Markets that swung this week:
AI & compute
Moonshot published Kimi K3's weights on the evening of July 26, a day ahead of its own deadline: 2.8 trillion parameters across 96 shards, about 1.4 terabytes, under a modified MIT license, the largest open release to date. Anthropic responded July 27 with a position paper saying it has never advocated a ban on open weights. OpenAI cut GPT-5.6 Luna's price 80 percent on July 30, and DeepSeek shipped V4-Flash-0731 on July 31 at an unchanged 14 cents per million input tokens. The threatened US restriction on Chinese open models has still not appeared.
OpenAI cut its cheapest model's price 80 percent on July 30, four days after Kimi K3's weights appeared.
On GitHub this week, trending is mostly packaging knowledge as agent skills: books become skills, codebases get reverse-engineered into them, and code review goes open: virgiliojr94/book-to-skill · zhaoxuya520/reverse-skill · alibaba/open-code-review · 1jehuang/jcode
Signals to watch
Undercurrent
Science reported this week that the leading AI startups publish almost none of their research, a sharp break from the field's open norms of a decade ago. Then OpenAI illustrated the new mode on August 1: ten claimed advances in mathematics and theoretical computer science, credited to an internal model called Astra that no one outside can use, shipped with Lean proof certificates instead of peer review. Greg Brockman put the compute cost near $2,000 at API rates. The proofs are checkable; the system that produced them is not.
Deep-dive of the week
Memory-chip maker CXMT opened its Shanghai debut on July 27 up 472 percent from its IPO price, briefly China's most valuable listed company. The financial layer underneath is deleveraging: Shanghai margin traders cut leveraged positions about 14 percent over July, brokerage data show. Two ChinaTalk essays this week mapped the structural edges. One argues China's real bottleneck is zombie firms that subsidies keep alive. The other warns the West is fixated on who owns mines while China builds the automation that runs them: 72 percent of battery-powered autonomous haul trucks operate in China.
Clearing zombie-firm inefficiency would add 0.7 to 1.2 points of annual growth, IMF work cited by ChinaTalk estimates, roughly a fifth of China's target.
Geopolitics
Mediators from Egypt, Qatar, Turkiye and the US announced late on July 30 that Hamas has agreed to disarm in stages against a phased Israeli withdrawal, with a detailed roadmap due within 14 days. Israel has not publicly signed on, and one Israeli minister called the deal unacceptable. The same week, thousands crossed from Morocco into Ceuta and Spain deployed the military, Ukraine's drones burned Wildberries warehouses in its costliest strike on Russian commercial infrastructure, and the Danube fell so low that Hungary's only nuclear plant stopped generating for the first time in 44 years.
Gaza Board of Peace announces Hamas disarmament agreement: what we know
Staged disarmament against staged withdrawal, with heavy weapons on a 200-to-350-day clock; the first structured end-of-war framework either side has accepted.
Ukrainian drones kill 8 in Russia and strike Wildberries warehouse
The weekend wave on Russia's biggest online retailer killed eight; Russian analysts put cumulative damage near 100 billion rubles, the war's costliest campaign against commercial infrastructure.
Spain deploys military to Ceuta after migrant surge: what we know
Thousands crossed from Morocco in days and at least 18 died; France tightened its borders in response, and the free-movement argument moved to the EU's center.
Dry Danube threatens nuclear power in Romania and Hungary
Hungary's Paks plant, source of about half the country's power, stopped generating August 2 for the first time in 44 years; river-cooled reactors met a river that is no longer there.
Second phase of Kashmir elections concludes amid rigging allegations
PML-N swept eight of ten declared refugee seats in the August 2 vote after a summer of unrest that killed more than 30; landslides pushed several constituencies to August 4.
Japan earthquake death toll rises to 18 as rescue efforts continue
The July 28 Kumamoto quake killed at least 18. TSMC's Japanese fab reported no structural damage and resumed operations; Tokyo Electron halted plants while the chip supply chain checked itself.
The disarmament agreement gives mediators 14 days from July 31, to about August 14, to produce the detailed roadmap.
Commodities & energy · 2026-07-31
Brent gave back 6.9 percent to $90.12 and WTI 5.2 percent to $84.67 as Saudi Arabia floated a naval coalition to protect Gulf shipping, word spread that US-Iran talks would restart, and OPEC+ headed into Sunday's meeting expected to add supply. It did: 188,000 barrels a day for September, completing the rollback of the 2023 cuts. Grains broke too, corn, wheat and soybeans all down 5 to 6 percent, and natural gas fell 4.3. Coffee, the one riser, snapped a monthlong slide with a 5.8 percent gain. The forward question is whether $90 crude holds once the Iran talks actually convene.
| Brent crude | $90.12 | -6.9% |
| WTI crude | $84.67 | -5.2% |
| Soybeans | 1172.00 | -6.1% |
| Wheat | 639.25 | -5.7% |
| Corn | 440.75 | -5.1% |
| Natural gas | $2.75 | -4.3% |
| Coffee | 332.10 | +5.8% |
Markets
The Federal Reserve held rates at 3.5 to 3.75 percent on July 29, with three regional presidents dissenting for a quarter-point increase, the most same-direction dissents since 2016. Chair Warsh called it a family fight and kept the statement short. Kalshi's September contract ended the week pricing a hike as more likely than a hold. Equities recovered anyway on a split earnings week: Microsoft and Amazon jumped about 9 percent on their reports, Meta fell about 10 on a miss with capital spending raised again. The S&P 500 rose 1.05 percent to 7,489.72 and the VIX fell to 16. The Bank of Japan held at 1 percent with the yen near a 40-year low. Directional only, not investment advice.
| Trend | UP |
| Volatility | Calm (16.0) |
| Yield curve | Steep (+106 bp) |
| Growth (GDPNow) | 5.0% |
| Dollar | Down (99.8) |
| Crypto | RISK-OFF |
Volatility measures how much the market is expected to move in the near term compared with the longer term, so a lower reading means less immediate stress. The yield curve is the gap between long-term and short-term government borrowing rates, and a steep curve usually points to expected growth rather than recession. When crypto is described as risk-off, investors are stepping back from the most speculative assets, which often serves as an early note of caution beneath a calm market.
The wildcard · Football's capital revolt
On July 30, UEFA's 55 national associations voted unanimously to boycott all FIFA competitions, the World Cup included, over President Gianni Infantino's plan to sell stakes of up to 20 percent in FIFA's commercial enterprise to private investors, Joshua Kushner among them. The statement demanded the plan be abandoned entirely, with binding assurances it would never return. FIFA withdrew the proposal within two days, and by August 1 UEFA had declared the matter closed. A fight that could have split world football ended as the fastest institutional climbdown of the year.
short items from the week’s edges
World Cup fans bet billions through prediction markets (Bellingcat, July 30)
Prediction platforms have become de facto sportsbooks for the World Cup, taking billions in wagers outside gambling regulation.
FTC and two states sue Hims & Hers over health-data sharing (FTC, July 29)
The complaint says the telehealth firm sent customers' medical conditions to Meta and Snap for ad targeting while marketing itself as privacy-focused.
The China backlash, quantified (NBER, week of July 27)
Geyiktepe and Rodrik find presidential sentiment on China has declined since the early 2000s, and that presidents followed Congress and the media rather than leading them.
How to stop China from freeriding on American AI (War on the Rocks, July 29)
The restrictionist case for distillation controls, published the same week the open-weights flood arrived.
Regime radar · read through markets and hard data
The slow currents beneath the week. Each is read from a basket of dated markets and hard data, not a single headline.
AI sovereignty and open weights opening
Last week's test resolved. The biggest open release to date actually landed, on time and a day early, and Washington let it: the restriction weighed in July had produced no order or rule by August 2, and the most restriction-minded US lab published a position paper disclaiming any wish for a ban. The live question moves from whether the flood is real to whether distillation controls and safety-testing mandates, the asks Anthropic substituted for a ban, get traction in the fall.
Energy as the inflation swing factor easing
The two-week, 27 percent oil spike unwound in five sessions: Brent settled at $90.12, down 6.9 percent, on a Saudi naval-coalition proposal, a reported restart of US-Iran talks, and OPEC+ supply. But the rates pressure the spike created did not unwind with it. Three Fed dissents and a September hike market above 50 percent show the committee now arguing about an economy running hot on its own, and the Danube shutdowns point at the grid's next constraint: cooling water.
Holding steady
Global monetary tightening tightening. Yield curve (10y-3m): +106 bp (steep).
China's industrial stack advancing. CXMT Shanghai debut (July 27 open): +472% vs IPO price.
Trade fragmentation tightening. Section 301 duties: 10-12.5% on ~60 economies; no retaliation through Aug 2.
The calendar ahead
August 12 July consumer-price report
The first full month of tiered Section 301 duties, with the oil spike and its unwind both inside the survey window.
About August 14 Gaza disarmament roadmap deadline
Mediators have 14 days from July 31 to produce the detailed plan; Israel has still not publicly accepted the framework.
Mid-August US-Iran talks and the memorandum window
Talks were announced to resume August 3. The June memorandum's sixty-day window nominally runs out mid-month; crude at $90 is priced for progress.
Late August Nvidia reports
The last big AI-capex datapoint of the summer, after a week in which Meta was punished for raising spending and Microsoft and Amazon were rewarded for it.
September 16 Federal Reserve meeting
Kalshi's market ended the week with a quarter-point hike priced above a hold, after three dissents in July.
September 28 CFIUS deadline on the Electronic Arts buyout
The EU's foreign-subsidies review closed July 30 without a probe; the US national-security review is the last gate on the $55 billion deal.
