The Kospi closed down roughly 5% Monday, with Samsung Electronics and SK Hynix both falling close to 9%, unwinding a large share of Friday's record-breaking 17.9% single-day surge that had seen the same two stocks jump 27-30%, according to Bloomberg and Seoul Economic Daily. It's a sharp reminder that Friday's move was as much a short-covering snapback as a fundamentals repricing, and it directly explains why Tokyo's own chip-equipment names — which rode the same wave Friday — gave up so much more ground than the broader Nikkei today.

Brent crude fell sharply Monday as President Trump held off a planned large-scale strike on Iran, citing the "perimeters of a deal" on the Strait of Hormuz, with new talks set to begin Monday, according to CNBC and Al Jazeera. Iran's own defense ministry has pushed back on Trump's framing, and OPEC+ separately approved roughly 188,000 barrels a day of additional September output while signaling a pause after that, completing the phased unwind of its 2023 voluntary cuts, according to CNBC. The relief is real but conditional — no actual breakthrough has been confirmed, and a similar memorandum collapsed within a month back in June.

AstraZeneca has held talks with Bristol Myers Squibb on a merger that would combine the two into a roughly $400 billion pharmaceutical giant, according to the Financial Times, via CNBC and The Guardian. AstraZeneca is currently valued around $263 billion and Bristol Myers Squibb around $133 billion; a combination would push the pair toward the fourth-largest drugmaker globally by market value and mark a striking reversal for AstraZeneca, which rebuffed a $118 billion Pfizer approach in 2014. Both companies carry large oncology franchises, which is likely to draw antitrust scrutiny if talks advance.

A firmware flaw in Coldcard hardware wallets, tracing to a 2021 release with a predictable random-number generator, has been exploited in a fourth wave, pushing total losses close to $89 million from more than 4,500 addresses, according to CoinDesk and Cointelegraph. Researchers still can't confirm whether one operator is running all four waves. Bitcoin itself slipped under $63,000 Monday despite the Iran de-escalation, with the Coldcard losses adding to the pressure, according to CoinDesk.

The Federal Reserve held its policy rate steady for a second straight meeting last Wednesday under Chair Kevin Warsh, but three regional presidents — Cleveland's Beth Hammack, Minneapolis's Neel Kashkari and Dallas's Lorie Logan — dissented in favor of a hike, the first three-way hawkish dissent since 2016, according to Bloomberg. The split is still shaping how traders read Warsh's credibility on the inflation fight, a dynamic layered on top of this week's currency-intervention story since US rate expectations are one of the two levers, alongside intervention, now driving the yen.

SpaceX is set to report its first earnings as a newly public company Tuesday, and analysts are watching five numbers in particular: Starlink subscriber growth, launch cadence, Starship program burn rate, free cash flow, and the gap between reported revenue and the assumptions baked into its $1.4 trillion valuation, according to The Motley Fool. It's the most closely watched debut earnings print of the year outside the Magnificent Seven, and a clean beat or miss will likely set the tone for how the market treats other richly valued private-to-public space and AI infrastructure names.

Alibaba said its 2.4-trillion-parameter Qwen3.8-Max model tops rival Kimi K3 on some benchmarks and plans to release the weights for Qwen3.8-Max and a smaller Qwen3.8-27B variant next week, according to Bloomberg, via Techmeme. Nikkei Asia separately reports the "second only to Fable 5" framing some coverage attached to the release doesn't hold up under scrutiny, according to Nikkei Asia — a useful check on how much of the open-weight race is genuine capability versus marketing framing.

Robinhood's prediction-markets revenue surged more than tenfold year-over-year to $156 million in the second quarter, topping both its stock and crypto trading revenue for the first time as speculators shift toward real-world event betting, according to The Information, via Techmeme. It's a structural shift in how the company makes money, and it lands the same week New York state sued rival platform Kalshi over unlicensed betting operations, according to The Daily Hodl — a regulatory overhang the whole prediction-market category will have to navigate.

Four US states have rolled back or paused data center tax incentives and nine others are considering repeal measures, a shift that could add 7% or more to equipment costs for AI infrastructure buildouts, according to The Information, via Techmeme. It's a quiet but real cost headwind for the hyperscaler capex story that's been the single biggest demand driver for Japan's chip-equipment names all year.

Japanese startups are rushing to enter defense drone production as the government looks to reduce dependence on Chinese industrial drones, which currently control 91% of Japan's market, according to Nikkei Asia, via Techmeme. It's a direct extension of the broader economic-security push already reshaping procurement across Japan's defense and industrial names.

Uzbekistan and Kazakhstan are both building out AI data center capacity, led by Uzbekistan's 6-megawatt TAS-1 facility due by year-end and Kazakhstan's planned 125-megawatt site targeting 100,000 Nvidia chips by 2027, according to Nikkei Asia, via Techmeme — another data point on how far the AI infrastructure buildout is spreading beyond the US, China and Japan.

"Spider-Man: Brand New Day" posted a $927 million global debut, the second-biggest opening weekend in box-office history behind only "Avengers: Endgame," according to Variety. The film captured 81% market share in South Korea and opened to $121 million over five days in China, according to Variety and Variety.

Ariana Grande's representative confirmed she plans to take a "step back" from visibility once her current tour ends, citing ongoing public scrutiny, according to Pitchfork and BBC. No specific timeline was given for a return.

Massive Attack called it a "surreal experience" being banned from performing in Singapore after displaying a Palestinian flag onstage during a prior show, according to The Guardian. The band said the ban follows a pattern of pro-Palestinian messaging at its recent performances.

Hong Kong's Chiikawa fans kept spending at the character's pop-up despite days of heavy rain forcing organizers to cancel a planned roundabout appearance, according to South China Morning Post — a small but telling sign of how durable the character's commercial pull is across the region, on the heels of its Japanese theatrical debut clearing 3.05 million admissions and 4.4 billion yen in its first ten days, according to Livedoor News.

Osamu Akimoto is drawing a new one-shot chapter of Kochikame — one of the longest-running manga series in Japanese publishing history — to mark its 50th anniversary, according to Anime News Network. The comedy series about a bumbling Tokyo police officer ran for 40 years in Weekly Shonen Jump before ending its regular run, and the milestone one-shot is a reminder of just how deep its cultural footprint runs in Japan.

The maker of Japan's beloved Garigari-kun popsicle is testing the idea that eating a frozen treat right before heading out into summer heat works as a kind of "pre-cooling agent," according to SoraNews24 — a delightfully backwards piece of self-serving science that Japan's convenience-store culture was always going to produce eventually.
