AI's expansion is testing infrastructure, capital markets, and the way people work. Trump-backed World Liberty Financial is backing Hong Kong venture WorldClaw, which offers models from restricted Chinese companies; 43 of 90 come from entities flagged as security risks. Costs are mounting: 60 planned US data centers could emit 101.5M tons of CO2 annually, while Alphabet, Amazon, Meta, Microsoft and others carry roughly $3T in AI-related off-balance-sheet commitments. Data and software are shifting, too. Google agreed to pay $10M for Spirit Airlines' records, including about 100M emails and 500M Teams chats, while Slack launched Slack Code, project channels where teams collaborate with AI coding agents. Markets remain uneasy. SK Hynix announced a roughly $29B buyback, Unitree Robotics surged 460% in its Shanghai debut, and the 30-year Treasury yield hit 5.327%, a 19-year high as war and oil fears jolted markets.

Top 5 AI Highlights

[1] 💳 Stripe agreed to acquire AI model marketplace OpenRouter for $7.5B, with $1.5B going to the founders and $6B to investors, while it continues efforts to buy PayPal. OpenRouter has raised $164M and was last valued at $1.3B in May 2026. More from Bloomberg, Axios, and The New York Times.

[2] ⚡ Nvidia committed up to $105B to support SB Energy's Ohio data-center campus and invested $1.5B in the developer, while OpenAI signed a 20-year, 10GW lease backed in part by Nvidia. Together, the arrangements anchor Nvidia's $500B AI-infrastructure financing push, which follows July SEC guidance easing restrictions on data-center securitizations. More from Bloomberg, Wall Street Journal, and CNBC.

[3] 🤝 AI coding startup Poolside struck a non-exclusive $6B technology-licensing deal with Nvidia, which will also invest $1B at a $12B pre-money valuation; 109 Poolside employees received Nvidia job offers, while co-founders and co-CEOs Jason Warner, GitHub's former CTO, and Eiso Kant, a serial AI-software entrepreneur, will remain to run Poolside. More from Newcomer.

[4] 🏢 Anthropic-backed enterprise AI venture Ode acquired four-year-old consultancy Casper Studios for an undisclosed amount, expanding to more than 100 employees after its earlier purchase of Fractional. The acquisition comes as Anthropic's revenue run rate reached $65B by the end of July, up from $47B in May and $9B in late 2025. The company projects $190B-$200B in 2028 revenue and expects its IPO to raise at least $75B, matching or topping SpaceX's record-setting debut, as it prepares to file publicly as soon as the end of August. More from The Information, Bloomberg, and Reuters.

[5] 🏗️ Crusoe entered IPO talks with four Wall Street banks as JPMorgan advises on a $3B pre-IPO raise at a $35B valuation. Separately, Google secured warrants from Marvell to buy up to 59.0M shares, worth about $12.2B at the exercise price, under a custom-chip agreement tied to revenue milestones through fiscal 2033. More from Axios and Bloomberg.

✨Open Source AI Development

[1] 🧠 Last Friday, Alibaba released Qwen3.8-27B, an open-weight 27B model under Apache 2.0 with long context, vision, tool use, and coding. Qwen has 151,448 derivatives on Hugging Face, 2.6× Meta's total and 4.7× Llama specifically; Google has 82,506. Its GGUF files, a format optimized for local inference, draw 39.6M monthly downloads, versus Gemma's 20.8M and Llama's 7.5M. More from Qwen and Hugging Face.

[2] 🛡️ Z.ai debuted GLM-5.3 using the same base model as GLM-5.2, with scaled post-training producing a claimed 50% coding gain. Its cyber capability rose unexpectedly to 84.5% on CyberGym, ahead of Fable 5 and GPT-5.6 Sol, prompting a two-week delay before the weights are released for additional safety testing. More from Z.ai and Axios.

[3] ⚖️ Harvey's first proprietary legal model, Tenet, was built on the company's own adaptation of open-weight Kimi K3 and trained on mock disputes and case files, showing how open models can become domain-specific infrastructure rather than merely cheaper general-purpose alternatives. More from Business Insider.

[4] 📦 Google DeepMind says Gemma surpassed 1B cumulative downloads and inspired more than 100K community variants over the past two years. For context, Alibaba separately claims Qwen surpassed 3B global downloads during 2026 to date, though publisher-reported totals may use different counting methods. More from Google, Bloomberg, and Hugging Face.

[5] 🔀 Ramp launched Router, the AI model-routing service it has used internally for three years, in the US and will make it free through 2026. It offers models from OpenAI, Anthropic, DeepSeek, Moonshot, MiniMax, Nvidia, xAI, and Z.ai, plus strategies that route requests according to customer preferences. More from TechCrunch.
