US-China AI Primary Market Capital Flows: H1 2026

Per PitchBook, US venture funding reached $412.7B in H1 2026, nearly 30% above all of 2025, with $355.9B (86%) flowing to AI — 86 cents of every venture dollar. On Crunchbase's count, global venture hit $510B in the half, surpassing 2025's full-year $440B and setting a record for any half-year period, with over 70% going to AI. Concentration is the cycle's defining feature: OpenAI ($122B) and Anthropic ($95.6B) together absorbed 43% of global venture funding, making H1 effectively a two-company market. Late July's marginal change: concentration is not reverting but spilling down the model-compute-energy-channel chain, while new funding talks at DeepSeek and Moonshot push the 'narrative premium' higher still. For primary-market investors, headline totals now matter less than structure — at 86% sector concentration, conventional portfolio diversification logic is breaking down, which frames the analysis in the sections that follow.

OpenAI raised $122B in H1 at an $852B post-money valuation, led by Amazon ($50B committed in February) with Nvidia and SoftBank at $30B each. The IPO cadence shifted: per multiple late-June reports, management leans toward delaying the listing to 2027 — CFO Sarah Friar favors later, citing cash burn, compute commitments and public-reporting burdens, while Altman reportedly refuses to list early below a trillion-dollar price. Anthropic is ahead: it filed a confidential S-1 on June 1, targeting Nasdaq as early as October with Goldman Sachs, JPMorgan and Morgan Stanley underwriting a raise of over $60B; its Series H private valuation is $965B, secondary markets imply $1.05-1.15T, annualized revenue was about $30B as of April, and on July 27 it expanded its enterprise partnership with Cognizant. Regulation entered release cadence for the first time: GPT-5.6 (the Sol/Terra/Luna lineup) rolled out in stages under the pre-release review created by the June 2 executive order, opening broadly only on July 9 — Washington effectively deciding when frontier models reach the public. On hardware, Apple sued OpenAI on July 10 over trade secrets (see the risk section's layered treatment), yet OpenAI still shipped the $230 Codex Micro coding device on July 15.

China's keyword is shifting from 'valuation leap' to 'delivery verification.' DeepSeek closed its first external round of roughly RMB 50B (~$7B) in late May at about $52B post-money; founder Liang Wenfeng personally invested RMB 20B (40% of the round) as the largest single backer, followed by Tencent (RMB 10B), the CATL ecosystem (RMB 5B), and JD/NetEase/IDG (RMB 3B each). On July 15, multiple outlets reported talks with new investors at roughly $71-74B (figures vary), with an IPO anchored to 2027 and possibly earlier. The harder event: DeepSeek V4 went GA on July 20 — a 1.6T-parameter MoE with 1M-token context across the lineup, plus first-of-its-kind peak/off-peak API pricing. Moonshot opened its round at $31.5B pre-money and closed it in late July at $35B post-money with $3.5B raised; with June ARR around $300M, the valuation implies over 100x ARR — crystallizing the 'narrative premium' debate; it reportedly plans a pre-IPO round at up to $50B and may list in Hong Kong this year. Zhipu completed a ~HK$31.4B H-share placement on July 9 (HK$1,588/share, the year's largest single tech placement in Hong Kong), and on July 11 Tang Jie's internal letter launched the 'Touch High' plan. WAIC closed in Shanghai on July 20 with the launch of the World AI Cooperation Organization, the first intergovernmental AI body, headquartered in Shanghai; separately, roughly two-thirds of the world's new robotics unicorns in 2026 are reportedly Chinese.
