AI infrastructure and chips ETFs, the companies their ten largest holdings name. The 15 most widely held of 45. Each fund files its whole book and this counts the ten largest out of it, so a fund missing from a row may still hold that company below its own tenth position. Weights are of the funds that name it, never of the theme. Source: each fund's latest SEC filing or its issuer’s own daily holdings file, read by ETFIQ.

AI infrastructure ETFs, the share of each pair’s weight held in the same companies. Read across or down; the figure is the same either way. Cells are shaded against the closest pair here, 48%. Weight overlap is the sum, over every company both funds hold, of the smaller of the two weights. Funds whose published book is cut short are left out rather than compared short, which would read as two funds being more different than they are. Source: each fund’s own filed or daily holdings, read by ETFIQ.
