Tesla Stock Slips Overnight: Retail Turns Cautious On SpaceX Merger Hype As Analyst Questions ‘Absurd’ $2 Trillion Valuation

SpaceX’s newly disclosed $28.5 trillion TAM estimate, including $26.5 trillion tied to AI, drew sharp criticism from analysts who called the IPO filing "absurd" and a "trainwreck," citing $18.67 billion in revenue versus nearly $4.9 billion in losses. Tesla shares slipped 2% overnight after gaining 2% Wednesday as investors weighed merger speculation, while space stocks including ASTS, RKLB and SIDU rallied on IPO excitement. Retail sentiment was bearish on TSLA and bullish on SpaceX, underscoring a highly speculative setup.

Analysis

The near-term winner is not SpaceX itself but the entire satellite/launch adjacency basket, because the market is re-rating optionality faster than fundamentals. ASTS and RKLB have cleaner “pick-and-shovel” exposure to an investable space buildout, while SIDU is the most reflexive and likely the least durable beneficiary if this turns into a valuation reset rather than a broad capex cycle. The second-order risk is that a later-stage SpaceX filing becomes a gravitational force on capital, compressing the perceived scarcity premium in smaller public space names once investors realize they are paying up for businesses with far less scale, moat, and launch cadence.

TSLA is the key setup: the stock is being treated as a proxy for a broader Musk platform trade, but the current debate is shifting from narrative optionality to governance and capital structure complexity. If merger speculation gains traction, the upside is not from operating synergies in the next 1-2 quarters; it is from retail and passive flows re-underwriting Tesla as an AI/robotics/space holding company. The risk is that any concrete regulatory, tax, or options-market friction around a combination would force a de-rating before the market can price in the dream.

The contrarian read is that the “absurd” TAM language may still be useful because it expands the investable horizon, but the market is likely overestimating how quickly that horizon monetizes. For SpaceX-adjacent names, this is a classic sentiment spike that can persist for weeks, not years, unless the IPO path is delayed or the filing is challenged by execution scrutiny. For NVDA, the article is marginally positive only in the sense that AI infrastructure remains the funding pool for every futuristic narrative; however, the direct read-through is weak and should not justify chasing the stock on this headline alone.

Key Decisions for Investors

• Long ASTS / short RKLB as a 1-3 month relative-value trade: ASTS has the clearest asymmetry if investors keep bidding satellite connectivity as the ‘software-like’ part of the space stack; stop if RKLB outperforms on a concrete launch/customer catalyst.
• Sell into strength in SIDU over the next 1-2 weeks: highest beta name will likely overshoot on narrative flows, but it is also the most vulnerable to a post-hype air pocket; use call overwriting or outright short with tight risk controls.
• Maintain a tactical short/underweight in TSLA for the next 2-6 weeks via put spreads rather than outright shorts: the stock can squeeze on merger speculation, but headline risk is binary and the fundamental support remains weak relative to the narrative premium.
• Avoid chasing NVDA on this tape; if anything, use any AI-infra sympathy rally to trim into strength, since the article’s AI linkage is more about financing imagination than near-term demand acceleration.
• If TSLA/SpaceX merger chatter intensifies, consider a pairs trade long ASTS or RKLB vs short TSLA for a sector-beta-neutral expression of ‘space optionality’ without paying the governance complexity premium.
