SpaceX overtakes Tesla as the top-valued company in Elon Musk’s portfolio, report says

Elon Musk’s corporate footprint is getting a new headline ranking. A Bloomberg report distributed by Yahoo Finance says SpaceX has surpassed Tesla to become the most valuable company in Musk’s portfolio, marking a shift in how investors and observers are valuing the billionaire’s two flagship operating engines.

The report indicates the relative valuation changed enough for SpaceX to pass Tesla, which has traded publicly for years and is widely tracked through its market capitalization and earnings expectations. Because SpaceX is not publicly traded, its value typically comes from financing rounds, reported buybacks, or secondary-market transactions, meaning the figures are less directly observable than Tesla’s.

Tesla remains the best-known public proxy for Musk’s strategy, with the company’s stock performance reflecting demand for electric vehicles, margins, regulatory credits, and progress across automation and energy products. SpaceX, by contrast, is valued largely through expectations about launch cadence, government and commercial satellite demand, and longer-horizon bets tied to reusability and next-generation rocket systems.

While the report’s key takeaway is the ranking change, the available information here does not include the exact valuation figures, the specific methodology used to estimate SpaceX’s value, or the date the comparison was calculated. It also does not spell out whether the change is driven by a reassessment of SpaceX’s growth prospects, a move in Tesla’s market expectations, or both.

The shift matters because Tesla and SpaceX are often discussed together as parts of a single technology and manufacturing ecosystem, but they operate under very different funding and disclosure regimes. Tesla’s value is continually updated in the public markets, whereas SpaceX’s valuation can lag or jump around based on discrete transactions that may not be frequent.

For Musk’s shareholders and the broader market, the implication is not only a new “most valuable” label but also a reminder that sentiment toward private assets can quickly reshape the perceived center of gravity of an entrepreneur’s wealth. A move like this can affect how analysts frame capital allocation, especially when investors weigh whether attention and investment will lean more toward near-term public-market deliverables or longer-dated private growth narratives.

It is also unclear from the available report information how much of Tesla’s position changed in valuation terms versus how much SpaceX increased. Without the numerical comparison and the underlying assumptions, investors are left to interpret the ranking change rather than model a precise bridge from one valuation level to another.

Next, market participants will likely watch for fresh data points that can sharpen the comparison, such as Tesla’s quarterly results and guidance, and any new SpaceX funding events, secondary transactions, or regulatory filings that can update estimates of SpaceX’s private-market value.
