ASI raises $325M at $3B valuation to run AI for air traffic and grids

ASI, the AI company formerly known as Air Space Intelligence, has raised $325 million in a Series C round at a $3 billion valuation. Spark Capital led the round, with Citadel Securities, Andreessen Horowitz and Energy Impact Partners among the investors. The company builds models of air traffic and power grids that help operators plan ahead.

The customer list is the interesting part. ASI signed an $875 million, 12-year agreement with the FAA in June to manage future U.S. air traffic, beating bids from Palantir and Thales, according to Bloomberg. The FAA has already put the software into service at Dulles International Airport in Washington, with wider rollout planned. ASI also announced a five-year, $99 million deal with the U.S. Army for command-and-control software, and National Grid uses its tools for grid planning.

The catch is that the story is mostly about money and contracts, not measured outcomes. The company says its system reduces delays and improves safety, but no figures on delay reductions or grid savings have been published yet. Contract values are not the same as results.

For operators in aviation, defense and energy, the signal is clear: investors now pay real money for AI that runs physical infrastructure, not just text. Whether ASI names more public customers in the coming weeks will show how fast that market is actually moving.
