A bill to require the Secretary of Defense to support development of quantum technologies, and for other purposes.
Summary
Sen. Rounds and Sen. Blumenthal introduced a bill (S5139) requiring the DoD to support quantum technologies. The bill is in early stage, with no explicit funding, but it signals bipartisan congressional interest in accelerating quantum for defense. Pure-play quantum companies are the most direct beneficiaries.

Key Takeaways
- 1.S5139 is a bipartisan bill directing the DoD to support quantum technologies, but it remains in early legislative stages with no funding attached.
- 2.Pure-play quantum companies ($IONQ, $RGTI, $QBTS, $ARQQ) are the most direct beneficiaries due to their reliance on government contracts.
- 3.The bill does not yet guarantee spending; investors should monitor committee progress and potential appropriations riders.
Market Implications
The bill's introduction signals bipartisan support for quantum technology in defense, but without a funding mechanism, the near-term market impact is limited. Pure-play quantum stocks may see a sentiment boost, but no concrete revenue is guaranteed. The sector remains high-risk, high-reward, with valuations driven by contract wins. Investors should treat this as a long-term catalyst, not a near-term earnings driver.
Full Analysis
On July 27, 2026, Senators Mike Rounds (R-SD) and Richard Blumenthal (D-CT) introduced S5139, a bill to require the Secretary of Defense to support development of quantum technologies. The bill was read twice and referred to the Senate Committee on Armed Services, placing it at an early legislative stage. The bill does not appropriate a specific dollar amount; it is an authorization that would direct the DoD to prioritize quantum R&D and integration. Future funding would require a separate appropriations process.
The money trail: The bill instructs the Secretary of Defense to establish programs, contracts, and grants to advance quantum technologies. While no dollar figure is specified, the DoD's annual R&D budget includes tens of billions for advanced technologies. If passed, this bill would likely lead to increased allocations for quantum computing, sensing, and communications within the Defense Advanced Research Projects Agency (DARPA) and the military services.
Convergence: There are no other related signals or executive orders directly connected to this bill within the provided data. The recent executive order on defense supply chains is unrelated to quantum. Therefore, the bill stands alone as a catalyst for the quantum technology sector.
Structural winners: Pure-play quantum computing companies such as IonQ ($IONQ), Rigetti Computing ($RGTI), D-Wave Systems ($QBTS), and Arqit Quantum ($ARQQ) are the most directly exposed. These companies generate a significant portion of their revenue from government contracts and are positioned to benefit from any DoD push to adopt quantum solutions. Defense primes like Lockheed Martin ($LMT) and Northrop Grumman ($NOC) may also participate as integrators, but the impact is more diffuse for them.
Timeline: As a referred bill, it must pass committee markup, then a full Senate vote, and then a House companion bill (if any) before reconciliation and presidential signature. The 119th Congress runs through 2027, so passage is possible but not certain. The bipartisan sponsorship increases the odds of committee action.

No confirming evidence found yet from contracts, insider trades, or congressional activity
What the bill does
Mandate for Secretary of Defense to support development of quantum technologies through R&D, procurement, and integration into defense systems.
Who must act
Department of Defense (DoD) – specifically the Office of the Secretary of Defense for Research and Engineering and the Defense Advanced Research Projects Agency (DARPA).
What happens
Increased DoD R&D contracts and grants for quantum computing hardware and software, with potential for procurement of quantum systems for defense applications such as optimization, simulation, and cryptography.
Stock impact
IonQ is a pure-play quantum computing company focusing on trapped-ion quantum systems. As a leading provider of quantum hardware and cloud-accessible quantum processors, it is positioned to receive DoD contracts and grants for quantum computing research and development. IonQ's revenue from government contracts is a significant portion of its total revenue, and this bill would directly expand that opportunity.
What the bill does
Same as above – DoD mandate to support quantum technologies.
Who must act
DoD research and procurement offices.
What happens
Increases likelihood of government contracts for quantum computing hardware and software, particularly for defense-specific applications like quantum sensing and secure communications.
Stock impact
Rigetti Computing designs and manufactures superconducting quantum processors and offers quantum cloud services. The DoD's interest in quantum computing for defense could lead to contracts for quantum hardware development and integration into defense systems. Rigetti's current revenue is heavily government-dependent, making it highly sensitive to this bill.

Adjusting Imports of Unmanned Aircraft Systems and Unmanned Aircraft Systems Components into the United States
This proclamation imposes a 100% ad valorem tariff on imports of unmanned aircraft systems (UAS) over 25 kg, those with thermal imagers, docking stations, and certain components, and a 25% tariff on UAS under 25 kg and other components, citing national security under Section 232 of the Trade Expansion Act. It also authorizes the Department of Commerce to establish an onshoring program offering preferential tariff treatment for companies that build new U.S. manufacturing facilities for UAS and components.
Rebuilding the United States Navy and America’s Shipbuilding Industrial Base
This memorandum directs the Secretary of War to replace the Electromagnetic Aircraft Launch System with steam/hydraulic systems on aircraft carrier CVN-81, adopt a 'Finland Model' allowing foreign shipbuilders to bid on up to three ship classes if they build U.S. shipyards and transfer technology, and submit plans for a fifth public Navy yard, a component repair center, and competitive acquisitions for surface combatants and auxiliary vessels. It also restricts iterative design changes and delegates waiver authority for foreign shipbuilding contracts.
Expanding Capabilities to Combat Transnational Cyber-Enabled Crime
This memorandum establishes a government program, managed by the National Coordination Center (NCC), that authorizes private companies to conduct cyber surveillance and operations against foreign cyber-enabled transnational criminal organizations under federal oversight. It directs the Department of Justice and Department of Homeland Security to co-execute the program, requiring vetted companies to enter contracts with the government and potentially post a $1 million bond, with implementation guidance to be developed within 60 days.
