This week's field notes across AI & Product, Building, Money, Well-being, and the merely fascinating. Stuff I stumbled upon this week.

⚡ 20 Second Snippets

💸 A global AI/chip sell-off rattled markets last week, even as IBM's stock surged on a chip breakthrough, but markets bounced back.
🧩 Claude Skills are the upgrade most people haven't switched on. See how to start.
🎬 Sony's betting $100M on domed “shared reality” theaters.
🏃 Your phone's camera can read your heart rate, no wearable needed.
🔭 The X Games just rebooted as a team league, kicked off in Sacramento over the weekend.

Artificial Intelligence & Product

🧩 Start using Claude Skills to level-up

Claude Skills are the upgrade most people haven't switched on yet. A Skill is a repeatable workflow you teach Claude once: your format, your steps, your rules. From then on it runs on command instead of you re-explaining it every time. Think “turn these notes into our status update,” “clean and chart this CSV”, etc.

Why it's worth it: it turns Claude from a chat partner into something closer to a trained teammate. You stop repeating yourself, the output stays consistent, and a boring 20-minute job shrinks to one sentence. Building one takes about five minutes: name it, tell Claude when to use it, and paste in your instructions.

New to this? Start with Anthropic's plain-English explainer, What are Skills, then build your first one with the hands-on Skills cookbook.

Also in AI & Product:

🌶️ OpenAI built its own chip: Jalapeño, its first custom inference chip with Broadcom, went from design to fab-ready in about nine months and beat current silicon on performance-per-watt. It's a direct strike at the one job (inference) Nvidia owns, and part of OpenAI's full-stack push. TheStreet
🏁 The race to own AI: a16z's Robert Hackett on why the demand to own a piece of AI (SPVs, secondaries, pre-IPO futures, synthetic shares) is routing around every barrier. He frames it as the “read, write, own” era breaking loose. a16z crypto
🇪🇺 Europe's wake-up call: “Europe 2031,” a speculative essay on how Europe lost the AI race, says the bloc (just ~5% of global compute) should have built “like a country at war”: Special Compute Zones that cut data-center permitting from two years to three months, plus a coalition of middle powers pooling their leverage. Europe 2031
📉 ChatGPT slipped below 50%: its global share fell to 46.4% as Gemini (27.7%) and Claude (10.3%) gained, though Claude leads on paid conversion. TechCrunch
🧠 The PM is the new bottleneck: as AI makes ideas cheap, judging them well becomes the real job. Lenny's Newsletter

Building Cool Stuff

🎬 A “shared reality” dome for immersive worlds

Sony is putting $100M into Cosm, the company building domed “shared reality” theaters that drop you inside immersive worlds. Picture The Matrix or Harry Potter wrapped around a giant dome. It's a bet on owning the full-stack venue: the screen, the show, and the night out. The category is heating up, with smart-venue deals hitting ~$199M in 2026. Variety

Also in Building:

🚀 The one-person company is having a moment: far more solopreneurs now clear $1M+ than a few years ago. Stripe's economists peg it near a million of these “nanocorps,” now that AI lets one person do what used to take a team. Stripe economists
🤑 The $2M/yr quiz site nobody brags about: Bryce Welker passed the CPA, then built sites that help others pass it (CPA, LSAT and more). Boring niche, captive demand, a ~$126B test-prep market. Venture Radar
🤖 Scaling a consumer app: the operator behind Cal AI (No. 1 in Health & Fitness in 18 months) says distribution is the #1 bottleneck. Four people ran hundreds of influencer deals with a system. Jake Castillo on X

Money & Markets

💸 The AI trade is back

After last week’s AI-fueled rout, the market flipped. The same tech giants that led the sell-off powered the bounce-back, pulling stocks higher as fears over AI’s payoff cooled. The real story is the whiplash: this trade now swings hard both ways, and Big Tech is still the market’s center of gravity. Financial Post

Also in Money & Markets:

🔬 IBM stock is surging: shares jumped ~6% after IBM unveiled the world's first sub-1nm chip, a 7-angstrom “nanostack” design. It was the third bullish catalyst in days (alongside a JPMorgan upgrade to a $291 target), and the chip promises up to 50% more performance or 70% better efficiency than 2nm, potentially extending Moore's Law another decade. TheStreet
🪙 Tokenized real-world assets topped $51B in market cap, up 40% YTD even as crypto fell ~20%. The fight over how to tokenize equities is on. The Block (citing Bernstein)
🤖 Morgan Stanley doubled its China humanoid-robot forecast: it now sees 50,000 units shipping in 2026 (up from 28,000), a $2B market heading to $15B by 2030, citing state-backed demand and faster commercial rollouts. CNBC
🦾 Wall Street's first humanoid-robot stock: Agility Robotics is going public via a $2.5B SPAC, with $300M+ in Digit pre-orders and a $1T market in its sights. TechCrunch
🎲 Meta is building a prediction-markets app (“Arena”): points-based for now, real money not ruled out, as Zuckerberg chases the next social behavior. NPR

Well-being

🏃 Your phone is becoming a health sensor

Google researchers showed a phone's front camera can passively read your heart rate by detecting tiny changes in facial blood flow, no watch or ring required. As health data gets abundant, the win is meeting people where they already are: on their screens. Fitt Insider

Also in Well-being:

🏋️ MetCon, explained: why metabolic conditioning (think CrossFit / HIIT) is less a workout than a framework for training your energy systems. Levels
🌱 The mindset note: “Wanting the result is easy. The misery starts when you want it without wanting the ordinary, unglamorous days it's actually built from.” That's Jay Yang, in And then what?

Curiosities

🔭 The World Cup got a data brain

At World Cup 2026, FIFA rolled out data-driven Power Rankings (powered by Aramco): every outfield player gets a 0–10 score for attacking, creativity, and defending, and keepers for possession and shot-stopping, with a live top-100 per category. FIFA
