a16z's AI infrastructure team has successfully backed two acquisitions within five days: Cursor has been acquired by SpaceX, and Stripe announced the acquisition of OpenRouter. According to The Information, the total value of a16z's holdings corresponding to these two investments has exceeded $8 billion.In 2024, a16z participated in Cursor's $60 million Series A round, when the company's valuation was only $400 million. Now, SpaceX is acquiring Cursor for $60 billion. Bloomberg previously reported that a16z is Cursor's largest external shareholder, holding about 10%, which is valued at approximately $6 billion based on the acquisition price.In 2024, a16z established its first $1.25 billion infrastructure-focused fund. The Information states that the two transactions involving Cursor and OpenRouter are enough for the related fund to return all principal to LPs and also provide additional profits. This year, a16z raised another $1.7 billion for its infrastructure fund and recently raised an additional $1.1 billion specifically for AI hardware. Martin Casado, head of AI infrastructure, noted that a few years ago, only about 5% of the startup projects he encountered were in hardware, and now that figure is close to 20%.

According to the latest data from OpenRouter reported by the Daily Economic News, the total global invocation of AI large models last week (from August 31 to September 6) reached 115 trillion tokens, a month-on-month increase of 1.77%. Among them, the weekly invocation of China's AI large models reached 56.72 trillion tokens, a month-on-month increase of 2.83%, surpassing the United States (16.54 trillion tokens, a month-on-month decrease of 3.1%) for nineteen consecutive weeks, ranking first in the world.Among the top five global invocation volumes, four are Chinese models. Tencent's Hyper Yuan Hy4 preview ranks first with 14.7 trillion tokens, a month-on-month increase of 379%; GPT-5.6 Luna ranks second with 12.9 trillion tokens; Zhiyu GLM-5.3 Flash rises to third with 12.4 trillion tokens; DeepSeek-V4-Flash's official and preview versions rank fourth and fifth, respectively.MiniMax M3 returns to the list after nearly a month, ranking sixth, and has become the foundational base for Saudi HUMAIN's Arabic large model. In addition, Xiaomi MiMo-V2.5 and Gemini 3.7 Flash fell out of the list this week.

Research institution Delphi Digital stated that hardware limitations are driving Chinese laboratories to shift towards cheaper models and more efficient technology stacks. Export control restrictions limit their access to advanced chips, while domestic accelerators can handle inference, but cutting-edge training remains difficult to achieve. Chinese laboratories are innovating in system efficiency, model architecture, training data, and reinforcement learning. DeepSeek has found a way to avoid GPU idle data movement, and ByteDance and Moonshot are set to release similar versions within months.In terms of architecture, training is shifting to cheaper digital formats that are compatible with domestic chips. Sparse architectures reduce the runtime per token, and the attention mechanism has been redesigned three times to control the memory costs of long context. In terms of data, denser prediction targets and better optimizers enhance the learning signal per token. In reinforcement learning, DeepSeek's GRPO has become the default recipe, with ByteDance, Alibaba, and MiniMax each launching successor plans within a year. Chinese models are now among the lowest-cost cutting-edge adjacent systems.On OpenRouter, the proportion of token consumption by Chinese developed models is expected to rise from less than 1.2% at the end of 2024 to the majority by 2026. The Chinese AI market is experiencing a price war from 2024 to early 2026, with several laboratories implying revenue multiples of about 47-117 times, while Anthropic and OpenAI are around 15-21 times. Huawei's Ascend chips are currently available for inference, and DeepSeek reportedly attempted to train R2 on Ascend but returned to NVIDIA after encountering technical issues. Domestic accelerator supply remains below estimated demand.

According to Axios, payment giant Stripe stated in a letter to investors that January 1 marks "the beginning of a singularity," viewing it as a significant turning point in a long-term trend, and believes that maintaining a private structure is best suited for this critical moment, with the IPO likely to remain on hold. The company reported a 41% year-on-year revenue growth in the first half of the year and a 43% increase in free cash flow; 88% of the companies in Forbes AI 50 (including OpenAI and Anthropic) are building on its platform, with revenue from AI and crypto companies more than doubling year-on-year.Stripe also confirmed the acquisition of the AI routing platform OpenRouter, with the transaction amount not publicly disclosed; Axios learned that the amount exceeds $8 billion and is primarily paid in stock. Stripe stated that remaining private helps advance mergers and acquisitions and long-term investments without diluting shareholders, with its equity count now lower than three years ago, and a compound annual return of about 31% since the D round. The company stated that the total payment volume on its platform is expected to reach $1.9 trillion by 2025, a year-on-year growth of 34%; in February this year, the employee stock purchase valuation was approximately $159 billion. There are also reports that Stripe is in discussions with Advent International to acquire PayPal for about $53 billion.

According to Business Insider, Stripe is in talks to acquire the AI model marketplace startup OpenRouter for over $8 billion.If the deal goes through, the more than 17% stake held by Andreessen Horowitz (a16z) will be worth nearly $1.5 billion, while it initially invested about $20 million; Menlo Ventures holds over 6% of the stake, having invested less than $50 million, and its current value has exceeded $500 million. The total return for the two institutions is close to $2 billion.
