The Signal Index · Updated 2026

Predicting tomorrow's tech
with today's leading signals

A quantitative trend index tracking 14 leading indicators across 240 cities to forecast which technologies, places, and sectors will dominate the next 24 months. We don't guess — we measure.

01 Top trend themes for 2026

Each theme is scored 0–100 from a weighted blend of VC inflows, patent velocity, GitHub stars, job postings, and academic publications. Above 80 = high-conviction signal.

02 The funding pulse

Global venture capital deployed into emerging tech, by year. The 2024 trough is over — 2026 is on pace to match the 2021 peak, but with very different category leaders.

Key insight: The 2021 wave was led by consumer crypto + late-stage SaaS. The 2026 wave is led by AI infrastructure (38%), industrial climate (19%), and humanoid robotics (14%). Same dollar volume, completely different shape.

03 Where to look next

Local

Austin

Score 94/100. AI infra + semiconductors + climate convergence. East Austin garages are the new Mountain View.

Austin deep dive →
Regional

Texas

Six metros tracked. Austin leads, but Houston's energy-tech rebound and DFW's defense AI cluster are the dark horses.

Texas rankings →
National

US Tech Centers

12 metros ranked. SF Bay still #1 but its lead is narrowing. Austin closed the gap by 17 points in three years.

US rankings →
Global

World cities

24 cities across 6 continents. Asia now hosts 4 of the top 10. Africa's Lagos broke into the top 25 for the first time.
