the Nasdaq-100 will be required to establish positions based on SpaceX’s free-float weighting once it is added to the index.

The Invesco QQQ Trust alone manages approximately US$477 billion in assets and is expected to become one of the largest sources of passive buying demand.

How large could the impact be?

Index-rebalancing research firm Intropic estimates that passive investors’ ownership of SpaceX’s free float could surge from current minimal levels to roughly 30%.

Market estimates suggest these passive inflows could total between US$8 billion and US$18 billion.

The other side of the equation is that there are almost no sellers.

Early investors and employees remain subject to IPO lock-up restrictions and are unable to sell their shares.

With free float constrained and passive buying mandatory, the resulting supply-demand imbalance could potentially drive an extreme upward move.

The buyers are passive, mandatory, and massive.

The sellers are locked up, restricted, and largely absent.

This type of structural supply-demand imbalance is almost unprecedented in the history of index inclusions.

Late July Earnings Report: The Seller Window Opens

SpaceX is expected to release its second-quarter 2026 earnings report in late July.

Two business days after the earnings call, the first lock-up expiration window will officially open.

At that point, early institutional investors and certain eligible employees will be permitted to sell up to 20% of their holdings.

Currently, only approximately 4.25% of SpaceX’s total shares are freely tradable, consisting entirely of newly issued IPO shares and greenshoe allocations.

Following the first lock-up expiration, the tradable float could expand several times over.

Early investors and employee shareholders generally have extremely low cost bases and substantial unrealized gains.

Once the lock-up expires, the true intensity of profit-taking demand will become a key variable to watch.

SpaceX’s financial fundamentals provide important context for this analysis.

The company reported a net loss of US$4.94 billion for full-year 2025 and a net loss of US$4.28 billion during the first quarter of 2026.

Since its founding, cumulative losses are estimated at approximately US$41.3 billion.

Revenue continues to grow, reaching US$18.67 billion in 2025, but growth has begun to slow.

First-quarter 2026 revenue growth was only 15%, significantly below the company’s projected full-year growth rate of 33%.

The company itself acknowledged in its prospectus that: “We may not achieve overall profitability in the future.”

With profitability still unproven, whether early institutional investors will continue holding or choose to realize substantial gains remains an open question.

July to August: Tesla and SpaceX Could Potentially Merge

The two companies already share several areas of business overlap, including collaboration on the Terafab chip project, shared AI data center infrastructure, energy storage projects, and the integration of xAI’s Grok model into Tesla’s vehicle systems. This is not mere speculation. In its IPO regulatory filings, SpaceX added a new risk-factor disclosure stating that it may issue substantial amounts of equity in the future for acquisition-related transactions. When language appears in official filings, it is usually already under active discussion.

However, the obstacles to a merger are equally real. Tesla shareholders would need to consider that, following a merger, SpaceX’s multi-billion-dollar annual losses and significant capital expenditures would be consolidated into Tesla’s financial statements, potentially slowing the pace of Tesla’s current earnings improvement.

At present, there is no clear timetable for such a transaction. Nevertheless, it provides another useful analytical framework. SpaceX’s IPO was not simply the completion of a standalone public offering; it also satisfied a more important prerequisite — SpaceX now has publicly traded stock. If any future form of restructuring requires publicly listed shares as acquisition currency, that condition has now been met.

Another important variable is Elon Musk’s personal situation. Market estimates suggest that Musk faces approximately US$7 billion in tax obligations, with related stock option exercise deadlines expected around August. The taxes involved include the maximum federal marginal tax rate of 37%, California state tax of 13.3%, and the 3.8% Net Investment Income Tax, resulting in a combined effective tax rate of approximately 54%.

Musk currently does not receive a cash salary and primarily relies on equity-based compensation and tax planning. As a result, he would likely need to generate cash through stock sales to meet these tax obligations. From an execution standpoint, many analysts believe Musk is highly likely to sell shares once lock-up restrictions begin to expire in order to raise funds for tax payments. If that occurs, it would represent a substantial source of selling pressure.

In addition, Microsoft co-founder Bill Gates previously indicated that he intends to sell his SpaceX holdings following the company’s public listing, a plan that has already been publicly reported. As a result, supply pressure after the lock-up expiration could emerge from multiple directions simultaneously.
