The hyperscale cloud providers, once considered laggards in the tech sector, are now taking the lead. With AI capital expenditures continuing to surge and free cash flow under pressure, a combination of accelerated cloud monetization, surging order backlogs, significantly compressed valuations, and a complete cleaning out of hedge fund positions is creating a convergence of factors. The market is now actively debating whether a second wave of the tech rally has already begun.
Over the past month, the MAGS index has notably outperformed both the Nasdaq 100 (NDX) and the Philadelphia Semiconductor Index (SOX), signaling a substantive shift in the relative strength of hyperscale cloud providers.
Simultaneously, over the previous few weeks, hedge funds heavily reduced their exposure to the "Mag-7" stocks. The long/short ratio dropped to the 25th percentile since 2018, effectively resetting positions and creating room for new capital inflows.
The timing of this rebound is particularly nuanced. Hedge funds completed their reduction just before the rally began, and the market then moved sharply higher. Data from JPMorgan (JPM) indicates that positions in hyperscale cloud providers have been quickly rebuilt during the rebound, but they remain far below previous highs. This suggests that significant potential for additional capital inflows still exists.
AI Capital Expenditure Continues to Expand, Approaching $1 Trillion
Investment in AI infrastructure is expanding at an astonishing pace. According to JPMorgan data, market consensus estimates that AI capital expenditure will reach approximately $900 billion this year, an 85% year-over-year increase, and is expected to surpass $1.2 trillion next year. Hyperscale cloud providers are projected to account for about 87% of this spending, and AI-related investments already make up nearly 60% of the total capital expenditure for the S&P 500 index.
This continuous rise in spending reflects both industry confidence and a source of market concern. The rapid expansion of capital expenditure is eroding free cash flow, making the sustainability of the return on invested capital (ROIC) a core investor worry.
Cloud Monetization Accelerates, Order Backlogs Validate Demand Resilience
Despite the immense pressure from capital expenditure, the revenue side of cloud businesses is sending positive signals. AWS grew 37% year-over-year, Azure grew 43%, and Google Cloud grew 82%, all maintaining strong growth rates.
Order backlog data is even more impressive. Google Cloud's backlog stands at $514 billion, a sequential increase of $52 billion for the quarter. AWS's backlog has risen to $496 billion, a 36% sequential increase and nearly 2.5 times higher year-over-year. For Azure, new production capacity is being monetized rapidly upon coming online, with demand consistently outstripping supply. Amazon also disclosed that the payback period for server and network investments is less than three years. This data point helps alleviate market concerns about ROIC and provides fundamental support for the continued expansion of AI capital expenditure.
Free Cash Flow Under Pressure, but Market Focuses on Forward-Looking Indicators
The financial pressure is undeniable. According to JPMorgan data, the combined net profit of hyperscale cloud providers over the past twelve months reached $599 billion, while their free cash flow was only $169 billion, creating a gap of $430 billion. With the exception of Microsoft, most hyperscale cloud providers are expected to remain in a state of negative free cash flow from 2026 to 2027.
However, market pricing mechanisms are forward-looking. Current valuations have already been significantly compressed. The premium of the sector's overall forward P/E ratio relative to the S&P 500 is near a ten-year low. This has to some extent priced in the expectation of short-term cash flow deterioration, setting the stage for a potential valuation recovery.
Positioning Reset Complete, Conditions for Capital Inflows Mature
Changes in positioning have been a key catalyst for this market move. Several weeks ago, hedge funds dramatically reduced their Mag-7 exposure, with the long/short ratio dropping to the 25th percentile since 2018. Both net and gross exposure were reset, leaving the Mag-7 in a clear underweight position.
As the rebound has unfolded, positions in hyperscale cloud providers have been quickly refilled. However, according to JPMorgan data, current levels remain far below previous highs. This indicates that the risk of a crowded trade has not yet re-emerged, and there is still ample room for new capital inflows. Data from Deutsche Bank (DB) also supports this assessment.
From the options market perspective, the previously noted MAGS August 67.5/72.5 call spread has generated good returns. If MAGS can effectively break through the key resistance level of $70, a second phase of the rally could be triggered. If the short squeeze continues, it may be necessary to consider rolling positions to September contracts with higher strike prices.
