NEW YORK — The biggest question hanging over Elon Musk's empire right now is not about rockets or robotaxis — it is whether his two most valuable companies will eventually become one. A growing chorus of Tesla investors is betting that Musk will ultimately engineer a merger between Tesla — NASDAQ: TSLA — and newly public SpaceX, and the speculation is increasingly shaping how both stocks trade.
The chatter intensified this week as analysts and large holders openly framed a Tesla–SpaceX combination as Musk's likely "endgame." The dynamic has already shown up in trading, as we noted when Jefferies flagged the "proxy" risk as $TSLA and $SPCX began to diverge.
Why the Logic Is Compelling
The case for a tie-up is rooted in how intertwined the businesses already are. SpaceX's Starlink provides connectivity that complements Tesla's fleet; both lean on the same advances in power electronics and AI compute; and xAI, now folded into SpaceX, supplies the models behind Tesla's in-car assistant. A merger would unite that shared work in AI, batteries, manufacturing, and custom silicon under one roof — giving investors a single, cleaner way to own the entire Musk technology stack.
With SpaceX commanding a valuation in the trillions after its record IPO and Tesla's own cash position strong, Musk would have ample currency to pursue a deal on his own timeline.
Where the Tape Stands
For now, both stocks remain volatile. $TSLA recently changed hands around $375, holding a market capitalization near $1.4 trillion within a 52-week range of $288.77 to $498.83. $SPCX, which debuted at $135 on June 12 and spiked as high as $225 before pulling back, was trading near $153 — well off its highs but still valuing the rocket maker among the world's largest companies. Live quotes are available on Yahoo Finance, Google Finance, WSJ, and Nasdaq, with SpaceX's tape on Yahoo Finance and Nasdaq.
A Bet on Musk Himself
The volatility cuts both ways. SpaceX's swings since its debut have rippled into Tesla, and vice versa — a dynamic some traders have dubbed the "cult of Elon", where retail enthusiasm amplifies moves in both directions. But for long-term believers, that linkage is precisely the point: own one, and you are increasingly making a bet on the whole.
As we noted when $TSLA pulled back toward $375 this week, the recent softness has come on light volume, with conviction holders largely staying put. Whether or not Musk ever formally merges the two companies, the market is already treating them as halves of a single story — and the investors positioning for that endgame believe the most valuable chapter is still ahead.
