Venture capital investment in quantum computing hit an all-time high in 2025, with $3.9 billion deployed across 125 deals worldwide. This marked the largest annual total on record and signaled a clear turning point for the sector. PitchBook states that the surge continued into early 2026. The first quarter alone saw $1.2 billion in new commitments before activity moderated somewhat at the start of the second quarter, a pattern often seen after periods of heavy, large-scale deployment.
PitchBook further noted in the research report that one of the clearest trends was the growing concentration of capital in bigger rounds.
Deals of $25 million or more accounted for roughly $3.5 billion in 2025—about four times the level seen in the prior year.
Median deal size reached $90 million, reflecting stronger conviction in companies that have advanced further along their technical roadmaps.
Stage composition also shifted sharply. The share of funding going to venture growth rounds climbed from around 1 percent in 2024 to 30.4 percent in 2025.
Late-stage and growth capital now dominate deal value, while smaller early-stage checks have become relatively less prominent in the overall picture.
Geographically, North America captured 52.5 percent of total deal value, with Europe accounting for another 33.6 percent.
Combined, these two regions represented the vast majority of global quantum computing investment.
Europe, in particular, continued to support a broad base of earlier-stage activity.
Several standout financings drove the 2025 totals.
PsiQuantum closed a $1 billion round in September 2025 at a $6 billion pre-money valuation.
Quantinuum followed with an $838.85 million raise in November 2025 at a $10 billion pre-money valuation.
Other notable rounds included IQM Finland’s $372 million financing in August 2025 and Pasqal’s $236.91 million round in February 2026. Institutional and strategic investors have become increasingly active.
Leading participants by capital deployed in recent years include NVIDIA, BlackRock, Baillie Gifford, and several sovereign wealth funds.
Their involvement underscores the sector’s transition from a niche specialty area into one attracting mainstream institutional allocations. Public-sector support remains a major pillar.
Cumulative government commitments to quantum technologies now exceed $60 billion globally, with funding increasingly directed toward commercialization and industrial applications rather than pure research.Exit activity also accelerated.
In the first quarter of 2026 alone, four transactions generated $5.7 billion in exit value. Highlights included Xanadu’s $2.825 billion reverse merger in March 2026 and Infleqtion’s $1.675 billion deal in February 2026.
According to insights from PitchBook, the sector now sits at an inflection point shaped by faster technical progress in error correction, intensifying global competition, and deeper public-private collaboration.
The next two to three years are widely viewed as decisive in determining which companies will lead and where commercialization efforts will concentrate most strongly. The PitchBook research report has now concluded that on current trajectories, quantum computing is expected to begin generating meaningful commercial revenue within the decade.
