Data Center Surge vs. Broader CRE Rebound: Which Trend is the Real Market Driver?

The commercial real estate market is clearly thawing. Total U.S. transaction volumes jumped 23% in 2025, hitting a robust $545.3 billion. This marks the second consecutive year of growth, signaling a broad return of investor confidence after a period of caution. The rebound is real, but it's being told in two very different stories.

The headline story is the data center explosion. This sector led the surge with a staggering 274% annual jump in transactions. A massive $23 billion forward sale of a data center under construction was the single biggest driver, inflating the numbers. Even so, the sheer scale of the growth-400% higher than the next fastest sector-has made data centers the viral sentiment of the CRE news cycle. They are the main character in the current market narrative.

Yet the broader recovery is more measured. When you strip out the data center spike, the rebound still looks solid. CRE transactions were up 19% for the year even without that sector. More importantly, every major traditional property type saw gains: office and retail each climbed 26%, senior housing led with a 47% surge, and industrial volumes rose 15%. This shows the momentum is spread across the board, not just concentrated in one tech-driven asset class.

The bottom line is that the market is rebounding, but the data center story may be a headline-driven outlier. The 23% overall jump reflects genuine, broad-based momentum. The 274% data center spike, while impressive, is an extreme outlier that amplifies the overall trend but doesn't define it. For now, the real driver of the CRE recovery appears to be the steady, sector-wide return of capital.

The Data Center Catalyst: Power, Preleasing, and a Megawatt Valuation

The data center boom isn't just a story of high prices; it's a fundamental shift in how the market values and builds real estate. The catalyst is a perfect storm of scarcity, pre-emptive demand, and a new valuation language centered on power, not square footage.

The core driver is a market nearing a hard ceiling. Colocation vacancy is nearing 0%, a record low that is actively constraining economic growth. With virtually no available space, all new absorption must come from preleasing new developments. The pipeline is massive-8 gigawatts of construction-but it's already 73% preleased. This means developers are selling units before a single brick is laid, locking in demand years in advance. The result is a market where financing is easy, construction loans are in demand, and the entire investment thesis is built on future power and occupancy. For now, this preleasing frenzy is the main character in the data center story.

This scarcity is forcing a paradigm shift in valuation. The old "sticks and bricks" model, based on rent per square foot and traditional cap rates, is being replaced by a "megawatt" valuation model. Investors are now underwriting deals based on dollars per kilowatt per month, treating power as the primary asset. This isn't just a new metric; it's a fundamental redefinition of the asset. The shift is so rapid that institutional investors are swiftly increasing exposure, with a record $61 billion in global data center deals this year alone. The focus has moved from tenant diversification to power assurance, with leases now heavily structured around power purchase agreements to guarantee payment.

Even with these high valuations, the demand is so intense that it creates a paradox. A critical vulnerability is the lack of sufficient energy supply, which could slow construction. Yet, this very constraint makes existing data centers more valuable. In a market where every megawatt is pre-sold, the ability to deliver power becomes the ultimate competitive advantage. The sector is essentially betting that the power problem will be solved later, while the immediate need for capacity is so great that it justifies today's premiums. This dynamic, where a fundamental friction (power) actually supports higher valuations, is the most telling sign of the market's viral sentiment.

Market Attention vs. Mainstream Momentum: The Viral Sentiment Gap

The market's attention is firmly fixed on data centers. Search volume and news cycles are dominated by the sector's record deals and megawatt valuations. Yet the real, sustained momentum in commercial real estate is happening elsewhere. This creates a potential misalignment where the viral sentiment may not reflect the broader, more balanced recovery.

On the surface, the data center story is undeniable. The sector saw a 274% annual jump in transactions, and global investment has hit a record $61 billion this year. This frenzy is the main character in the current financial news cycle. But the rebound across traditional CRE is equally strong and more evenly distributed. Office and retail deals each climbed 26% in 2025, while senior housing led with a 47% surge. Even after stripping out the data center spike, total CRE transactions were still up 19% for the year. This isn't a one-off; it's a broad-based return of capital that extends to every major property type.

The strength in traditional sectors is backed by solid fundamentals, not just deal flow. In office, for instance, leasing activity hit a new post-pandemic high last quarter, and downsizing activity has fallen to negligible levels. This shift from contraction to expansion is a key signal of a healthier, more balanced recovery. It suggests companies are making long-term commitments, not just flipping assets. The rebound here is supported by positive leasing and a decline in downsizing, indicating a more mature and sustainable upturn.

This divergence creates a clear headline risk. While the market is paying attention to the data center bubble concerns and the $61 billion construction frenzy, the steady gains in office, retail, and industrial are receiving less fanfare. The intense focus on data centers could skew perception, making other CRE assets appear stagnant or risky when they are, in fact, participating in a genuine thaw. For investors, the real opportunity may lie not in chasing the viral sentiment, but in recognizing that the broader market is rebounding on stronger, more fundamental momentum. The data center spike is a powerful catalyst, but the mainstream CRE rebound is the underlying trend.

Catalysts and Risks: What to Watch for the Main Character

The data center trend is the main character in today's CRE news cycle, but its script is being written by a few critical plot points. The near-term catalysts will determine if this is a sustainable boom or a bubble ready to burst. Watch for any slowdown in preleasing activity or a rise in data center vacancy. With colocation vacancy nearing 0%, virtually all absorption is driven by preleasing. The sector's 8-gigawatt construction pipeline is already 73% preleased, which provides a buffer. But if that preleasing pace cools, it would signal the market's construction frenzy is losing steam. A vacancy rate that creeps above 5% would be a clear warning sign, as it would undermine the entire megawatt valuation model.

The other major constraint is the availability of utility power and financing costs. The sector's rapid expansion is hitting a physical wall. Developers are moving into secondary markets in search of power, but core markets still dominate demand. This scarcity is forcing a shift in financing, with lenders requiring hard deposits earlier in the power procurement process. At the same time, the sector is tapping debt markets aggressively, with debt issuance nearly doubling to $182 billion in 2025. Any spike in interest rates or a tightening of lending standards could quickly cool the financing engine that is currently fueling the boom.

The key risk is a broader market correction. The data center surge is heavily tied to AI sentiment. When AI stocks sold off in November, it rattled the entire tech sector, with shares of companies like Oracle and Broadcom retreating. This shows the headline risk. If concerns about inflated AI valuations or the monetization of the technology persist, the viral sentiment that is propping up data center premiums could sour. S&P Global expects demand to continue growing, but the sector is already seeing investor worry about a bubble. A sharp reversal in sentiment could trigger a pullback in dealmaking, potentially dragging down the entire CRE sector's positive narrative.

For the broader market, the data center story is a powerful but volatile signal. Its strength has amplified the overall CRE rebound, but its fragility introduces new risk. The real driver of the market's stability remains the steady gains across office, retail, and industrial. If the data center bubble bursts, it could sour investor appetite for all CRE assets. For now, the sector's momentum is intact, but the watchlist is clear: monitor preleasing, power supply, and the health of AI sentiment. These are the factors that will decide if the data center main character gets a sequel or a quick exit.
