Rep. Gilbert Cisneros has filed a Periodic Transaction Report disclosing the sale of Comcast Corporation Class A Common Stock (CMCSA), according to records submitted to the U.S. House of Representatives under the STOCK Act. The transaction, dated July 17, 2026, was valued in the disclosed range of $1,001 to $15,000 and was made by the member of Congress personally.
The holding was reported through 150 Main Street Trust, held at Bank of America, a structure that indicates the shares were managed through a family or personal trust arrangement rather than a direct brokerage account. STOCK Act filings require members of Congress to disclose transactions like this within 45 days, regardless of the vehicle used to hold the asset, so the appearance of a trust intermediary here is a disclosure detail rather than anything unusual on its own.
This sale registers on our tracking system as a straightforward congress sale signal, meaning it reflects a reported disposal of shares by a sitting House member. The filing does not include any additional notes, explanations, or context beyond the transaction details themselves.
An Overlapping Insider Sale
What makes this filing notable is its timing relative to activity inside Comcast itself. Company insider Brian L. Roberts also sold CMCSA shares, in a transaction dated August 5, 2026, listed with a reported value of $0 in available records. That sale falls within roughly three weeks of Cisneros’s reported transaction date, placing both moves inside the same general window of Comcast-related trading activity being tracked across our platform.
We flag this kind of overlap because it is the kind of pattern our readers ask about most: a member of Congress and a company insider disclosing sales of the same stock within a short span of each other. It does not establish coordination, shared information, or any wrongdoing by either party, and STOCK Act disclosure itself is simply a legal transparency requirement rather than evidence of anything improper. Congressional trades and insider trades are reported through entirely separate systems, and timing overlaps like this one happen periodically across the thousands of disclosures filed each year.
Comcast has seen other congressional disclosure activity in recent months as well. Our earlier coverage detailed a similar situation involving another House member, in Kevin Hern Discloses CMCSA Sale Amid Insider Activity, which readers may find useful for additional context on how CMCSA has been showing up across multiple disclosure filings this year.
As with all STOCK Act filings, this report reflects a legally mandated disclosure and is provided here for informational tracking purposes only. We will continue to monitor CMCSA-related filings from both congressional and corporate insiders as new disclosures become available.
