ChinaBiz Briefing | Baidu's AI Pivot, SHEIN's Hong Kong Debut, SMIC Record Margins

China's technology and capital markets converged on a single theme on August 28: the infrastructure of artificial intelligence is being repriced, refinanced, and rebuilt at a pace that legacy valuation frameworks cannot adequately capture. From Baidu's structural listing conversion to SHEIN's supply-chain-as-a-service IPO, from SMIC's record margin guidance to XPeng's autonomous driving architecture overhaul, the day's news collectively signals that China's AI investment cycle has moved beyond the experimental phase — and that the market is still catching up.

Baidu Crosses the 50% AI Revenue Threshold — and Rewrites Its Own Valuation Story

Baidu announced it will convert its Hong Kong secondary listing to a dual-primary listing effective September 1, with no new shares issued and no capital raised. The timing is deliberate: AI-driven revenue has now accounted for 50% of core business income for two consecutive quarters, with Q2 2026 core revenue reaching RMB 25.2 billion. GPU cloud revenue surged 283% year-on-year. Shares jumped more than 6% intraday on the announcement.

The listing conversion unlocks potential Stock Connect southbound eligibility — possibly as early as the week of September 7 — opening Baidu's Hong Kong shares to mainland investors. That matters because mainland investors are more likely to apply a sum-of-the-parts framework to Baidu's six distinct businesses: Kunlun Chip (independently valued at up to US$50 billion by Morningstar), Intelligent Cloud, Apollo Go, AI applications, search advertising, and a net cash position of US$39.3 billion. A bullish SOTP analysis aggregates to approximately US$129 billion — more than four times Baidu's current market capitalization of roughly HK$248 billion. The dual-primary listing is Baidu's formal argument that a decade-old search-advertising P/E multiple no longer fits.

Citi: Nvidia's H200 China Sales Are a Footnote, Not the Capex Story

Nvidia disclosed on its August 26 earnings call that it sold a small volume of H200 chips to Chinese customers under U.S. government licenses — the first such AI chip sales to China since early 2025. Citi Research estimates the revenue at under US$890 million, or less than 1% of Nvidia's quarterly data center sales.

That figure is statistically irrelevant against the combined AI capex wave from China's three largest internet companies: Alibaba (RMB 67.7 billion, up 75% year-on-year), Tencent (RMB 52.8 billion, up 176%), and Baidu (RMB 11.4 billion, up 201%) — all in Q2 2026 alone. Citi interprets the spike as partly a procurement timing anomaly and forecasts a sequential Q3 decline, while projecting full-year 2026 capex of RMB 207 billion for Alibaba and RMB 200.7 billion for Tencent. The more consequential unanswered question: where exactly are hundreds of billions of renminbi going? Domestic GPU suppliers and memory chip vendors are the most likely beneficiaries — none of the companies have said so explicitly.

MiniMax Triples Its Alibaba Cloud Spending Cap to $1.2 Billion

Chinese AI startup MiniMax has raised its three-year cloud procurement ceiling with Alibaba Cloud from $375 million to $1.2 billion — a 220% increase — after consuming 65.7% of its original full-year limit in just the first half of 2026. Annual caps now scale from $300 million in 2026 to $500 million in 2028. Separately, MiniMax's API supply arrangement with Alibaba was expanded nearly nineteenfold to $62.5 million over three years.

The deal illustrates a structural dynamic reshaping China's AI industry: as frontier model developers scale training and inference workloads, hyperscale cloud providers with large GPU clusters are becoming indispensable — and increasingly captive — infrastructure partners. MiniMax plans to deploy approximately $1.621 billion, roughly 80% of recent fundraising proceeds, into AI infrastructure by end-2027. Alibaba holds an indirect 11.36% stake in MiniMax, classifying the arrangement as a connected-party transaction under HKEX rules and requiring independent shareholder approval.

Bilibili's Profit Surges 55% as Advertising Displaces Gaming at the Top

Bilibili reported Q2 2026 net profit of RMB 339 million, up 55% year-on-year, with adjusted net profit rising 25% to RMB 704 million — its eighth consecutive quarter of adjusted profitability. Total revenue reached RMB 7.94 billion, up 8%. Advertising revenue grew 28% to RMB 3.13 billion, becoming the platform's largest segment for the first time. Mobile gaming revenue fell 14%, the only declining segment.

The advertising streak — 14 consecutive quarters of 20%-plus growth — is exceptional against a broadly pressured Chinese digital ad market. AI-related ad revenue more than doubled as hardware and software vendors targeted Bilibili's technically literate user base. Gross margin reached 37.2%, the 16th consecutive quarter of year-on-year improvement. With operating profit expanding at roughly six times the pace of revenue, Bilibili is no longer a loss-narrowing story — it is compounding earnings. The critical near-term risk: whether a breakout gaming title emerges in H2 2026 to reverse the segment's decline.

SMIC's Profit Jumps 94% — Record Margin Guidance Signals a Genuine Inflection

China's largest contract chipmaker reported H1 2026 net profit of RMB 44.67 billion, up 94.2% year-on-year, and guided Q3 gross margins to a record 26%–28% — a threshold never previously breached. Operating cash flow surged 252% to RMB 207.6 billion. Management confirmed it is now negotiating price increases in supply-constrained product categories, a qualitative shift from prior cycles. Mainland China accounted for 89.6% of revenue, up from 84.2% a year earlier.

SMIC is capturing AI infrastructure demand not at the leading edge — EUV equipment bans preclude sub-7nm competition — but in the ecosystem of mature-node chips surrounding AI servers: power management ICs, display drivers, image sensors, and analog components. The structural tension remains unchanged: annual capex has risen from US$4.1 billion in 2021 to US$8.4 billion in 2025, the company has paid zero dividends since its 2020 STAR Market listing, and ROE sits at approximately 3.2%. SMIC is less a conventional equity investment than a leveraged call option on China's semiconductor self-sufficiency agenda.

SHEIN Prices at 13x Earnings in Hong Kong — a 53% Discount to Inditex

SHEIN launched its HKEX global offering on August 24, with institutional bookbuilding reaching full subscription and the retail tranche closing oversubscribed on August 27. Trading begins September 1. The offering is expected to raise HK$13.12 billion (approximately US$1.68 billion) at a market capitalization of roughly US$26 billion — 13x trailing earnings, versus 28x for Inditex and 21x for H&M, despite superior gross margins (67.9%), faster inventory turns (36 days versus Zara's 71), and US$14.8 billion in cash.

The valuation discount prices in regulatory risk — U.S. and EU scrutiny over import duty structures and data privacy — not operational deterioration. The more consequential long-term story is SHEIN's services revenue, which grew 446% in two years to US$4.74 billion, reaching 14.3% of total revenue in Q1 2026 and running at roughly twice the group operating margin. The model — opening SHEIN's supply-chain and fulfillment infrastructure to third-party brands via the SHEIN Xcelerator platform — mirrors cloud computing's infrastructure-as-a-service playbook. Cornerstone investors including Tencent, Hillhouse, and General Atlantic have accepted a six-month lock-up, signaling conviction at the IPO price.

XPeng's New VLA Model Adds Time as a Native Dimension — and Clears Robotaxi Testing

XPeng unveiled its second-generation VLA (Vision-Language-Action) autonomous driving model on August 27 in Guangzhou, incorporating temporal reasoning as a native architectural feature. The system retains a 30-second visual memory buffer and projects forward six seconds via a world prediction model — enabling anticipatory behavior in ambiguous urban scenarios that static "see-then-act" architectures cannot replicate. The same day, XPeng's GX-based Robotaxi fleet received Guangzhou municipal approval for driverless road testing without a front-seat safety driver.

The technical and regulatory milestones together advance XPeng's pivot from EV maker to physical AI platform — a transition formalized by its Q1 2026 rebrand to "XPeng Group." The second-generation VLA's parameter count is 3.5 times its predecessor; a Mixture-of-Transformers architecture manages the compute load within onboard chip constraints. Training data throughput has increased tenfold in six months, drawing on a fleet of approximately one million vehicles. XPeng now competes directly with Baidu Apollo and Pony.ai in driverless Robotaxi operations — with the same AI stack extending to its Iron humanoid robot via the Turing chip, giving the architecture cross-platform optionality that neither rival currently matches.

What to Watch Next

The week of September 7 is the critical near-term inflection point: if SMIC's Q3 margin guidance holds and Baidu clears the Stock Connect review cycle on schedule, two of China's most significant AI infrastructure repricing theses will face their first live market tests simultaneously. SHEIN's September 1 trading debut will provide the first real signal of whether Hong Kong's equity market is prepared to price a supply-chain platform at a premium to a fast-fashion retailer. And as China's hyperscaler capex normalizes sequentially in Q3, the identity of the domestic GPU and memory chip suppliers absorbing that spending will become the most consequential disclosure gap in the sector.
