Here's an interesting twist in the ongoing saga of congressional trading. Rep. Lisa McClain (R-Mich.) just disclosed a substantial investment in Apptronik, a privately held humanoid robotics company that's trying to beat Elon Musk at his own robot game. The irony? She already owns a hefty stake in Musk's xAI.
According to recent disclosures shared by Quiver Quantitative, McClain's spouse invested between $50,000 and $100,000 in Apptronik on January 12. This adds another private company bet to a trading portfolio that's raised more than a few eyebrows over the past couple of years.
The xAI Controversy Still Fresh
McClain made headlines earlier this year when it came out that her spouse had invested $100,000 to $250,000 in xAI, the parent company behind Musk's AI ambitions and the social media platform X. The company recently merged with SpaceX, potentially adding even more value to that investment.
The timing on that one was remarkable. The xAI investment happened just days before the Pentagon agreed to deploy the Grok chatbot for military use. When NewsNation asked McClain about potential insider trading, she laughed it off.
"Because if it was, we wouldn't have bought 100,000 shares, we would've bought a heck of a lot more," McClain said. She later clarified: "I can 100% assure you that we didn't have the insider information."
The "100,000 shares" comment was likely a slip referring to the $100,000 investment amount. Actual shares of that quantity in the privately traded company would probably be worth significantly more than her disclosed investment range.
Why Apptronik Matters
Apptronik isn't just another robotics startup burning through venture capital. The company just announced a $520 million Series A-X funding round, extending an already oversubscribed $415 million round from earlier in 2025. That brings total Series A commitments to over $935 million. These are serious numbers for a company most people haven't heard of yet.
The investor list reads like a who's who of corporate America. Repeat backers include B Capital, Google (GOOGL), Mercedes-Benz, and PEAK6. New investors joining this round include AT&T Ventures (T), John Deere (DE), and the Qatar Investment Authority.
The company plans to use the capital to ramp up production of Apollo, its humanoid robot, and expand deployments globally. Apptronik says the funding will help accelerate its time to market as it faces stiff competition from Chinese humanoid companies and, notably, Tesla Inc. (TSLA).
Tesla Versus Apptronik: The Robot Race
This is where McClain's dual investments get interesting. She owns stakes in both xAI and Apptronik, but Apptronik's Apollo robot is a direct competitor to Tesla's Optimus humanoid robot. Both companies are targeting a 2026 debut, with Musk aiming for deliveries to other companies that year and full-scale production by 2027.
Apptronik has lined up partnerships with Mercedes-Benz, GXO Logistics (GXO), Jabil (JBL), and Google DeepMind. Apollo is designed for logistics and manufacturing initially, with plans to expand into retail, healthcare, and eventually homes.
"Today's investment is a strong vote of confidence in our mission to deliver humanoid robots that are designed to work alongside humans, not just as tools but as trusted collaborators," said Jeff Cardenas, Apptronik's co-founder and CEO.
Ark Invest was also a previous investor in the 2025 Series A round. The Ark Venture Fund currently lists Apptronik as its 19th largest position at 1.87% of fund assets.
McClain's Trading Track Record
Members of Congress are allowed to invest in private companies as long as they disclose these investments the same way they report stocks, options, and cryptocurrencies. McClain's trading activity has certainly kept people watching.
A report from Quiver Quantitative ranked McClain as the third top gainer among congressional members for portfolio performance in 2025. Her investments returned 37%, more than double the S&P 500's 16.6% gain over the same period.
Her trading history has raised red flags before. McClain filed hundreds of stock transactions late last August, including purchases of Palantir Technologies, a stock that subsequently rose substantially. The company's extensive government contracts have put extra scrutiny on Congress members who own it.
In 2025 alone, McClain made hundreds of stock purchases, including multiple buys of Tesla stock.
According to data from Quiver Quantitative, McClain's wealth has grown by millions of dollars in recent years. With her investment in xAI, that wealth could increase further based on the success of Musk's ventures. The Apptronik investment is harder to read. Is she betting against Musk's humanoid robot vision, or is this a broader play on the humanoid robotics sector regardless of who wins?
Either way, McClain is positioning herself on multiple sides of the AI and robotics revolution. Whether that's savvy diversification or something else entirely depends on who you ask.
