Index funds buy companies, for the most part, according to their market capitalisation.
They own more of bigger companies than small.
There's the option of "equal weight" or other strategies but the overwhelming majority is market cap weighted.
Index funds are also really, really big now and contain a lot of money earmarked for retirement/pensions.
In theory if you had a temporarily very frothy market into which you could sell a part of your unprofitable company to some people at a very high valuation, index funds would then mechanically move in and need to purchase and add significant support for insiders to sell into.
