Senate takes up a congressional stock-buying ban; in House filings this year, 3 members made 63% of the purchases

The Senate was set to hold procedural votes on Wednesday on a bill that would stop sitting members of Congress from buying individual stocks, CNBC reported. The Stop Insider Trading Act passed the House 232-198 in July. CNBC said it was unlikely to reach the Senate's 60-vote threshold, with Democrats opposed to a voter identification provision Republicans attached and to the fact that it would not require members to divest stocks they already own. Wednesday could be the Senate's last day in session before a recess of more than a month ahead of the midterm elections.

What the bill would actually have stopped

The bill targets purchases, not holdings, so the useful question is how much buying there is. We track House members' periodic transaction reports as they are filed with the House Clerk. Our tracker has parsed 403 such filings made in 2026, covering 2,500 transactions from 81 members, with trade dates from January 13 to September 22.

Limited to individual stocks, the filings show:

A handful of members do most of the buying

The purchases are concentrated. Three members account for 603 of the 963 purchases, or 63%: Gilbert Cisneros with 394 (41% on his own), April McClain Delaney with 129 and David J. Taylor with 80. That is the part the headline debate tends to miss. Of the 81 members in our data, 48 did not report buying a single individual stock this year, while a few trade often, mostly in small amounts.

The most frequently purchased ticker was Microsoft, with 22 purchases by eight different members. The largest single disclosed purchase in the dataset was a July purchase of Bloom Energy in a spouse account on Nancy Pelosi's filing, reported in the $1,000,001 to $5,000,000 range. Disclosures give only ranges, so the total value of all 963 purchases can only be bracketed: somewhere between about $7.0 million and $30.3 million.

What stays the same either way

CNBC's summary does not say how the bill treats accounts held by a spouse or child, which cover more than a quarter of the purchases above. Nor does a buying ban change the disclosure lag. Members can report a trade up to 45 days after it happens, so any filing is a look back, not a live signal of what they are doing now. That holds whether this bill passes or not.

For traders who follow these filings, the practical takeaway is narrow. A ban on new purchases would remove most of the buy-side filings but leave the sell side intact, since members could still trim or exit existing positions and would still have to disclose it. Every disclosed House trade, searchable by member and ticker, is on our congressional trades page.
