Question 1

What is the brain economy?

Accepted Answer

The brain economy is the collection of industries whose value depends on understanding, augmenting, or replicating human cognition — neurotechnology, NeuroAI, brain health, cognitive enhancement, mental health tech, workforce productivity, and neuroeducation. In 2024 it represents roughly $1.9T in global economic activity and is projected to reach $3.8T by 2030.

Question 2

How big is the neurotechnology market in 2026?

Accepted Answer

The neurotechnology hardware market (BCIs, neurostimulation, neuroimaging) is approximately $19B in 2026, growing at 15.8% CAGR toward $38.4B by 2030. Brain-computer interfaces specifically account for $2.4B and are the fastest-growing sub-segment.

Question 3

What is driving NeuroAI investment?

Accepted Answer

NeuroAI attracted $14.2B in 2025 — nearly triple 2023 levels — driven by three converging trends: foundation-model architectures increasingly borrowing from neuroscience (predictive processing, sparse coding), neuromorphic chips reaching commercial viability, and enterprise demand for more sample-efficient, energy-efficient AI.

Question 4

Which brain-economy sector is growing fastest?

Accepted Answer

NeuroAI and brain-inspired AI lead at 31.7% CAGR, followed by cognitive enhancement (23.4%) and mental health tech (19.5%). Brain health & longevity is the largest by absolute size but grows more slowly at 8.0%.

Question 5

Who are the leading brain-economy companies?

Accepted Answer

Neuralink, Synchron, Precision Neuroscience, and Blackrock Neurotech lead BCIs. Numenta, Verses AI, and DeepMind lead NeuroAI research. Eli Lilly, Biogen, and Eisai lead brain-health therapeutics. Headspace Health, Spring Health, and Woebot lead mental health tech.
