Resolution criteria

• Resolve YES if Argonne National Laboratory’s Light‑Duty Electric Drive Vehicles Monthly Sales Updates reports U.S. new light‑duty PHEV sales for November 2025 strictly greater than 23,800. Use the first value Argonne publishes for Nov 2025 on this page (or a directly linked PDF/dashboard), ignoring later revisions made more than 7 days after first publication. If exactly 23,800, resolve NO. Link: https://www.anl.gov/esia/light-duty-electric-drive-vehicles-monthly-sales-updates. (anl.gov)

• If Argonne has not published a November 2025 PHEV figure by January 31, 2026, resolve using the Argonne PEV Dashboard (https://evdashboard.esia.anl.gov/) or, if inaccessible, the YCharts series “Plug-in Hybrid Electric Vehicles (PHEV) Total Sales” (https://ycharts.com/indicators/plug_in_hybrid_electric_vehicles_total_sales), which sources Argonne; use whichever clearly shows the number. (evdashboard.esia.anl.gov, ycharts.com)

• “Sales” means unadjusted U.S. new light‑duty PHEV sales (cars and light trucks ≤10,000 lbs), as defined by Argonne; excludes HEVs and BEVs. (anl.gov)

Background

• Argonne’s latest published snapshot (June 2025) shows 19,716 PHEVs sold (PEVs 113,433 total; 9.04% LDV share). (anl.gov)

• Recent reference points: May 2025 PHEV sales 28,892; June 2024 22,338 (YCharts series sourced to Argonne). (ycharts.com)

• Argonne notes it uses Wards Auto as the reference for monthly E‑drive sales data (since Oct 2019). (anl.gov)

Considerations

• Different datasets (e.g., registrations vs. sales) can diverge; this market resolves only on Argonne’s sales series. (anl.gov)
