*2026 is partial. Company themes use the tags available in this dataset, applied to historical rounds; they do not date when a business adopted a technology. Themes overlap, so shares do not add to 100%. Each company round is counted once within a theme. These charts cover investors from all locations; the shortlist keeps its own location filter.
How a spike is detected
A complete quarter is flagged when its theme share is at least 1.75× the share across the preceding four quarters and at least 5 percentage points higher. It must contain at least 3 theme rounds across 3 companies, at least 10 market rounds, and at least 3 theme rounds in the baseline. All four baseline quarters must have market observations. A zero baseline, missing observations or partial quarter cannot produce a flag.
This is a transparent screening rule, not a statistical significance test or a forecast. A higher share can accompany fewer rounds when the wider market contracts; the counts beside the chart make that distinction visible.

07 / READING THE ATLAS
What these patterns can tell you.
The market boundary
Recorded equity rounds for companies tagged AI Infrastructure and located in London. Investor headquarters may be elsewhere. Company sector and location reflect the available company records, not necessarily the location or sector at the investment date.
The time boundary
Data coverage ends 22 May 2026. The latest market round is 19 May 2026. There are 3 undated participations, excluded from timing metrics. Activity after the cutoff is unknown.
The relationship boundary
“New” is the first dated relationship between a backer and a company in this market. “Backed again” requires a later dated round together. A first observed entry may follow an earlier unrecorded investment.
The financing boundary
Amounts describe entire equity rounds, not personal cheques, fund capacity or returns. Medians exclude missing and non-positive amounts; the middle half spans the 25th–75th percentiles. A recorded investment does not establish current availability.
