Defense is the most government-shaped industry in America. Some of the lawmakers who control that spending are also investors.
An $852 billion annual defense budget flows entirely through congressional authorization and appropriation. The members who decide where that money goes are legally permitted to hold stock in the companies that receive it. Most of those decisions happen behind closed doors.

Why defense is categorically different from every other sector
Most industries have some relationship with the federal government. Healthcare companies negotiate CMS reimbursements. Tech companies face FTC scrutiny. Banks operate under Federal Reserve oversight. But in all of these sectors, the government is one actor among many. Private demand, market competition, and consumer behavior set the majority of revenue, pricing, and opportunity.
Defense is structurally different. The U.S. government is not a major customer of the defense industry. It is effectively the only customer. Lockheed Martin generates 73% of its $71 billion in annual revenue directly from U.S. government contracts. Northrop Grumman's figure is 87%. General Dynamics sits at 69%. These companies exist, in their current form, because Congress authorizes and appropriates the money to pay them. Their revenue is not a function of consumer demand, market competition, or product-market fit. It is a function of decisions made in closed-session committee markups on Capitol Hill.
This creates a structural information asymmetry unlike anything in the private economy. Before Lockheed Martin knows whether the F-35 program will be funded at the requested level, cut, or expanded, Armed Services Committee members have already voted on it in closed session. Before RTX knows whether a Patriot missile contract will be awarded to replenish Ukraine-depleted stockpiles, Appropriations subcommittee members have already reviewed the funding line. Before Northrop Grumman's stock reflects a new missile defense initiative, Intelligence and Armed Services committee members have been briefed on the classified components of the program.
The STOCK Act of 2012 requires members to disclose trades within 45 days but does not prohibit congressional stock ownership in sectors under their direct oversight. A senator on the Armed Services Committee who receives a classified briefing on the defense budget and then purchases Lockheed Martin stock is acting legally under current law, as long as no single classified document can be proven to have served as direct investment advice. The gaps in that law apply equally to defense as to every other sector. In defense, the magnitude of the potential information advantage is larger, because no other industry is so completely dependent on a single decision-maker: Congress itself.
The five committees that control the defense budget
Not all committee assignments carry equal weight for defense sector investing. These five have direct jurisdiction over the funding, authorization, and oversight of every major defense program and contractor.
Senate Armed Services Committee (SASC)
Primary authorization authority for all U.S. military programs
The SASC authorizes the National Defense Authorization Act (NDAA), the single most consequential piece of legislation for defense contractor revenue. Its 27 members authorize funding levels for every major weapons program: the F-35, the B-21 Raider, the nuclear triad, hypersonic weapons development. Crucially, most SASC subcommittee markups are conducted in closed session. Members vote on classified annexes covering sensitive acquisition programs that the public cannot see. They receive regular briefings on active procurement competitions, program performance issues, and contract negotiation status. When a program's funding level is cut, expanded, or redirected during markup, those members know the direction of contractor revenue months before public disclosure.
House Armed Services Committee (HASC)
House counterpart with 57 members and the same authorization jurisdiction
The HASC mirrors the SASC's authorization function on the House side. With 57 members across seven subcommittees (including Tactical Air and Land Forces, Seapower and Projection Forces, and Strategic Forces), it has the largest total membership of any defense oversight committee. Its subcommittee markups are similarly conducted in closed session. The HASC also oversees the Missile Defense Agency, Special Operations Command, and cybersecurity programs. Members receive the same closed briefings on program trajectories and contract status. The HASC and SASC conference their competing NDAA versions each fall, giving members of both committees advance visibility into the final funding decisions before public text is released.
Senate and House Appropriations Subcommittees on Defense
Where the actual money is appropriated: procurement, operations, research funding
Authorization and appropriation are separate legislative functions. The SASC and HASC authorize programs; the Appropriations subcommittees provide the actual funding. The Senate Defense Appropriations Subcommittee controls program-by-program funding in the Procurement, Research and Development, and Operations and Maintenance accounts. The subcommittee chairman's mark, prepared in closed session, contains specific line-item funding levels for individual weapons programs and contractor payments. Members of these subcommittees know which production programs will be funded at what quantities and which R&D lines are being cut, before contractors or markets do. The late Senator Richard Shelby, who chaired the Senate Appropriations Committee, became the defining example of how much defense money a single appropriator can direct: he secured more than $548 million in Alabama-specific defense projects in the FY2022 omnibus alone, including $10.3 billion for the Missile Defense Agency headquartered in Huntsville.
Senate and House Intelligence Committees
Black budget programs, classified AI contracts, Special Access Programs
The intelligence committees (the Senate Select Committee on Intelligence and the House Permanent Select Committee on Intelligence) oversee the classified components of the defense budget, including Special Access Programs (SAPs) that are not disclosed in any public document. They receive the most highly classified briefings in Congress: threat assessments, covert program status, intelligence community procurement priorities, and the classified layer of defense AI. The growth of defense AI spending has made these committees increasingly relevant to defense contractor investing. Contracts for AI systems deployed by NSA, CIA, and military commands flow to companies like Palantir, which in March 2026 was formally designated as the Pentagon's primary AI platform across all five military branches. Intelligence committee members who also hold positions in these companies occupy perhaps the most acute conflict-of-interest position in Congress.
Senate Foreign Relations / House Foreign Affairs
Foreign military sales, export licenses, Ukraine supplemental packages
Defense contractors do not sell only to the U.S. government. Foreign military sales (FMS) represent a significant and growing share of Lockheed, RTX, and General Dynamics revenue. State Department export licenses for weapons sales to foreign governments are reviewed with the Foreign Relations and Foreign Affairs committees. Before Ukraine war supplemental packages were made public, members of these committees knew the approximate composition and scale of what was being transferred, and therefore which contractors would receive replenishment orders. RTX, whose Stinger and Javelin production was activated at scale starting in early 2022, was a direct beneficiary of decisions that committee members had advance knowledge of.
Four moments when government decisions moved defense stocks
These are specific government actions that created information asymmetry between congressional committee members and ordinary investors. Each one is documented. Each type will happen again.
The B-21 Raider contract award (October 2015)
On October 27, 2015, the Air Force announced Northrop Grumman as the winner of the Long Range Strike Bomber contract, beating a competing Boeing-Lockheed team. The initial contract was worth $21.4 billion; the total program, for 100 aircraft, was estimated at $79.2 billion. Northrop's stock rose approximately 30% over the full year of 2015, the year in which the contract evaluation was ongoing. The Boeing-Lockheed team filed a GAO protest that was subsequently denied. Members of the Armed Services and Appropriations committees who had been briefed on the program evaluation had access to the direction of that decision before the announcement. Lockheed and Boeing declined on announcement day. For investors who knew the outcome in advance, the trade was unambiguous. For those who did not, it was a surprise. The B-21 would become Northrop's defining future program, representing the most consequential single contract award in U.S. defense procurement in a decade.
The Ukraine invasion and the restocking surge (February 2022)
Russia's invasion of Ukraine on February 24, 2022 was the most powerful single catalyst for defense stocks in a decade. Lockheed Martin rose nearly 40% between late December 2021 and late February 2022. RTX rose more than 25% over the same period. For the full year following the invasion, top defense stocks outperformed the S&P 500 by 17.82 percentage points and the Nasdaq by 23.88 points.
The question is what committee members knew before the public. Intelligence and Armed Services committees received classified briefings on the Russian military build-up beginning in late 2021. The Biden administration briefed Congress on the invasion threat in closed sessions weeks before February 24. Members on these committees understood both that an invasion was likely and that U.S. policy would involve large weapons transfers (Javelins, Stingers, HIMARS) that would deplete existing stockpiles and require replenishment contracts. The contracts arrived as informed observers would have expected: a $624.6 million Stinger contract to Raytheon in May 2022, multiple Javelin contract modifications totaling hundreds of millions, and a $521 million HIMARS replenishment deal for Lockheed Martin.
The F-35 delivery hold (mid-2023 to July 2024)
The F-35 program alone represents approximately 26% of Lockheed Martin's total annual revenue, making it the single most consequential program in the entire U.S. defense budget for any individual contractor. From mid-2023 to July 2024, Lockheed was unable to deliver F-35s due to problems with the TR-3 (Technology Refresh-3) hardware and software configuration. The hold disrupted revenue recognition for more than a year and created prolonged uncertainty around the Lot 18 and Lot 19 contract negotiations (296 aircraft ultimately priced at $24.29 billion combined, representing an average of $82.4 million per airframe). Armed Services and Appropriations committee members, who receive regular program status briefings, knew the severity and timeline of the TR-3 problem well before investors processing public information. The resolution came in July 2024 when deliveries resumed. The timing and trajectory of the entire delay were subjects of closed committee briefings throughout.
Golden Dome and the next missile defense cycle (2025 onward)
President Trump announced the Golden Dome missile defense initiative in early 2025. The FY2026 defense appropriations bill included $13.4 billion in initial funding. The Pentagon subsequently raised its total spending plan to $185 billion, with independent estimates from Bloomberg reaching up to $1.1 trillion for a fully operational system. Northrop Grumman, Lockheed Martin, and RTX are all part of the initial contractor consortium. More than 1,000 companies have been designated as qualifying offerors for future awards. The shape of Golden Dome: which contractors receive which contracts, what technologies are prioritized, and what the final program scope will be, is being determined in classified Armed Services and Intelligence committee briefings that are months ahead of any public announcement. For members of those committees who hold positions in the contractors involved, the information advantage is structural and ongoing.
Committee members and the defense stocks they oversee
The abstract conflict of interest becomes concrete when you look at specific documented cases. None of the individuals below has been charged with any crime. They are cited because they illustrate the specific dynamic at work: committee oversight of a sector combined with personal investment in that sector, enabled by a disclosure law with limited enforcement teeth.
Sen. Tommy Tuberville (R-AL) — Armed Services Committee
Tuberville has been among the most active defense stock traders in the Senate during his time on the Armed Services Committee. He holds stock in Lockheed Martin and reported between $63,007 and $245,000 in defense-related stock trades in 2024 alone. In September 2023, he participated in a Senate Armed Services Committee hearing with Lockheed Martin CEO James Taiclet while holding Lockheed stock. The Project on Government Oversight described the situation as "a textbook example of a conflict of interest." When asked about proposed restrictions on congressional trading, Tuberville responded that they would be "ridiculous" and would "cut back on that amount of people who would want to serve in Congress." He had previously violated the STOCK Act by failing to timely report approximately 130 transactions in 2021, incurring nominal penalties.
Rep. Ro Khanna (D-CA) — Armed Services Committee
Khanna reported more defense-related trades than any other member of the House Armed Services Committee over the 2021-2022 period. The trades were made through trusts in the names of his wife and children and spanned all five of the largest defense contractors: Lockheed Martin, Raytheon, Boeing, General Dynamics, and Northrop Grumman. In January 2022, during the period when Congress was receiving classified briefings on the Russian military build-up along the Ukrainian border, his wife's trust purchased up to $50,000 worth of General Dynamics shares. Khanna has been one of the most vocal congressional advocates for a stock trading ban and has introduced legislation to that effect, though it has not passed.
Rep. Pat Fallon (R-TX) — Armed Services Committee
Fallon sold up to $250,000 worth of Microsoft stock two weeks before the Pentagon publicly announced it was canceling a $10 billion cloud computing contract with Microsoft. Fallon served on the Armed Services subcommittee with oversight of that contract. His spokesperson stated he had "absolutely no prior knowledge" of the cancellation. No investigation or charges followed. The episode demonstrates how the STOCK Act's enforcement structure means that even transactions with a clear temporal relationship to closed committee information produce no legal consequence. The law requires disclosure after the fact; it provides no mechanism to investigate whether undisclosed information informed the timing.
These cases are not outliers. A 2022 New York Times investigation found at least 8 members of the House Armed Services Committee holding aerospace or defense contractor stocks. A broader analysis identified at least 50 U.S. lawmakers or their household members holding financial stakes in military contractors, with combined estimated holdings reaching up to $10.9 million. Among the most active congressional stock traders, multiple members sit on the committees that directly authorize and appropriate defense spending.
What makes a defense trade worth examining
Most congressional purchases of defense contractor stocks are noise: routine portfolio activity, inherited positions, or broad-index-like accumulation. These are the characteristics that distinguish a trade worth scrutinizing from one that is not.
Committee assignment matches the contractor
An Armed Services Committee member buying Lockheed Martin is categorically different from an Agriculture Committee member buying the same stock. The former authorizes the programs that generate Lockheed's revenue and receives classified briefings on contract status. The information asymmetry is structural, not incidental. See the full committee conflict-of-interest breakdown for how this applies across all sectors.
Timing relative to the NDAA markup cycle
The defense budget process follows a predictable annual calendar. The President's budget request arrives in February. SASC and HASC subcommittee markups occur in April through June, in closed session. Full committee votes follow in early summer. Trades made by committee members in the April-to-June markup window occur with full knowledge of what the committee is voting on for specific programs.
Timing relative to specific program events
Trades placed in the weeks surrounding a major contract award, program modification, or budget line change carry different weight than routine accumulation in a quiet period. An Armed Services Committee member buying RTX in the week before a Patriot contract modification is announced, or selling Lockheed in the weeks before a program cut becomes public, represents the specific dynamic the STOCK Act was originally intended to address.
Position size bracket
Congressional disclosures use amount brackets rather than exact figures. A $1,001 to $15,000 purchase is ambiguous and may be routine. A $500,001 to $1,000,000 or a $1M-plus purchase from a committee member in a sector they directly oversee is a different order of signal entirely.
New position versus existing holding
A member who has held General Dynamics for a decade adding a small position is different from a fresh purchase in a company they have never held before, opened during closed markup season. Historical trade patterns provide essential context. A brand-new position in a contractor the member has no previous holding in, opened in the weeks before a contract announcement, carries maximum signal weight.
Cluster trades across committee members
A single trade from one committee member can be coincidence. Multiple members of the Armed Services or Intelligence committees purchasing the same contractor in a narrow window reflects a shared information environment. When several senators from the same subcommittee accumulate positions in the same defense company in the same quarter, the most parsimonious explanation is a shared closed-session briefing, not simultaneous independent investment decisions.
The revolving door: stock trading is only part of the picture
Congressional stock trading is only one dimension of the financial relationship between defense committee members and the industry they oversee. The other dimension is post-congressional employment. A 2023 report by Senator Warren ("Pentagon Alchemy") found 672 instances in a single year (2022) of former high-ranking Pentagon officials and members of Congress working as lobbyists, board members, or executives for the top 20 defense contractors. Boeing had hired 85 such individuals; Raytheon had 64; General Dynamics 57; Lockheed Martin 53.
The most documented individual case involves former House Armed Services Committee Chairman Howard "Buck" McKeon, who served as chairman from 2011 to 2014. His career campaign contributions included $192,900 from Lockheed Martin and $190,200 from Northrop Grumman. After leaving Congress, he founded the McKeon Group lobbying firm, which immediately signed Lockheed, Northrop, General Dynamics, and L3 Technologies as clients. By 2023, Lockheed alone was paying the McKeon Group $155,000 annually. The firm also represented the Kingdom of Saudi Arabia and lobbied against restrictions on U.S. arms sales to foreign governments.
Current law imposes a 1-year cooling-off period on former House members and a 2-year restriction on former senators before they can directly lobby their former colleagues. These rules contain a significant structural gap: they apply only to direct "lobbying contacts," meaning the actual communication with officials. A former committee chairman can immediately join a lobbying firm, design the entire strategy, prepare all the materials, direct the lobbying team, and attend every planning meeting. Only the final phone call or meeting with a member requires someone else to make it. Senator Warren's proposed Department of Defense Ethics and Anti-Corruption Act would have imposed a four-year ban and extended general officer restrictions to four years. It did not advance to a vote.
The structural result is that an Armed Services Committee member spends years overseeing defense contractors, voting on their programs in closed session, receiving classified briefings on their contract status, and building relationships across the industry, with the knowledge that the same contractors will be significant potential employers or clients after they leave. This future employment dynamic creates a long-term financial incentive that stock trading disclosure rules do not address at all. It is one reason why political intelligence in the defense sector extends well beyond the simple act of buying or selling a stock before an announcement. For the same analysis applied to the energy sector, where federal land leasing, LNG export permits, and clean energy tax credits create comparable information advantages, see: Congress and energy stocks.
Frequently asked questions
Yes, under current law. The STOCK Act of 2012 prohibits trading on material non-public information but does not ban congressional stock ownership or trading in sectors under direct committee oversight. Members of the Armed Services and Appropriations committees can buy and sell Lockheed Martin, RTX, Northrop Grumman, General Dynamics, or L3Harris while simultaneously sitting on committees that authorize those companies' contracts, receiving classified briefings on their program status, and voting on the budgets that fund them. The only legal requirements are disclosure within 45 days and that no specific classified document can be proven to have directly motivated the trade. Multiple reform bills would change this. None has passed.
The NDAA goes through a months-long process before becoming law. The President's budget request arrives in February. SASC and HASC subcommittee markups occur from April through June, in closed session, where members vote on specific program funding levels, additions, and cuts, including a classified annex covering sensitive programs. Full committee markup follows in summer, then a bicameral conference to reconcile differences, then floor votes. Between February and December of any given year, committee members have voted on, and therefore know, the funding trajectory of hundreds of specific defense programs. The companies whose revenues depend on those programs have not yet received any public signal. Any stock trades by committee members during the spring markup window occur with full advance knowledge of the direction of spending.
Northrop Grumman is the most government-dependent of the major contractors, with 87% of its $41 billion in 2024 revenue coming from U.S. government contracts. Its core programs (B-21 Raider, LGM-35 Sentinel ICBM, nuclear submarine systems) have no commercial equivalent and would not exist without ongoing congressional authorization. Lockheed Martin is second, with 73% government dependency, driven by the F-35 program alone representing 26% of total revenue. General Dynamics sits at 69%. RTX is more diversified due to its Collins Aerospace commercial aviation segment, but its Raytheon division covering missiles and air defense is almost entirely government-funded. Palantir, while smaller than the legacy primes, now generates approximately 50% of its revenue from U.S. government contracts, growing at 45% year-over-year in government revenue as of early 2025.
Yes. Ukraine supplemental packages were assembled in consultation with Armed Services and Foreign Relations committee members before public announcement. The composition of weapons being transferred (Javelins, Stingers, HIMARS) and the resulting need to replenish U.S. stockpiles at scale was known to committee members before contracts were placed. Raytheon received a $624.6 million Stinger contract in May 2022; Lockheed received a $521 million HIMARS replenishment contract; Javelin modifications totaling hundreds of millions followed. Defense stocks collectively outperformed the S&P 500 by 17.82 percentage points in the year following the invasion. Members of the committees that assembled and authorized the aid packages were in a structurally advantaged position to anticipate the restocking windfall, well before the market priced it in.
Congressional trade disclosures are public records filed as Periodic Transaction Reports (PTRs) under the STOCK Act, posted to the House Clerk and Senate Secretary disclosure portals. In practice, finding and contextualizing them requires significant manual effort. A raw disclosure tells you a member bought Lockheed Martin in a $50,001 to $100,000 bracket. It does not tell you whether that member sits on the Armed Services Committee, whether the disclosure was filed late, or whether the timing overlaps with a closed subcommittee markup. Kapitol.ai curates these disclosures with committee context and insider significance scoring, so you see the trades that matter without manually cross-referencing committee rosters against disclosure filings.
