Market-moving news for Monday, November 9, 2026

What happened

Nvidia, Korean AI-chip startup Rebellions and SK Telecom announced a collaboration on Monday, November 9, at Nvidia AI Day Seoul 2026 to advance Korea's sovereign AI infrastructure. Rebellions will connect its next-generation Rebel R200 neural processing units to Nvidia's platform through NVLink Fusion and build rack-scale inference systems on Nvidia's MGX rack architecture; SK Telecom plans to deploy those systems in its AI data centers, linking them to its proprietary A.X K2 foundation model and public-facing services under Korea's government-backed 'AI for All' project. The effort is supported by Korea's Ministry of Science and ICT, which is also expanding broader cooperation with Nvidia covering AI semiconductors, data-center infrastructure, models, agents, talent development and security, including work with Samsung, Kakao Mobility, LG Electronics and Hyundai Motor Group. The partners plan disaggregated inference — Nvidia GPUs for prefill, Rebellions NPUs for decode — to improve throughput and power efficiency. R200 systems are expected to be ready for deployment in 2028; no performance specs, volumes, prices or financial terms were disclosed.

What happened

Google announced two new TPU systems on Monday, November 9, completing its eighth-generation lineup at four systems in a single year — a first in more than a decade of TPU development. TPU 8tx is built for secure and confidential inference (plus small-scale training) for regulated enterprises and governments: it uses the same silicon as the training-focused TPU 8t, pairs it with 5th Generation AMD EPYC host CPUs and the low-latency Boardfly network, building encryption into the hardware layer so data and model weights stay protected even while in active use, with up to 2x lower latency than TPU 8t. TPU 8i Max targets the memory wall for massive context windows: it combines two TPU 8i chips in a single package, doubling the compute, on-chip SRAM and HBM bandwidth of TPU 8i and delivering the highest compute density per rack. Google also opened up TPU development to PyTorch developers, launched its TPU agent suite and XLA Serving Engine, and said shipments of the two new systems are expected next year.

Microsoft is winding down a 2023 arrangement to rent AI computing capacity from Oracle, Bloomberg reported on Friday, November 6, citing people familiar with the matter. Microsoft decided not to renew the contract and has spent recent months switching off the rented capacity, which was originally used to power the AI-assisted version of Bing, because the Oracle servers run an older generation of Nvidia chips that no longer meet Microsoft's evolving needs. The full size of the deal was never disclosed and could not be determined. Oracle responded that demand for its AI infrastructure remains strong, including for earlier-generation GPUs, saying GPU capacity that came up for renewal in its fiscal first quarter was renewed or resold at about a 20% premium to prior long-term pricing. Bloomberg framed the move as part of a wider Microsoft reassessment of the more than $80 billion it has committed to renting capacity from outside cloud providers, including CoreWeave, Nscale and Nebius.

What happened

Google has taken over Crusoe's unfinished data-center project in southeastern Wyoming, Crusoe confirmed on Friday, November 6. Google, which Crusoe had tried and failed to land as a customer for the project, is taking over development after reportedly raising concerns about its cost and construction timeline under Crusoe's management. A day earlier, Google announced plans to invest $17 billion to develop the campus, its first data center in Wyoming, powered mainly by a planned 702 MW fuel-cell plant built with Bloom Energy units and contracted through American Electric Power, alongside grid power, gas generation and carbon capture. Neither company disclosed what Google paid Crusoe for the site. Crusoe is still developing another Google data-center campus near Amarillo, Texas.

What happened

President Donald Trump told CNN on Sunday, November 8, that it is 'highly unlikely' he will need to order the US back to war with Iran as long as there is progress in negotiations over Tehran's nuclear program and reopening the Strait of Hormuz, repeating the assertion five times during a 20-minute phone interview with CNN's Jim Sciutto. 'It depends on whether or not they sign a very strong agreement,' Trump said. 'The answer is highly unlikely it's going to be necessary.' He added that he was 'not looking to' escalate the war in a separate CBS '60 Minutes' appearance. At the same time, Trump stressed the military option remains on the table, saying three US aircraft carriers are in the region, 'fully locked and loaded,' and that the US has identified 38 bridges and other infrastructure targets inside Iran it could destroy 'in literally one hour.' He also claimed Iran's air defenses have been destroyed and that Tehran retains only about 10% of its missile capacity and 15% of its drone capabilities.

What happened

Taiwan's government moved over the weekend to arrest the rout in its stock market, and the measures took effect on Monday, November 9. The Financial Supervisory Commission cut the cap on intraday short-sale orders for borrowed shares to 3% of a stock's 30-day average daily volume, down from 30%, and raised the minimum margin for short sales to 130% from 90%, while encouraging buybacks. At an emergency meeting on Friday afternoon, the National Financial Stabilization Fund authorized its tenth-ever market-rescue operation, putting NT$500 billion (about $15 billion) on standby to buy stocks. The Taiex surged as much as 6.7% intraday and stood up 5.79% at 42,001.22 in midday trading, its biggest one-day gain since July 31, ending a seven-session losing streak; TSMC gained about 4.7%, MediaTek more than 4% and Foxconn about 6.5%. South Korea acted in parallel, suspending the margin-loan collateral rule that forces brokers to liquidate leveraged retail accounts; SK Hynix gained about 4.6% and Samsung about 2.4%. Nasdaq 100 futures, down about 0.8% at Sunday's open on the Nvidia probe news, recovered to roughly flat by Monday morning.

What happened

China's State Council Tariff Commission announced on Monday, November 9, 2026 that it will maintain the suspension of an additional 24% tariff on US imports for two more months, effective 13:01 on Tuesday, November 10, while retaining a 10% additional tariff. The move was announced by China's finance ministry on its website and reported by Reuters at 02:48 UTC. The extension implements the consensus reached by Presidents Xi Jinping and Donald Trump at their September summit in Washington. Beijing also said it will closely monitor potential US moves to replace tariffs imposed under the International Emergency Economic Powers Act (IEEPA) — which courts have held invalid — with Section 301 tariffs, and adjust its retaliatory measures as appropriate.
