Tesla's aerial flips and wall-driving have little use for ordinary customers, making earnings from the demonstration hard to see and pointing to a lower share price. If the widely expected SpaceX merger is all-stock, a 10% lower Tesla price at signing would give Musk about 0.5 percentage points more of the combined company, at other Tesla shareholders' expense; he owns roughly 40% of SpaceX but 20% of Tesla. x.com  x.com 

Demand for a single way to invest in Musk's vision supports the case for a Tesla-SpaceX merger. Most investors spoken with want that option; the merger looks much closer than most expect, and Kalshi puts its chance before 2028 at 77%. If forced to own one of the two with a merger in prospect, SpaceX is preferable to Tesla because of Musk's ownership structure. x.com  x.com 

SpaceX's near-term earnings growth and potentially underappreciated compute ramp favor it over Tesla if their merger takes longer. SpaceX could exceed $200 by Q4 earnings; if the deal is announced within roughly a month, Tesla is the better trade because SpaceX would have to pay a premium of $420-$500+ a share. Tesla's robotaxi and humanoid earnings impact is still many quarters away, though both companies have longer-term upside. x.com  x.com 

Tesla's standalone upside is less clear at today's prices because a potential SpaceX exchange hinges on the premium Tesla holders receive and their share of the combined value. If SpaceX keeps executing at this pace, its upside, or that of the combination, looks clearer than Tesla's standalone upside. Execution remains a risk, and the valuation already discounts considerable optimism. x.com 

A Tesla-SpaceX merger could dilute Tesla shareholders while giving Musk greater voting control. The possible 15% dilution remains unconfirmed; Tesla shareholders could take on the risk as control consolidates, so a merger is not automatically a win for them. x.com 

SpaceX's orbital compute is a much bigger opportunity than Tesla's robotaxi, shifting merger gains toward Tesla holders over longer horizons. Robotaxi exceeds Starlink; Optimus needs more time and vast superintelligence. At today's share-price ratio versus no merger, Tesla holders are ~1.6x better off in 2031 and ~5x in 2036, versus ~2x and ~1.3x for SpaceX holders in the model. A roughly 30% Tesla premium balances 2031 gains; a roughly 50% Tesla discount balances 2036 gains. x.com  x.com 

SpaceX's shrinking cash balance points to another capital raise in Q4 2026 at this rate. Cash and equivalents fell from about $100B to $51.3B quarter on quarter, 43.76% below Wall Street's $91.2B estimate. That weakens the case for SpaceX buying Tesla, an auto maker trading at 235x 2026 earnings. x.com  x.com  x.com  x.com 

Tesla's $1.5T Elon premium looks unjustified while Musk seems to favor SpaceX for the AI compute buildout. Tesla shareholders missed almost the entire AI boom; owning xAI and building that infrastructure might have doubled Tesla's stock. Q3 adjusted EPS was $0.48, down 4% year over year; if Tesla were a non-Musk company, four such quarters at 10x earnings would mean $19.20 a share versus $386. Long-term company prospects remain attractive, but the stock is still not worth buying back. x.com  … Show more

A SpaceX acquisition of Tesla now seems very likely, at over $500 per share within the next 12 months. Investors are also bullish on robots and robotaxis, so Tesla's fundamentals and valuation do not seem to matter now and have not for some time. x.com 

Tesla's 200x earnings multiple asks too much of weak current results and speculative future products. Third-quarter revenue fell 0.4% year over year and EBIT missed estimates by 25%, despite gross-margin and cash-flow beats. Robotaxis, humanoids and other future plans may have appeal, but impressive parts of the business do not make the stock worth its current price. x.com  x.com  x.com
