2026 智算基础设施

Executive Summary · English

(Data as of 2026-08-01) In late July, all four axes of AI compute infrastructure tightened at once. Moonshot AI released the full weights of its 2.8-trillion-parameter Kimi K3 on July 27, open-sourcing its training infrastructure and setting Hugging Face's fastest-growth record. Late-July earnings from Google, Microsoft and Amazon pushed combined 2026 Big Tech capex above $700 billion, with markets now pricing free-cash-flow discipline rather than growth alone. TSMC raised full-year capex to $60-64 billion with CoWoS still sold out, and reportedly launched an "EMIB-like" packaging route. SpaceX broke below its IPO price within a month of listing, SK Hynix sold off despite record results, and Anthropic's October IPO window approaches. The securitization of model companies and "power as the binding constraint" now define the second half. This refresh updates all data within the original value-chain framework.

• 01Moonshot AI released the full weights of the 2.8-trillion-parameter Kimi K3 on July 27 (modified MIT license), also open-sourcing its MoonEP/FlashKDA/AgentEnv training infrastructure; it topped Hugging Face trending within 30 minutes — the platform's fastest launch ever — and leads WebDev Arena at 1679 Elo, above Claude Fable 5 (1631) and GPT-5.6 Sol (1618), with Day-0 support from Huawei Ascend 950 and Alibaba Cloud. Giant open-weight models are spilling inference demand across the industry.
• 02Late-July earnings confirmed demand: Alphabet's Q2 capex hit $44.9B (roughly doubling YoY) with full-year guidance raised to $195-205B; Microsoft spent $41B in the quarter (+70%) as Azure passed $100B in annual revenue and the stock jumped 8%; Amazon lifted 2026 capex to ~$220B; Meta's Q2 free cash flow reportedly fell to $784M. Combined Big Tech outlays exceed $700B this year (Reuters), and markets now price free-cash-flow discipline.
• 03TSMC's July 16 Q2: revenue $40.2B (+36% YoY in NT$), net income +77.4% — a fifth straight record quarter; full-year USD revenue growth guidance raised above 40% and capex lifted from $52-56B to $60-64B; CoWoS remains sold out with 52-78 week lead times; on July 30 TSMC reportedly launched an 'EMIB-like' packaging route, sending its ADRs up over 7%. Advanced packaging is still the binding constraint.
• 04The power bottleneck hardened: Musk-affiliated entities reportedly acquired mobile-power firm APR Energy for up to ~$1B (Axios); SpaceX (which absorbed xAI in February) said on July 31 that Memphis Colossus runs on 69 unpermitted gas turbines to be removed by July 2027 as it transitions to a permanent 1.2GW captive gas plant, with $2.8B of further turbine purchases disclosed in its IPO filing; the House Energy Committee demanded records by August 11.
• 05Model-company securitization entered a stress test: SpaceX raised $75B on June 12 in the largest US IPO ever, then broke below its $135 issue price in mid-July, shedding over $1.2 trillion from peak value (reported); SK Hynix listed on Nasdaq July 10 and its July 29 Q2 (operating profit KRW 60.54T, +550% YoY) still missed estimates, sinking the stock; Anthropic ($965B valuation after its May round) began investor meetings July 15 targeting an October listing, while OpenAI reportedly slips to 2027.
• 06China primary market and applications refreshed: Moonshot reportedly plans a final pre-IPO round in August targeting a $50B pre-money valuation (current round at $31.5B pre-money, per NBD); Zhipu (HK-listed since January) completed a ~HK$31.4B placement on July 13; SoftBank became Sierra's exclusive Japan partner on July 14 (LINEMO resolution rate lifted to 97%); Apple sued OpenAI on July 10 over trade secrets, which OpenAI denies — application rollout and big-tech clashes are heating up in parallel.
