CuspAI, a 2024 Cambridge AI-materials company, has signed term sheets for a reported $400m round at a $2.6bn valuation with Bezos Expeditions among the backers. The round is not yet closed.

Key takeaway

The fortnight's biggest UK round is foreign-led and not yet closed.

CuspAI, a Cambridge AI-materials company founded in 2024, is raising a reported $400m at a $2.6bn valuation, with Bezos Expeditions and Kleiner Perkins among the backers, according to the Financial Times 1. Term sheets are signed; the round is still being raised and has not closed 2. If it completes, the valuation lands at more than four times the company's September 2025 mark. Geoffrey Hinton and Yann LeCun, two of the people who built modern deep learning, sit on its advisory board.

The company solves a narrow problem. A customer specifies the properties it needs, a heat-resistant coating, a catalyst, a filter, and the platform generates candidate molecular structures and simulates them in silico before anyone touches a lab bench, compressing a discovery cycle that historically ran for years of wet-lab iteration. Meta is a customer for carbon-capture materials, Hyundai is another, and CuspAI worked with the Finnish chemicals group Kemira on materials to strip PFAS (per- and polyfluoroalkyl substances, the so-called forever chemicals) from water 3.

PhysicsX took its $300m Series C from Singapore's Temasek , and Orbital Industries closed an earlier Series B with no UK lead investor at all , the same shape the CuspAI round now repeats. British seed money is being rebuilt at the bottom of the market while the largest rounds are underwritten from Seattle and Singapore, which in practice means the founders stay in Cambridge while the upside accrues to investors abroad. AI-materials is the newest vertical to mint a near-unicorn this way, and it did so without a domestic lead.

Deep Analysis

In plain English

When a scientist or engineer needs a new material with specific properties ; say, a coating that resists extreme heat, or a filter that removes toxic chemicals from water ; the traditional approach is to mix and test compounds in a laboratory over months or years. CuspAI, a Cambridge startup founded in 2024, uses AI to do that work computationally: the computer generates and tests thousands of candidate molecules before anyone touches a lab bench. On or around 20 June 2026, the Financial Times reported that CuspAI is raising $400m from investors including Jeff Bezos's personal investment fund and the Silicon Valley firm Kleiner Perkins, at a reported valuation of $2.6bn. Term sheets have been signed, but the deal has not yet formally closed, so these figures are not confirmed. If the round does close at that valuation, it would make CuspAI worth more than four times what investors valued it at in September 2025. PFAS ; per- and polyfluoroalkyl substances, sometimes called 'forever chemicals' ; are a class of industrial compounds that persist in the environment and have been linked to health problems. CuspAI is working with the Finnish chemicals company Kemira to find materials that can remove PFAS from water, which is one reason industrial customers are interested even at this early stage.

Deep Analysis
Root Causes

AI-materials discovery requires a specific combination of frontier compute (for running molecular simulations at scale), large curated materials datasets, and the ability to hire researchers at the intersection of computational chemistry and machine learning.

UK universities produce the researchers; the compute and dataset infrastructure is concentrated in the US. Kleiner Perkins and Bezos Expeditions have direct relationships with the hyperscaler infrastructure that makes the product work, making them strategically useful LPs beyond the capital itself.

The valuation step-up mechanism ; more than four times the September 2025 mark ; reflects a commercial pull from industrial customers that was not visible at the earlier round. Meta's carbon-capture materials work, Hyundai's materials R&D, and Kemira's PFAS-removal brief are enterprise contracts large enough to reset the growth-capital case, and US growth investors are faster at repricing when enterprise traction signals product-market fit.

What could happen next?
  • Consequence

    A successful CuspAI close at $2.6bn resets UK AI-materials valuation benchmarks and is likely to attract further foreign capital into Cambridge's materials-science cluster within six to twelve months.

    Short term · Reported
  • Risk

    The round remains open and unconfirmed; a failure to close at the reported valuation, or at all, would damage the materials-AI narrative and may chill the wider UK deeptech valuation environment given how closely this round has been covered.

    Immediate · Reported
  • Opportunity

    PFAS-removal materials face a compliance-driven commercial demand curve from EU Water Framework Directive enforcement beginning in 2025–26; CuspAI's Kemira work positions it ahead of several years of regulation-mandated purchasing.

Different Perspectives
Fubon Financial
Fubon Financial
Fubon Financial joined Humanoid's Series A on 21 July as a minority financial investor alongside Schaeffler and Bosch, who also hold the customer and manufacturer roles. A pure-play investor from Taipei is pricing a London robot maker on terms two German industrial groups effectively set.
NATO Innovation Fund
NATO Innovation Fund
The Fund joined Greenjets' £30m Series A on 21 July alongside NSSIF, betting on ducted electric propulsion's civil market to fund a technology with an obvious defence application. It is backing a company that took twenty-one years to reach this stage, on the expectation that certification-cycle timelines reward patient capital over a quick return.
Prime Movers Lab
Prime Movers Lab
Prime Movers Lab led Humanoid's Series A on 21 July as the round's only pure financial investor, sharing the cap table with two co-investors who are also the anchor customer and the factory. That leaves the fund's usual arm's-length pricing role diluted by partners with a direct commercial stake in the valuation holding up.
Bosch and Schaeffler
Bosch and Schaeffler
Schaeffler signed what Humanoid calls the industry's largest publicly announced commercial agreement, while Bosch took equity and became contract manufacturer, filling capacity a shrinking combustion supply chain freed. Neither company has disclosed a unit count or an invoice, so their public commitment stops well short of Forbes' 100,000-unit projection.
UK founders raising seed through Series A
UK founders raising seed through Series A
A London robotics founder raised $152m this week against a signed industrial customer and a reserved factory, while a Cornwall founder more typically draws a £25,000 loan from a regional fund manager. Both call it British venture funding, but one route runs through Bosch's production line and the other through diligence built for businesses too small for any VC's attention.
EQT
EQT
EQT was reported on 3 July to be in advanced talks for a further CuspAI stake on behalf of the EU's Scaleup Europe Fund, but does not appear on the round CuspAI closed. Whether Europe's own sovereign vehicle secured a position, was outbid, or withdrew is unresolved.
