Lawmakers invest in tech, AI, and crypto as new rules for the industries are on their agenda

As Congress debates new regulations around artificial intelligence and cryptocurrency, lawmakers' stock portfolios have surged in recent years toward investments in these sectors.

A tracker of the top 50 lawmaker holdings from the financial data platform Unusual Whales shows over $270 million invested directly in top tech stocks, with tens of millions more invested indirectly through market-tracking funds.

It is a level of consolidation that mirrors trends seen in the larger market, with tech far and away the favored sector among lawmakers: 7 of the 8 most popular individual stocks seen in the data are technology companies.

Nvidia ( NVDA ) is a bipartisan favorite, with about $43 million in lawmakers' accounts. Other tech giants, including Apple ( AAPL ), Alphabet ( GOOG ), and Microsoft ( MSFT ), also have tens of millions of dollars each in investment.

This represents a significant shift from recent years, when the proportion of tech holdings was much lower and was primarily seen in Democrats' portfolios.

Cryptocurrency holdings have also grown significantly in recent years, a trend particularly evident among Republicans. Increased investments in bitcoin ( BTC-USD ) and crypto-adjacent companies reflect heightened interest among Republicans in Trump-friendly areas of the technology sector writ large.

Dan Weiskopf is the co-portfolio manager of two ETFs that mirror Republican and Democratic portfolios. He notes that the Republican side of the aisle as a whole has become markedly more tech-focused and that Bitcoin has been a particular growth area — even requiring a rebalancing of his fund.

"It's clearly bigger," he said of Republican interest in Bitcoin. "There's no question about that."
