Should Tesla be Worried About General Motors?

GM posted 48% year-over-year growth in full-year 2025 EV sales and is now the clear No.2 EV seller in the U.S.; Sierra EV sales rose 32% in Q4 and the Chevy Equinox EV is the top non-Tesla seller while Cadillac is the No.1 luxury EV brand. Tesla's energy business grew revenue ~27% last year and the company is prioritizing energy, robotaxis (Cybercab production slated to start in April) and Optimus humanoid production, which management views as higher-margin, longer-term opportunities. Implication: GM's EV execution could materially gain share and margins in autos, but Tesla's valuation increasingly depends on non-vehicle businesses, so GM's EV gains may not, by themselves, undermine Tesla's broader growth thesis.

Analysis

GM has moved from being a conceptual EV challenger to an operational one; that shifts the battleground from brand halo to unit economics and residual values. Expect ASP compression in mainstream EV segments as legacy OEMs use dealer networks to take share at lower transaction prices, which will compress used-EV residuals and increase depreciation-related warranty/service revenue for both dealers and OEMs over the next 12–36 months. Battery cell mix and supply agreements will determine who sustains margin — players who lock LFP for volume models and NMC for premium lines will widen gross-margin dispersion by several hundred basis points.

Tesla’s valuation is increasingly a call option on non-car businesses that scale with large-scale compute and energy storage demand. That makes semiconductor and AI-infrastructure suppliers a second-order beneficiary if robotaxi/Optimus trajectories materially accelerate; conversely, delays concentrate downside back into auto unit economics. For legacy OEMs the immediate lever is manufacturing fixed-cost absorption — a 5–10% uplift in EV volume at existing plants can move consolidated auto margins meaningfully within 12–24 months.

Key risks: incentive/tax-credit churn, EV residual shocks from aggressive pricing, and a missed software/robotaxi timeline that re-prices Tesla’s multiple quickly. Catalysts to watch on a 3–24 month cadence include (1) announced large-scale battery supply contracts, (2) meaningful margin disclosure by OEMs for EV lines, and (3) any Senate/IRS changes to EV tax credits.

Outcome framework: if GM sustains positive EV gross margins and mitigates residual risk, equity re-rating is plausible; if Tesla delivers early robotaxi/AI revenue, chip/software suppliers re-rate faster than either carmaker. Position sizing should therefore reflect a binary-growth asymmetric view — smaller, optionality-focused longs in Tesla/AI exposure and larger, operational-earnings-focused exposure to GM.

Key Decisions for Investors

• Relative-value pair: Go long GM equity and short TSLA on equal-dollar basis, 12–18 month horizon. Size 2–3% notional net exposure; target 20–40% relative return if GM realizes EV margin uplift of 150–250bps while TSLA misses robotaxi/Optimus monetization. Hard stop: 12% adverse move in the spread or re-evaluate after Tesla posts concrete robotaxi revenue guidance.
• Volatility-hedged LEAP on GM: Buy Jan-2028 GM LEAP calls (delta ~0.30–0.40) sized 1–2% notional as leveraged sideways-to-up EV execution bet. Reward: 3–5x if GM scales volume and margins; risk: total premium loss — hedge by selling nearer-term OTM puts to finance ~25–50% premium.
• Express autonomy compute upside with NVDA call spread: Buy 12–24 month NVDA call spread (buy nearer-OTM, sell higher strike) to capture sustained data‑center/robotaxi spend without full gamma of naked calls. Timeframe 12–36 months; expected payoff if Tesla or major OEMs announce large-scale autonomous fleets — risk limited to premium paid.
• Tail hedge for Tesla downside: Buy 3–6 month TSLA puts (OTM) sized to cover existing long exposure to high-growth tech names or the portfolio’s concentrated Tesla risk. This is insurance: small cost for protection against a binary disappointment in robotaxi/Optimus commercialization that could re-rate TSLA by 20–40%.
