A newly released report on congressional trading activity in 2025 shows that several U.S. lawmakers once again outperformed the broader stock market, continuing a pattern observed consistently since 2020.
The data highlights a wide performance gap between top-performing political portfolios and the S&P 500, raising renewed questions about timing, access, and market awareness among elected officials.
According to the dataset, many members of Congress executed trades that significantly exceeded benchmark returns. While the S&P 500 posted a year-to-date gain of +16.8%, a notable group of lawmakers delivered substantially higher results, with some portfolios generating returns that were multiple times larger than the index.
Top Performers Show Exceptional Returns
The performance ranking reveals several standout figures. At the top of the list, Rep. Warren Davidson recorded an estimated +78.8% return in 2025, followed closely by Rep. Donald Norcross at +70.8% and Rep. Terri Sewell at +67.9%. A cluster of lawmakers posted gains between +60% and +50%, including Rep. Bryan Steil, Sen. Alex Padilla, and Rep. Nick LaLota.
Even further down the list, many portfolios still comfortably outpaced the broader market. Returns in the +30% to +40%range were common, nearly doubling the S&P 500’s performance. This concentration of above-market results reinforces the observation that congressional trading success in 2025 was not isolated to one or two individuals, but spread across a wide group of active traders.
Underperformers Highlight the Extreme Dispersion
While the upside was substantial for some, the chart also shows sharp underperformance at the bottom end. Rep. Chip Roy posted a steep -59.0% return, making him the worst performer in the dataset. Sen. Mitch McConnell also ended the year slightly negative at -1.8%, significantly trailing both peers and the market.
This wide dispersion, from nearly +80% gains to losses approaching -60%, underscores the high-risk, high-variance nature of individual stock selection within congressional portfolios. It also highlights that outperformance is not universal, even among lawmakers with frequent trading activity.
A Persistent Pattern Since 2020
The 2025 results align with a broader historical trend. Each year since 2020, a subset of politicians has managed to outperform major indices, often by large margins. The consistency of this pattern has kept congressional trading under scrutiny, particularly when unusually well-timed trades coincide with major policy discussions, sector-specific legislation, or macroeconomic shifts.
While the data alone does not establish causation, it continues to fuel debate around transparency, disclosure timing, and whether existing trading rules for lawmakers are sufficient. As 2026 begins, the latest figures add fresh momentum to calls for tighter oversight and clearer boundaries around stock trading by public officials.
In market terms, however, the takeaway is clear: in 2025, a select group of congressional traders didn’t just beat the market, they left it far behind.
