Stock-Market Research Dispatch — 2026-05-19
Auto-generated by daily research routine. Not a source; not ingest-pending material. Summary of what changed in the wiki today.
Macro context
SpaceX S-1 reportedly drops tomorrow (May 20). The Trump-Xi summit (May 12-15) closed with warm rhetoric and zero operational tech concessions — H200s cleared for 10 Chinese buyers but zero have shipped; rare earth flows still ~50% below pre-restriction levels. The November 10, 2026 REE binary catalyst is unchanged; the May 12 Geneva trade truce adds a second binary catalyst expiring "this autumn" (August-September 2026). Both land in H2 2026, compounding with each other.

Significant wiki updates
SpaceX IPO (spacex, spacex-ipo-index-inclusion-mechanic): S-1 reportedly filing May 20, pricing June 11, listing June 12 as SPCX at $1.75-2T with 3.3% float. Index cadence now mostly resolved: CRSP Day 5, VettaFi Day 0 (new rule May 15), Nasdaq-100 Day 15 (new fast-entry rule May 1). Day 10 still unidentified. Passive buying estimate: $7B (Nadig) to $60B (ex-Goldman) vs $66B float. Front-running documented. Trade hypothesis: position before Day 15; exit into or shortly after Nasdaq-100 inclusion; crowded trade.
CoWoS (cowos-packaging-capacity-crunch): TSMC May 14 symposium confirmed: yield >98%, 130K WPM target by late 2026 (from ~35K late 2024). Despite 4x capacity expansion, only "slight easing" expected — demand growing as fast as supply. TSMC outsourcing overflow to ASE/Amkor. BESI entity created: Q1 revenue €184.9M (+28.3% YoY), orders €269.7M (>2x YoY).
El Niño (el-nino-2026-commodity-impact): Friedberg's "99% confidence" is officially overstated — NOAA says 82-96%. Calibration entry logged. Key material finding: urea +53.7% March 2026 (the fertilizer shock has materialized). World Bank projects -2% overall ag price index (contradiction: specific commodities spike; broad index doesn't yet). NOAA subsurface temps in 2026 running warmer than 1997-98 at same stage — the scale claim holds.
CHIPS 48D correction (us-industrial-policy-tariff-shield): Prior wiki had "Senate draft expanding 25%→30%." Corrected: One Big Beautiful Bill Act signed July 4, 2025 enacted 48D at 35% and extended construction-start deadline to December 31, 2026. SIA + 17 trade groups sent formal letter to Congress May 12 urging extension beyond December 31, 2026. Mechanism page Step 3 corrected; incentive shift now ~10pp (not 5pp). The December 31, 2026 construction-start deadline + July 1 Phase 2 gate create convergent H2 2026 policy uncertainty for anyone considering breaking US fab ground.
Helium (new chain: helium-supply-crisis-semicap): The Iran/Hormuz disruption has a helium channel not previously in the wiki. Ras Laffan strikes removed ~30% of global semiconductor-grade helium. Samsung/SK Hynix sourced ~2/3 from Qatar → rationing. TSMC (3-6 month inventory, recycling) and US fabs (42.6% production) insulated. Linde (LIN) + Air Products (APD) control global distribution → pricing power; APD raised FY2026 guidance citing helium explicitly. "Real crisis begins after ceasefire" — restoration takes months. Sub-3nm chips need more helium per wafer. LIN/APD added to picks-and-shovels-leading-edge-fab-buildout.
China geopolitics (china-rare-earth-november-2026-deadline): Summit vagueness documented. REE scenario probability: extension ~40%, selective reinstatement ~40%, full reimposition ~20%. Full reimposition = extraterritorial controls are unprecedented + spike terbium/dysprosium immediately.
Taiwan (taiwan-chokepoint-to-allied-reshoring): PLA 2027 readiness target added. December 2025 exercises = largest Taiwan-focused drills ever. Iran/Hormuz now compounds Taiwan's energy import vulnerability — two-front supply constraint. This creates tension with Chamath's "18-month Taiwan fades" framing: if PLA reaches readiness in 2027, the urgency window may be approaching, not receding.
Calibration logged
Friedberg "99% confidence" → NOAA 82-96% (pattern: overconfidence/expert-authority). See CALIBRATION.md.
Step 4b — Valuation snapshots
WebFetch blocked (HTTP 403) — price data unavailable. Continuing precedent from May 18: snapshot sections on existing concept pages remain stale. New pages today (helium, el-nino concept) have no snapshot section; will add on first WebFetch-enabled run.
Open questions elevated this run
- SpaceX Day 10 index — unidentified. Watch for index-provider press releases pre-IPO.
- China Blackwell offshore compute routing — new question page created. BIS rule change risk is the key watch item.
- July 1, 2026 Section 232 Phase 2 gate — 43 days out. Convergent with December 31 48D deadline.
- H2 2026 binary catalysts stack: trade truce expiry (autumn) → REE deadline (November 10) → potential S&P 500 inclusion for SpaceX (~December if rule passes). Three macro catalysts in a 5-month window.
