Tammy Baldwin: No Disclosed Stock Trades

Tammy Baldwin Congressional Trading Profile | Quantellect Tammy Baldwin Congressional Trading Profile | Quantellect

Tammy Baldwin, the Wisconsin Democrat serving in the United States Senate in a term that runs from January 3, 2025 through January 3, 2031, has no disclosed securities transactions in the record maintained by Quantellect. There is no purchase, sale, or other transaction on file under any attribution category, and consequently no basis for describing her trading habits, sector activity, or preferred securities. That absence is itself the profile.

Baldwin is not an outlier in this respect. Of the 537 members sitting in Congress as of August 22, 2026, 276 have no disclosed trades on record, including 39 of the 100 sitting senators. A large share of Congress simply does not generate a trading record under the disclosure regime established by the Stop Trading on Congressional Knowledge Act of 2012, and Baldwin's file falls into that group.

What the Disclosure Regime Requires, and What It Does Not Show Here

The STOCK Act requires members of Congress to report covered securities transactions no later than 30 days after receiving notification of them and in no case later than 45 days after the transaction. In the Senate, that filing runs through the process described in the Senate Select Committee on Ethics financial disclosure guidance. Transaction data can distinguish attribution categories including the member, a spouse, a dependent child, a joint account, or an unspecified attribution. That distinction matters because a transaction associated with a senator should not automatically be characterized as a personal trade.

None of that attribution machinery has anything to evaluate in Baldwin's case, because the underlying data set contains zero transactions associated with her under any category, whether personal, spousal, joint, dependent, or unspecified. There is no first transaction date and no most recent transaction date on file, no year-by-year pattern to trace, and no frequently disclosed security to point to. A profile built on trading data has nothing to build on here.

The transaction record also offers no sector breakdown, security-level pattern, or transaction-type mix beyond zeros. With no transaction rows, there are no disclosed companies, tickers, amount ranges, or instrument types to summarize. Any discussion of preferred sectors, securities, or trading themes would therefore go beyond the transaction evidence available here.

Score Availability

Separately from the transaction record, Quantellect publishes trading-activity scores for some members as of a given date. As of the latest published score date, August 21, 2026, 76 members had score rows, including 73 of the 537 sitting members. Baldwin was not among them. No score row exists for her as of that date, so there is no score, tier, cohort ranking, coverage state, or formula version to report.

What can be said with confidence is narrower than a typical congressional trading profile, but it is not nothing. Baldwin's file sits alongside those of 38 other sitting senators and 237 sitting House members with the same characteristic: no disclosed trade on record as of the measurement date of August 22, 2026. The record establishes only that no transactions appear; it does not identify the reason for their absence. The STOCK Act's periodic transaction reporting regime records covered activity that is disclosed, while a zero-transaction record does not by itself explain why no activity appears.

Should a disclosed transaction be added in the future, its transaction date and disclosure date should remain distinct, any amount should be presented as a disclosed range, and its attribution should match the filing. As of August 22, 2026, Baldwin's record remains what it is: a senator with no disclosed securities transactions on file.
