Tesla might end up playing second fiddle to another Elon Musk company on its own earnings call.

The electric-vehicle maker lets investors submit and vote on questions to be raised on Tesla's $(TSLA)$ quarterly earnings call. And with earnings due out Wednesday, this quarter's top question for CEO Elon Musk concerns SpaceX, another company he leads.

"You once said: Loyalty deserves loyalty. Will long-term Tesla shareholders still be prioritized if SpaceX does an IPO?" reads the top-ranked question asked by a retail investor on Say.com, a platform Tesla uses to solicit inquiries to be answered on its earnings calls.

The interest in that question comes from investors who collectively own about 1.4 million shares of Tesla and who are increasingly curious about how they'll stack up as SpaceX approaches a potential initial public offering this year. SpaceX is targeting a valuation of as much as $1.5 trillion, compared to its current value of $800 billion. If the company is successful in meeting that mark, it would become worth roughly as much as Tesla is today.

How SpaceX would go about prioritizing Tesla shareholders is unclear, although Musk has repeatedly said he would like to do so. One potential method could be a directed share program, which companies use to set aside shares for a specific group of people that have a relationship with them, according to experts.

Shareholders are also focused on Tesla's plans for artificial intelligence and robotics, which is core to Musk and the company's vision. Executives said last week that Tesla had begun using a handful of autonomous vehicles without safety monitors in its robotaxi ride-hailing service in Austin, Texas, a milestone for the company.

Investors on Say.com asked for Tesla to elaborate on the bottlenecks currently limiting the company's ability to boost its deployment of robotaxis. They also want to know about the economics of Tesla's initial robotaxi efforts, with service so far available only in Austin and the San Francisco Bay Area.

Tesla collects an immense amount of data, which is one advantage analysts think it has in the robotaxi race. They're also upbeat about the company's ability to scale. In April, Tesla plans to begin production of the Cybercab, a vehicle that lacks pedals and a steering wheel.

"I think self-driving cars [are] essentially a solved problem at this point," Musk said last week, predicting that Tesla's robotaxi service will be "very widespread" by the end of the year.

Shareholders are also seeking clarity on Tesla's plans for its Full Self-Driving software, and when the company thinks it could unveil a more sophisticated version that has been labeled "unsupervised." The current advanced driver-assistance system is called "supervised" FSD and requires drivers to pay attention to the road.

Next month, Tesla plans to scrap the option for customers to buy FSD through a one-time payment, which would leave interested consumers locked in to a subscription plan that currently costs $99 per month. But Musk has said that price will rise as the system improves, with a "massive value jump" after unsupervised FSD is made public.

"The setup is less about whether Tesla beats or misses auto numbers and more about whether the company can keep the autonomy timeline feeling real rather than perpetually deferred," Shay Boloor, chief market strategist at Futurum Equities, told MarketWatch in emailed comments.

Another major topic investors want more information about is Tesla's Optimus humanoid robot. Musk last week said Optimus could be available to buy by the end of 2027, and that it has been used for "simple work" in Tesla factories but could be promoted to handling other tasks later this year.

Tesla is expected to host a demonstration for the next generation of Optimus in the current quarter, before launching volume production toward the end of the year. However, it's unclear if the company has managed to work out issues around designing and scaling the robots.

"So with cars, you've got an existing supply chain," Musk said on a prior earnings call. "With a humanoid robot, there is no supply chain."

And while many investors have their eyes set on an autonomous future, there's still some focus on EV sales, which account for most of Tesla's revenue and declined in 2025. An institutional investor with at least 3 million shares asked about whether Tesla will launch new models to address different vehicle segments, as well as how the rise of robotaxis will impact the car industry.

Investors have long been interested in seeing Tesla sell more affordable vehicles, and they somewhat got their wish last October when the company introduced cheaper trims of the Model Y and Model 3. But those models still start at nearly $40,000 and $37,000, respectively.

For customers unable to afford that price, the company is looking to come out with the Cybercab, which Musk has said could be sold for $25,000. That would make the Cybercab one of just a handful of EVs sold in the U.S. for less than $35,000.

However, Musk's vision involves selling the vehicle without steering wheels and pedals, which could be tricky. Tesla board chair Robyn Denholm told Bloomberg News last year that the model would be sold with both components if necessary to appease regulators.

Tesla's last vehicle launch was in 2023 with the Cybertruck, which has underwhelmed relative to Musk's massive expectations. Just 20,237 units were sold in 2025, a 48% drop from 38,965 deliveries a year earlier, according to Cox Automotive data.
