SpaceXAI 上季度资本支出为 180 亿美元,其中 160 亿美元用于 AI。1 2
这是一个巨大的数字。Amazon 上季度支出 531 亿美元,Alphabet 449 亿美元,Microsoft 410 亿美元,Meta 311 亿美元。3 SpaceXAI 仅 AI 资本支出就接近 Microsoft 总支出的 40%。
支出增长的斜率也相当。4
区别在于谁来买单。Microsoft 用运营现金流为其建设提供资金,且还有余量,达到资本支出的 155%,Meta 也以六个百分点的优势达标。其他所有公司则靠借款或发行股票:Oracle 89%,Alphabet 87%,Amazon 84%,CoreWeave 39%,SpaceXAI 12%。5
两类投资者都已下调了对该计划的估值。SPCX 于 8 月 5 日收于 108 美元,比 135 美元的 IPO 发行价低五分之一,仅为 6 月 16 日峰值的一半。6
信用市场也认同,而且放贷期限越长,认同度越高。6 月发行的 250 亿美元首只债券的每一档都低于面值交易:2031 年到期债券为每美元 98 美分,2056 年到期债券为 90 美分。7
SpaceXAI 正在奋力追赶:它拥有数据中心,训练出了 Grok 4.5,在智能指数上排名第四,与榜首仅差六分,8 并且有数百万开发者在使用 Cursor。9
此次 IPO 证明了该公司拥有巨大的资本成本优势。10
现在的问题是,这一优势能否维持足够长的时间,让 AI 业务追平其他业务。

SpaceX 公布 2026 年第二季度业绩。按业务板块划分的资本支出:太空业务 $1.17b,连接业务 $1.37b,AI 业务 $15.83b,总计 $18.37b。SpaceX 于 2026 年 6 月 12 日上市,并于 2026 年 8 月 4 日提交了首份 10-Q,与业绩发布同日。↩︎

CNBC:SpaceX 今日股价、财报。营收 $7.81b,超出市场预期约 $1b,净亏损收窄至 $541m,而预期为 $1.9b,但资本支出 $18.37b,高于 $13.2b 的预期,且指引称将在未来两个季度维持这一水平。据 NPR 报道,自 6 月峰值以来,市值已蒸发超过 $1t。↩︎

截至 2026 年 6 月这一季度的公司业绩发布。各家的口径不同,此处不再重述:Amazon 采用其自身头条口径,即扣除销售与激励收益后的净额,对应 542 亿美元的采购总额;Meta 包含 9.62 亿美元的融资租赁本金偿付,这属于现金支出;Microsoft 采用其自身头条口径,包含融资租赁,且高于其现金流量表中 358 亿美元的物业与设备新增额,差额为非现金的使用权资产新增;Alphabet 采用现金流量表中的物业与设备采购额。Microsoft 的日历 Q2 即其 2026 财年 Q4。↩︎
-
从 2026 年 Q1 到 2026 年 Q2 季度资本开支的环比增长:Meta 113 亿美元,Amazon 99 亿美元,Alphabet 92 亿美元,Microsoft 91 亿美元,SpaceX 83 亿美元。若以完整的六个季度来衡量,各家的新增额出现分化,Amazon 新增 288 亿美元,而 SpaceX 为 156 亿美元,因此可比性仅适用于最近一个季度,而非整个期间。SpaceX 有两个季度是推算而非报告得出,并以空心点绘制:2025 年 Q2 由报告的 549% 同比增长反推得出,2026 年 Q1 由上半年总额减去 Q2 得出。2025 年其余季度无法推算,留空。↩︎

经营活动提供的净现金除以不动产及设备的购买总额,两者均取自现金流量表,这样对每家公司都保持现金口径。截至 2026 年 6 月 30 日的季度:Microsoft 为 $55.4b 对 $35.8b,Meta 为 $31.9b 对 $30.1b,Alphabet 为 $39.1b 对 $44.9b,Amazon 为 $45.4b 对 $54.2b。有三个期间不同:Oracle 是截至 2026 年 5 月 31 日的季度,由全年减去九个月推导得出,其 2027 财年第一季度尚未报告;CoreWeave 是截至 2026 年 3 月 31 日的季度,其 6 月季度尚未报告;SpaceXAI 是截至 2026 年 6 月 30 日的六个月,因为其首份 10-Q 不含季度现金流量表。现金资本支出低估了两家:CoreWeave 未计入 $4.6b 由 OEM 融资及应计的增项,若计入将使其降至 24%;SpaceXAI 未计入 $5.5b 的应计项以及 $3.9b 由其他融资方式提供的资金。↩︎

SPCX 每日收盘价来自 Nasdaq,经由 Yahoo Finance。IPO 于 2026 年 6 月 11 日定价为 $135,首个交易日收于 $160.95。最高收盘价为 6 月 16 日的 $211.39。第二季度业绩于 8 月 4 日收盘后公布,次日股价下跌 13.6%,从 $125.33 跌至 $108.27,而盘中报告的跌幅为 10%。↩︎

价格为 2026 年 8 月 5 日收盘价,以每 100 美元本金对应的美分计:2031 年到期、票面 5.350% 报 97.67,2033 年到期、票面 5.650% 报 96.49,2036 年到期、票面 5.875% 报 94.91,2046 年到期、票面 6.600% 报 91.16,2056 年到期、票面 6.650% 报 89.72。后四笔为 FINRA TRACE 成交记录;2031 年那一档没有 TRACE 报价,是法兰克福价格,属于不同的交易场所与交易时段。到期收益率从 2031 年那档的 5.86% 到 2056 年那档的 7.51% 不等。SpaceX 披露了票息与规模,但未披露发行价格,因此折价是相对面值衡量的;唯一一笔已披露的发行价,即 2056 年那档的 99.45,意味着相对发行价的亏损要小不到一个百分点。这 250 亿美元于 2026 年 6 月 23 日定价,认购订单接近 890 亿美元,并于 6 月 26 日交割。↩︎

Cursor:D 轮,2025 年 11 月 13 日,面向“数百万开发者”。SpaceX 于 2026 年 6 月 16 日同意以 600 亿美元股票收购 Anysphere,尚待监管批准。无论是 2026 年 5 月 20 日的 S-1 文件——其中描述了与 Cursor 的合作并披露了 Cursor 的资产负债表——还是 6 月 16 日的 8-K,都没有报告任何用户、席位或客户指标。全部以股票支付的对价依据私募发行豁免发行,因此不会再有 S-4 或委托书文件。↩︎

你的个人资本成本。据 CFO Bret Johnsen 在财报电话会议上透露,此次 IPO 筹集了约 857 亿美元的净收益,随后又发行了 250 亿美元的债券,使季度末的现金及有价证券达到 1000 亿美元。↩︎
SpaceXAI spent $18b of capex last quarter, $16b of it on AI.1 2
It’s a huge number. Amazon spent $53.1b last quarter, Alphabet $44.9b, Microsoft $41.0b, Meta $31.1b.3 SpaceXAI’s AI capex alone is nearly 40% of Microsoft’s total.
The slope of spending increase is comparable, too.4
The difference is who pays for it. Microsoft funds its buildout from operations with room to spare at 155% of capex, & Meta clears the bar by six points. Everyone else borrows or issues equity : Oracle 89%, Alphabet 87%, Amazon 84%, CoreWeave 39%, SpaceXAI 12%.5
Both sets of investors have marked the plan down. SPCX closed at $108 on 5 August, a fifth below the $135 IPO price & half the 16 June peak.6
Credit agrees, & the further out it lent the more it agrees. Every tranche of June’s $25b debut bond trades below par : the 2031s at 98 cents on the dollar, the 2056s at 90.7
SpaceXAI is pushing to compete : it has the data centers, it has trained a model in Grok 4.5 that ranks fourth on the Intelligence Index within six points of the leader,8 & it has millions of developers using Cursor.9
The IPO proved the company has a great cost of capital advantage.10
The question now is whether that advantage can sustain long enough for the AI business to reach parity with the others.

SpaceX Reports Second Quarter 2026 Results. Capex by segment : Space $1.17b, Connectivity $1.37b & AI $15.83b, for a total of $18.37b. SpaceX listed on 12 June 2026 & filed its first 10-Q on 4 August 2026, the same day as the results release. ↩︎
-
CNBC : SpaceX stock today, earnings. Revenue of $7.81b beat consensus by about $1b & the net loss narrowed to $541m against the $1.9b expected, but capex of $18.37b landed against a $13.2b estimate with guidance to hold that level two more quarters. More than $1t of market value has gone since the June peak, per NPR. ↩︎
-
Company results releases for the quarter ended June 2026. The conventions differ & are not restated here : Amazon is net of proceeds from sales and incentives, its own headline basis, against gross purchases of $54.2b; Meta includes $962m of principal payments on finance leases, which are cash; Microsoft is its own headline basis including finance leases & runs above the $35.8b of additions to property and equipment on its cash flow statement, the difference being non-cash right-of-use asset additions; Alphabet is purchases of property and equipment from the cash flow statement. Microsoft’s calendar Q2 is its fiscal Q4 2026. ↩︎
-
Sequential increase in quarterly capex from Q1 2026 to Q2 2026 : Meta $11.3b, Amazon $9.9b, Alphabet $9.2b, Microsoft $9.1b & SpaceX $8.3b. Measured across the full six quarters the additions diverge, with Amazon adding $28.8b against SpaceX’s $15.6b, so the comparability holds for the latest quarter rather than for the period. Two SpaceX quarters are derived rather than reported & are drawn as hollow points, Q2 2025 back-solved from the reported 549% year-over-year increase & Q1 2026 from the first-half total less Q2. The remaining 2025 quarters are not derivable & are left blank. ↩︎
-
Net cash provided by operating activities divided by gross purchases of property and equipment, both from the cash flow statement, which keeps the basis cash for every company. Quarter ended 30 June 2026 : Microsoft $55.4b over $35.8b, Meta $31.9b over $30.1b, Alphabet $39.1b over $44.9b & Amazon $45.4b over $54.2b. Three periods differ : Oracle is the quarter ended 31 May 2026, derived as the full year less nine months, with fiscal Q1 2027 not yet reported; CoreWeave the quarter ended 31 March 2026, its June quarter not yet reported; & SpaceXAI the six months ended 30 June 2026, since its first 10-Q carries no quarterly cash flow statement. Cash capex understates two : CoreWeave excludes $4.6b of OEM-financed & accrued additions, which would cut it to 24%, & SpaceXAI excludes $5.5b in accruals & $3.9b financed by other financings. ↩︎

SPCX daily closing prices from Nasdaq via Yahoo Finance. The IPO priced at $135 on 11 June 2026 & closed its first session at $160.95. The highest close was $211.39 on 16 June. Q2 results came after the close on 4 August & the shares fell 13.6% the next session, from $125.33 to $108.27, against the 10% reported intraday. ↩︎

Prices are the 5 August 2026 close, cents per $100 of principal : 5.350% due 2031 at 97.67, 5.650% due 2033 at 96.49, 5.875% due 2036 at 94.91, 6.600% due 2046 at 91.16 & 6.650% due 2056 at 89.72. The last four are FINRA TRACE prints; the 2031 tranche has no TRACE quote & is a Frankfurt price, a different venue & session. Yields to maturity run from 5.86% on the 2031s to 7.51% on the 2056s. SpaceX disclosed coupons & sizes but no issue prices, so the discounts are measured against par; the one reported issue price, 99.45 on the 2056s, means the loss against issue is a fraction of a point smaller. The $25b priced 23 June 2026 on nearly $89b of orders & settled 26 June. ↩︎

Artificial Analysis. Grok 4.5 shipped 8 July 2026 & scores 54 on the Intelligence Index against Fable 5 at 60, Opus 4.8 at 56 & GPT-5.5 at 55. The parity is closest on general reasoning & widest on coding, where Grok 4.5 records 64.7% on SWE-bench Pro against Claude Mythos 5 at 80.3%. Grok 4.5 is not ranked on LMArena’s main text board. ↩︎

Cursor : Series D, 13 November 2025, for “millions of developers.” SpaceX agreed to acquire Anysphere for $60b in stock on 16 June 2026, pending regulatory approval. Neither the 20 May 2026 S-1, which describes the Cursor collaboration & discloses Cursor’s balance sheet, nor the 16 June 8-K reports any user, seat or customer metric. The all-stock consideration was issued under a private-placement exemption, so no S-4 or proxy will follow. ↩︎
