Money is entering at multiple layers at once: venture rounds (Simplismart at $40-50 million; Tether's $15 million for Mural), a projected IPO pipeline (India's USD 100 billion, per Goldman Sachs), and incumbents building payment rails for agentic AI (Visa, Mastercard), which may indicate the AI agent economy is becoming an investable theme in itself. Risk appears to be concentrating in operations and cyber: IwaiCosmo's initial claim of an AI-driven brute-force attack — later retracted — and IBC's warning on AI and shared technology point to AI as both tool and attack surface. Regulators seem to be moving from principles to mechanics — stress testing at the Bank of England, sound practices at OSFI, and mandatory disclosure floated at the FCA — suggesting oversight is likely to center on operational resilience and transparency. Breakingviews' framing of NVIDIA as the AI industry's central bank highlights concentration risk: stress at a single anchoring supplier may transmit across the ecosystem.
