Nvidia’s revenue from China (%)

Hey there!

Welcome back to The Pulse, where we dive into interesting AI stories and trends backed by data, all presented through simple visuals.

> China share 13% (~$17B 2024) → 0% in 2025

> AI-GPU market share from ~95% → 0% after USA bans (A100 → H100 → A800/H800 → H20)

> ~1M H20 sold in 2024; no shipments in 2025 so far + $5.5B write-down on unsellable China chips

> ~$1B in banned Nvidia GPUs reportedly smuggled into China

> Trump-era deal: Nvidia must pay 15% of China sales for export licenses

> Beijing ordered firms to limit Nvidia purchases → H20 production suspended

> China also opened an antitrust probe into Nvidia’s Mellanox deal, escalating tensions

> Beijing tightened export rules on gallium, germanium, antimony, graphite, etc. - metals essential for AI chips and semiconductors

> new rules require case-by-case export approval for any product using Chinese-sourced material (even outside China)

> gives China a kill switch over global data-center growth, semiconductor supply & military

> move retaliates against U.S. chip bans; markets wiped $2T on Trump’s response before rebounding next day

> prices for gallium and germanium spiked 20–40% post-controls

> China refines ~98% gallium, 70–80% antimony, ~99% graphite - full control of usable output

> building refining elsewhere takes years; short-term dependency locked

> first practical & verifiable quantum advantage; repeatable and confirmed by experiment

> 99.9% operation accuracy, errors dropped as chip size scaled up

> 105-qubit Willow chip ran a verifiable algorithm 13,000× faster than current IBM’s frontier supercomputer

> “Quantum Echoes” revealed atomic-scale interactions unseen in classical models

> foundation for quantum-assisted drug discovery and materials design

> published in Nature, independently reproduced - a first in quantum research
