Which sectors are attracting the most AI investment, and which are being overlooked?

The insurance sector is attracting significant AI investment, with two-thirds of the $5.08 billion in annual insurtech funding in 2025 directed toward AI-focused companies, marking it as the most substantial year for such investments in this area [2]. Broader AI investments are heavily concentrated in big tech and AI infrastructure, where companies like Amazon, Microsoft, and Meta are committing billions—totaling around $660 billion in 2026—to secure dominance, alongside massive funding for AI startups like Anthropic, OpenAI, and xAI, which captured 50% of VC funding in 2025 [5][6][8][9]. In contrast, the energy sector is being overlooked, as AI's capital pull has led to a decline in energy tech investments, potentially slowing innovation in sustainable solutions [7].
