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, representing the most substantial year for such investments in this industry [2]. Broader AI investments are heavily concentrated in big tech infrastructure, startups like Anthropic, OpenAI, and xAI (which raised double-digit billions and accounted for 50% of VC funding in 2025), and general AI research and development, totaling billions from major players despite bubble concerns [5][6][9]. The US dominates globally with $67.22 billion in private AI investment in 2023, followed by China's rapid growth [3]. Conversely, the energy sector appears to be overlooked, as AI investments are diverting capital away from energy startups, leading to a decline in energy tech funding and potentially hindering innovation in sustainable energy solutions [7].
