Congressional Stock Trading Ban: Every Bill, Every Vote, Every Stall
86% of Americans support banning congressional stock trading. 343 of 538 members still trade. Multiple bills have been introduced. None have passed. Track the legislation live.
The Current State of Play
As of April 2026, the congressional stock trading ban remains one of the most popular yet most stalled policy proposals in American politics. Multiple bills in the 119th Congress (2025-2026) would prohibit members from buying and selling individual stocks. Bipartisan support exists in both chambers. Floor votes keep getting delayed.
Meanwhile, the trading continues. According to STOCK Act disclosures tracked by GovGreed, 343 of 538 sitting members of Congress (63.8%) actively trade individual stocks. The platform has cataloged 189,595 individual trades since 2012 across 7,798 companies, worth billions of dollars in estimated volume.
The disconnect is stark: polling consistently shows 86% public support for a ban, cutting across party lines. Yet no ban bill has reached a floor vote in either chamber during the current Congress. Committee referrals, leadership scheduling, and procedural holds have blocked progress on every proposal introduced.
Active Ban Bills
At least five bills in the 119th Congress would ban or severely restrict congressional stock trading. They span both chambers and both parties. Here is their current status, based on GovGreed's tracking of 42,199 bills in the congressional database.
| Bill Name | Sponsor | Chamber | Status | Key Provisions |
|---|---|---|---|---|
| Stop Insider Trading Act S.1879, 119th Congress | D Sen. Jeff Merkley | Senate | In Committee | Full ban on individual stock trades; blind trust mandate; 90-day divestiture window |
| End Congressional Stock Trading Act H.R.1908, 119th Congress | R Rep. Chip Roy | House | In Committee | Bans stock transactions; allows index funds, mutual funds, Treasuries |
| Ban Conflicted Trading Act S.712, 119th Congress | D Sen. Elizabeth Warren | Senate | In Committee | Extends ban to spouses and dependents; covers senior staff; qualified blind trust required |
| ETHICS Act H.R.645, 119th Congress | BI Bipartisan coalition | House | Introduced | Comprehensive ethics reform; trading ban as Title II; strengthened disclosure penalties |
| Bipartisan Ban on Congressional Stock Ownership Act S.2041, 119th Congress | R Sen. Josh Hawley | Senate | Introduced | Ownership ban (not just trading); 6-month divestiture; applies to all family members |

History of Ban Attempts
The push to restrict congressional stock trading is not new. Every major attempt has either been watered down or stalled entirely. Here is the legislative timeline.
Arguments For a Trading Ban
The Case For a Ban
- Information asymmetry. Members receive classified briefings, sit on committees overseeing specific industries, and have advance knowledge of legislation that moves markets. GovGreed's data shows 256,112 bill-trade correlations where members traded stocks in sectors affected by bills they had advance knowledge of.
- Committee members outperform. Analysis of 189,595 trades shows that committee members trading in sectors they regulate generate statistically significant excess returns. GovGreed's Triple Signal analysis found bills where the controlling committee member simultaneously holds sector stock and received campaign contributions pass at 5.4x the rate of average legislation.
- Enforcement has failed. The STOCK Act's disclosure mandate has not worked. 23,426 filings (12.5%) were late. The average disclosure gap is 44.9 days, meaning many trades are not public until well after any informational advantage has been exploited. The worst gap was 997 days.
- Public trust. 86% of Americans support a ban. This is among the highest bipartisan support for any policy proposal. Congress trading stocks while voting on the laws that affect those stocks erodes institutional legitimacy.
- Predictable patterns. GovGreed's 7-layer signal model, scoring trades across politician quality, herd activity, bill timing, technical context, sector momentum, lobbying alignment, and campaign contributions, achieves a 72.7% win rate for A+ tier signals. If outside observers can predict the pattern, the information asymmetry is real.
The Case Against a Ban
- Property rights and personal finance. Members of Congress are citizens with the same rights to manage their finances. A ban could be seen as an unconstitutional restriction on personal property. Some constitutional scholars argue the 5th Amendment protects the right to buy and sell securities.
- Blind trusts as an alternative. Rather than an outright ban, requiring qualified blind trusts would eliminate the conflict of interest while allowing members to maintain their wealth. The argument is that a ban is a more extreme measure than necessary.
- Talent recruitment and retention. Restricting financial activity could discourage successful business leaders and investors from running for office. If Congress cannot attract people with financial expertise, the quality of economic legislation could suffer.
- Constitutional concerns. Article I, Section 6 of the Constitution provides certain privileges and immunities to members. Some legal scholars argue that restricting a member's financial activity could face challenges under the Speech or Debate Clause, though most legal analysis considers a trading ban constitutional.
- Scope and enforcement complexity. Defining what counts as a "stock" is difficult. Should the ban cover options, ETFs, crypto, SPACs, private placements? Every carve-out creates a loophole. The more comprehensive the ban, the harder it is to enforce.
What the Data Shows
GovGreed's analysis of 189,595 STOCK Act disclosures filed between 2012 and 2026 provides the most comprehensive public dataset on congressional trading. Here is what the data reveals about the case for a trading ban.
The STOCK Act requires disclosure within 45 days of a trade. In practice, the average disclosure gap is 44.9 days, and the median is 28 days. This means the public learns about congressional trades weeks or months after they happen, rendering the transparency mechanism nearly useless for real-time accountability.
The worst offenders file hundreds of days late. The single worst gap in GovGreed's dataset: 997 days between trade and disclosure. Among the most active traders, Michael McCaul (R-TX) has filed 6,670 late disclosures out of 32,302 total trades. Thomas Suozzi (D-NY) filed 86.4% of all trades late, with an average gap of 396 days.
GovGreed tracks 256,112 bill-trade correlations that link congressional trades to legislative activity. When a committee member buys stock in a sector directly affected by a bill they are reviewing, it is flagged. The Triple Signal occurs when three conditions align: committee position, sector stock holding, and campaign contributions from the same industry. Bills meeting all three conditions pass at 5.4x the average rate, validated on 37,143 held-out bills.
This does not prove illegal insider trading. It proves the structural conditions for conflict of interest exist at scale, and that the current disclosure system does not prevent or even adequately document them.

What Happens If a Ban Passes?
If a congressional stock trading ban becomes law, the implementation would involve several key transitions. Here is what each would look like based on the most comprehensive current proposals.
Divestiture window. Most proposals provide a 6 to 12-month transition period for members to sell individual stock holdings or transfer them to qualified blind trusts. Based on GovGreed's data, 343 active traders would be affected. Members who only hold diversified index funds or Treasury securities would not need to act.
Blind trust requirements. Qualified blind trusts must be approved by the relevant ethics committee and managed by an independent trustee. The member cannot communicate about holdings, and the trustee has full discretion over buy/sell decisions. This model already exists for executive branch officials, including the President and Cabinet members.
Allowed investments. Most ban proposals would still permit holdings in diversified mutual funds, index funds (such as S&P 500 ETFs), Treasury securities, and certain government bonds. The goal is to eliminate stock-picking where informational advantage applies, not to prevent all investment.
Market impact. The direct impact on stock prices would likely be minimal. Congressional trading volume, while large in absolute terms, is small relative to total market volume. The most-traded stocks by Congress (MSFT: 2,100 trades, AAPL: 1,873 trades, AMZN: 1,293 trades) have deep liquidity. The more significant effect would be the removal of informed congressional order flow from the market.
Historical precedent. The executive branch already operates under similar restrictions. Senior White House staff, Cabinet members, and federal judges are subject to divestiture requirements. The Defense Department prohibits senior officials from holding stocks in defense contractors. A congressional trading ban would align legislative branch ethics with existing executive branch standards.
