Star 50 index up 29% in 2026 as China's AI trade hits 150x earnings

China's AI boom has a second front, and it's in Shanghai's STAR Market. The Financial Times is flagging a benchmark that keeps outrunning its US counterpart — and now trades at a multiple that makes the Nasdaq 100 look cheap.

Shanghai's tech-focused Star 50 index is up 29% in 2026 and trades at a price-to-earnings ratio above 150 — more than four times the Nasdaq 100's roughly 35 — the Financial Times reports. The rally is fueled by Beijing's push to make AI and advanced manufacturing the economy's center of gravity, plus an investor frenzy that has turned China's chip and optical-module names into the country's version of the Magnificent Seven. The index is effectively a listed proxy for China's AI infrastructure complex: semiconductors make up roughly a third of its weight, and communications equipment — the optical-transceiver makers feeding data-center buildouts — another third, per an analysis from Baiguan.

The valuation picture is what makes the FT's numbers worth sitting with. Zhongtai Securities chief economist Li Xunlei warned earlier this month that the STAR 50's median P/E had already approached 100; the index-level multiple has since pushed past 150. That is A-share "ceiling valuation" in action — investors pricing the most optimistic version of the AI future today, rather than waiting for earnings to arrive. And this has not been a straight line: the combined STAR & ChiNext 50 basket rose about 138% from early 2025 to June 2026, then crashed 25.9% in July — its worst month on record — in the same global AI selloff that hit US markets. August has brought a sharp rebound, with computing-power hardware surging again. We covered the fallout on this side of the Pacific — Jane Street takes $15B July hit after Situational Awareness meltdown.

Why it matters: the China AI trade is now the other half of the global bubble debate. US investors worry about concentration in a handful of megacaps; China's rally is narrower and hotter, carried by hardware suppliers with real revenue but valuations that assume flawless execution. Beijing is signaling it will keep the floor propped — the July politburo meeting pledged to bolster market resilience and investor confidence, and this week's frontier-tech push has money piling back in. The precedent to remember is 2021's new-energy peak: even companies that delivered their promised profits watched the ceiling crack once the narrative wobbled. When price runs ahead of earnings, delivery alone doesn't save the trade.

What to watch: whether Beijing's support can hold the floor if the August rebound stalls.

At 150x earnings, is China's AI trade pricing in perfection — or is the US the one that's cheap? Tell us in the comments.

Brain organoids classified Braille at 83% — in a trio, not alone

Two stories today: human brain tissue on a chip decoded a tactile signal, and the data-centre company behind some of the largest AI contracts in Europe turns out to be six months behind on its flagship site. Human forebrain organoids grown on a microelectrode array classified Braille letters with 61 percent accuracy on their own and 83 percent when the responses of three organoids were combined, in a peer-reviewed study from the University of Bristol. The team took event-based tactile readings

Suleyman says Microsoft's base model beat OpenAI's on a quarter compute

Microsoft finished pre-training its biggest in-house model yet — then used it to make a point about the company it bankrolls. Microsoft AI completed pre-training of MAI-Base-2, a mixture-of-experts foundation model with 80 billion active and 2.8 trillion total parameters, and says the recipe is 4.2–12.3x more pre-training FLOPs-efficient than DeepSeek-V4-Pro-Base. The run itself is the number worth keeping: 16,000 Nvidia GB200 GPUs for 38 days across August and September, at 21% average model

Amazon's new Bee devices listen all day — for $11.99 a month

Amazon turned its always-listening Bee line into a two-device family on Thursday, and NVIDIA opened a 2.8-trillion-token Indic corpus recipe. The connecting thread: both are bets that the next AI money is in memory — yours, or your model's. Amazon put two new always-listening devices on sale, and both now lead to a subscription. Bee Frontier, the next-generation wristband that also clips to clothing, ships now at $74.99 in Onyx, Lavender and Sage — up from the $50 predecessor — with seven-day

Perplexity open-sources its agent sandbox after 118 failed escapes

Perplexity handed its agent containment layer to the open-source world, and Washington's AI task force stopped reading briefings and started working. Perplexity open-sourced SPACE on Thursday — the sandbox it built to keep its own AI agents from getting out — and says nine frontier models failed to break out of it across 118 attempts. Each agent runs inside a small virtual machine with its own operating system, with credentials and network access managed outside the sandbox so an agent can re
