Here's something you don't see every day: a member of Congress buying into a private AI startup that reads like a who's who of Silicon Valley and celebrity investing. While retail investors often try to mirror congressional stock trades, one lawmaker is making that game much harder by going private.

Congresswoman Kelly Morrison (D-Minn.) recently disclosed she bought a stake in Arcade AI, a San Francisco-based generative AI marketplace. The investment was between $15,000 and $50,000, made through an investment fund. This isn't just another tech bet—it's a peek into how some in Washington are placing their money outside the public markets.

Arcade AI calls itself the "first ever AI physical product marketplace." It started in the jewelry sector, letting users "create real things with AI," and has since expanded to home goods. Since its beta launch in September 2024, users have created over 650,000 jewelry designs. In March 2025, the company raised $25 million in a Series A round, bringing total funding to $42 million.

Here's where it gets interesting. The Series A round included existing investors like Reid Hoffman, Offline Ventures, Inspired Capital, Torch Capital, and Ashton Kutcher via Sound Ventures. The company's angel investors include former NFL player Colin Kaepernick and supermodel-entrepreneur Karlie Kloss. So when Morrison bought in, she was joining a pretty exclusive club.

This isn't Morrison's first private company investment this year. Recent disclosures show stakes in high-speed aircraft manufacturer Hermeus Corp, robotics company Rhoda AI, and space company Varda Space. That's quite a shift for a congresswoman who had over $2.69 million in transactions in 2025, mostly in stocks, according to data from Quiver Quantitative.

She's not alone in this private company game. Rep. Lisa McClain (R-Mich.) recently disclosed buying a $100,000 to $250,000 stake in Elon Musk's xAI and a $50,000 to $100,000 investment in humanoid robotics company Apptronik. And former Speaker Nancy Pelosi (D-Calif.) has disclosed investments in private companies like Databricks in the past.

Here's the thing about congressional investments in private companies: they're perfectly legal as long as lawmakers follow the STOCK Act rules, including reporting transactions within 45 days. But they create a different kind of transparency problem. When a congressperson buys Apple stock, you can buy Apple stock. When they buy into a private AI startup, you generally can't—unless you're an accredited investor with the right connections.

Private company investing carries more risk than public markets—these are early-stage companies that might fail, get acquired for pennies, or never go public. But the potential upside is there too: early investors in companies that eventually IPO or get bought out can see spectacular returns. Morrison's portfolio suggests she's betting on several companies that could be tomorrow's big winners.

So what does this mean for investors watching Washington? The traditional "follow the leader" strategy gets complicated when the leader is playing a different game entirely. While Morrison's move into private companies might signal confidence in specific sectors (AI, aerospace, robotics), it's not a signal retail investors can easily act on. It's more like watching someone play high-stakes poker from outside the casino—you can see their bets, but you can't join the table.
