Markets Rally on Middle East Peace Hopes, SpaceX IPO Buzz
European and global equity markets rose sharply after US President Donald Trump called off a planned strike on Iran and suggested an imminent framework agreement, which also pushed oil prices lower. Germany’s DAX gained 1.6% to 24,604 points, while MDax and EuroStoxx 50 rose about 1.8%. Travel-related stocks (Tui, Lufthansa, Fraport) posted gains of roughly 6–8%. U.S. indices recorded strong daily gains ahead of the high-profile SpaceX IPO, which is expected to be the largest ever and is cited with an implied valuation near $1.8 trillion; Anthropic and OpenAI IPOs were also noted as forthcoming. Brent and WTI crude fell more than 2% to about $88.35 and $85.13 per barrel respectively. Asian markets and leading tech names also climbed amid the risk-on mood.
Tech Stocks Rally After U.S. Ceasefire; Meta Debuts Muse Spark
U.S. and Iran agreed to a conditional two-week ceasefire that includes a temporary reopening of the Strait of Hormuz, triggering a global relief rally in technology shares. Earlier coverage noted broad gains for major U.S. tech names (Meta, Amazon, Alphabet, Nvidia) and the debut of Meta’s Muse Spark AI model; this CNBC piece highlights Asian semiconductor and equipment makers leading the surge. Taiwan Semiconductor Manufacturing Company, SMIC, Tokyo Electron, Advantest, Renesas, Fujikura, SK Hynix and Samsung all posted double-digit or high single-digit gains. Samsung also forecasted an eightfold jump in Q1 profit driven by AI demand for high-bandwidth memory (HBM). The article stresses lingering supply-chain risks — notably strained helium supplies after attacks on Qatari helium facilities (Qatar produces roughly 30% of global helium) — and notes oil prices fell on the ceasefire news, easing potential margin pressures for chipmakers.
AI Rally Climbs as Oil Volatility Rattles Markets
U.S. markets saw divergent forces last week as ongoing enthusiasm for artificial intelligence lifted tech indexes while rising oil prices and renewed U.S.-Iran tensions injected volatility. Semiconductor stocks swung sharply after mixed company results and geopolitical headlines, with Apple expanding a multiyear chip partnership with Broadcom and SK Hynix debuting strongly in the U.S. Meta moved to monetize its AI investments — announcing plans for a cloud business, launching the Muse Image and Muse Spark 1.1 models and indicating it will charge developers — and Reuters reported Meta plans to manufacture a custom AI chip co‑designed with Broadcom and built by TSMC. Crude oil spiked after an attack near the Strait of Hormuz and subsequent U.S. strikes on Iranian targets, boosting energy names and pressure on companies sensitive to fuel costs and inflation expectations.
