The price of being late has been renegotiated. This spring, a tenant asking for $1 million for every day a data center opened late was the extreme case, unusual enough that insurance broker Marsh arranged a bespoke policy around one such clause. By October, The Information reports, tenants in fresh negotiations are asking for more than $5 million a day, and justifying the number with lost-revenue estimates they say run higher still.

Read the figure carefully. Five million dollars a day is a demand, stated by the side with the leverage. The tenants are hyperscalers and AI labs, the buyers every developer wants on a long lease, and a demand is how leverage gets expressed before a contract exists. No reporting so far shows a lease signed at $5 million a day, and none shows a dollar of it paid. Larger requested penalties suggest tenants are assigning greater contractual value to timely delivery and seeking to transfer more delay risk to developers.

The schedules underneath

They have data. Goldman Sachs Research, in a May 2026 analysis built on Aterio's facility-level tracking and reported by WebProNews, estimated that about 60% of U.S. data center capacity scheduled for the following year would come online on time, and only about half of what is slated for the following two years. The historical rate, for capacity scheduled over the following four quarters, was about 72%. These are three different forecast horizons, not three readings of the same pipeline. The same analysis expects U.S. data center power demand to rise from 31 GW in 2025 to 66 GW in 2027, with 36.3 GW of capacity due to be added in 2027 alone, against 8.5 GW that actually arrived in 2025 — a measure of how much construction is planned, not a shortfall calculation. Goldman puts a typical build at 18 to 24 months once permits are secured.

A tenant signing a lease against that record is not buying a building. It is buying a probability. Penalties are how the tenant reprices the probability when the record worsens, and the other contract levers reported alongside the headline figure point the same way: rent abatements, liquidated damages, termination rights that trigger on power and building readiness rather than on paperwork milestones.

The one signed example open to inspection shows what this looks like after negotiation. SB Energy, the SoftBank-backed developer building for OpenAI in Ohio, disclosed in its IPO filing that OpenAI receives one free day of base rent for every day of delay at the PORTS-Pike campus, and two free days for every day beyond 90. The arithmetic compounds: 90 days at one-for-one plus 275 days at double comes to 640 days of base-rent credits. Under the disclosed rent-credit schedule, a hypothetical 365-day delay would produce 640 days of base-rent credits before considering any applicable contractual limits or termination provisions. That figure is arithmetic derived from the schedule, not a quoted cash penalty or a documented payment. It is a severe clause, and it is still softer than the new asking price, because it pays in rent the developer had not yet collected rather than in cash it has to find.

Insurance is the tell

The clearest sign that these clauses have become real is that a broker has already insured one. Marsh's delay-in-delivery policy, arranged this spring around that first $1 million-a-day clause, insures the developer against its liability for the fee it would owe its tenant, subject to the policy's terms. That is a different bill from Marsh's older Nimbus facility, launched in June 2025 and raised in January 2026 to reported limits of as much as $2.7 billion, including delay in start-up and business interruption cover. Nimbus is a construction facility: it covers the building and the developer's own losses from a delayed start, and its $2.7 billion is a reported capacity figure, not a pool set aside for tenant penalties. One product insures the building. The newer one insures the promise — for the one developer who bought it. Nothing in the reporting shows cover of that kind yet written against the new $5 million-a-day demands.

Underwriting that promise is not simple. Mathews put the scale plainly in a March webinar: a single site can hold "a $4 billion data centre with $10 billion worth of equipment in a single site facility" — his illustration of the values concentrated in one facility, not a valuation of any campus in this story. Spreading risk of that size across multiple carriers, he said, would be the trend. If a developer agreed to a $5 million daily penalty with no applicable cap or grace period, a hypothetical 30-day delay would create $150 million in contractual exposure before considering other terms — before any argument about whether the delay was the developer's fault, the utility's, or the permit office's.

For readers, the practical change is in what a lease announcement now contains. A campus described as fully leased to a hyperscaler may carry a meter that starts running the day it misses its date, an insurance premium priced against Goldman's on-time odds, and a developer whose margin depends on a grid connection it does not control. The next time a major campus slips, the interesting disclosure will not be the new date. It will be which of those three parties writes the cheque, and whether the clause that priced the delay was the $1 million version from spring or the $5 million version from this autumn.
