Global Quantum Computing Market Size for 2025 Splits From $1.44B to $3.52B Across Analyst Firms
Four analyst firms tracking the same nominal global quantum computing market landed on 2025 valuations ranging from $1.44 billion to $3.52 billion -- a 2.4x spread with no visible convergence trend. The gap traces to inconsistent scope definitions: some trackers count hardware-only revenue, others fold in software, services, and adjacent quantum-communications spend. All four project rapid growth through the early 2030s, but they cannot agree on where the market stands today.
Findings
- MarketsandMarkets values the 2025 global quantum computing market at $3.52B, projecting a 41.8% CAGR to $20.20B by 2030.
- Precedence Research puts the same 2025 baseline at $1.44B -- less than half MarketsandMarkets figure -- reaching $19.44B by 2035 at a 29.73% CAGR.
- Grand View Research and Market.us land in between, at $1.6B and $2.2B respectively, each citing different regional and segment scope as a driver of the gap.
- The four 2025 estimates span a 2.4x range ($1.44B-$3.52B) despite all four firms nominally tracking the same current-year market, not a long-range forecast where disagreement would be more expected.
