What is a bipartisan cluster?
One member buying a stock is a data point. A dozen members from both parties buying the same stock in the same few weeks is a pattern — and patterns are worth noticing.
What a cluster is
A cluster is when multiple members of Congress trade the same stock within a short window — typically several members buying the same ticker over a span of weeks. We flag a cluster as bipartisan when it spans both major parties. You can browse live clusters on the Consensus page.
Why it's more interesting than a single trade
Any one member's trade can be explained a dozen ways — a financial advisor's call, a spouse's account, a routine rebalance. But when a group of members, especially from opposing parties, converges on the same stock in a narrow window, the idiosyncratic explanations get weaker. A bipartisan cluster is harder to dismiss as one person's hunch, which is exactly why it rises in our Interest Score.
It is the difference between noise and a chorus. The cluster doesn't tell you why the convergence happened — that's for you to judge — but it reliably points you to the moments worth asking the question.
What a cluster is not
A cluster is not proof of coordination, insider information, or anything improper — and it is certainly not a recommendation to buy. Members may land on the same widely-covered stock for entirely independent, public reasons. What a cluster is is a transparency signal: a concentration of attention from the people who write and oversee the rules, surfaced so you can look closer. As always, read it to watch, not to copy.
Frequently asked
How many members make a cluster?
A cluster is several members trading the same stock within a short window; we highlight it as bipartisan when it spans both major parties. The Consensus page shows the current clusters and who is in them.
Does a bipartisan cluster mean the stock is a good buy?
No. A cluster is a transparency signal — a concentration of congressional attention worth examining — not an investment recommendation. Members may buy the same stock for independent, public reasons, and we make no claim that following a cluster beats the market.
