The 11-to-1 gap: $12.6 billion into quantum in 2025, just over $1 billion back
Quantum drew $12.6 billion of investment in 2025 against just over $1 billion of revenue. The gap marks the deployment layer as the open layer.
Quantum attracted $12.6 billion of investment in 2025 and returned just over $1 billion in revenue. The figures come from the McKinsey Quantum Technology Monitor, April 2026. Eleven dollars in for every dollar out, and that ratio is the most useful single number for reading the quantum market this year.
Where did the capital concentrate?
Per the same report, annual investment ran 6.3x year over year. Capital markets supplied 44% of the total, and the top 10 deals consumed roughly 60% of the year’s capital. Read together, those three numbers describe a hardware layer consolidating in real time: fewer, larger bets on the companies building the processors.
The deployment layer shows no such consolidation. No comparable concentration of capital, talent, or tooling exists at the layer where quantum work gets integrated into production systems. That asymmetry is the structural fact of the 2025 market.
Who is already paying for quantum work?
McKinsey counts more than 300 companies already paying for quantum work. The median use-case budget sits near $6 million, willingness to pay reaches about $13 million per use case, and 7% of buyers run programs above $200 million. The same report puts $1.3 to $2.7 trillion of value at stake across industries by 2035.
| Measure | Figure |
|---|---|
| Investment into quantum, 2025 | $12.6 billion |
| Quantum revenue, 2025 | just over $1 billion |
| Year-over-year investment growth | 6.3x |
| Share of investment from capital markets | 44% |
| Share of the year’s capital in the top 10 deals | roughly 60% |
| Companies already paying for quantum work | more than 300 |
| Median use-case budget | about $6 million |
| Willingness to pay per use case | near $13 million |
| Buyers running programs above $200 million | 7% |
| Value at stake across industries by 2035 | $1.3 to $2.7 trillion |

What is missing between capital and revenue?
Capital is committed. Buyers are committed. The layer that turns commitment into shipped use cases inside a single budget cycle is the one still missing at scale.
McKinsey’s integration framing points at where this resolves. Quantum compute belongs alongside CPU and GPU in the existing HPC stack, with software-defined layers routing workloads dynamically. On that reading, the QPU is a new accelerator inside a grid that already runs, and the work of the next phase is integration work: scheduling, routing, validation, and the operational plumbing that lets a quantum workload sit inside an existing compute budget.
That deployment layer is the un-consolidated layer of the quantum economy.
Why is 2026 the year this stops being speculative?
The sanity checks now sit outside the market itself. NIST has closed the PQC standards. The EU FS-PQC schedule is firm. US federal procurement is mandated to PQC by 2030. Each of those is a fixed point that does not move with sentiment, and together they put a calendar under decisions that used to float.
The window before the late-mover premium starts to compound is open and narrowing. Organisations that want to locate themselves on that calendar can start with the QR8 readiness scan, free and self-serve.
If a 2026 plan still treats quantum as a 2030 question, it is built on the wrong calendar.
