Is Big Tech Creating a National Security Crisis? Pentagon Says U.S. Troops Were Targeted Using Ad Data

The Pentagon warned that commercially available location and ad-data can be purchased by hostile actors to target U.S. troops, shifting the ad-tech debate from consumer privacy to national security. That raises the likelihood of faster, bipartisan regulation that could erode targeting precision, increase compliance costs and compress margins for ad-driven tech companies. Alphabet and Meta — which together generate the bulk of digital ad profits — remain well-positioned due to scale and large free cash flow, but smaller ad-tech firms and data brokers face greater regulatory and cost pressure. Investors should expect risk to the advertising margin rather than an outright collapse of the ad model, and to favor large platforms capable of absorbing higher compliance costs.
