Tesla's robotaxi expansion is driving recent optimism in its share price, but the rollout pace may slow until major software upgrades are in place.
Speculation about a SpaceX IPO and possible merger impacts Tesla's outlook.
Shares in Tesla (NASDAQ: TSLA) rose by 14.2% according to data from S&P Global Market Intelligence. The move comes down to a wave of optimism over the company's robotaxi expansion. There is reason to be optimistic for Tesla investors. Still, it needs to be grounded in reality, and investors also need to consider what the forthcoming SpaceX IPO might mean for Tesla investors.
The robotaxi expansion is the most important part of Tesla's foundational growth aspirations this year. That's why investors got excited when the unsupervised full self-driving (FSD) robotaxi fleet expanded from just nine in Austin at the start of April to 39 (28 in Austin, 5 in Dallas, and 6 in Houston) by the end of the first week of May.

However, according to robotaxitracker.com, the expansion suddenly stopped on May 10. And so did the share price. Indeed, the stock was actually up 16.6% in the month to May 11. The speculation around the robotaxi rollout is understandable, and there remains some confusion about its likely cadence. I want to clarify that now.
During the recentearnings call CEO Elon Musk fielded a question on whether the current v14.3 software was the last piece of the puzzle before "large-scale FSD" is available or "do we now have to wait until v15?"
Musk replied that v14.3 was indeed the last piece of the puzzle, then raised a point about "safety and convenience," and then stated that "I think it's not going to make sense for us to deploy unsupervised FSD or Robotaxi at large scale when we know that there are major architectural improvements to the software that can improve safety."
Tesla Director Askok Elluswamy then added, "We continue to expand based on the v14.3 base for a while until v15 lands. v15 is going to be a major upgrade." Clearly, investor expectations of a massive rollout ramp should be tempered here, as when Musk talked of "writing that software, validate it, and release it before going to large-scale unsupervised FSD," he's clearly not talking about v14.3.
Still, any rollout expansion is good news and helps create valuable data and raise confidence before v15 hits, hopefully later this year.
It would be remiss not to mention that Tesla stock is down 6.5% in June as I write, likely due to rising speculation that, following SpaceX's initial public offering (IPO), there might be a move toward a merger or acquisition of Tesla. While this is purely speculative and any merger/acquisition should be judged on the value of the deal, there's a strong case that such a deal would not be great news for Tesla investors.
After all, if Tesla is about to unlock value from robotaxis and Optimus in the coming years, it doesn't naturally follow that they should want to dilute their impact by becoming part of SpaceX, a company that will require substantial capital investment.
Speculation has been fueled by a recent amendment in its IPO filings stating, "We may issue a significant amount of equity in connection with future transactions." While it's simply legalese at face value, it does raise awareness of the potential for SpaceX to raise equity on the back of a favorable post-IPO valuation, and that's enough to cause concern for Tesla investors.

Four leading AI models discuss this article
"The robotaxi narrative is real but contingent on v15 delivery timelines that management has deliberately kept vague, while the SpaceX merger risk is speculative noise masking the actual question: does TSLA's current valuation price in a 2-3 year robotaxi ramp or assume it fails?"
The article conflates two separate narratives—robotaxi momentum and SpaceX IPO speculation—without quantifying either's impact on TSLA valuation. The robotaxi fleet expansion (9 to 39 units in 5 weeks) is presented as bullish, yet the May 10 halt suggests deployment constraints are real, not temporary. More critically: the article treats a SpaceX merger as a tail risk, but doesn't address the math. If Musk uses SpaceX equity to acquire TSLA, current TSLA shareholders face massive dilution unless SpaceX's post-IPO valuation is absurdly high. The 6.5% June decline is attributed to merger speculation, but no evidence is cited that this is the actual driver versus broader tech weakness or Q2 guidance concerns.
If v15 software lands in Q3 2024 and unlocks 500+ robotaxi deployments by year-end, the current 39-unit base becomes a rounding error—making today's caution look premature. And a SpaceX-TSLA merger could actually be accretive if SpaceX's IPO valuation is conservative and synergies in manufacturing/supply chain are real.
"Fleet expansion halt plus SpaceX equity-issuance language together cap near-term re-rating until v15 validation occurs."
The article correctly flags that Tesla's robotaxi fleet stalled at 39 vehicles after May 10, directly contradicting the narrative of an accelerating rollout. Musk's own comments on v15 as a required architectural leap imply that meaningful unsupervised scale is unlikely before late 2025 at earliest. The SpaceX IPO filing language on equity issuance for future deals adds real optionality for a transaction that would likely dilute Tesla shareholders' claim on autonomy cash flows without solving Tesla's capital intensity. Near-term price action will hinge on whether v14.3 miles driven can still produce regulatory credibility before dilution fears intensify.
Even a capped fleet at 39 vehicles could generate regulatory and insurance data faster than competitors if edge cases are logged efficiently, potentially front-running v15 and reducing the perceived need for a SpaceX tie-up.
"Tesla's current valuation relies on an aggressive timeline for autonomous software that remains technically unproven, leaving the stock vulnerable to significant multiple compression as capital expenditures rise."
The market's obsession with Tesla's robotaxi fleet size is a classic case of valuing a narrative over fundamentals. While the article highlights the pause in fleet expansion, it misses the deeper issue: Tesla is pivoting from a high-growth EV manufacturer to a speculative AI/robotics play. The valuation currently prices in near-perfect execution of FSD v15 and Optimus, yet Tesla’s core automotive margins remain under pressure from global competition. The SpaceX merger speculation is a distraction; the real risk is that Tesla’s capital expenditure on AI infrastructure will erode free cash flow long before robotaxis generate meaningful, scalable revenue. Investors are paying for a future that remains technically unproven.
If Tesla successfully achieves Level 4 autonomy via v15, the software-as-a-service margins will trigger a massive valuation re-rating that makes current price-to-earnings multiples look cheap in hindsight.
"Near-term upside for Tesla is contingent on an uncertain, capital-intensive robotaxi/FSD ramp and the potential for SpaceX financing to cause dilution, making the May rally more sentiment-driven than earnings-driven."
Tesla's May rally looks more like a sentiment lift tied to robotaxi hype and SpaceX IPO chatter than a proven earnings catalyst. The fleet rose to 39 robotaxi-ready Teslas by early May, but the cadence paused around May 10, and Musk signaled that v15--rather than v14.3--will be the meaningful upgrade. Even if v15 lands later this year, monetizing ride-hailing at scale requires regulatory clearance, favorable economics, and data-network effects that are far from assured. SpaceX financing or an IPO could stress Tesla's balance sheet through dilution or capital-allocation tradeoffs, potentially capping upside for now.
Bull-case: if v15 delivers real safety and cost improvements, robotaxi monetization could accelerate far faster than the article assumes. And SpaceX IPO dynamics could unlock strategic value or non-dilutive funding, not just capex pressure.
"Tesla's capex risk is regulatory timing, not technical execution or margin math."
Gemini flags margin erosion, but misses Tesla's actual leverage: robotaxi software scales at near-zero marginal cost once v15 ships. The capex burden is real, but if FSD achieves 99.9% safety by late 2025, SaaS revenue per vehicle could hit $10k+/year with 70%+ gross margins. That math inverts the 'unproven' narrative. The real risk isn't execution—it's regulatory delay. If California or NHTSA stalls v15 approval into 2026, capex becomes a sunk cost with no revenue offset.
"v15 technical delays could extend past regulatory ones, sustaining capex drag without revenue."
Claude's regulatory-delay focus underplays the technical timeline Musk himself flagged for v15 as an architectural leap. If that pushes unsupervised capability past mid-2026, the 70%+ SaaS margins never materialize while AI capex keeps rising. That directly amplifies Gemini's margin-erosion point rather than inverting it, leaving Tesla's valuation exposed to sustained automotive weakness without any offset from ride-hailing cash flows.
"Tesla's robotaxi narrative ignores the reality that Waymo is already scaling commercial operations while Tesla remains in the R&D phase."
Claude and Grok are debating the timing of software, but both ignore the actual competitive threat: Waymo. While Tesla debates the 'architectural leap' of v15, Waymo is already operating commercial, driverless fleets in multiple markets. Tesla’s data advantage is theoretical until they solve the 'unsupervised' hurdle. Even if v15 succeeds, they face a massive, capital-intensive uphill battle to capture market share from incumbents who have already solved the regulatory and operational logistics that Tesla is still just testing.
"Waymo's competitive threat is overstated for near-term profits; Tesla's real risk is capital intensity and regulatory delays, not a shrinking gap with Waymo by 2025."
Gemini's Waymo threat frame overclaims the near-term moat and underweights capital+regulatory risk. Even if Waymo operates driverless fleets, the marginal cost of scaling with data and insurance is enormous for all players; Tesla's real hurdle is ongoing capex and dilution from SpaceX financing, plus regulatory delays around v15 that stall revenue recognition. Waymo is a long runway risk, not an immediate stop — don't pretend the competitive gap shrinks by 2025.
The panel consensus is bearish on Tesla's current valuation, citing dilution risks from potential SpaceX financing, regulatory delays for Full Self-Driving (FSD) v15, and intense competition from Waymo in the robotaxi market.
