Key Discussion Points & Insights
1. OpenAI Pilots ChatGPT Group Chats
- OpenAI is running a pilot for group chats in ChatGPT across Japan, New Zealand, South Korea, and Taiwan.

- The feature is rolling out to free, plus, and team users, both on web and mobile.
- Group management:
- Chats are invitation-only; members can leave at any time.
- Most group members have the ability to remove others; only the creator can voluntarily leave.
- Under-18 users get additional safeguards and parental controls.
- Functionality:
- Tap the people icon to start/add via link.
- New group is created if you add someone to an existing one.
- Profiles, sidebar organization, and image-based personalization supported.

2. Amazon and Anthropic Join Microsoft Against Nvidia in US AI Chip Wars
- Amazon and Anthropic join Microsoft in backing the GAIN AI Act, which would prioritize US buyers for advanced AI chips—potentially limiting Nvidia's exports to China.
- Rare corporate split: Microsoft and Amazon, usually Nvidia's major customers, now oppose Nvidia in public policy.
- Policy implications:
- Chipmakers must fill domestic demand before exporting to countries with arms embargoes.
- Exemptions for “trusted” tech firms to speed up export processes to places like the Middle East.
- Political landscape:
- The act has support from key Democrats but still requires Senate and House Republican buy-in.
- Meta and Google remain on the sidelines; Trump administration hasn’t taken a stance.
- Nvidia lobbying up sharply—$3.5 million this year versus $640,000 in 2020.
- “Right now, that tension is getting more complicated.” —Ray Wang, Futurum Group [06:50]
- **Legislation would benefit hyperscalers’ access to AI chips, possibly shifting market dynamics.
3. The OpenAI–Elon Musk–Apple Legal Showdown Rolls On
- A US judge has refused to toss a lawsuit from Musk’s X and xAI accusing Apple and OpenAI of colluding to suppress competition in AI.
- Key allegations: Apple’s integration of OpenAI in iPhones allegedly limits innovation and consumer choice.
- Responses:
- OpenAI: Claims Musk is waging “lawfare” amid his feud with Sam Altman.
- Apple: Denies exclusive dealings, pledges to work with other AI partners.
- “Pittman didn’t explain his decision... but directed both parties to submit further filings.” [09:45]
4. Cursor’s Explosive AI Startup Growth
- Cursor raises 10x valuation in 2025 and now boasts over $1 billion in annualized revenue, plus a workforce of 300.
- In-house models generate more code than nearly any other LLM.
- Jensen Huang, Nvidia CEO, calls Cursor his “favorite enterprise AI service.”
- “Our immed is on building out the company and growing the team and we have a lot more to do before thinking about anything like going public.” —Michael Truell, Cursor CEO [11:05]
- Cursor joins a rarefied club (alongside OpenAI, Anthropic, xAI, Safe Superintelligence, Thinking Machines) valued at $10 billion+.
- Not rushing to IPO; focus remains on product and team expansion.
- Competitive context: Anthropic’s Claude Code saw $500 million ARR in just a few months; Windsurf, another competitor, reports $82 million ARR (July 2025).
5. Google Sues Global SMS Phishing Kingpins ("Lighthouse" Network)
- Google identifies and sues 25 individuals (by Telegram handles where necessary) for running a massive SMS phishing ring dubbed “Lighthouse,” allegedly netting up to $1 billion over three years.
- The scam: Fake texts about UPS deliveries, Toll road payments, etc., trick users into giving credentials on spoofed sites.
- Nearly 200 templates mimic USPS, NYC government, Google, and payment/social media sites.
- Google's countermeasures:
- Files suit under RICO, Lanham, and Computer Fraud and Abuse Acts.
- Admits criminal leaders may be beyond US jurisdiction (group believed China-based), but aims to disrupt infrastructure.
- Pledges support for new bipartisan anti-fraud, anti-robocall legislation.
- "Legal action can address a single operation. Robust public policy can address the broader threat of scams... We encourage Congress to enact these crucial bills." —Halima Delaine Prado, Google General Counsel [13:30]
6. Weekend Long Read Recommendations
- Bloomberg: Sundar Pichai’s quiet turnaround of Google post-ChatGPT emergence.
- “Google is the strongest performer in the so-called Magnificent 7 stocks this year, beating even Nvidia. The credit for that lies with the man at the top.” [14:35]
- Vanity Fair: The meme coin (crypto) gold rush—massive fortunes, minimal intellectual rigor.
- "Being stupid actually was good. The dumber you are, the more money you make." —Alex Taub [15:10]
- CNET: AI parental anxiety—no longer only about privacy, but about deepfakes and AI identity theft for kids.
- Bonus: Tease for a “portfolio profile” episode about ex-Apple engineers’ AI startup, focused on modernizing and securing COBOL/mainframe systems, plus insider tips to win a Y Combinator spot.
