Pundit ClaimsAI claims by Gary Marcus and Ed Zitron, with the evidence

“Of the 114GW of data centers supposedly being built by the end of 2028, only 15.2GW is under construction in any way, shape, or form.”

AI's Economics Don't Make Sense, paragraph 91. The full statement is at the source.

Our reading, the sentence that was checked:

Of the 114GW of AI data centers announced for completion by end of 2028, only 15.2GW is under construction.

From the speaker

  • 114GW
  • by the end of 2028
  • only 15.2GW is under construction
  • in any way, shape, or form

Our interpretation

  • This describes construction status at publication. End-2028 defines the announced project cohort, not a forecast deadline.
  • I use the latest prepublication monthly snapshot: April 2026 through April 28. The post does not identify a measurement date.
  • The surrounding discussion implies capacity measured in total facility power, including early site construction, rather than installed IT capacity.
  • Geography and tracker coverage are unspecified. Both totals must describe the same project population.

Counts as supported if: An independent, dated April snapshot identifies approximately 114 GW scheduled for completion through 2028 and 15.2 GW already under construction within that same population.

Counts as contradicted if: A comparable April snapshot establishes materially different totals, or shows that the two figures refer to different project populations or power measures.

Retrospective: these criteria were written after the outcome was public.

Current assessment

Was it true for the period described?

Outcome: Unresolved

The record was checked, and the evidence available by the cutoff does not settle it.

Scored on a plain reading. The speaker named no measure for this claim, so it was judged on the reading an informed reader would take, stated below under our interpretation. Both reviews had to find that reading fair.

Rationale

Sightline's March 5, 2026 commentary stated that 16GW was due online in 2026 and described only 5GW as "real right now" [e1]. That statement covers an earlier date and a narrower completion cohort, and does not define "real" as under construction [e1]. It therefore neither verifies nor contradicts the claimed April totals of 114GW due through 2028 and 15.2GW under construction [e1].

Limitations

  • The evidence item provides no April project inventory reproducing both claimed totals [e1].
  • Its summary does not establish comparable geography, power measures, or treatment of construction phases [e1].

Evidence (1 item)

  • Context only: Sightline Climate,

    With 16GW due online in 2026, only 5GW is real right now.

    Why it matters here: Sightline publicly described a gap between announced and advancing capacity. This concerns the 2026 cohort at an earlier date and cannot verify April totals covering completion through 2028.

What would settle it

An independently verifiable April 1–28, 2026 tracker snapshot or project inventory showing both totals for the same through-2028 cohort, with consistent geography, power measures and phase-level construction classifications.
