The dominance of artificial intelligence (AI) investments in venture capital (VC) has been a consistent storyline in the first half of 2025. PitchBook, Carta, Crunchbase, and many others have all pointed to the significant portion of investment dollars and deals flowing to AI companies. With the volume of companies, deals, and dollars involved, it is more than a spike in the usual cyclic nature of VC investment.
As SSTI wrote in our review of Q1 venture capital investment activity, VC has been concentrating in larger deals. With market trends and mega deals in AI so well documented, we explore investment concentration from deal size and geographic perspectives. As with prior analyses, we focus on deal sizes more relevant to TBED initiatives to help regional innovation leaders identify where they might find opportunities, face challenges, or set priorities in such a dynamic environment. Excluding the largest deals from our analysis appears to be increasing important, considering PitchBook’s findings that just ten companies accounted for 41% of all venture dollars so far this year.
