Key points
- Moonshot AI stopped taking new Kimi subscriptions about 48 hours after K3 launched. Its GPUs are near capacity limits.
- The Philadelphia Semiconductor Index starts the week 20% below its June record, a bear market by the standard definition.
- Brent crude closed at $88.10, up 4.6% Friday, as US-Iran fighting around the Strait of Hormuz escalated.
- Alphabet (GOOGL) and Tesla (TSLA) report Wednesday, Intel (INTC) and Nokia (NOK) Thursday. The Kospi reopens Monday after a 6.4% crash and a holiday.
On Friday we argued that Kimi K3, the Chinese model that set off last week's chip selloff, would end up proving the bulls right on compute demand. Cheap models multiply usage. Usage burns GPUs. We did not expect the proof to arrive before Monday's open.
Over the weekend, Moonshot AI stopped taking new Kimi subscriptions. Demand for K3 pushed its GPUs close to their capacity limits within roughly 48 hours of launch. That news lands at the start of a week that also includes escalating fighting around the Strait of Hormuz, oil at $88, the Kospi's first trading session since Thursday's crash, and one of the heaviest earnings calendars of the quarter. Here is what we are watching.
The model that "killed" chip demand just ran out of chips
Moonshot's announcement was about as direct as these things get. K3 has received "far more love than we expected, and our GPUs are feeling it," the company posted on X. To protect service for existing subscribers, it is temporarily pausing new signups. It says it is adding compute capacity as fast as it can, will reopen subscription slots in batches, and plans to split its membership into a standard tier and a separate Kimi Code tier for coding workloads, so it can ration GPUs more precisely.
Sit with that for a moment. The release that dragged the Philadelphia Semiconductor Index deeper into a bear market did so on the theory that cheap, efficient models mean the world needs less compute. The company that built the model could not keep up with demand for two full days.
One honest caveat. Moonshot largely cannot buy Nvidia's (NVDA) top chips under US export controls, so its capacity scramble is not a direct order for American silicon. But the argument that hit chip stocks last week was never about one vendor. It was about the direction of total compute demand. On that question, a sold-out model is about the clearest answer you can get.
The tape this lands on
Last week was ugly. The S&P 500 lost 1.6% and the Nasdaq fell 2.9%, with chips doing most of the damage. The semiconductor index ended Friday 20% below its June record, and July alone has erased roughly a third of its 2026 gains. Memory stocks fell hardest, with Sandisk losing 29% on the week.
Friday itself showed how fragile sentiment is. Chip stocks slid at the open, snapped back hard by midmorning, and still finished lower. Nvidia closed down 2.3% at $202.64. Alphabet (GOOGL) lost 2.2% to $346.62 and Tesla (TSLA) gave up 2.6% to $380.84. Nothing about that price action says the selling is finished. It says the market is waiting for a reason to pick a direction, and this week supplies several.
Oil at $88 and a war that is getting worse, not better
The other weight on this market is not about AI at all. The ceasefire between the US and Iran has effectively collapsed, and the fighting around the Strait of Hormuz escalated through the week. US strikes have expanded beyond the strait into northern Iran, and on Friday hit bridges and power stations in the south. And Kuwait said Iran attacked a power and water desalination plant on its territory, which is what sent crude higher into the weekend.
Brent rose 4.6% Friday to close at $88.10, and WTI settled at $82.49. President Donald Trump has said he is reinstating a blockade on tankers carrying Iranian oil through the strait. Roughly a fifth of the world's oil moves through that waterway, which is why every headline out of the region now moves the energy complex within minutes.
The earnings calendar gives us a direct read on both sides of this. Oilfield services firms Halliburton (HAL) and SLB report Tuesday and Friday. Defense names Northrop Grumman (NOC), Lockheed Martin (LMT) and RTX report Tuesday and Thursday, with an active shooting war as the backdrop for their guidance.
Korea reopens tonight with two days of news to digest
The Kospi has not traded since Thursday, when it crashed 6.4% to 6,820.60. Friday was Constitution Day, a newly reinstated market holiday in Seoul. So Monday's session, which opens Sunday evening US time, is Korea's first chance to price in both Friday's Wall Street selloff and the weekend Kimi capacity news.
The setup is stranger than a simple catch-up trade. While Seoul was closed, US-listed shares of SK Hynix kept trading, and Americans were paying about 25% more than the Seoul price for the same company. Either that premium compresses or the Korean shares gap up toward it. Watch the close in Seoul more than the open. Korea's leveraged ETF complex has been mechanically selling into weak closes, and that pressure does not care what the morning headlines say. Samsung Electronics and SK Hynix together are still the market's center of gravity, so where they finish Monday will tell US traders plenty before Wall Street even opens.
The earnings gauntlet
Monday and Tuesday are the warm-up. General Motors (GM), Northrop, 3M (MMM) and Charles Schwab (SCHW) headline Tuesday morning, with Capital One (COF) after the close. The real weight arrives midweek.
Wednesday after the close is the pivot point for the whole week. Alphabet reports with analysts expecting $2.87 in EPS, and two numbers will matter far more than the earnings line: Google Cloud growth and capital spending. Cloud is the cleanest read on real AI demand this market gets. Last quarter, it grew 63% to just over $20 billion in revenue, and its backlog of signed contracts swelled past $460 billion. Chief executive Sundar Pichai told analysts Alphabet was "compute constrained" and would have booked even more cloud revenue if it had the capacity to sell. Sound familiar? That is the same problem Moonshot just admitted to, at a vastly larger scale. If Wednesday's numbers show cloud growth holding anywhere near that pace while capacity stays tight, the cheap-AI panic loses its central argument. On the spending side, Alphabet has already guided 2026 capital expenditures to as much as $190 billion, part of big tech's roughly $725 billion AI data center year, and this report is the first chance since the Kimi selloff for a hyperscaler to either confirm that trajectory or blink. Tesla reports the same evening, with estimates at $0.44. So do Texas Instruments (TXN), whose analog chips make it the best read on real-economy demand outside of AI, and ServiceNow (NOW). IBM also reports Wednesday, filling in the full quarter behind the July 14 preannouncement that produced the worst single-day drop in its history. That morning brings AT&T (T) and GE Vernova (GEV), which gained 2% Friday while nearly everything else fell. The AI power trade is still where nervous money hides.
Thursday belongs to the chip and telecom names. Intel (INTC) reports after the close with a thin $0.19 estimate, and the stock enters the week at $95.03 after a brutal July. Nokia (NOK) reports before the open, with estimates at $0.07. Chief executive Justin Hotard, who ran Intel's data center and AI group before taking over last year, has been steering the company toward AI data center networking, and that segment grew 49% last quarter. Its commentary doubles as another demand data point. STMicroelectronics (STM) and SAP report the same day, along with T-Mobile (TMUS), Honeywell (HON), Union Pacific (UNP) and Blackstone (BX). Friday closes out with Verizon (VZ), American Express (AXP) and SLB.
What we are watching
Four things, in order. Does Google Cloud keep growing 60%-plus while Alphabet's capex guidance holds or grows after a week of cheap-AI panic. Does the Kospi close strong or fade into its final hour again. Does Brent hold above $85, which keeps the inflation question alive right as a fifth of the market reports. And does anyone on an earnings call actually say demand is slowing, because so far the only company anywhere in the AI supply chain reporting a demand problem is the one that had too much of it.
None of this tells you where the week ends. It tells you where the pressure is. A bear market in chips, a war premium in oil, and a sold-out AI model make for an uncomfortable mix, but uncomfortable weeks are usually the ones that resolve the argument.
