HSBC chief multi-asset strategist Max Kettner said a "melt-up" in tech stocks is currently boosting the hyperscaler sector.

This shift indicates a reversal in investor sentiment toward the largest cloud computing providers. As these companies demonstrate an ability to maintain high profits while investing heavily in new technology, they are regaining favor with shareholders who previously avoided them.

Speaking on Bloomberg Television's "Surveillance" program, Kettner said that the acceleration of AI spending is the primary catalyst for this trend. He said the market is witnessing a surge in valuation as the scale of artificial intelligence integration becomes clearer.

Kettner highlighted a specific tension between massive capital expenditure and earnings. He said investors who recently scorned so-called hyperscalers are starting to come back as the companies show they can mint profits while spending hundreds of billions of dollars [1] on artificial-intelligence infrastructure.

This trend reflects a broader market appetite for companies that can scale AI operations without eroding their bottom line. Kettner said, "We are seeing a melt-up in the hyperscaler space as AI spending accelerates."

The strategist's assessment suggests that the sheer volume of investment—reaching hundreds of billions of dollars [1]—is being viewed by the market as a long-term competitive advantage rather than a financial liability. This perspective supports the continued dominance of a few massive players who possess the capital necessary to build the physical infrastructure required for next-generation AI.

The return of investor confidence in hyperscalers suggests that the market has moved past concerns regarding the high cost of AI implementation. By proving that massive infrastructure spending can coexist with strong profitability, these companies are validating the 'arms race' approach to AI development, potentially widening the gap between them and smaller competitors who cannot afford similar capital outlays.
