AI Semiconductors and Wall Street's Major IB Involvement: Controversy Over 'Supervisor's' Simultaneous Investment Unavoidable

U.S. Representative Josh Gottheimer (D-NJ) reported in a May 19 congressional disclosure that he purchased between $1,001 and $15,000 of shares in Advanced Micro Devices (AMD) on April 23 and 27, and in Goldman Sachs Group (GS) on April 16. He also made smaller acquisitions of CBIZ, First Watch Restaurant Group, Freeport-McMoRan and Infineon Technologies, but the most notable aspects of this filing are his simultaneous investments in a core AI infrastructure company and a major global investment bank.

AMD’s first-quarter 2026 results (Jan.–Mar.) beat Wall Street estimates, fueled by surging demand for data-center CPUs, GPUs and AI accelerators. Citing strong AI-chip demand, the company raised its second-quarter revenue outlook, sending its stock up about 20% immediately after the May 5 earnings release and more than doubling its year-to-date gains. With data-center revenue up over 50% year-over-year, AMD shares have climbed an additional mid-20% range since earnings, trading near all-time highs.

By contrast, Goldman Sachs beat first-quarter EPS and revenue expectations on April 13, but its fixed-income, currencies and commodities (FICC) unit fell well below consensus, prompting a roughly 3% drop in GS shares at the open. Over the following month, the stock moved sideways amid mixed sector trends: strong investment-banking and asset-management results offset by regulatory and capital-cost pressures.

Gottheimer serves on both the House Financial Services Committee and the House Intelligence Committee, where he is the Democratic ranking member of the NSA/Cybersecurity Subcommittee and sits on the Digital Assets, FinTech and AI Subcommittee. He has spearheaded AI-security legislation and bills to accelerate AI innovation in financial services, publicly called for stronger “smart AI” regulations at the White House, and recently urged tougher security protocols in response to a source-code leak at AI firm Anthropic. A member with direct legislative and oversight power holding positions in AMD and Goldman Sachs creates potential conflicts of interest, since forthcoming AI and financial regulations could materially affect these companies’ valuations and share prices.

Additionally, through the Financial Services Committee, Gottheimer influences rules for large banks, capital-markets and fintech, and helps design regulatory sandboxes and supervisory frameworks for digital assets and AI—potentially granting him access to nonpublic information on revenue dynamics or capital-requirement relief for institutions like Goldman Sachs. As Congress debates a bipartisan ban on individual stock trading by members, his AMD and GS purchases highlight the credibility and public-trust risks inherent in occupying both policymaking and market-participant roles.
