Resolution criteria

• Resolves YES if Argonne National Laboratory’s Light-Duty Electric Drive Vehicles Monthly Sales Updates reports U.S. new light‑duty PHEV sales for January 2026 strictly greater than 22,900 (>22,900). Resolves NO if the value is ≤22,900. Use the “PHEV sales” figure for January 2026 shown on that page or its downloadable spreadsheet. Use the latest value available on that Argonne page as of April 30, 2026; later revisions are ignored. (anl.gov)

• If Argonne relocates the page, use its successor Argonne-hosted monthly sales page. If January 2026 data is not posted by April 30, 2026, use the U.S. Joint Office “Monthly EV Minute” for January 2026 that cites Argonne; if still unavailable by May 31, 2026, resolve N/A. (driveelectric.gov)

Background

• Argonne compiles monthly U.S. sales of HEVs, PHEVs, and BEVs (light‑duty ≤10,000 lbs) and publishes summary tables and a downloadable spreadsheet. (anl.gov)

• Recent PHEV monthly volumes have hovered around the low‑20Ks: June 2024 = 23,648; July 2024 = 22,320; November 2024 = 23,513. June 2025 dipped to 19,716. (driveelectric.gov, anl.gov)

Considerations

• Auto sales are seasonally weak in January, which can depress PHEV totals relative to late‑year months. Revisions to Argonne’s monthly figures are occasional; the cutoff above limits ambiguity. (anl.gov)
