📊 Market Analysis — Where the Money Flows
Capital this week focused on AI infrastructure (chips, deployment) and defense/aviation AI. As seen with Fireworks AI and Tenstorrent, the valuation ceiling for software stacks has broken, and hardware/infrastructure startups have emerged as the core pillars of the market.
Geographically, US-based startups remain dominant, but M&A related to data infrastructure—such as Boomi's acquisition of an Israeli startup—shows signs of expanding into Europe and the Middle East.
On the investment stage side, while early-stage unicorns (Town) are emerging, growth-stage companies like Fireworks AI are demanding tens of billions in valuation, widening the polarization.
