Why America’s big companies keep getting bigger




The irony of the Silicon Valley Bank saga is now complete. The crisis started inside the American tech sector’s favourite bank, but the government rescue has benefited Big Tech the most. As calm returns to the market, fuelled by megacap tech stocks, investors are naturally relieved. They need to be aware, however, of where a system built on bailouts is heading.

Even two decades ago, capitalism was marked by boom-bust cycles that disrupted incumbents and created space for upstarts. While still a ubiquitous word, “disruption” is finally fading as churn in the market stalls. The big beneficiaries of post-crisis rescues are big, established companies — and this is not how capitalism is supposed to work.

After the government stepped in on March 10 to rescue SVB, megacap stocks had one of their best runs ever. Today, all of the top five US companies are tech businesses and together they represent more than 20 per cent of the stock market — the highest concentration since the 1960s and more than double the figure a decade ago.

The decline in competitive churn is a side-effect of the rescue culture that has been growing since the 1980s. Ever since the US Federal Reserve stepped in to prop up the market after the 1987 crash, the stock market has grown dramatically, from half the size of the US economy to two times larger at its peak in 2020. One might assume an expanding market should create room for more churn, but no, not in America.

The number of US companies that remain in the top 10 from one decade to the next has risen steadily, from just three in 1990 to six at the end of the 2010s. And while churn has weakened in the US, it remains relatively robust across much of the world. From the start to the end of the 2010s, just two companies remained on the top 10 list in Japan, four in Europe, four in China and two in the global list, Microsoft and Alphabet.

Today, the top five US companies are bigger than the next five by the largest margin since the early 1980s. The top two alone account for nearly half the market cap of the top 10, up from 35 per cent at the start of the pandemic. Apple is now number one, and is nearly six-times larger than UnitedHealth Group, in 10th place. Three decades ago, Exxon was number one but just over twice the size of the tenth company, BellSouth.

Competing explanations for the rise of Big Tech include the natural advantage of size on digital networks, where companies can add customers at negligible added cost. But “network effects” can’t explain why three out of every four US industries — and not just in the tech industry — have been consolidating in the hands of a few companies. Sweeping government rescues that benefit incumbents can.
