Tesla SpaceX IPO shock: TSLA -3.1% plunge and Musk risk

How is Tesla trading as SpaceX nears IPO?

Tesla, Inc. (TSLA) traded lower around midday Tuesday, down roughly 3.1% to $397.36 versus a previous close of $409.47, as the Tesla SpaceX IPO narrative weighed on sentiment. The stock has rebounded sharply in recent weeks, recently touching a nine‑month high after a 27% monthly rally driven by stronger‑than‑expected Q2 delivery trends and renewed enthusiasm for Robotaxi and Optimus catalysts. But today’s pullback shows how quickly Musk‑linked headline risk can swing the tape.

Options desks highlighted heavy short‑term positioning ahead of the anticipated SpaceX S‑1 filing later this week, with traders bracing for volatility around any confirmed IPO terms. Structured‑product activity is rising as well: Barclays has launched multiple AutoCallable Notes tied to TSLA, including a 20% per‑year note that is automatically redeemed if the stock trades at or above $443.30, but exposes investors to full downside if Tesla ends below a $310 barrier at maturity. Those products underline how central Tesla’s volatility remains for yield‑hungry investors despite today’s weakness.

Will Tesla SpaceX IPO drain the ‘Musk premium’?

The core worry for many portfolio managers is that a high‑profile SpaceX IPO will carve away some of the upside that has historically been embedded in Tesla’s valuation. Tesla currently trades at more than 200 times expected earnings, a multiple bulls justify with the argument that the company is less an automaker and more a vertically integrated AI, robotics and energy platform. That narrative hinges heavily on Elon Musk’s track record of turning ambitious technology bets into shareholder windfalls.

The Tesla SpaceX IPO debate centers on whether that optionality now resides more in SpaceX than in Tesla. SpaceX is expected to go public at about $1.75 trillion, raising up to $75 billion and instantly ranking among the largest companies on U.S. exchanges, just ahead of Tesla on some league tables. Valuation specialists on Wall Street argue that the ‘Musk uplift’ once attached almost entirely to Tesla is likely to be shared across two securities after the SpaceX listing, potentially compressing Tesla’s multiple as investors can finally buy Musk’s space, satellite and xAI assets directly.

Some institutions are already repositioning across the broader mega‑cap complex. Viking Global, for example, recently opened a nearly $1 billion stake in Apple while also adding to Tesla, a sign that large hedge funds still see room for Musk‑linked growth stories inside diversified Big Tech portfolios. At the ETF level, Tesla’s 18.97% weight in the Consumer Discretionary Select Sector SPDR (XLY) has been a major driver of that fund’s five‑year outperformance versus rival products, underscoring how any multiple compression could ripple across passive vehicles.

Could a Tesla SpaceX IPO path lead to a future merger?

Overlaying the IPO story is a louder drumbeat of speculation that Musk ultimately wants to weld his core ventures into a single AI‑first conglomerate. Veteran tech investor Gene Munster has put the odds of a Tesla–SpaceX merger above 50% within five to ten years, describing the potential combination as a “sovereign AI company” spanning autonomous vehicles, Optimus humanoid robots, Starlink connectivity and launch infrastructure. Wedbush’s Dan Ives has gone even further in recent commentary, suggesting an 80%–90% chance that Musk attempts some form of combination once both companies are “properly valued” in public markets.

There is already real financial plumbing between the entities. Tesla injected about $2 billion of equity into SpaceX and is partnering on what it calls the largest chip fabrication project in the U.S., to be built around the Gigafactory Texas campus. Tesla also booked more than $500 million in revenue from xAI and SpaceX in 2025, reflecting shared AI and data‑center infrastructure. Bulls argue that a Tesla SpaceX IPO could simply be a stepping stone to a future roll‑up once public market valuations converge and regulatory paths are clearer.

Skeptics counter that merging a public automaker with a defense‑adjacent rocket and satellite company would invite intensive antitrust and national security scrutiny in the U.S. and abroad. Polymarket prediction markets currently price only a mid‑teens probability that a concrete merger announcement appears before year‑end 2026, suggesting traders see the theme as a long‑duration option rather than a near‑term catalyst.

Where do analyst views and competition fit in?

On the research side, traditional auto analysts remain split. Some, like long‑time Tesla bull Dan Ives at Wedbush, continue to frame Tesla as a core AI play inside the NASDAQ ecosystem, arguing that the market still underestimates the earnings power of Robotaxis, Optimus and in‑house AI chips. Television personality Jim Cramer has emphasized Tesla’s battery technology edge and FSD subscription potential, calling it more of a technology company than a carmaker and preferring it to legacy rivals such as Ford.

Others are more cautious. Independent analysts highlight that investors are still paying a steep premium for unproven Robotaxi and robotics businesses while core EV sales growth slows and competition intensifies. Waymo, backed by Alphabet, is widely viewed as ahead of Tesla in fully driverless robotaxi deployments, while Chinese EV makers are preparing a push into the U.S. market that could pressure margins. Meanwhile, Musk’s legal defeat in his OpenAI lawsuit serves as a reminder that he cannot always control the broader AI narrative, even as xAI and SpaceX deepen their own AI ambitions.

For now, Tesla remains a central node in the so‑called ‘Muskonomy’ alongside SpaceX, xAI and social platform X. Tokenized equity markets already feature synthetic exposure to Tesla and NVIDIA, underscoring how closely traders tie the company to the broader AI and speculative tech complex.
