Their collective share of global GDP could increase from4 percent to 10 to 16 percent by 2040. —Twelve arenas of today showed outsize growth and dynamism from 2005 to 2020.Theseindustries include e-commerce, biopharma, electric vehicles, consumer internet, and cloudservices. They had a revenue compound annual growth rate (CAGR) of 10 percent and marketcapitalization CAGR of 16 percent, and they tripled their global GDP share from 3 to 9 percent inthe period. By contrast, non-arenas had only a 4 percent revenue CAGR and a 6 percent marketcap CAGR over the same period. —The many striking differences between the 12 arenas of today and non-arenas inform ourunderstanding of the arenas of the future.Arenas earn far greater profits than other industriesdo, they spawn a disproportionate number of global giants, and they offer unusually strongopportunities for new entrants to become powerhouses. —Three combined ingredients in an “arena-creation potion” tend to generate the escalatorymode of competition that characterizes arenas.The telltale elements of a forming arenaare business model or technological step changes, escalatory investments, and a large and/orgrowing addressable market. The presence of these elements can lead to escalatory competitionamong players, who make large investments to gain not only market share but also a productquality edge, compounding the benefits and further sett
