Colocation Insights

  • Large tech, neocloud and enterprise demand in H1 increased rental rates and drove the overall vacancy rate to 2.2%.
  • Strong preleasing for new supply has led to a sub-10% vacancy rate for projects delivering by year-end 2027.
  • No contiguous data center space of 5 MW or more will be available this year, and all large contiguous projects are expected to deliver in late 2027 at the earliest.

Market Trends

  • Developers are increasingly prioritizing power availability over traditional location considerations for new data center sites.
  • Anticipated revisions to Illinois’ Biometric Information Privacy Act this year have led hyperscalers to consider more politically friendly markets.
