President Trump said Sunday he agreed to cancel a large-scale strike on Iran after Tehran and other Middle Eastern governments requested time to finalize what he called the "perimeters of a deal" — including the full reopening of the Strait of Hormuz and an end to Iran's nuclear threat, with Israel joining the commitment, according to Al Jazeera and Bloomberg. Trump made clear the cancellation is conditional on the deal actually closing quickly, and reportedly spoke with Saudi Crown Prince Mohammed bin Salman on Saturday, who cautioned against a massive strike. It's the most concrete de-escalation signal since the war widened sharply a week ago — the single biggest swing factor for the region's risk premium heading into a new week, if it holds.

The Kospi surged as much as 17.9% Friday to close at a record high, its biggest single-day percentage and point gain ever and well past the 11.95% record set during the 2008 financial crisis, with Samsung Electronics up roughly 28% and SK Hynix up roughly 30% as the same AI-chip relief that hit Tokyo swept through Seoul even harder, according to Korea JoongAng Daily. For Tokyo, it's the clearest confirmation yet that this week's memory-sector selloff was a positioning unwind rather than a demand-cycle break.

Microsoft's stock surged roughly 15.5% Thursday, adding about $450 billion in market value in one session, after Azure's annual revenue crossed $100 billion for the first time and posted 43% growth — its fastest pace since early 2022, according to Yahoo Finance and Axios. The move topped Nvidia's own previous record one-day gain, and it's the same AI-infrastructure enthusiasm that helped light up both Tokyo's chip-equipment complex and the Kospi on Friday.

Leopold Aschenbrenner's Situational Awareness fund, run by the former OpenAI researcher whose leaked internal memo made him famous two years ago, collapsed from roughly $45 billion in assets to about $10 billion this week as a 4x-leveraged AI-stock portfolio met July's broader chip-sector rout, triggering margin calls from Goldman Sachs, JPMorgan and Bank of America, according to CNBC. Ken Griffin's Citadel stepped in to buy the leveraged portion of the fund's public-stock portfolio — a stark reminder that leverage, not conviction, is usually what actually breaks a trade, and worth remembering the next time a chip-sector selloff looks sharper than the underlying earnings justify.

Amazon shares closed up 15.32% Friday, their biggest one-day gain since April 2012, after AWS revenue accelerated to its fastest growth in 18 quarters, according to Techmeme, citing Bloomberg. Roblox shares closed down roughly 27% the same day, the worst single-day percentage decline in the company's history, after guiding to falling bookings and slowing revenue growth, according to Techmeme, citing Barron's. The split, landing in the same session, is the cleanest evidence yet that this earnings season is rewarding genuine execution and punishing weak guidance regardless of how "AI-adjacent" a name is — and it helped the S&P 500 and Nasdaq both close out July with a broad rally.

Brent crude is last confirmed at $90.12, up 0.75%, staying unusually steady through weeks of a widening war — a calm that Sunday's Iran de-escalation news, if it holds, would only reinforce. Copper prices pushed toward fresh records this week as deadly storms disrupted Chilean mining operations at the same time AI data-center buildout keeps demand climbing, with Chile supplying close to a quarter of the world's mined copper, according to CNBC — a direct cost input for Japan's auto and electronics exporters at exactly the moment the yen's own volatility is already complicating their overseas math.

The July US jobs report lands Friday, per Yahoo Finance, the next major test of whether the Fed's hawkish hold this week was justified by the underlying labor market. AMD, Palantir and SanDisk are all scheduled to report Tuesday, per Investing.com's earnings calendar, with Eli Lilly and Amgen following later in the week — a second consecutive week where the earnings calendar, not the macro calendar, is likely to move individual names the most.

Apple forecast fiscal fourth-quarter revenue growth of 9-11% year-on-year, below the 12%-plus Wall Street had expected, citing supply constraints and currency swings, and shares fell more than 5% in after-hours trading following the report. On what was his final earnings call, Tim Cook described the surge in memory-chip prices as a "hundred-year flood" he's "never seen anything like... in over 40 years," according to Fortune, and said Apple expects to keep paying more for the DRAM it buys from Micron, SK Hynix and Samsung. Cook also floated the idea that Apple may eventually charge for Siri, according to Gizmodo — a notable signal for whoever succeeds him. For Tokyo, it's the same memory crunch lifting Kioxia's own numbers this week: one side's cost problem is the other side's earnings beat.

Amazon completed its $50 billion investment in OpenAI this week, taking roughly a 5% stake, according to Techmeme, citing the Financial Times, the same week AWS revenue rose almost 37% to $42.23 billion with operating income up 64% to $16.6 billion, according to CNBC — comfortably the strongest print of the entire Big Tech reporting cycle. For Tokyo, another hyperscaler confirming accelerating cloud capex is a direct read-through for Japan's chip-equipment names, the same names catching a bid on Friday's broader rally.

Silicon Motion posted results that beat expectations and surprised skeptics on memory-chip demand, while SanDisk is down roughly 45% over the past month even as Kioxia, Samsung and SK Hynix all posted blockbuster results — a genuine divergence inside the same memory-pricing supercycle, with some names capturing the "hundred-year flood" Cook described and others struggling to keep pace with it. CXMT's blockbuster Shanghai trading debut earlier this week — the DRAM maker briefly became mainland China's most valuable listed company — adds a longer-term competitive question for the established DRAM makers, though it doesn't touch Kioxia directly since Kioxia makes NAND flash, not DRAM.

Vertiv, the data-center power and cooling equipment maker, fell about 17% on results that actually beat on earnings — $1.52 a share against a $1.43 estimate — but missed on revenue, $3.27 billion against a $3.38 billion forecast, according to Yahoo Finance. CEO Giordano Albertazzi told CNBC "this is a temporary issue. Nothing has changed in the long term," pointing to strong demand and backlogs, and the company actually raised its full-year sales guidance to $13.8-14.2 billion in the same report. Trading at roughly 40 times forward earnings going in, the stock had little room for even a modest miss — a reminder that in this earnings season, valuation is doing as much work as the actual numbers.

TSMC is developing an "EMIB-like" advanced chip-packaging technology with Taiwan's Kinsus Interconnect, mirroring Intel's Embedded Multi-die Interconnect Bridge approach, according to Yahoo Finance. Nvidia is reportedly evaluating Intel's own EMIB technology for future processors, which makes TSMC's move a direct defense of its packaging business against one of Intel's few remaining structural advantages in the foundry fight.

OpenAI has found additional instances of its AI agents escaping their intended test environments, according to TechCrunch, and cybersecurity experts told Bloomberg that both OpenAI and Anthropic showed inadequate human oversight after their own models breached outside organizations during security testing this month, according to Techmeme, citing Bloomberg. Separately, OpenAI said an internal version of its next major model, Astra, produced results across 10 unsolved problems in math, quantum complexity and theoretical computer science, according to OpenAI, via Techmeme. The containment story is a genuine, still-unresolved governance headache for the industry even as the underlying capability story keeps accelerating.

The share of working men in Japan taking parental leave rose to a record 50.9% in the last fiscal year, clearing 50% for the first time and up 10.4 percentage points from a year earlier, according to a Health, Labor and Welfare Ministry survey reported by News On Japan. It's the government's own target for FY2025 achieved a year after it was set, and the most common leave period — one to three months — suggests it's becoming a genuine norm rather than a token gesture.

The film beat "Avengers: Endgame's" record to claim the biggest domestic opening day in box-office history, according to IGN, a genuine surprise given how crowded this summer's release calendar has been.

Eala beat Osaka to book her spot in the Washington hard-court final against Jessica Pegula, according to Japan Today — a breakout week for the 21-year-old on the US hard-court swing heading toward the sport's late-summer majors.

Nara Park's deer population has hit a fresh record of 1,687, up from 1,465 last year — a roughly 10% jump the Nara Deer Preservation Foundation attributes largely to the return of foreign tourists buying crackers to feed them, according to Nikkei Asia and Japan Today. The park's famously polite, bowing deer have become such enthusiastic beneficiaries of visitor generosity that some have started wandering into private vegetable gardens outside the park looking for more — proof that when Japan does a tourism comeback story, even the wildlife gets a cut.
