Aerospace AI: The Temptation to Extrapolate an Early Growth Rate Over Eight Years

According to a report published by SkyQuest Technology Consulting, the global aerospace artificial intelligence market grows from $2.29 billion in 2024 to $3.28 billion in 2025, a 43.2% increase in one year. The report then extends this trajectory across 2026-2033 with a stated compound annual growth rate (CAGR) of 43.1%, reaching $57.61 billion by 2033 — a roughly 25x increase in nine years.

The drivers behind this growth are documented and plausible at the sector level: predictive maintenance from sensors embedded in engines, wings and avionics; the exploding volume of data generated by modern aircraft systems; and rising demand for autonomous aircraft, military drones and UAVs, driven by both defense needs and commercial aviation. Software currently dominates the offering (data analytics, predictive-maintenance algorithms), with hardware — sensors, embedded computers — flagged as the fastest-growing segment. North America remains the dominant region by value, Asia-Pacific the fastest-growing by pace.

The point worth an economic examination isn't the plausibility of the cited drivers, but the projection method itself. A CAGR is, by construction, a geometric average: it implicitly assumes that the pace observed over an initial period repeats identically over the entire projection horizon. Yet the first observed year here — 2024 to 2025 — starts from a base of just $2.29 billion, a tiny fraction of the global aerospace industry, which alone generates several hundred billion dollars in annual revenue. On such a narrow base, a limited number of new contracts or deployments is enough to produce a spectacular growth percentage, without that revealing a diffusion pace sustainable at scale.

This conflation of seeding-phase pace with structural pace echoes what Tversky and Kahneman called the law of small numbers (1971): statistical intuition tends to extrapolate from overly small samples, overestimating the reliability of trends calculated from few observations. Applied to market forecasting, this psychological bias has a well-documented economic analogue: technology diffusion models (Bass, 1969; Rogers, 1962) show that adoption of a new technology typically follows an S-curve — slow growth at launch, rapid acceleration in the middle phase, then mechanical deceleration as the addressable market saturates. A 43% CAGR calculated over an S-curve's first two years measures the slope of the acceleration phase, not the more moderate one that will inevitably follow during maturation.

The order-of-magnitude gap with adjacent markets illustrates the issue: the AI beauty and cosmetics market, analyzed by Cardan-AI last week, shows a CAGR of 19.6% to 21.1% on a starting base ten times larger ($4.38B) — and its growth rate is already declining year over year. Nothing suggests the aerospace AI market will escape that same convergence dynamic once its base widens; the history of technology diffusion suggests the opposite.

For aerospace and defense executives building investment plans or due diligence on this kind of figure, the operational lesson is simple: an eight-year CAGR extrapolated from a two-year base should be treated as a trajectory hypothesis, not an established fact. The scrutiny belongs less on the endpoint ($57.61B by 2033) than on the robustness of the constant-pace assumption required to reach it — an assumption that technology diffusion theory gives good reason to doubt.
