What It Covers

Three business stories dominate: LEGO's record $13B revenue year driven by 860 new sets and distributed manufacturing; China's Nio completing 100 million battery swaps while growing 72% quarterly; and Nvidia CEO Jensen Huang's first blog post in six years mapping AI as a five-layer infrastructure stack worth trillions.

Key Questions Answered

• •LEGO's Dual Strategy: LEGO grew sales 16% — twice the toy industry average — by launching 860 new sets in one year (over two per day) while simultaneously building a seventh factory in Virginia. Localized production reduces tariff exposure, lowers shipping costs, and positions LEGO as a regional job creator, keeping it politically insulated from trade war pressures.
• •Nio Battery-as-a-Service Model: Nio operates 3,800 battery-swapping stations across China, completing swaps in 150 seconds for $25 — matching the speed and cost of a gas fill-up. Customers subscribe to batteries separately from the car, choosing battery size based on usage needs. This decouples the most expensive EV component from the purchase price entirely.
• •Nio vs. Tesla Growth Trajectory: Nio sold 125,000 EVs last quarter, growing 72% year-over-year, while Tesla recorded two consecutive years of declining sales. Nio's high-end models charge fully in five minutes — six times faster than comparable US EVs. Despite never posting a profitable full year and losing $2B annually, Chinese government subsidies sustain its aggressive expansion.
