However, Alphabet’s growth is larger than IBM’s, and in fact, there may be trouble ahead for Big Blue.For the second quarter, IBM’s $17.2 billion in revenue was just a 1% increase over the prior year despite operating in the hot artificial intelligence sector. Moreover, Big Blue cut its 2026 full-year guidance from more than 5% year-over-year growth to between 4% and 5%. The slowdown is due to a sales decline in its consulting and hardware businesses.Alphabet is seeing an acceleration in its revenue growth. Its Q2 sales of $119.8 billion represented a 24% increase over 2025, up from Q1’s year-over-year growth of 22%. This is due to the company’s success with its AI efforts.In Q2, its Google Cloud business experienced 82% year-over-year growth to $24.8 billion, and this division’s backlog of customer orders rose to over half a trillion dollars compared to $462 billion in Q1.
