Intel has increased its planned stock offering to $20 billion from $15 billion, seeking additional capital as booming artificial intelligence demand pushes the chipmaker to increase spending on manufacturing capacity. Intel initially announced a $15 billion offering Monday before increasing its size by $5 billion early Tuesday. Intel is spending heavily to increase production capacity amid rising demand for processors and other infrastructure used in AI data centers. The $20 billion offering was priced at a roughly 1.3% discount to Intel's Monday closing price of $96.25, Reuters reported. The new stock sale gives Intel nearly $20 billion in additional cash to help fund that expansion.
