Congressional trading is always a spectator sport for retail investors, but it gets extra interesting when the trades are in private companies. You can't just copy them, but you can still learn something about what the people with insider access think is worth a bet.
Sen. Tim Sheehy (R-Mont.) recently disclosed transactions in five private companies, as reported by the MarketDash Government Trades page. All the trades were disclosed on Aug. 13, 2026, and they cover a range of industries and geographies.
Here's the rundown:
- Nov. 4, 2025: Sold $50,000 to $100,000 in Sana Labs, a private Swedish software company.
- Nov. 3, 2025: Bought $1,000 to $15,000 in Grant Street Group, a Pennsylvania software company.
- July 8, 2025: Bought $1,000 to $15,000 in AIA Contract Documents, a Washington, D.C., construction contract software company.
- June 28, 2025: Sold $500,000 to $1,000,000 in Ansett Holdings, an aviation training company in Australia.
- June 16, 2025: Bought $1,000 to $15,000 in Constitution Surgery Alliance, a Connecticut health care company.
Members of Congress can buy stakes in private companies, but they still have to disclose those trades under the STOCK Act, just like they would for public stocks. That means a 45-day deadline for reporting. Sheehy's disclosure came well after that window, so he could face potential violations and fines. MarketDash reached out for comment and didn't hear back.
Sheehy isn't the only lawmaker making private bets. Nancy Pelosi's investment in Databricks and Lisa McClain's in xAI are recent examples of high-profile private company investments by members of Congress. It's a trend that's getting more attention as lawmakers look beyond public markets.
