The Manufactured Wealth of the Shanghai Silicon Valley
Paper billionaires are currently being minted faster than working 5nm transistors in Shanghai. The recent public debut of Moore Threads on the STAR Market on December 5, 2025, sent shockwaves through the exchange, with shares surging over 400 percent on day one. To the uncritical eye, this looks like a triumph for Chinese self-reliance. To a financial auditor, it looks like a high-stakes shell game. Despite the 1.1 billion dollar IPO, Moore Threads is bleeding cash, posting 1.5 billion yuan in net losses for the previous fiscal year. The market is pricing in a geopolitical miracle that the current yield data simply does not support.
Retail enthusiasm is bordering on the delusional. The retail portion of the Moore Threads IPO was over 2,700 times oversubscribed, driven by a nationalistic fervor to find a domestic alternative to Nvidia (NVDA). However, the technical reality is far grimmer. While founder Zhang Jianzhong, an ex-Nvidia executive, touts a similar architecture, the company’s AI accelerators are reportedly struggling with software compatibility and power efficiency compared to the Blackwell series. The “catch” is that these companies are surviving on a life-support system of state subsidies from the 344 billion yuan Big Fund Phase III, not market demand or operational profit.
The Pay to Play Tax and the H200 Conundrum
On December 8, 2025, the landscape for Western chipmakers shifted from a blockade to a shakedown. The US Department of Commerce announced a “pay-to-play” scheme allowing Nvidia and AMD to sell high-end AI chips like the H200 to China, provided they surrender a 25 percent revenue stake to the US Treasury. This move, framed as a pragmatic compromise, is a poison pill for margins. For Nvidia, which once relied on China for 25 percent of its revenue, this is a choice between losing the market entirely or operating as a tax-collection agent for the federal government.
The skepticism among institutional investors is palpable. Over the last five trading sessions leading into December 17, Broadcom (AVGO) has plummeted 21 percent. The market is finally waking up to the fact that the AI infrastructure buildout is facing a wall of diminishing returns. Oracle (ORCL) also saw a 5 percent drop this morning after reports surfaced that Blue Owl Capital would not back a critical 10 billion dollar data center project. The capital is drying up just as the costs of staying in the race are reaching astronomical levels.
SMIC and the Yield Wall
While Semiconductor Manufacturing International Corp (0981.HK) stock has seen a technical buy signal this week on heavy volume, the underlying fundamentals are a house of cards. Beijing has quietly mandated a 50 percent domestic equipment rule for all new capacity additions. This is a desperate attempt to force adoption of unproven local lithography tools from companies like Naura and AMEC. The result? Yield rates for 7nm and the rumored 5nm Kirin 9100 are estimated to be below 30 percent.
For context, a modern fab requires yields above 80 percent to be commercially viable. SMIC is not making money on these chips; they are being paid by the state to fail until they succeed. The upcoming Huawei Mate 80 series, rumored for a spring release, will likely serve as a marketing showcase rather than a profit driver. The technical disparity between Chinese domestic silicon and the 2nm mass production just announced by TSMC in Taiwan is widening, not narrowing.

| Moore Threads | +400.0% | NEGATIVE | Unprofitable Onshore IPO Bubble |
The Fragile Detente of Pax Silica
The current market stability is a mirage built on a fragile trade detente. While President Trump dangles the H200 carrot, the bipartisan “Safe Chips” bill in the Senate is gathering momentum, seeking to block all advanced exports to China for 30 months. This internal US friction creates a dangerous environment for investors who are betting on long-term supply chain predictability. The Netherlands has also officially joined the US-led push to further restrict DUV and EUV tool maintenance in China as of this morning, effectively capping SMIC’s growth at current levels.
Investors must look past the 400 percent IPO gains and the technical buy signals. The real story is the massive capital expenditure required to maintain a sub-par domestic supply chain that is decoupled from global standards. The Chinese chipmakers are not rising through innovation; they are rising through a state-funded defiance of economic gravity. When the subsidies eventually rotate or the yield failures become too expensive to hide, the correction will be brutal for anyone holding the bag.
The critical data point to watch is the January 15, 2026, Bureau of Industry and Security (BIS) review of the H200 export licenses. If the US decides to revoke the conditional approval or increase the revenue stake beyond 25 percent, the current rally in Hong Kong and Shanghai will evaporate overnight. Watch the yield reports for the Kirin 9100. If the defect density does not drop by the Lunar New Year, the Mate 80 launch will be a paper launch for a paper billionaire era.
