We're watching the biggest infrastructure wave in modern U.S. history unfold right now.

AI and data center buildout is projected to hit 3.63% of GDP annually from 2025-2032. That's bigger than railroads in the 1870s (2.24% of GDP), highways in the 1950s-70s (1.13%), the telecom boom in the late 90s (1.10%), and way beyond electrification in the early 1900s (0.50%).

Total spend: ~$10.3 trillion over eight years.

This isn't just hype. It's real capital flowing into physical infrastructure—land, power, chips, cooling systems, fiber. Companies like $NVDA, $MSFT, $GOOGL, $META, $AMZN are all racing to build capacity.

For context, the last time we saw infrastructure investment reshape the economy at this scale, it was literally the railroads connecting the continent.

The market is pricing in AI as a long-term structural shift, not a short-term theme. Whether that pays off depends on monetization, but the capex commitment is already historic.
