Planner reasoning

This is a long-horizon question about US (or global) EV light-duty sales share exceeding 30% by Jan 2030. The key is the current EV share trajectory and growth rate, projected forward, plus policy and consumer-adoption factors. The Kalshi price is the anchor, and recent news/data on EV market share trends drive the estimate.

# Event EV market share in 2030 — global light-duty vehicle share above 30% (January 2030 reading) # Outcomes to forecast - **Yes**: EV share of light-duty vehicle sales > 30% in Jan 2030 - **No**: EV share ≤ 30% # Kalshi market anchor **Current YES price: 43%** (EVSHARE-30JAN-30) - 7-day change: +2pp | 30-day change: -2pp (slight net drift down over month, modest recent uptick) - Avg daily volume: 44 contracts (low liquidity; 59-day range: 37–55%) - Low volume means price is noisy and moveable # Sub-question answers 1. **Current EV share of light-duty vehicle sales (US vs. global)?** — Global share was ~19% in 2024, rising to ~23% in H1 2025, and ~27% for full-year 2025 [ICCT]. US-only share is far lower: ~9–10% in 2025, dropping to ~6% in Jan 2026 after tax credit expiry [ICCT, ABC News]. The market description says "electric light-duty vehicles sold" without specifying geography — resolution likely global given no US-only restriction. 2. **YoY growth trajectory (past 3–5 years)?** — Global share grew ~4 pp/year: ~10% (2022) → ~15% (2023) → ~19% (2024) → ~23% H1 2025 [ICCT]. US growth has stalled and reversed. China accelerating (~52% share in 2025) [ICCT]. 3. **Major 2030 forecasts?** — IEA Stated Policies Scenario (2025): global >40% by 2030; Incorrys/IEA-derived: ~41% [IEA, Incorrys]. Global EV Volumes: 40.4% [Autovista24]. US-only: BNEF 19–27%, IEA 20%, Cox ~25%, Princeton 24% [BNEF, IEA, Cox, Princeton/Electrek] — all US forecasts below 30%. 4. **Policy changes affecting outlook?** — US: EV tax credits eliminated (One Big Beautiful Bill Act, effective Oct 2025); EPA GHG/CAFE standards rescinded; California EV mandate revoked [CRS, Harvard EELP, InsideEVs]. These reduce US share ~16–25 pp vs. prior forecasts. China and Europe continue aggressive support, sustaining global momentum. 5. **Headwinds keeping share below 30% globally?** — US collapse (sales down 20% MoM in Jan 2026, Q4 2025 US EV sales -45% YoY) [Rest of World, ABC News]; $65B+ OEM EV writedowns signaling strategic retreat [Enkiai]; global forecasts still exceed 30% mainly because China (~80% projected) and Europe (~60%) dominate volumes [IEA]. # Key facts (high-confidence, factual) 1. [ICCT] Global LDV EV share: 19% (2024), ~23% H1 2025, ~27% full-year 2025 2. [ICCT] US EV share ~9% in 2025; dropped to ~6% in Jan 2026 post-credit expiry 3. [IEA 2025] Global IEA Stated Policies projects >40% by 2030 globally 4. [IEA] China projected ~80%, Europe ~60%, US only ~20% by 2030 5. [CRS/Congress] EV tax credits terminated for vehicles acquired after Sept 30, 2025 6. [Harvard EELP] Trump admin rescinded GHG vehicle standards in Feb 2026 7. [BNEF/InsideEVs] US 2030 forecast revised from ~46–48% to 19–27% 8. [ABC News] US EV sales -20% MoM in Jan 2026 after credit expiry # Cross-market signals - **Kalshi related**: No other EVSHARE series markets found; Ford US sales 2026 market (12% probability for >2.15M) suggests auto market headwinds - **Polymarket**: No relevant EV market share markets found (keyword false positives only) - **Sportsbook**: N/A # Analyst opinions and speculation - The question is ambiguous on geography. If **global**: IEA, BNEF, and ICCT trajectories all point above 30% comfortably (~40%+ projected). If **US-only**: virtually all revised forecasts place 2030 share at 19–27%, below the threshold. - The ~4 pp/year global growth rate from 27% in 2025 implies ~47% by 2030 if linear — well above 30%. - US slowdown is significant but US is ~15–17% of global LDV market; China alone (~30% of global LDVs at 80% EV penetration) would push global above 30%. # Directional lean per outcome - **Yes (>30% globally)**: Strong support — current trajectory at 27% (end-2025), IEA/BNEF project 40%+, China/Europe momentum robust, only needs ~3pp more growth over 4+ years - **No (≤30%)**: Would require major China/Europe reversal or US-style policy collapse globally; current data makes this unlikely on a global basis # Gaps / Unknowns - **Critical ambiguity**: Market description doesn't specify US or global — resolution rule is unclear; this drives the entire forecast - If US-only: No is heavily favored (~75%); if global: Yes is heavily favored (~75–80%) - Kalshi's 43% price may reflect uncertainty about geography + possibility the market resolves on US data # Calibration anchors - **Kalshi current YES: 43%** — suggests market is pricing geography ambiguity heavily - If global: ~75% Yes (IEA/BNEF consensus well above threshold, strong trajectory) - If US-only: ~20–25% Yes (all major forecasts below 30% post-policy rollback) - Kalshi's 43% is roughly consistent with ~60% probability it resolves globally AND global exceeds 30%, blended with US-resolution risk

1. Both forecasters treat the global vs. US ambiguity as roughly a 50/50 split in resolution probability, but neither justifies this prior. The market description says "EV market share in 2030" without any US qualifier, and global is the conventional default for ICCT/IEA reporting; a more defensible prior might weight global resolution at 65–70%, pushing Yes well above 50% even before adjusting for trajectory. 2. Neither forecaster adequately stress-tests the China/Europe scenario for catastrophic downside. The brief notes China at ~52% share in 2025 projecting ~80% by 2030 and Europe at ~60%; even a severe China policy reversal (e.g., subsidy elimination) would need to be dramatic and sustained to prevent global share from crossing 30%, yet neither forecaster quantifies how large a China shock would need to be to flip the outcome. 3. Both forecasters underweight the trajectory math: global share was ~27% at end-2025, and the question resolves in January 2030 — only ~4 years away. The brief notes ~4 pp/year historical growth; even at half that rate (~2 pp/year), the share reaches ~35% by 2030. Neither forecaster explicitly engages with how low the required growth rate is to clear 30%, which should raise Yes confidence meaningfully on the global interpretation. 4. The Kalshi anchor of 43% is being treated as informationally rich, but the brief explicitly flags it as low-liquidity (44 contracts/day, 59-day range of 37–55%). Both forecasters anchor too heavily on this noisy price rather than treating it as a weak prior to be overridden by the strong fundamental evidence. 5. Neither forecaster considers the possibility that the market resolves on a specific data source (e.g., ICCT global tracking) that would almost certainly show >30% given current trajectories, versus a US-centric source — this distinction matters for the resolution probability and is left entirely unaddressed. 6. Forecast 1 assigns No=0.55 despite acknowledging the global trajectory strongly favors Yes; this creates an internal inconsistency where the forecaster's own stated conditional probabilities (~75% Yes if global, ~20–25% Yes if US) would require the US-resolution probability to be ~65%+ to justify No being favored — a prior neither forecaster defends.

60% (38% confidence)

Yes: 60% No: 40%

The market description lacks any US qualifier, and global is the conventional default for EV share reporting (ICCT/IEA), so resolution likely weights global at ~65%. On a global basis, current share (~27% end-2025) needs only modest growth to clear 30%, with IEA/BNEF projecting ~40%+; even at half historical growth it exceeds 30%. US-only resolution would favor No, but that's the lower-probability interpretation. Blending ~65% global-resolution (with ~80% Yes) against ~35% US-resolution (with ~20% Yes) yields ~60% Yes, above the noisy low-liquidity Kalshi anchor of 43%.
