Quick Read – Slate Money co-host Felix Salmon theorized Trump’s 10x quarter-over-quarter trading surge may stem from anticipated changes in personal tax exposure on capital gains. – The analyst who called NVIDIA in 2010 just named his top 10 AI stocks.
The Slate Money hosts opened their latest episode with a number that should make every investor sit up. President Trump’s stock trading activity jumped roughly 10x quarter over quarter, rising from around 300 trades in one period to a volume that, by dollar amount, exceeded the combined trading of every member of the House and Senate. That is the entire legislative branch, on one side of the scale, and a single executive on the other.
The framing from co-host Emily Peck was direct: “The amount of money he traded in the quarter was more than all the trading by Congress all put together.” For context on what that benchmark actually looks like, congressional trading data shows most individual filings cluster in the $1,001 to $15,000 range, with occasional outliers. The largest recent disclosure in the House dataset was Jefferson Shreve’s $5,000,001 to $25,000,000 annuity exchange filed March 14, 2026, and even Nancy Pelosi’s January 16, 2026 AllianceBernstein partial sale of $1,000,001 to $5,000,000 sat well below what would be needed to rival a presidential book on its own. The Tax Theory Co-host Felix Salmon floated the most concrete hypothesis for the surge. “There is a non-zero chance that the thing that changed was that he knew that he wouldn’t have to pay income tax on the gains anymore,” Salmon said.
