Published erratum
A G42 chip purchase authorization was misattributed to Stargate UAE Phase 1
What the site showed
An earlier correction replaced Epoch’s power-derived estimate of 100,000 chips with 35,000 GB300 chips, then derived 87,500 dense PFLOPS and 88,428 H100 equivalents. Those values appeared as Phase 1 capacity even though the cited authorization applied to G42 as a company.
Correction
The facility chip count and both derived performance values are withheld. Commerce’s November 19, 2025 statement authorizes purchases equivalent to up to 35,000 GB300 chips for G42; it does not specify how many were installed at this facility. G42’s October 16 construction update describes a first 200 MW phase within the 1 GW Stargate cluster and wider 5 GW campus, with delivery planned for 2026. These sources do not establish commissioning or an installed inventory.
Why it happened
The correction assigned G42’s company-wide purchase authorization to Stargate UAE Phase 1 without evidence of that allocation. References to the 200 MW phase supplied no chip inventory. A calculation based on assumed power shares was used to corroborate the count, although it could only test whether the assumed count fit those power assumptions.
Changes made
The numerical corrections layer withholds all three unsupported values and retains the original source record. The separate power correction for cumulative-campus double counting remains in place. Threshold estimates exclude this record when both corrected chip count and power are absent, and tests reject fallback to raw values after a null correction. A future chip-inventory correction requires evidence for the facility, hardware and quantity.
Commerce’s 19 November 2025 statement authorized G42 to purchase up to 35,000 GB300-equivalent chips but did not allocate them to Stargate UAE Phase 1. The former 35,000-chip correction and the compute figures derived from it have been withdrawn. Epoch’s original chip count was estimated from power with unconfirmed hardware, so it cannot establish a replacement inventory. G42’s 16 October 2025 update described the first 200 MW as under construction for planned delivery in 2026. The separate campus power correction is unchanged.
Changing chip-data coverage appeared as a shipment decline and a concentration trend
What the site showed
The upstream chip-flow chart ended with an apparent fall in cumulative shipments. Its final quarter contained only Nvidia and Google observations, all marked incomplete by the source; other designers disappeared into zero-filled series. Cambricon records with separate annual start dates were also mixed into the cumulative stack. The designer-concentration chart used the same changing population and described its early single-designer coverage as near-monopoly. Its incomplete marker appeared in a tooltip without withholding the plotted point.
Correction
The shipment and concentration figures now cover the same reported designers, with a consistent start date for each chip series. Quarters marked incomplete, or missing chips previously reported, are excluded and identified; gaps within the series remain visible. Growth is calculated from the displayed endpoint totals. Cambricon’s two annual observations are shown separately with their source windows. The figures cover the designers reported by the source; no raw source value was changed.
Why it happened
Both charts grouped records by end date without checking whether their start dates and covered populations were comparable. Missing rows became zero, and the source’s incomplete flag was ignored. The concentration chart used designer count to check coverage, so it missed partial periods with the usual number of designers and admitted annual observations into a cumulative series.
Changes made
Both charts use the same checks for source windows, incomplete quarters and missing records. Tests cover changes in start dates and mixed completeness flags; unknown completeness excludes a quarter. Screen and print use the same records, with excluded periods identified. The HHI band calculation is unchanged.
On the training-cost disclosure figure, Inflection-2 appeared on the rung for runs whose lab named only the hardware or the model size, despite retaining an explicitly reported FLOP value. Two CHIPS award records also lost their tax-credit disclosure qualifiers and other structured notes. Their failed-citation warnings remained in the database but did not reach the training-cost comparison, the facility pages or the sovereign embed.
Correction
The affected metadata was restored from retained ingestion records and the original ingestion code, after matching each record’s identity, numerical fields and citation. Historical failed-citation warnings remain attached to their original sources and check dates. No numerical value or source URL changed. The retained files are not a pre-overwrite database backup and cannot recover unknown database-only additions.
Why it happened
The URL checker appended warnings as though every metadata column held an array. On columns that held objects, this replaced disclosure details with the warning array. The training-cost comparison, facility pages and sovereign embed also omitted warnings when selecting their data; the compact facility data loader discarded every quality flag.
Changes made
The URL checker now preserves each column’s declared object or array format. It writes only when the stored value and citation still match the values it read, and requires exactly one updated row. The restoration is recorded in the database migration ledger. Training comparisons and exports retain warnings for the individual sources; facility HTML and Markdown and the sovereign embed also retain check dates. CHIPS funding and facility pages attach warnings to the individual award citations, including in print. Published warnings omit source locators held under licence. BIS warning visibility was left for a separate correction.
Sovereign-AI gap allocations were published without the figures needed to reproduce them
What the site showed
The Inflation view assigned percentages of each programme’s announced-versus-disbursed gap to named causes, classified programmes as having or not having a gap, and summarised those allocations across the portfolio. Source links and confidence labels accompanied the allocations.
Correction
The archived manifest does not contain the announced, disbursed and cause-specific amounts needed to reproduce those percentages or the gap classifications. The quantitative matrix and its summaries are withdrawn. The separate programme records, government-budget comparisons and funding ledgers remain available; the archived allocations and their citations are retained for review. No replacement percentages have been estimated.
Why it happened
The review checked that the drafted percentages summed to 100 and carried citations, without checking the underlying amounts or whether those citations supported the allocations.
Changes made
The data loader withholds the archived allocations. Restoring them requires compatible amounts, units and dates, a reproducible calculation, and an independent reading of the cited sources. Automated checks verify that the supporting amounts are present and add up; editorial review must establish that the sources support them. The correction record and methodology retain the withdrawal notice; the former Inflation URL redirects to the programme register. The correction also covered the former Sovereign AI Brief, retired in September 2026.
Changing the stress-index weights recalculated the chart while downloads continued to use the original equal-weight history. With every weight set to zero, the historical composite reverted to that original series. Rounded score columns also prevented some downloaded composite values from being reproduced exactly. A fixed ten-per-cent input perturbation was presented as a confidence assessment without an uncertainty model.
Correction
Downloads now include the selected normalized weights, their raw sum and the component scores at full precision. These reproduce the displayed one-decimal composite. Setting every weight to zero removes the composite and its exports; the four component series remain available. The unsupported confidence assessment was removed. No confidence interval is calculated.
Why it happened
The chart and download used different arrays. When the weights summed to zero, separate fallback calculations restored the original equal-weight series. Rounding the exported scores also discarded precision needed to reproduce the composite.
Changes made
The chart and download now use the same recalculated history and require a positive sum of weights. Tests vary the weights and reproduce the composite from its exported inputs; they also check that the all-zero state retains the component series without a composite. Export descriptions name the source series used in the calculation.
Supply-chain records kept figures their new public citations did not support
What the site showed
Supply-chain records relabelled to cite public relationship evidence retained numerical attributes from an earlier import. Scores, annual values and price correlations could consequently appear beside a public citation that did not establish those quantities. A sole-source flag left at the importer’s default of no, and an empty list of alternative suppliers, could also read as verified statements about sole sourcing and alternatives. The values affected graph details, ranking and country aggregates.
Correction
The affected relationships and public citations remain available. Their inherited scores, shares, values, correlations, volumes, lead times, sole-source flags, alternatives and notes are withheld by both the application data loader and the public database view. Unknown fields remain empty, and raw records are preserved. Records from other sources retain their existing publication rules; their individual fields were outside this correction’s source review.
Why it happened
The import changed provenance labels and URLs without checking the accompanying attributes against the new citations. Graph details and aggregates then treated the public citation as support for the entire record. The public database view separately lacked a filter for licensed-source rows and ran with its owner’s privileges, which bypassed the underlying table’s row-level security.
Changes made
The application loader excludes licensed-source rows and withholds unsupported attributes before combining or ranking records, including in country and bilateral totals. Cascade simulations identify their default values as model assumptions. On 6 September 2026, the public view received the same filters, and anonymous and authenticated users lost direct access to the ten guarded base-table columns. Raw records were unchanged. Tests distinguish eligible zero, false and empty values from unsupported imported values and check both the old and replacement view populations. Publication of a withheld field requires independent source verification and an explicit change to the filter.
Core Scientific’s 26 February 2025 release gives approximately 260 MW of critical IT load for the Denton site. This cluster record repeats that site capacity. Totals use the 262 MW site record, with both figures available in the campus comparison. The cluster’s 100,000 accelerators remain in compute totals.
This is a second record of Google’s Papillion data center. Capacity totals use the 237 MW site record; the 250 MW figure remains in the campus source comparison.
The Prometheus cluster and the New Albany campus describe the same site at different scopes. Capacity totals use the campus record’s 631 MW; the cluster’s 1,281.28 MW estimate remains in the source comparison. Its 500,000 accelerators remain in compute totals.
