AI Funding Wave Rolls On: Security, Cloud and Infra Startups Score Fresh Capital

Funding trackers focused on artificial‑intelligence startups show no sign that the capital wave is slowing as of October 29, 2026. Recent data highlights several sizable rounds across different parts of the AI stack. In Canada, Solink raised more than $100 million to expand its platform, which uses AI to analyze footage from existing security cameras and surface fraud risks or operational insights for retailers and other businesses. Separate reports point to a soaring valuation for Fluidstack, a so‑called “neocloud” provider that rents out high‑end AI chips and infrastructure; investors are said to be considering a new deal valuing the company around $40 billion, more than double levels seen just weeks earlier. Aggregate statistics from multiple trackers suggest that AI startups worldwide have pulled in many tens of billions of dollars in October alone, spanning infrastructure, manufacturing, fintech and more. Still, analysts caution that rapidly rising valuations and heavy GPU‑related costs raise questions about how many of these companies can turn AI enthusiasm into durable profits. The market is gradually shifting from rewarding sheer AI buzz to scrutinizing whether individual use cases can scale economically.
