More than 1 in 20 of all research moves within the United States for the period 2020-24 were from academia to companies, according to data from Sydney-based analytics company League of Scholars. Moves were calculated based on verified Google Scholar accounts affiliated with company e-mail domains, which means moves in countries where Google Scholar use is relatively low among corporate researchers, such as China, might be underrepresented. US companies lead as top destinations for academics moving to corporate research roles, based on 68,210 verified global cross-sector movements for 2020-24. Nearly 4% of these transitions were to Amazon and Google, with just over 2.5% specifically to Amazon.
