A $350B defense increase is riding on a reconciliation bill unlikely to pass as written. The exposure is concentrated: a handful of programs and two primes carry most of the mandatory dollars. A reading of what is at risk in the FY27 request for defense capital allocators.
President Trump's push for a $350 billion defense increase rests on a reconciliation bill that is unlikely to pass in its current form. Defense spending is rising across public and private portfolios. The question for investors is narrower: which specific programs and themes lose their funding if that bill stalls. Here is where the exposure sits.
Reconciliation is a special process that allows expedited consideration of specified changes to spending, revenue, and the debt limit, in order to align them with agreed budget targets. The legislation moves under the same expedited terms as a budget resolution: simple-majority passage, limited debate, and a restricted amendment process. It cannot be blocked by a Senate filibuster.
House Republicans are assembling a third reconciliation bill, often called Reconciliation 3.0. The House Budget Committee and Speaker Mike Johnson are negotiating the agenda, and the effort faces real obstacles.
For public market allocators, the finding is concentration. The heightened risk sits with two companies, Lockheed Martin (ticker LMT) and RTX Corporation (ticker RTX), because the mandatory dollars are pooled within them. Lockheed Martin anchors PAC-3/MSE, THAAD, the F-35 airframe, JASSM, SMRF, and the Aegis combat system. RTX anchors SM-6, Tomahawk, AMRAAM, the Aegis interceptors, the F-35 engine through Pratt & Whitney, and a large share of next-generation missile defense.
Private companies are not insulated. Two privately held entrants show why: Castelion's Multi-Mission Affordable Capacity Effector (MACE) line draws 53% of its FY27 funding from the mandatory request, and Zone 5 Technologies' Family of Affordable Mass Munitions (FAMM) draws 38%.
A large share of the mandatory request is concentrated in a handful of capability themes that line up with active private and public investment areas: autonomous systems and drones (Drone Dominance, $53.6 billion), defense artificial intelligence (AI) infrastructure and compute (Sovereign AI Infrastructure, $46.0 billion), homeland and missile defense (Golden Dome for America, $17.5 billion), critical minerals and the National Defense Stockpile (NDS, $48.7 billion), and defense industrial-base financing through the Office of Strategic Capital (OSC, $20.0 billion in credit subsidy).
Allocators with positions in autonomy, defense AI and compute, missile defense, or critical minerals should track the reconciliation process closely, because a meaningful portion of the FY27 demand signal in each of these areas is carried by the mandatory request. If reconciliation fails or is materially delayed, the consequences for portfolio companies would likely include opportunities that never materialize, deferred awards, slower revenue ramps, and compressed valuations for businesses whose near-term growth is underwritten by these accounts.
The programs below carry the largest mandatory dollar exposure in FY27.
Program abbreviations: Patriot Advanced Capability-3 Missile Segment Enhancement (PAC-3/MSE); Terminal High Altitude Area Defense (THAAD); Aegis Ballistic Missile Defense (BMD); Standard Missile-6 (SM-6); Advanced Medium-Range Air-to-Air Missile (AMRAAM); Joint Air-to-Surface Standoff Missile (JASSM); Strategic Mid-Range Fires, also known as Typhon (SMRF); Medium Landing Ship (LSM); and Satellite Communications (SATCOM). Stock tickers appear in parentheses for the listed primes.
PAC-3/MSE, THAAD, Hypersonic Defense, AMRAAM, SMRF, and LSM. For this group, a reconciliation failure does not trim the FY27 plan, it removes it. These are the highest-conviction names for an at-risk thesis.
F-35, Aegis BMD, SM-6, Tomahawk, SATCOM, JASSM, and C-130J. A discretionary floor keeps the program of record alive, so what is at risk is the surge, the production-rate increase on which the current investment thesis depends. F-35 is the clearest case. It carries the largest single mandatory exposure at $12.3 billion, yet a substantial discretionary base remains, so the realistic downside is a slower ramp rather than a program in question.
The Columbia Class Ballistic Missile Submarine ($16.2 billion total, 1% mandatory), the Gerald R. Ford Class aircraft carrier, the San Antonio Class and America Class amphibious ships, the Arleigh Burke Class destroyer at 9%, and nearly every fighter and ground-vehicle line outside the surge. For these programs, a reconciliation failure barely registers.
If the bill stays expansive and carries broad policy measures like the SAVE Act, the likelihood of passing is very small. A narrower package, with a smaller defense increase and limited election-security grants to states, would stand a better chance in both chambers and would be less likely to get stripped out under Senate budget rules. Outside reconciliation, defense funding would need to pursue the increase through regular appropriations or an emergency supplemental, and both routes require 60 votes in the Senate.
The far larger discretionary budget is already moving through regular appropriations, and those dollars are not locked in either. As markups and conference negotiations play out, the numbers can still shift.
