Executive summary
Senator Markwayne Mullin, a member of the Senate Appropriations Committee, purchased $15,001 - $50,000 of Citigroup (C) on January 5, 2026. This trade followed a series of financial sector purchases in late December 2025, including Goldman Sachs, amid ongoing regulatory discussions regarding bank capital requirements.
The purchase of Citigroup (C) appears to be part of a broader sectoral rotation into financial services by the member, as evidenced by simultaneous or near-simultaneous purchases in Goldman Sachs (GS), JPMorgan (JPM), and Capital One (COF) between late 2025 and early 2026. The timing of the trade (January 5) follows a mid-December Federal Reserve notice regarding capital rules and G-SIB surcharges, which are critical drivers for large-cap bank valuations. While the member does not sit on the Senate Banking Committee, his position on the Appropriations Committee—specifically the Financial Services and General Government subcommittee—provides oversight over the budgets of the SEC and other financial regulators. The ticker C has experienced a price decline of approximately 6.2% since the member's purchase price of $123.30, contrasting with his highly successful January 2025 trade in Stride Inc. (LRN).
