For years, Tesla Inc. (NASDAQ:TSLA) investors have argued about one question that has never had a clear answer: How much of Tesla’s valuation belongs to Elon Musk?

The debate has become increasingly important as Tesla’s market value has grown far beyond what traditional automotive metrics would suggest. Bulls argue the company deserves a premium because it sits at the center of multiple disruptive technologies, from autonomous driving and robotics to artificial intelligence and energy storage.

Bears have long countered that part of Tesla’s valuation reflects something less tangible: the market’s willingness to bet on Musk himself.

Now, investors may finally get a way to measure it.

The Arrival Of A Second Musk Stock

The expected SpaceX IPO is generating excitement because it would give public investors access to one of the world’s most valuable private companies.

But the bigger implication may be what it reveals about Tesla.

For more than a decade, Tesla has effectively been the default way for many investors to gain exposure to Musk’s vision of the future. While SpaceX remained private, investors who wanted to bet on Musk’s ability to build industry-defining businesses had limited options.

That dynamic changes once SpaceX begins trading publicly.

Suddenly, investors will have two separate data points for valuing Musk-led innovation.

Measuring The Musk Premium

The timing is particularly interesting because Wedbush analyst Dan Ives recently said he sees an “80%+” chance that Tesla and SpaceX ultimately merge by 2027.

Whether that prediction proves correct may be less important than the valuation debate it has already sparked.

If SpaceX commands the kind of valuation some investors expect, potentially approaching $2 trillion over time, Wall Street will gain a powerful benchmark for assessing how much value investors assign to Musk’s leadership, vision and execution.

In other words, the market may finally be able to separate the value of Tesla’s businesses from the value of being associated with Musk.

A New Valuation Framework

The implications extend far beyond Tesla.

A publicly traded SpaceX would force investors to compare two very different Musk-led companies. One is built around electric vehicles, energy storage, robotics and autonomous driving. The other is built around launch services, satellite communications and space infrastructure.

Yet both are tied to the same founder.

That comparison could reshape how investors think about valuation across the entire Musk ecosystem.

For years, Tesla has been the only major public vehicle for investors looking to buy into Musk’s ambitions. Soon, they may have another option.

And for the first time, Wall Street may discover exactly how much the Musk premium is worth.
