Trump hosts Xi in Washington Wednesday–Thursday with AI, Taiwan and the Iran war on the table, and a dozen tech CEOs at the state dinner — the week's real catalyst, not today's tape. Iran's Hormuz standoff and the Israel-Lebanon ceasefire both got worse over the weekend while WTI still eased on Aramco's pipeline-repair timeline — that gap between the war news and the oil tape is the thing to watch. In AI: Anthropic is weighing a new model launch ahead of its own IPO to answer GPT-6 Astra, and a zero-click RCE bug (Plugin4Shell) hit Claude Code, Codex, Copilot and Gemini CLI — Anthropic and OpenAI have already patched, Copilot and Gemini CLI have not.

Trump hosts Xi in Washington this week, with AI and Taiwan on the table.
Xi Jinping arrives Wednesday for the second Trump-Xi summit of 2026 (after May's Beijing meeting) — arrival ceremony and a Rose Garden military review Wednesday, the main bilateral Thursday, then a state dinner. Trade, AI, Taiwan, critical minerals and the Iran war are the agenda; Bezos, Pichai, Altman, Cook, Musk and Huang are all expected at the dinner table. Per Heritage Foundation, CSIS and Bloomberg
Trump bars CNN, MS NOW and Politico from the White House; legal fight already forming.
Trump announced Friday he was banning the three outlets over "FAKE NEWS" coverage; by Saturday their White House reporters had press passes confiscated and were turned away. All three say they'll sue. A First Amendment scholar at Columbia's Knight Institute called the move "pretty clearly unconstitutional" — echoes the AP's ongoing Gulf-of-Mexico-naming suit, which the administration has not won. No suit had been filed as of Sunday night. Per CNN and NBC News
Germany's AfD still can't turn a plurality into a government.
Two weeks after winning 43.8% and 39 of 83 seats in the Sept. 6 Saxony-Anhalt election — a historic high, still short of the 42-seat majority — every other major party is holding the firewall and refusing to govern with them. As of this weekend the state government remains undetermined, with no coalition math that works without AfD. Per Al Jazeera and Wikipedia's election tracker

Anthropic weighs a new model launch ahead of its own IPO.
Reuters-sourced reporting says Anthropic is considering releasing a new model before going public, aiming to blunt the momentum OpenAI's GPT-6 Astra has built with enterprise buyers — a notable tension given CEO Dario Amodei's own public call last week for an industry slowdown, backed by Altman and Musk. Per PYMNTS and AI Weekly
Plugin4Shell: a zero-click RCE hits four major coding agents at once.
Disclosed Sept. 17-18, the bug breaks the SHA-pinning that's supposed to lock an installed plugin to a reviewed commit — an attacker who controls the plugin repo can make a malicious branch resolve ahead of the pinned commit hash during checkout, while the agent still reports a clean, verified install. Add-ons typically run with the same access as the developer — source code, cloud creds, SSH keys, production systems. Anthropic patched Claude Code in 2.1.179; OpenAI patched Codex 0.146.0. GitHub Copilot was unpatched at disclosure; Google says it won't patch the deprecated Gemini CLI at all. Per The Register and Help Net Security
Huang: Nvidia will sell twice the chip volume next year.
Speaking Sept. 17 at King Charles's AI summit in Scotland, Jensen Huang said Nvidia expects to double unit chip sales next year across its full portfolio (data-center GPUs, networking silicon, laptop and robotics chips) — the same week reporting surfaced that both Anthropic and OpenAI are also scouting smaller 20–30MW data-center deals alongside their gigawatt-scale commitments. Per CNBC and Bloomberg
Quieter releases: Google shipped Gemini 3.8 Flash (Sept. 2), OpenAI's GPT Image 2.5 added a sketch-to-image feature (Sept. 8), DeepSeek released V4.1 Flash (Sept. 10), and OpenAI turned on Chrome-extension support inside ChatGPT's desktop browser (Sept. 18). Per AI Weekly and LLM Gateway

Tokyo is dark for Respect for the Aged Day, so Monday's Asia read leans on Friday's Hang Seng print. Europe closed the week ugly — autos and telecoms did the damage, not a macro shock — while US futures are drifting higher into the open on falling oil and ahead of Wednesday's Trump-Xi summit. Treasury yields haven't printed since Thursday; both 2Y (4.67%) and 10Y (4.94%) are dated. BTC is spot-only tonight — the CME futures feed 403'd on this data plan, so no forward mark.
📰 Themes Running the Cycle
AI capex goes physical → the AI trade cracksDay 82
What's new: Huang's Sept. 17 "twice the chips" call and Anthropic's reported pre-IPO new-model deliberations both landed the same week — the second one sits awkwardly next to Amodei's own slowdown essay, which he's publicly pushing while his company reportedly weighs a competitive launch anyway. Neither Anthropic's nor OpenAI's S-1 has surfaced yet.
Higher-for-longer, now coupled to a currency/bond crisisDay 82
What's new: nothing since Thursday's print — 2Y still 4.67%, 10Y still 4.94%, no fresh Fed data over the weekend. DXY ticked up 0.05% to 100.27 Friday-to-Monday. Genuinely quiet.
Iran: succession, Hormuz & the war that won't stay endedDay 82
What's new: Iran's parliament speaker Ghalibaf reiterated over the weekend that Hormuz stays closed until Iran's conditions are met and US commitments are implemented — hardening, not softening, the demands flagged Saturday. Israel's ceasefire with Lebanon is technically still holding per the official readout (no fire reported either direction as of the latest check), a materially calmer framing than Saturday's "violated twice" read — worth watching which version holds up through the week. WTI still eased to $100.30 Friday on Aramco's pipeline-repair timeline, unmoved by the rhetoric.

🔭 So-What for the Forest
Risk tone into the open is calmer than the weekend's headlines deserve: futures are up across the board on falling oil, not because Hormuz or Lebanon actually cooled off, but because Aramco's repair timeline keeps crude's risk premium capped for now. The transmission channel that matters most this week isn't the war — it's Wednesday's summit: any AI-chip-export or Taiwan surprise out of the Trump-Xi meeting would hit the mega-cap AI names (and by extension QQQ) faster and harder than another Houthi missile intercepted over Riyadh. The one exogenous wildcard: a Hormuz de-escalation this week would be a bigger oil-and-vol event than anything on today's calendar, and it's live given Iran-Oman talks are still moving even as Tehran's public demands harden.

Juno spacecraft: Mars is quietly dusting the whole inner solar system.
New analysis of interplanetary dust hitting NASA's Juno spacecraft points to Mars itself as a source of the zodiacal light — that faint pre-dawn/post-dusk glow skywatchers chase — meaning the Red Planet has apparently been sprinkling grit across cislunar space for eons without anyone noticing the source.

A Dutch food truck will trade your cigarette butts for pancakes.
Rotterdam's "WasteBar" hands out free poffertjes — the little Dutch mini-pancakes — in exchange for collected cigarette butts, turning beach and sidewalk litter cleanup into a genuinely popular street-food gimmick. Reported turnout has been strong enough that organizers are weighing a second cart. Per The Funny Times, September 2026 roundup
