The AI Trade Is Already Splitting — Two Days Before Trump and Xi Sit Down

Reuters reported today that with two days to go before the Sep 24 Trump–Xi meeting in Washington, capital on both sides of the Pacific is positioning for outcomes rather than waiting for them. The article frames investors as deliberately playing both tracks: US banks have been bookrunners on 19 Chinese high-tech equity deals worth $17.2B so far this year — nearly a third of the sector's total issuance — while Chinese outbound mutual funds now run roughly $150B of assets, with US stocks making up nearly half of the book. US equity held by Hong Kong residents and mainland Chinese crossed $750B, up 23% in a year.

That positioning matters because the Bessent–He Lifeng talks that wrapped in New York on Sep 20 did not deliver what NVIDIA bulls were hoping for. Eight hours of negotiation produced a \"very successful\" label and a brand-new US-China AI dialogue with a notification system for serious AI incidents, plus a Board of Trade to work on tariffs — but US Trade Representative Jamieson Greer explicitly said chip and equipment export controls were not part of the mechanism. For the H200 pipeline, that is no movement at all.

NVIDIA's Aug 26 quarterly release is the anchor for the bull-bear split. Q3 revenue guidance of $108.0B ±2% explicitly assumes no Data Center compute revenue from China. That is the floor; any chip deal that actually ships chips is incremental upside that the guide does not capture. The reported Q2 of $96.2B (+106% YoY, Data Center $89.0B) shows what demand looks like without China — the company is still growing faster than any other in the S&P 500 — and the $5.5T market cap reflects the premium investors pay for that trajectory.

The reason chip controls were kept off the table in New York is the leverage on the other side. Per AlixPartners data cited by Reuters, China controls up to 70% of global rare-earth mining, 85% of refining capacity, and roughly 90% of rare-earth alloy and magnet production — and those magnets go directly into the precision robotics, defense electronics, EV drivetrains, and chip manufacturing equipment that the US is trying to onshore. When Beijing restricted seven rare earths and the permanent magnets made from them last year, the licensing bottleneck that followed was the catalyst for the original Busan truce in October 2025.

That constraint is what makes the 25% US revenue cut on H200 sales politically durable. It monetizes chip exports for the Treasury without crossing Beijing's red lines, but China has responded by simply not issuing its own approvals. May 2026 Reuters reporting showed that despite ~10 H200 licenses being cleared by Washington, not a single H200 had been delivered — and a Barron's piece published this week noted Chinese authorities have allowed ByteDance and Tencent to receive only around 10,000 H200s each, well under the 75,000-unit cap.

The summit's impact cascades in both directions through a tightly mapped supply chain. On the upstream side, Taiwan Semiconductor (market cap ~$2.3T) sits as the foundry choke point — its August 2026 monthly revenue of NT$514.8B was up 53.3% YoY, with Jan-Aug 2026 revenue +39.3% YoY. ASML (market cap ~$659B) remains the only producer of EUV lithography machines China cannot domestically replace, with TTM revenue of $35.3B and a 52.5% gross margin. In memory, SK Hynix and Samsung Electronics are the HBM stack that feeds NVIDIA's accelerators.

On the downstream side sit the Chinese hyperscalers that are licensed to buy but cannot receive: Alibaba, Tencent, ByteDance (private), and JD.com. Both Alibaba (P/E 25.6x on $1.04T TTM revenue) and Tencent (P/E 14.7x) trade at a fraction of Microsoft's 27.9x and Alphabet's 17.8x — a structural discount that has historically been pinned to geopolitical risk and that could compress sharply if the chip valve reopens. Baidu, the smallest and most exposed to the China-cloud-only story, trades at negative earnings and a market cap of $31.4B; it has the most binary upside if compute access improves.

The pattern says the market is not waiting for Sep 24 to reveal winners. The Sep 20 New York talks delivered enough on AI safety (a formalized dialogue, a notification system, a Shenzhen follow-up in two months) to allow risk-on positioning across both Microsoft and Alibaba. The Sep 24 main event is now about whether Trump and Xi use the leverage they each have — chip revenue on one side, rare-earths and approval gates on the other — to push the needle further than the staff-level groundwork.

Three dates shape the trade. Sep 24 is the summit itself — any H200 delivery commitment, any change to the 25% revenue cut, or any rare-earths deal moves NVIDIA and the chip-supply chain first. The two-month Shenzhen AI dialogue follow-up, announced today, is the next milestone for content-control or model-evaluation rules; that hits Microsoft and Alphabet (whose TPU/Cloud positions depend on where the frontier-model guardrails land). And NVIDIA's late-November Q3 FY27 print is the moment the street sees whether $108B was the floor or the ceiling.
