This is the biggest trader in Congress with over 1000 trades this last year

While Representative Nancy Pelosi has historically been the most scrutinized trader in Congress, Congressman Gil Cisneros – or his investment manager – has been working hard to take the lead since 2019.

Specifically, the Democrat from California has disclosed more than 2,300 equity buys and sales across his two terms in office: one between 2019 and 2021, and the other started in 2025 and ongoing.

Additionally, along with the impressive number of trades, Cisneros’ volume is nothing to scoff at, considering it is estimated at over $48 million across multiple sectors, including healthcare, industrials, information technology (IT), finance, and consumer discretionary.

Elsewhere, Representative Gil Cisneros has been drawing attention since 2026 by making numerous – and frequently well-timed – bets on the U.S. military-industrial complex, and by benefitting from his investments during the hot phase of the Iran war, and following the January attack on Caracas, Venezuela.

Still, the politician – or his manager – appears, judging by his trading history, to be a good judge of powerful trends. Indeed, some of the biggest companies he has invested in come from big tech and are often firms heavily involved with the artificial intelligence (AI) boom.

For example, even if one limits themself to only the buys and sales executed since March 1, Cisnteros has been actively adjusting his positions in blue-chip technology giants.

Nvidia (NASDAQ: NVDA), Microsoft (NASDAQ: MSFT), Tesla (NASDAQ: TSLA), SanDisk (NASDAQ: SNDK) – a memory stock that is up 3,200% in the last 12 months – Palantir (NASDAQ: PLTR), Amazon (NASDAQ: AMZN), and many others are all among the names disclosed within the last 30 days.

Is this Representative Cisneros’ top Congressional Trade?

Furthermore, Representative Gil Cisneros has also been successful in picking the winners among less prominent companies.

For example, the Congressman first invested in Bloom Energy (NYSE: BE) – a company that produces solid oxide fuel cells (SOFCs) for use in data centers and elsewhere – on September 26 and then enjoyed nearly a 31% rally before trimming part of the position on December 24, 2025.

He once again purchased BE shares on January 30, and the energy stock has rallied 90.24% since, while the total return since the original investment stands at a remarkable 309.51% as of press time on April 30, 2026.

Lastly, while the politician’s disclosures show his willingness to cross the Pacific to trade – on March 27, he sold Alibaba (NYSE: BABA) Hong Kong shares – his recent trading activity could also spark some concern since multiple sales of prominent AI stocks have been reported within the last month.
