The volume of off-balance sheet liabilities of Alphabet, Microsoft, Amazon, Meta (recognized as extremist in the Russian Federation) and Oracle related to investments in AI infrastructure almost doubled in six months and reached $3.2 trillion, Nikkei Asia writes. About 60% of this amount comes from commitments to purchase equipment and energy, and 40% from leasing agreements. Alphabet has the largest amount of hidden debt - $1.05 trillion.
