UK public sector AI procurement has hit a record £1.41 billion so far in 2026, according to new figures that show Microsoft, Palantir and other major suppliers still dominate the government technology market. Public bodies awarded 453 AI-related contracts worth £1.41 billion between the start of 2026 and 3 August, according to the Tussell AI Procurement Tracker - already surpassing the £1.18 billion awarded across 521 contracts in the whole of 2025.
Since January 2018, Tussell has identified 2,129 AI-related public sector contracts worth a combined £5 billion. But much of that value has gone to large, established suppliers, while UK start-ups warn they are losing faith in government as a buyer and technology champion.
AI contract value accelerates sharply
Tussell recorded £424 million of AI-related public contracts in 2023, rising to £582 million in 2024 and £1.18 billion in 2025. With more than a quarter of 2026 still to go, this year's total is already the highest on record, and the number of contracts is on course to surpass last year's 521.
The tracker cautioned against overstating the scale of this activity. The £5 billion of AI-related contracts identified since 2018 represents roughly four percent of the £123 billion of IT services and software contracts awarded by the public sector over the same period.
Historic figures have also been skewed by particularly large awards. The spike to £1.15 billion in 2021 was largely driven by a single £1 billion Met Office supercomputing contract awarded to Microsoft.
Established suppliers capture most spend
Microsoft is the largest supplier identified by Tussell since 2018, with £1.03 billion of AI-related contract value. Palantir follows with £628 million, while KPMG has secured £320 million.
Other leading suppliers include Hochtief at £300 million, Laboratory of the Government Chemist at £284 million, Init at £259 million and IBM at £247 million. Hewlett Packard Enterprise, EY and FutureLearn complete the top ten.
UK-based suppliers have won just under £2.19 billion of AI-related contracts since 2018, compared with £2.28 billion awarded to US-based firms. That gap has narrowed considerably from June, when US suppliers were ahead by almost £1 billion. By August, their lead had fallen to just over £80 million, helped in part by a £456 million Cabinet Office contract awarded to KPMG and EY for a new National School of Government and Public Service covering civil service training in digital and AI.

Start-ups struggle to break in
Tussell found that just over a third of AI contracts identified since January 2018 were awarded through frameworks. Across the wider public sector, roughly one in four contracts is awarded this way.
Start-ups argue frameworks create particular problems for younger companies. They reopen only periodically, while bidding requirements and approval processes can raise barriers to entry.
The Startup Coalition told The Times that start-ups faced risk aversion, procurement delays and difficulties accessing government buyers. It warned that government commitments to back domestic tech companies would need accompanying changes to how the public sector buys.
"For British start-ups and scale-ups, this really is the last-chance saloon after successive administrations have delivered warm words but little real action. The result is an ecosystem increasingly losing faith in the UK government as a buyer and champion," said the coalition.

What the contracts cover
Tussell identified AI contracts covering compute and infrastructure, AI adoption and deployment, data management, governance, skills and workforce development and public trust.
Examples include NHS England's £182 million Federated Data Platform contract with Palantir, a £13.5 million Department for Work and Pensions contract with IBM for GenAI Lighthouse Projects, and a £7.4 million Ministry of Defence contract with Kainos to develop AI skills.
Why this matters for government professionals
The record procurement total signals that AI-related work is becoming a routine part of public sector delivery, not a passing experiment.
That carries practical implications for procurement officers, digital leads and. Frameworks and supplier structures favour incumbents, meaning teams navigating these contracts need specific knowledge of how AI procurement differs from traditional IT buying. Tussell's data also suggests the gap between established suppliers and newer entrants is narrowing - which shifts the competitive position of public sector contracts in ways that procurement professionals will need to factor into their decisions.
Understanding who is winning this spending and under what contract structures offers a useful benchmark for teams planning their own AI acquisitions for the year ahead.
