    Some argue that large platforms, such as Alphabet/Google, Amazon, Apple, Facebook and Microsoft (or GAFAM), are unusual in their number, pace and concentration of technology mergers, with the potential to harm market competition. Using a unique taxonomy developed by S&P Global Market Intelligence, we compare the M&A activities of GAFAM to other top acquirers from 2010 to 2020. We find: (i) GAFAM completed more tech acquisitions per firm than other groups of top acquirers, and acquired younger and more consumer-facing firms on average. (ii) The top 25 private equity firms outpaced GAFAM in tech acquisitions per firm since 2018. (iii) GAFAM acquisitions are less concentrated across tech categories than other top acquirer groups, due, in part, to an "acquire-adjacent-and-then-expand" strategy. (iv) Over time, more and more GAFAM and other top acquirers acquire in the same categories. (v) No evidence suggesting that a GAFAM acquisition in a category, compared to similar categories without GAFAM acquisitions, is correlated with a slowdown in the number of new acquirers acquiring in that category. Overall, we find that technology acquisitions do not shield GAFAM from competition, at least not from other GAFAM members or other firms that acquire in the same categories
