Al Jazeera English reports that the US company Palantir is using data generated by Ukraine's war to train its technologies. The outlet characterises the data as unique to Ukraine's wartime experience and the technologies as controversial. In its headline, it asks whether Ukraine is paying a heavy human price, framed as paying with blood, for Palantir's access to battlefield intelligence. The outlet poses this as a question, not a finding. This brief draws on the outlet's headline and standfirst only. Details of what data Palantir uses, how it obtains it, any agreement with Ukraine's government or military, and why the technologies are called controversial are not available. No response from Palantir or Ukrainian officials is available.
