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.

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

U.S. stocks traded mixed on midterm Election Day as investors de-risked ahead of the results: the Dow fell more than 200 points (about 0.5%) while the S&P 500 edged slightly higher and the Nasdaq gained about 0.8% in a tentative relief bounce after Monday's sharp intraday reversal. Apple extended its post-earnings slide, falling 4.5% in premarket trading after warning that rising memory-chip costs will pressure its holiday-quarter gross margin (45–46% guide); shares were set to open at their lowest since September 10. Nvidia climbed nearly 3% premarket, on pace to snap a four-day losing streak at its long-term 200-day moving average, and Microsoft gained nearly 2%. AMD rose 2.8% ahead of its quarterly report due after the bell. The 10-year Treasury yield rose to about 4.91–4.92%. Strategist playbooks: JPMorgan sees the S&P 500 falling about 0.5% Wednesday on a Democratic sweep; Wells Fargo sees a rally if Republicans retain both chambers; Morgan Stanley believes the correction that began in June is in its final stages.

What happened

Meta Platforms' $25 billion common-stock sale — the first tranche of its upsized $97.5 billion equity raise — ended about five times oversubscribed, according to Bloomberg-cited coverage, a strong demand signal for the largest equity raise of its kind. AMD confirmed a $1 billion pledge to the offering, joining Nvidia's previously announced $3 billion commitment; the two pledges answer the open question from earlier coverage about whether AMD and Broadcom would confirm participation and at what size. The sale's reception helped spark Tuesday's chip-led rally: the Nasdaq Composite rose 1.18% and the S&P 500 gained 0.60%, with AMD up 5.1%, Nvidia up about 1%, and Broadcom and Micron also advancing, even as Meta itself slipped about 1.5%.

What happened

Nvidia said late Monday / early Tuesday it will invest $3 billion in Meta Platforms' equity offering, as the two companies deepen their partnership on Meta's Muse AI assistant and related AI models. Meta will expand deployment of Nvidia infrastructure — including Vera Rubin and Vera CPUs and Nvidia networking — for next-generation AI agents, and the companies are considering further collaboration on agent-behavior monitoring (Nvidia's OpenShell/Sentry tools). Separately on Tuesday, Meta increased its largest-ever equity fundraising to $97.5 billion, upsizing the common-stock tranche announced Monday from $22.5 billion to $25 billion at $625 per share, alongside 250 million depositary shares at $50 each. Meta has launched about $35 billion in public offerings and plans a further up-to-$60 billion at-the-market program after its new non-voting Class C shares begin trading, expected in Q1 2027. Reuters reports the raise has drawn interest of up to $5 billion in total from Nvidia, AMD and Broadcom for Class A shares. Meta shares fell about 1.4% in morning trading Tuesday; Nvidia was roughly flat to modestly higher in premarket trading.

What happened

Dell expanded its Windows computing portfolio with new NVIDIA-powered systems developed with NVIDIA and Microsoft. The XPS 16 Creator Edition is Dell's first XPS laptop built around NVIDIA RTX Spark hardware, pairing a Blackwell GPU with a Grace CPU and up to 128GB of unified memory, with a 3.2K tandem OLED display; U.S. Best Buy pre-orders opened October 7. Dell also introduced the Creator Edition Desktop (up to one petaflop of FP4 compute, able to run up to 200-billion-parameter models, availability to follow soon) and renamed its Dell Pro Max workstation range to Dell Pro Precision, including GB300-based systems for Windows delivering up to 20 petaflops of FP4 and 748GB of coherent memory, capable of running up-to-1-trillion-parameter models locally. Shares rose 1.3% to $581.47 on the announcement.
