SpaceX's AI business and profitable growth challenge calls for its stock to go much lower. Q3 revenue reached $14.6B, up 161%, with $4.4B profit and $7.6B from AI. A Tesla merger is being discussed. 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 

Tesla's AI upside depends on Elon Musk keeping AI inside the company. He could take it out and leave Tesla as a car company, so holders should not get too cocky; at current levels, $500 or $550 would still be hard to turn down. x.com 

SpaceX's AI spending is producing much more compute revenue without a comparable rise in capex, supporting its Overweight rating and $214 target. AI compute brought in about $7.6B versus $2.6B last quarter and ~$6.4B expected, while capex was $19.59B, in line with estimates. But cash of $51.29B versus $91.2B expected raises funding questions, and launches missed estimates. x.com  x.com  x.com  x.com 

Tesla's stagnant car business and rising AI and robotics spending are squeezing current earnings before those bets have paid off. Q3 revenue was flat as auto sales slipped and regulatory credits collapsed; operating expenses rose 39%, operating income fell 56%, and EPS dropped from $0.43 to $0.24. The spend-now, profit-later strategy is testing investors' patience. 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 bear-case risks compound faster than its bull catalysts because the stock is priced on optionality. DCF, comparable-company and precedent-transaction methods all put fair value materially below the current price, leaving it reliant on assumptions no standard method can verify. Raising 2026 capex from $20B to $25B+ for Terafab, AI5, Optimus and Robotaxi sacrifices near-term earnings, the HW3 issue is a real liability, and Robotaxi edge cases are resolving slower than bulls priced. x.com  … Show more

Tesla's valuation is too stretched to justify buying now. Slava cites a 189x forward P/E, falling Q3 deliveries, a 1.4% operating margin and negative free cash flow; other investments look preferable. 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 

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
