Palantir Technologies (PLTR) posted the kind of earnings report that gets investors excited on Tuesday, with shares climbing as the data analytics company showed massive growth in its government business. But there's an interesting wrinkle: several members of Congress own shares in a company that's become increasingly controversial for its work with federal agencies, particularly U.S. Immigration and Customs Enforcement.

The stock surged 5.7% to $156.13, continuing a remarkable run that's seen shares climb over 86% in the past year. That's the kind of performance that makes Palantir a favorite among retail investors, even as questions swirl about potential conflicts of interest on Capitol Hill.

The Numbers Behind the Rally

Palantir's fourth-quarter revenue hit $1.41 billion, crushing the Street consensus estimate of $1.33 billion and representing a stunning 70% year-over-year increase. The company's U.S. segment brought in $1.08 billion, split between $507 million in commercial business and $570 million from government contracts.

That government revenue number is particularly noteworthy because it grew 66% year-over-year, even as the company faced internal pushback. A WIRED report highlighted that some Palantir employees have questioned the company's work with ICE, adding a layer of controversy to what would otherwise be a straightforward growth story.

Who in Congress Is Holding Palantir?

Owning shares in a company with significant government contracts, especially one working closely with ICE, creates some uncomfortable optics for elected officials. According to government trading disclosures, at least nine Congress members made Palantir transactions in 2024 and 2025.

Rep. Rob Bresnahan (R-Pa.) has been active, buying $1,000 to $15,000 worth of shares on April 8, 2025, after selling and rebuying similar amounts in late February.

Rep. Gilbert Cisneros (D-Calif.) has been steadily accumulating shares, with five separate purchases ranging from $1,000 to $15,000 each, spread from January 2025 through November 2025.

Rep. James Comer (R-Tenn.) made a single purchase of $1,000 to $15,000 on January 21, 2025.

Rep. Cleo Fields (D-La.) has been the most aggressive buyer, with six purchases in 2025 totaling potentially hundreds of thousands of dollars. His largest transaction was a $100,000 to $250,000 purchase on July 18, 2025, followed by multiple buys in the $50,000 to $100,000 range.

Rep. Jonathan Jackson (D-Ill.) bought $15,000 to $50,000 worth of shares on December 22, 2025.

Rep. Julie Johnson (D-Texas) has both bought and sold, with two sales and two purchases in 2025, each in the $1,000 to $15,000 range.

Rep. Lisa McClain (R-Mich.) has the longest trading history on this list, with eight disclosed transactions dating back to June 2024. Her most significant move was a $100,000 to $250,000 purchase on November 7, 2024, right after the election.

Rep. Jefferson Shreve (R-Ind.) sold $50,000 to $100,000 worth of shares on May 12, 2025.

Former Rep. Marjorie Taylor Greene (R-Ga.) also disclosed four Palantir purchases in 2025, each valued at $1,000 to $15,000.

The STOCK Act Problem

McClain's trading activity raises some red flags beyond just potential conflicts of interest. As chair of the House Republican Conference, she's one of the highest-ranking Republicans in Congress. But she reportedly disclosed several 2024 transactions late in 2025, potentially violating the STOCK Act, which requires timely disclosure of stock trades. She disclosed selling $50,000 to $100,000 in Palantir stock on October 23, 2024, and buying $100,000 to $250,000 on November 7, 2024, but these disclosures came months after the transactions occurred.

Where the Conflicts Get Interesting

Some of these Congress members serve on committees that directly oversee agencies and policies related to Palantir's business. That creates potential conflicts of interest worth noting:

• Cisneros serves on the House Armed Services Committee, which has jurisdiction over defense matters where Palantir has significant contracts.
• Jackson sits on the House Committee on Foreign Affairs, another area where Palantir's work intersects with congressional oversight.
• Johnson serves on both the House Committee on Homeland Security and the House Committee on Foreign Affairs, putting her in direct oversight of agencies that contract with Palantir, including ICE.

These committee assignments mean these representatives could potentially influence policy decisions affecting a company they own stock in, or could have access to non-public information about contracts and agency priorities.

Looking Ahead

Palantir shares have traded in a 52-week range of $66.12 to $207.52, and Tuesday's price of $156.13 represents a solid recovery from recent lows while still sitting well below the peak. The company's ability to grow government revenue despite controversy suggests its technology remains in high demand, even as questions about oversight and conflicts of interest continue to simmer in Washington.
