Among the 50 London-based AI entries shown, the largest disclosed round is Isomorphic Labs at $2.1B on 2026-05-12, which dwarfs the next-largest disclosed amounts (Ineffable Intelligence at $1.1B on 2026-04-27 and Behavox at $173M on 2026-06-17). At the other end, the smallest disclosed amount is $120K for Pulse. on 2026-06-02, far below the mid-range of $10M–$30M rounds such as Adfin ($18M on 2026-05-12) and Ethos ($23M on 2026-05-06).
The rounds cluster tightly in mid-to-late 2026: the most recent entry is 1001 AI on 2026-06-30, while the oldest shown is 2026-04-23. Stage reporting is split—only some rows name a specific stage, and many disclose “Series Unknown” or “undisclosed” amounts (Mad Devs on 2026-06-29, Automata on 2026-06-25, and Youtility on 2026-04-23), adding uncertainty around how much capital actually changed hands across the calendar window.

Frequently asked
What stands out on deal size, and is it just one anomaly or a broader pattern?
Deal size is extremely top-heavy: Isomorphic Labs raised $2.1B on 2026-05-12, while Ineffable Intelligence ($1.1B on 2026-04-27) is the only other disclosed round above $1B; the next-largest disclosed amounts are far lower (Behavox at $173M on 2026-06-17 and PhysicsX at $300M on 2026-06-08). Smaller disclosed rounds cluster around the $1M–$25M band (e.g., Dayjob and Inth at $500K each on 2026-06-16; Archestra.AI at $10M on 2026-06-02).
How concentrated are these London AI rounds by time within the 50-row window?
The list compresses into a ~10-week span in 2026, from 2026-04-23 (Youtility, undisclosed) to 2026-06-30 (1001 AI, $30M). Multiple rounds land in late June—e.g., $34M (NexGen Cloud, 2026-06-25), $3M (Kalipso, 2026-06-25), and $30M (1001 AI, 2026-06-30)—suggesting a recent, time-local burst rather than evenly distributed announcements.
Which stage labels dominate, and how much of the list is missing structured stage or amount details?
Stage labels vary, but “Series Unknown” appears frequently alongside several entries with “undisclosed” amounts (e.g., Mad Devs on 2026-06-29 is Series Unknown and undisclosed; Automata on 2026-06-25 is Series C with undisclosed; Advancing Analytics on 2026-06-11 is Series Unknown with undisclosed). That combination means some calendar dates (like 2026-06-25 and 2026-06-09) reflect reporting gaps that can’t be compared on $ size.
Are there any clear size clusters around particular dollar ranges?
Beyond the top two outliers ($2.1B Isomorphic Labs on 2026-05-12 and $1.1B Ineffable Intelligence on 2026-04-27), many disclosed rounds concentrate in a mid band: several companies report $18M–$25M (Capsa AI $18M on 2026-06-09; Ethos $23M on 2026-05-06; Hypervision Surgical $23M on 2026-04-29; All3 $25M on 2026-04-29). Meanwhile, the low end includes very small disclosed checks such as Pulse. at $120K on 2026-06-02 and multiple $500K rounds (Dayjob and Inth on 2026-06-16; Tellis Labs at $500K on 2026-05-07).
Which entries are worth extra diligence because they combine large size with specific dates?
The most obvious diligence targets are the two largest disclosed rounds: Isomorphic Labs ($2.1B on 2026-05-12) and Ineffable Intelligence ($1.1B on 2026-04-27). Behavox ($173M on 2026-06-17) and PhysicsX ($300M on 2026-06-08) also sit far above the median-sized cluster, making them useful anchors when validating whether later quotes in the same window reflect true acceleration or just reporting concentration.
