Tesla 的估值凸显了这种不匹配：其预期本益比上升，但基本面却转差；过去 3 年中，倍数扩张约 2/3 可由盈余预测下修所解释，而 Tesla 也是唯一一家在这段期间「已公布」盈余实际下滑的成员。更能说明问题的是现金流与投资需求：Tesla 计划将资本支出（capex）增加到超过原来的两倍，2026 年 capex 预算约 $20 billion，预计将使自由现金流首次自 2018 以来大幅转为负值。过去 5 年 Tesla 产生约 $27 billion 的自由现金流；Amazon 的自由现金流只大约多 50%，但 Amazon 的 capex 约大 9 倍；而除了 Amazon 之外，其余每一家 Magnificent 7 公司仅在过去 1 年创造的自由现金流，就远高于 Tesla 在 5 年合计的水准。即使和同业的支出相比，Tesla 也显得偏小：其 2026 年约 ~$20 billion 的 capex 约为 Alphabet 预测 capex 的 1/9，而 Alphabet 在 2026 年仍预计能产生约 $34 billion 的自由现金流。
这个差距反映了商业现实：Tesla 可以被描述为在纯电池电动车（battery EV）领域占优，且是全球第 2 大卖家，但其全球汽车销量市占仅 1.8%，营业利润率低于 5%；相较之下，其余 6 家约从 11%（Amazon）到接近 60%（Nvidia）。在 AI 与自动驾驶方面，它面对的是预算更庞大、且由营运现金流支撑的竞争者，包括 Alphabet 旗下的 Waymo（据称近期为 robotaxis 募得 $16 billion），以及 OpenAI 等大型 AI 实验室；据报导，OpenAI 甚至可能最早在今年就以 $1 trillion 估值寻求 IPO。这也让 Musk 的资金需求更有脉络：Tesla 表示可能需要「additional funding」，且已 11 次透过公开股权市场筹资，几乎与另外 6 家合计次数相当；同时，据报 xAI 每月烧钱约 $1 billion，而 SpaceX 据报去年在未完全计入 capex 的情况下产生约 $8 billion 的 EBITDA；反观 Tesla 在过去 5 年仅将 39% 的 EBITDA 转化为自由现金流。Tesla 拥有超过 $40 billion 现金，但若持续消耗，或采取合并公司结构，可能令投资人担忧；因此，若 SpaceX IPO 能带来数百亿美元资金，可能成为关键的支撑后盾。
Tesla has long been an awkward fit in the “Magnificent 7,” a label coined in 2023 for the 7 stocks driving S&P 500 gains: Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, and Tesla. That initial year was the only time all 7 truly dominated together, and by 2025 the group’s performance and fundamentals had diverged sharply. Tesla’s renewed push to be seen as an AI, autonomy, and robotics company, alongside Elon Musk’s broader empire reshuffle, makes the comparison more revealing mainly because it highlights what Tesla is not: a cash-generating Big Tech incumbent.
Tesla’s valuation underscores the mismatch: its forward earnings multiple has risen while fundamentals worsened, with about 2/3 of the multiple expansion over the past 3 years explained by falling earnings forecasts, and Tesla the only member whose reported earnings actually declined in that span. Cash flow and investment needs are the bigger tell as Tesla plans to more than double capex, with a 2026 capex budget around $20 billion that is expected to push free cash flow sharply negative for the first time since 2018. Over the past 5 years Tesla generated about $27 billion of free cash flow; Amazon’s was only about 50% larger, but Amazon’s capex was about 9 times bigger, and apart from Amazon, every other Magnificent 7 company made far more free cash flow in just the past year than Tesla made across 5 years. Even against peers’ spending, Tesla looks small: its ~$20 billion 2026 capex is about 1/9 of Alphabet’s forecast capex, while Alphabet is still expected to produce about $34 billion of free cash flow in 2026.
The gap reflects business reality: Tesla can be framed as dominant in battery EVs where it is the world’s 2nd-largest seller, yet it has only a 1.8% share of global vehicle sales and an operating margin under 5%, versus the other 6 ranging from about 11% (Amazon) to nearly 60% (Nvidia). In AI and autonomy it faces competitors with far larger budgets funded by operating cash flow, including Alphabet’s Waymo, which recently raised $16 billion for robotaxis, and major AI labs such as OpenAI, reportedly eyeing an IPO as soon as this year at a $1 trillion valuation. This also contextualizes Musk’s capital needs: Tesla says it may require “additional funding” and has tapped public equity 11 times, nearly as many as the other 6 combined; meanwhile xAI reportedly burns about $1 billion per month, and SpaceX reportedly generated about $8 billion of EBITDA last year without fully accounting for capex, with Tesla converting only 39% of EBITDA to free cash flow over the past 5 years. Tesla has over $40 billion in cash, but sustained drawdowns or a combined-company structure could worry investors, making a SpaceX IPO that brings in tens of billions of dollars a potentially pivotal backstop.
