What is the Pentagon Pizza Index?
The Pentagon Pizza Index: where the idea came from, what the pizza trackers measure, what they get wrong, and how SIREN applies the same idea to AI with public counts.
Where did the Pentagon Pizza Index come from?
The idea traces to Frank Meeks, a Domino's franchise owner in the Washington area. He told reporters that late-night orders from the Pentagon, the CIA and the White House jumped before major events. The best-known claim: on 1 August 1990 the CIA ordered a one-night record of 21 pizzas, and Iraq invaded Kuwait the next day. Meeks also described surges before the Grenada and Panama invasions and during the 1998 Clinton impeachment fight. (Wikipedia: Pentagon pizza theory; Modern Diplomacy)
How is it tracked today?
Since 2024, accounts such as the Pentagon Pizza Report on X and the PizzINT dashboard read Google Maps "popular times" data for pizza shops near the Pentagon. On 12 June 2025 at 6:59 pm ET the account posted that nearly all nearby pizza places showed a surge; Israel struck Iran about an hour later. (Washingtonian; USA Today via AOL)
Does it actually work?
Nobody has published a test of it. The famous cases are remembered because something followed; the busy nights with no event are not counted. Google's busyness figures are estimates from phone location data, a shop can be busy for ordinary reasons, and several outlets questioned the timeline the account gave for the June 2025 strikes. Treat it as a folk signal, not a measurement.
How does SIREN apply the same idea to AI?
SIREN borrows the format, a single public gauge built from things anyone can watch, and points it at AI instead of the Pentagon. The inputs are counts: papers on arXiv, model releases on Hugging Face, SEC filings, Federal Register rules and prediction-market prices. Every hourly reading is hash-chained, so anyone can re-check it. It measures how busy the AI world is, not what happens next. Side by side: SIREN vs PizzINT.

Quick answers
What is the Pentagon Pizza Index?
An informal idea that late-night pizza orders near the Pentagon jump before major military or political events. It started with stories from a Washington-area Domino's franchise owner, Frank Meeks, around 1990 and is now tracked with Google Maps busyness data.
Is the Pentagon Pizza Index accurate?
It has never been tested. The cases people cite are the ones where something followed; busy nights with no event go uncounted, and Google's busyness data is an estimate.
Sourced facts checked 2026-11-14. SIREN measures how much is happening, not how bad it is. Levels run from 5 (quietest) to 1 (loudest) and describe observable activity tempo against this index’s own record. They are not a probability of harm.
