Methodology and sourcing behind the figures and links shown above.

LLM observability

LLM-specific market reports estimate a small but fast-growing segment: Business Research Company projects ~USD 1.97B in 2025 and a ~36% CAGR to 2030. Independent posts and vendor/industry reports (LinkedIn summary, Next Move, MarketsandMarkets) show similar high-growth LLM/AI-observability tails (~31–36% for AI/LLM observability) while broader observability markets are larger but slower-growing, indicating LLM observability is a high-growth subset.

AI cost and infrastructure optimization

Estimate anchored to published IT cost-optimization market sizing (USD 1.68B in 2025) as the closest available segment baseline, adjusted upward to reflect AI-specific demand and larger AI infrastructure budgets (AI infrastructure/compute ~USD 110B in 2025) and faster growth in AI infrastructure. Data‑center infrastructure sizing and growth rates (U.S. data center infra ~USD 49.6B in 2025; ~12% CAGR) provide a broader infrastructure context. Combining the niche baseline with higher AI infrastructure growth supports an estimated ~USD 2.0B market with ~20% CAGR for AI cost & infrastructure optimization solutions.

Model traffic management

No explicit market-size data for “model traffic management” (AI proxy/gateway) was found in the provided search results. I used the provided traffic/transportation traffic-management market reports as adjacent market benchmarks (Coherent Market Insights, Polaris, Grand View Research) and applied domain knowledge about AI infrastructure and model‑serving niches to estimate a much smaller, high‑growth submarket. Rationale: major traffic-management reports show global markets in the tens of billions with ~8–14% CAGRs; model traffic management is an adjacent software/infrastructure niche (gateways, routing, semantic caching, failover for model inference) and likely represents a small fraction of AI infrastructure spend today (~$0.5–1.0B), but with faster adoption as multi‑provider inference and reliability tooling scale — hence the estimate of $0.8B and ~30% CAGR.

On-premises and sovereign AI infrastructure

Search results show strong demand signals for on‑premises and sovereign AI (repatriation trends, rising public‑cloud AI costs, vendor roadmaps to run frontier models on‑prem) but contain no explicit market sizing. Using those signals plus industry hierarchy: global AI infrastructure (servers/GPUs, private cloud, software, integration/services) is large; assume on‑prem/sovereign deployments represent roughly 10–15% of total AI infrastructure spend today. Applying that to a conservative total AI infrastructure market estimate produces a market size of about $20–30B (midpoint $25B). Given regulatory pressure, cost repatriation drivers, and vendors investing in on‑prem stacks, estimate a high growth profile — roughly 20–30% CAGR — midpoint 25% over the next 3–5 years.
