- Average deal size triples year-on-year to $1.5 billion as investors shift focus to later-stage companies
- US accounts for 97% of global deal value and 62% of volume, EMEA accounts for 23% of volume but just 2% of deal value
- Of 39 global AI Unicorns 29 are based in the US, just 3 in Europe
- Substantial opportunity for Irish startups as GenAI adoption soars, however bridging funding gap remains challenging
Dublin, 5th August: Global venture capital (VC) investment in generative artificial intelligence (GenAI) surged to $49.2 billion in the first half of 2025, outpacing the total for all of 2024 ($44.2 billion) and more than double the total for 2023 ($21.3b), according to EY Ireland’s latest Generative AI Key Deals and Market Insights study.
The sharp rise in overall deal value comes despite a near 25% drop in the number of transactions for the first six months of 2025 versus the second half of 2024, as VC firms concentrate on more mature, revenue-generating AI companies, resulting in fewer but significantly larger deals. Average transaction size for late-stage deals more than tripled to more than $1.55 billion, up from $481 million in 2024, while early-stage VC rounds declined, and angel and seed rounds saw no change.
A wave of high-value investment into some of the most established players has underpinned this record first half of the year, including SoftBank’s commitment to OpenAI which could reach $40 billion, xAI’s $10 billion funding round, and major investments in Databricks ($5 billion), Anthropic ($3.5 billion), Mistral AI ($600 million), and Harvey ($600 million). Additionally, Agentic AI – which enables systems to perceive, decide and act autonomously – has emerged as a key growth area. Capgemini’s $3.3 billion acquisition of WNS and Berlin-based Parloa’s $120 million raise, propelling it to a $1 billion valuation, are among the notable deals in this area. While not covered in the data for the first half of the year, the recent acquisition of Irish predictive media analytics firm NewsWhip by Sprout Social is a welcome boost to the local sector.
Commenting on the findings Grit Young, EY Ireland Techology, Media and Telecoms Lead said:
“GenAI continues to reshape the investment landscape at an extraordinary pace. The first half of 2025 has already surpassed last year, which was also a high-water mark. That momentum is expected to continue and build further into the second half of the year with the launch of new GenAI platforms and their faster revenue generation capabilities.
“While there was substantial concern at the start of the year with the launch of DeepSeek that investment in GenAI was likely to trend downwards, the results for the first half of the year point to a very different scenario. We are seeing a clear pivot to less but more substantial investments, which are pointed towards more mature companies and platforms that can demonstrate they can deliver real-world impact and return on investment. This growth being fuelled by rising adoption across industries, high demand for sector-specific solutions and continued innovation in AI hardware, particularly semiconductors.
GenAI is entering a new phase, and the scale of investment reflects growing confidence in its commercial potential. The recent results from the ‘Magnificent Seven’ underscore how rapidly this technology is being adopted by customers, and we would expect that the investment trajectory is likely to accelerate through the second half of the year and beyond.”
It would appear that GenAI has skipped through the traditional ‘trough of disillusionment’ for new technology adoption quite quickly and has now moved into another upswing cycle."
