IBM announced plans on April 28, 2025, to invest $150 billion in the United States over five years. More than $30 billion of that amount, the company said, would support research and development tied to American manufacturing of mainframe and quantum computers. The full $150 billion was not earmarked for those two technologies, and IBM has not published a detailed spending schedule or a tally of how much it has spent under the plan.
What IBM actually pledged
IBM described a broad, five-year U.S. investment plan—not a single factory project or a government-funded construction program. In its April 28, 2025 announcement, it said it planned to invest $150 billion in the United States and that more than $30 billion would go toward R&D to advance and continue American manufacturing of mainframe and quantum computers.
| Figure or commitment | What it means |
|---|---|
| $150 billion over five years | IBM’s total announced U.S. investment plan across its activities; not an amount designated entirely for factories, mainframes, or quantum computers. |
| More than $30 billion | The portion IBM specifically associated with R&D supporting American mainframe and quantum manufacturing. |
| Poughkeepsie, New York | An existing IBM mainframe manufacturing center that the company said would remain central—not a newly announced greenfield facility. |
IBM did not break down the remaining investment into specific amounts for software, cloud infrastructure, data centers, acquisitions, payroll, or capital spending. Nor did the announcement provide a year-by-year schedule, facility-by-facility budget, construction commitment, or a number of new jobs. The five-year period points roughly from 2025 to 2030, but the release did not publish a detailed calendar.

What “U.S.-based production” means—and does not mean
IBM said it would continue manufacturing advanced mainframes in Poughkeepsie and would continue to design, build, and assemble quantum computers in the United States. Those are meaningful manufacturing and engineering commitments, but they do not establish that every component is made domestically.
#1 Best Overall
A quantum computer is a full system, not just a processor. Its production can involve processor design and fabrication, packaging, control electronics, cryogenic equipment, system assembly, and software. IBM’s statement supports its intention to design, build, and assemble systems in America; it does not promise that every chip, material, or supply-chain input will be U.S.-sourced. Likewise, maintaining work at Poughkeepsie does not by itself prove that IBM is building a new plant there.
The distinction matters when judging the economic impact. Domestic assembly and R&D can strengthen U.S. technical capacity and supply-chain resilience without meaning that the entire supply chain—or all $150 billion—is domestic manufacturing expenditure.

Why mainframes remain part of the investment
Mainframes are still used for high-volume, dependable transaction processing in sectors such as banking, insurance, government, retail, and telecommunications. IBM says more than 70% of the world’s transactions by value run through IBM mainframes manufactured in the United States. That is IBM’s own claim, not an independently verified statistic in the announcement.
The pledge also came shortly after IBM introduced the z17, which the company positioned for enterprise AI workloads. Contemporary reporting said general availability was scheduled for June 18, 2025; that is historical launch context, not a statement about current availability. See IBM’s z17 announcement.
For customers, continued U.S. manufacturing may be relevant to supply continuity and long-term support planning. It does not guarantee lower prices, faster delivery, or a particular product roadmap. Mainframe buyers still need to assess modernization costs, application compatibility, staffing and skills, security requirements, and how IBM Z fits into a hybrid-cloud architecture.
Quantum computing is a longer-term bet
IBM’s quantum investment concerns research, hardware development, system production, and the ecosystem around access and experimentation. At the time of the 2025 announcement, IBM said its Quantum Network offered access to its systems for nearly 300 Fortune 500 companies, academic institutions, national laboratories, and startups, and that more than 600,000 active users had accessed it. These are IBM-provided figures tied to the announcement, not a current user count.
Access to quantum hardware through a network or cloud platform is not the same as having a broadly useful, fault-tolerant computer that outperforms conventional machines on ordinary business workloads. IBM’s pledge is evidence of continued investment in a developing field, not proof that commercially useful general-purpose quantum computing has arrived or will do so within the five-year investment horizon.

The announcement is a public corporate plan supported by IBM’s established U.S. mainframe manufacturing presence and ongoing quantum program. It is not a legally binding government appropriation, a grant award, or a project-level construction contract. The release does not say how much of the total is incremental to spending IBM would otherwise have made, or how much is expected to be capital expenditure rather than other U.S.-based investment.
That means the pledge should be taken seriously as a stated direction, but not treated as a verified outcome. IBM has not specified guaranteed job creation, new facilities, domestic supplier targets, or annual spending milestones in the cited announcement. Its newsroom continues to list U.S.-based quantum and mainframe activity, but those announcements do not establish how much of the $150 billion has been spent or committed. Readers can check IBM’s corporate newsroom for subsequent announcements; a project update is not the same thing as a public accounting of the pledge.
What to watch for
To judge progress, look for evidence that can be connected to the headline commitment rather than relying on the original total alone:
- Annual spending disclosures that explicitly identify U.S. investment and clarify how the amounts are counted.
- Specific facility upgrades, expansions, or construction plans, including their location and funding.
- Hiring figures, supplier commitments, or production-capacity targets with clear timelines.
- Separate updates on mainframe manufacturing and quantum hardware milestones, rather than treating them as one program.
- Clear distinctions between new spending and projects or operating costs that were already planned.
For technology customers and investors, the announcement is a signal of IBM’s intended U.S. footprint, not a substitute for product, service, financial, or supply-chain due diligence. The practical question is whether later disclosures show measurable activity—and whether that activity affects the particular systems, services, or markets that matter to them.
