How big could Tesla's revenue be by FY2031?

0. Summary

Mid scenario: ≈$135.4–182.7B revenue in FY2031 [A] (Low ≈$77.3–87.0B / High ≈$215.2–295.9B), built bottom-up in the §5 driver bridge, from FY2025 $94.8B (10-K 0001628280-26-003952).

What the filings show: the fastest-growing reported segment over FY2022–FY2025 is Energy, not FSD/robotaxi. Energy revenue went from $3.9B (FY2022, 10-K 0000950170-23-001409) to $12.8B (FY2025, 10-K 0001628280-26-003952), a 48.4% CAGR (derived). In Q3 2026 Energy generation and storage revenue was $2.9B of $28.0B total revenue (10.3%, derived), down 15.6% yoy from $3.4B in Q3 2025 (8-K 0001628280-26-066738, Ex. 99.1, unaudited, 10-Q pending; Q3 2025: 10-Q 0001628280-25-045968; derived). Company-wide, revenue rose 25.5% yoy in Q2 2026, while operating income was $0.4B (1.4% margin) and free cash flow was −$1.1B (10-Q 0001628280-26-049270; free cash flow derived: operating cash flow − capex = $4,697M − $5,789M). In Q3 2026, company-wide revenue was $28.0B (−0.2% yoy, derived), operating income $0.7B (2.6% margin, derived) and free cash flow $1.5B (derived: operating cash flow − capex = $6,263M − $4,732M; 8-K 0001628280-26-066738, Ex. 99.1, unaudited, 10-Q pending).

1. Products and markets (SEC)

Deliveries: FY2024 1,789,226; FY2025 1,636,129 (8-K 0001628280-25-000007 / 0001628280-26-000016). Q3 2026 486,532 vs Q3 2025 497,099 (8-K 0001628280-26-064366 / 0001628280-25-043530): −2.1% yoy.

Q2 2026 (10-Q 0001628280-26-049270): revenue $28.2B (vs $22.5B, 10-Q 0001628280-25-035806); operating income $398M; capex $5.8B; free cash flow −$1.1B (derived: operating cash flow $4,697M − capex $5,789M); energy revenue $3.1B; storage deployed 13.5 GWh (8-K 0001628280-26-049213); Active FSD Subscriptions 1.48M (8-K 0001628280-26-049213; upfront purchases + subscriptions, excl. trials); deferred revenue (software, connectivity, Supercharging, OTA) ≈ $4.05B (rounded in filing, 10-Q 0001628280-26-049270).

Q3 2026 per 8-K earnings release (unaudited), 10-Q pending (8-K 0001628280-26-066738, Exhibit 99.1, filed 2026-10-21): total revenues $28,046M (Q3 2025: $28,095M, 10-Q 0001628280-25-045968); automotive revenues $20,560M; energy generation and storage revenue $2,881M (Q3 2025: $3,415M, 10-Q 0001628280-25-045968); services and other revenue $4,605M; gross profit $5,494M (19.6%, derived); income from operations $718M (2.6%, derived; Q3 2025: $1,624M, 10-Q 0001628280-25-045968); operating cash flow $6,263M; capex $4,732M; free cash flow $1,531M (derived: operating cash flow − capex); storage deployed 13.7 GWh; Active FSD Subscriptions 1.74M (company definition: upfront payment and monthly subscriptions, excluding free trials).

TTM to Q3 2026 = $103.6B (derived 24,901 + 22,387 + 28,236 + 28,046 = $103,570M; the Q3 2026 component is unaudited, 10-Q pending, 8-K 0001628280-26-066738). 9M 2026 revenue = $78.7B (derived 22,387 + 28,236 + 28,046).

Not disclosed: FSD revenue, robotaxi fleet/miles, ASP by model.

1b. Core technology

In 5 sentences: Tesla has three core technologies: battery/powertrain manufacturing (cars and stationary storage), a vision-only driving software stack trained on fleet data, and, early on, humanoid robots [A]. The key metrics are cost per kWh and cost per vehicle (manufacturing), and safety-relevant miles per intervention for autonomy, which Tesla does not disclose in SEC filings, so that curve is unknown. The binding constraints are cell supply/chemistry (partly bought from suppliers, partly in-house), training compute, and above all regulators who grant driverless permits [A]. Tesla owns vehicle design, factories, software and distribution, and buys a large share of cells and chips [A]. Company-wide gross margin was 18.0% in FY2025; segment margins are not shown here (10-K 0001628280-26-003952, derived). Robotaxi and Optimus roadmaps require breakthroughs that SEC data cannot confirm, so they stay at low assumption bands [A].

2. Decomposition and unit economics

• Revenue = Automotive (deliveries × ASP [not disclosed] + regulatory credits + services/software) + Energy (GWh deployed × $/GWh [not disclosed]) + FSD/robotaxi (in Automotive/Services; not disclosed separately).
• The real drivers: (1) deliveries (flat-to-down for 2 years), (2) auto price/margin, (3) energy storage GWh, (4) FSD take rate and price, (5) robotaxi regulation and fleet.
• Unit economics FY2025 (10-K 0001628280-26-003952): gross profit $17.1B = 18.0%; operating income $4.4B = 4.6%; free cash flow $6.2B (derived: operating cash flow $14,747M − capex $8,527M) = 6.6%; capex $8.5B = 9.0% of revenue (derived).
• Competitive position: see §5b.
• Spending vs. disclosed revenue: Tesla's filings describe autonomy and Optimus as strategic priorities (FY2025 10-K, Part I, Item 1 "Business – Overview", 0001628280-26-003952). Q2 2026 capex was $5.8B against operating income of $0.4B; no robotaxi or Optimus revenue is disclosed. We therefore keep robotaxi/Optimus at low assumption bands [A]. In Q3 2026 capex was $4.7B against operating income of $0.7B (8-K 0001628280-26-066738, unaudited, 10-Q pending); still no robotaxi or Optimus revenue line is disclosed.

3. Market from first principles

• Auto [A]: global car units × EV share × Tesla share × ASP. No checked external figures, so it stays [A].
• Energy [A]: grid-storage GWh demand × $/GWh. Tesla deployed 13.5 GWh in Q2 2026 (8-K 0001628280-26-049213) and 13.7 GWh in Q3 2026 (8-K 0001628280-26-066738, unaudited, 10-Q pending). TAM inputs are [A].
• FSD/robotaxi [A]: no external market-size figure is used on this page; the addressable market is not sized here. FSD/robotaxi ranges are Hollsteen assumptions [A]; method summary: fleet × paid miles × $/mile, see 'Methodology' below. FY2031 FSD + robotaxi ranges [A]: Low ≈$1.29–2.95B / Mid ≈$5.42–20.69B / High ≈$15.23–50.92B.

4. What has to happen

Pre-mortem (High scenario fails): (1) robotaxi stays supervised or geofenced; the FSD contribution stays small [A]. (2) Chinese EV price competition keeps auto margins near zero [A]. (3) Capex stays high (Q2 2026 $5.8B, 10-Q 0001628280-26-049270; Q3 2026 $4.7B, 8-K 0001628280-26-066738, unaudited, 10-Q pending) without revenue to match, so free cash flow stays weak [A].

Low scenario (strongest case against growth): revenue has been flat for three years ($96.8B → $97.7B → $94.8B, FY2023–FY2025; 10-K 0001628280-24-002390 / 0001628280-25-003063 / 0001628280-26-003952). Deliveries are still down yoy in Q3 2026 (8-K 0001628280-26-064366), Q3 2026 revenue was −0.2% yoy and the operating margin was 2.6% (8-K 0001628280-26-066738, unaudited, 10-Q pending; derived). In this scenario, Tesla would be an automaker without revenue growth plus a fast-growing but small energy business. Named shock triggers on top of that: (a) regulatory/liability: a serious robotaxi accident, a recall or a regulatory investigation could stop permits, freeze FSD take rates and add liability costs [A]. (b) tariffs/subsidies: tariffs on imported cells and components hit energy storage costs and volumes, and EV subsidies expire, pushing auto volumes and ASP down [A]. Then auto shrinks and energy stalls: ≈$77.3–87.0B FY2031 [A], below both FY2025 ($94.8B) and TTM to Q3 2026 ($103.6B, derived; incl. unaudited Q3, 10-Q pending; 8-K 0001628280-26-066738).

Low-scenario bridge FY2031 ($B, [A]): FY2026E $103–$108B + Auto volume/ASP fall as EV subsidies expire [A] −$12 to −$10B + Robotaxi/FSD regulatory freeze (regulatory, liability) [A] −$6 to −$5B + Energy storage tariffs on cells [A] −$5 to −$4B + Services/other shrink with fleet [A] −$2.7 to −$2B = $77.3–$87.0B (sum checked: 103 − 12 − 6 − 5 − 2.7 = 77.3; 108 − 10 − 5 − 4 − 2 = 87.0). High-end steps ≤ low-end steps (shock chain from the current-year estimate).

5. Scenarios (revenue, $B)

FY2026E [A] ≈ $103–108B = 9M 2026 revenue $78.7B (derived: Q1 $22,387M, 10-Q 0001628280-26-026673 + Q2 $28,236M, 10-Q 0001628280-26-049270 + Q3 $28,046M, 8-K 0001628280-26-066738, Ex. 99.1, unaudited, 10-Q pending = $78,669M) + implied Q4 2026 ≈ $24.3–29.3B [A] (derived: $103,000M − $78,669M = $24,331M to $108,000M − $78,669M = $29,331M). For comparison, Q4 2025 revenue was $24.9B (derived: FY2025 $94,827M per 10-K 0001628280-26-003952 − 9M 2025 $69,926M (Q1 $19,335M, 10-Q 0001628280-25-018911 + Q2 $22,496M, 10-Q 0001628280-25-035806 + Q3 $28,095M, 10-Q 0001628280-25-045968) = $24,901M). Recheck this estimate after the Q3 2026 10-Q is filed.

Low-scenario test: the Low top ($87.0B) is below TTM revenue to Q3 2026 ($103.6B, derived; incl. unaudited Q3, 10-Q pending; 8-K 0001628280-26-066738). ✓

Driver bridge FY2031 (revenue, $B; all values are Hollsteen assumptions [A] unless marked SEC)

This page models revenue only. It does not estimate a share price, fair value or market capitalization, and it makes no statement on whether the stock is over- or undervalued.

Why the High scenario still reaches ≈$215–296B with only ≈$15–51B FSD/robotaxi: it needs auto to grow ~9–10%/yr (deliveries ~3.5–3.9M) and energy to compound ~30–35%/yr, plus early Optimus sales. That requires three conditions at once; we consider this scenario the least likely of the three [A].

Sanity checks: Tesla's own FY2020–25 CAGR was 24.6% ($31.5B FY2020, 10-K 0001564590-21-004599 → $94.8B FY2025, 10-K 0001628280-26-003952; derived), but −1.0% a year over FY2023–FY2025 ($96.8B → $94.8B, derived: (94,827 / 96,773)^(1/2) − 1). Base rate: of 32 covered USD-reporting companies with $5.0–<50.0B revenue at the start of their latest 5-year window, 8 had a 5-year revenue CAGR > 20% (NVDA, MU, UBER, AMD, TSLA, APH, AVGO, XYZ) (derived by Hollsteen from SEC revenue of covered companies, FY2020–FY2025 for companies whose latest fiscal year is FY2025 and FY2021–FY2026 for those whose latest is FY2026; data as of 2026-10-22). 'Covered' = the 100 companies in the Hollsteen universe. Denominator: 100 − 16 without a computable 5-year CAGR (no SEC value for the start year, or a recast revenue basis) − 7 with a non-USD reporting currency (ASML, SAP, SPOT, TSM, ASX, UMC, ERIC) − 45 USD reporters whose start-year revenue is outside $5.0–<50.0B = 32. MU's window ends with FY2026 ($133.2B, 10-K 0000723125-26-000023, filed 2026-10-09; 53-week year) vs FY2021 $27.7B (10-K 0000723125-21-000065): 36.9% (derived). A 5-year CAGR is a start-to-end rate, not growth in every year (TSLA is in the list despite flat FY2023–FY2025).

The High top (~21–23%) sits in that tail.

5b. Product, distribution and competition

Robotaxi competition (context only). Hollsteen does not yet have filed or regulator-published operating data for Waymo, so we make no comparison of who leads. Uber figures are from its FY2025 10-K (0001543151-26-000015).

Unit cost: not disclosed for either of the two; no comparison made.

Regulatory position: not assessed on this page.

Competitive-position notes (Hollsteen assessment [A])

Indicators to watch: Tesla unsupervised permits in multiple metros (8-K / state DMV).

6. Methodology

Revenue scenarios are built bottom-up per driver (auto, energy, FSD software, robotaxi, Optimus) [A]. Robotaxi revenue = fleet × paid miles per vehicle × $/mile [A]; FSD software = users × price [A]; ranges are Hollsteen assumptions, not company guidance. Scenario totals are the exact sums of the driver ranges. CAGRs are derived from the FY2025 SEC figure and from the FY2026E midpoint [A]. The Low scenario is a step bridge from the FY2026E estimate; Mid and High are driver sums and do not depend on the FY2026E estimate.
