House Speaker Nancy Pelosi’s husband purchased up to US$5 million (A$7.34 million) in stock options on semiconductor company Nvidia ahead of this week’s vote on the CHIPS act that would see billions of dollars in subsidies poured into the chip-manufacturing industry.

Paul Pelosi purchased 20,000 shares of Nvidia on June 17, worth between US$1-5 million. He also dumped shares and options in Visa and Apple during the same transaction.

If the bipartisan bill passes this week, it will see Nvidia share in US$52 billion in funding and tax credits in an order to bolster American semiconductor manufacturing.

“It certainly raises the specter that Paul Pelosi could have access to some insider legislative information,” Craig Holman, a government affairs lobbyist for Public Citizen, told the Daily Caller News Foundation.

“This is the reason why there is a stock trading app that exclusively monitors Paul’s trading activity and then its followers do likewise.”
