March 2026 was a headline month for London startup funding. Strip out one mega-round and the picture looks different: 44 deals shared £644m.

Key takeaway

Strip out one deal and London's £2.14bn VC month becomes a £644m one across 44 rounds.

London startups raised £2.14bn across 45 deals in March 2026, up 21% year-on-year 1. Six late-stage deals captured £1.88bn, or 87.7% of the month's total. Nscale alone accounted for roughly £1.5bn, approximately 70% of everything raised. Excluding Nscale, the remaining 44 deals raised £644m.

AI companies took 88% of capital across 22 of 45 deals, but two-thirds of that AI allocation was a single cheque. At the early stage, 28 deals raised £106m total, with a median deal size of £1.9m. That is healthy deal volume but modest scale.

The distribution tells the story more clearly than the headline. UK AI funding is bifurcated: a handful of mega-rounds at the top, a large field of small rounds at the bottom, and very little in between. A seed-stage founder raising £2m is operating in a different capital market from a growth-stage company raising £200m. The headline number of £2.14bn creates an impression of abundance that the median founder does not experience.

Deep Analysis

In plain English

London tech companies raised £2.14bn from investors in March 2026, which sounds like a lot. But one company, Nscale, accounted for £1.5bn of that on its own. Remove Nscale from the total, and the remaining 44 companies raised £644m between them. For small, early-stage companies, 28 deals were done at an average of about £3.8m each. That is the part of the market that matters most for founders just starting out, and those numbers look stable rather than exceptional.

What could happen next?
  • Consequence

    Headline UK VC figures in 2026 will be systematically inflated by AI mega-rounds, making it difficult to assess underlying early-stage ecosystem health without normalising for outliers.

Different Perspectives
European limited partners (Plural, Aviva Investors)
European limited partners (Plural, Aviva Investors)
Pan-European fund Plural led Orbital's $50m and Aviva Investors co-anchored the BBB's Lansdowne spinout fund (event ID:3505), demonstrating that Continental and UK institutional capital can fill the growth-stage tier independently, though neither has the scale to compete with US growth funds at the $100m+ band that successive ex-DeepMind rounds will eventually reach.
France (DSIT / GENCI / Institut Pasteur)
France (DSIT / GENCI / Institut Pasteur)
France signed the UK-France Strategic Biomedical Alliance on 29 May, contributing €330,000 a year to researcher mobility and linking GENCI national compute to Isambard-AI; the bilateral format suits Paris because it produces scientific access without requiring EU-framework ratification while the UK-EU science relationship remains unsettled.
US growth investors (NVentures, General Catalyst, Crosspoint Capital)

NVentures entering Orbital's cap table for the first time and General Catalyst following on in Geordie's Series A signals US growth investors treating London deeptech as a buy-side opportunity the UK market cannot contest. NVentures gains supply-chain visibility into GPU cooling; General Catalyst gains a frontier security category the RSAC prize has already validated for US enterprise.
UK Government (DSIT / British Business Bank)
UK Government (DSIT / British Business Bank)
The BBB cornerstoned Longwall at the seed floor on 27 May while DSIT signed the UK-France bilateral compute deal the same week, deploying state capital at bottom and research layers simultaneously. Neither instrument addresses the Series B middle the April 2026 mandate expansion could reach but has not.
Australian Department of Defence (AUKUS partner, Rowden Technologies)
Australian Department of Defence (AUKUS partner, Rowden Technologies)
Rowden Technologies holds active AUKUS AI for Acoustics contracts with the UK, US and Australian defence establishments. The NWF's £25m investment in Rowden on 13 May places UK sovereign capital directly into a trilateral programme Australia co-funds; from Canberra's perspective, the NWF cheque increases UK government skin-in-the-game on a programme where Australia has already committed co-development resources.
Temasek (Singapore sovereign co-investor, Isomorphic Series B)
Temasek (Singapore sovereign co-investor, Isomorphic Series B)
Temasek co-invested with the SAIU in Isomorphic's $2.1bn Series B the previous week, treating a majority Alphabet-owned company as a valid sovereign co-investment target. Fractile's round, without a UK sovereign co-investor, reads differently from Singapore's vantage: allied state capital (NATO-IF, In-Q-Tel) is now competing with Asian sovereign funds for early positions in UK deeptech.
