SpaceX says any merger with Tesla would require Elon Musk’s approval, while also disclosing it has been buying Tesla Megapack battery systems, underscoring how tightly the two companies’ finances and strategy are already intertwined.
Tesla Megapack Sales to SpaceX Disclosed

The disclosure matters because it reinforces that Musk remains the gatekeeper for any corporate combination involving his biggest assets, even as Tesla investors continue to debate how much of the CEO’s attention should be devoted to electrified cars, robotics and artificial intelligence. For investors, the bigger issue is less the prospect of a near-term merger than the signal that SpaceX is now a meaningful customer of Tesla’s energy-storage business, adding another revenue stream tied to Musk’s private company.

Tesla shares were last at $403.30, leaving the stock above both its 50-day and 200-day moving averages, while RSI readings near 59 suggest momentum remains constructive but not stretched. The stock has also been trading near the upper end of its recent Bollinger Band range, and Adalytica’s Tesla earnings sentiment gauge shows “Greed” at 82, indicating elevated optimism ahead of the next catalyst.
Megapack purchases matter because Tesla’s energy-storage unit has become one of the company’s most closely watched growth drivers, with deployments often swinging quarter to quarter depending on project timing and logistics. A relationship with SpaceX gives Tesla another large-scale internal buyer at a time when the company is trying to justify a premium valuation not just on car sales, but on the broader Musk ecosystem.
The disclosure also arrives as investors are already focused on Musk’s competing capital demands. Tesla is spending heavily on AI, semiconductors and autonomy, while SpaceX continues to expand its own capital-intensive launch and satellite businesses, making any structural link between the two a governance issue as much as a commercial one.
For now, the key takeaway is that the Musk empire is becoming more operationally connected, not less. That keeps Tesla’s energy business, SpaceX procurement and any future corporate maneuver firmly on investors’ radar, with more detail likely to be scrutinized in upcoming filings, product updates or any fresh comments from Musk.
