Fed decision and Big Tech earnings drove market volatility
Last week’s market swings were driven by a hawkish Federal Reserve meeting, volatile chip-stock moves and a key round of Big Tech earnings. The Fed left interest rates unchanged while three of 12 policymakers voted for a hike, and Treasury yields jumped (the 10-year rose above ~4.67%, 30-year above ~5.2%). A forced liquidation at the leveraged hedge fund Situational Awareness amplified a reversal in the AI hardware-versus-software trade. Hyperscaler results showed contrasting outcomes for AI investments: Microsoft produced $19 billion in quarterly free cash flow, Amazon raised full-year capex by $20 billion while AWS posted its fastest revenue growth in 18 quarters, Meta posted strong ad growth but a steep (~91%) drop in free cash flow, and Apple beat revenue and earnings but warned of supply and memory-cost headwinds.
Big Tech earnings and a Federal Reserve decision influence corporate ad budgets, AI infrastructure spending and market volatility, which affect advertising demand and AdTech infrastructure.

Three Forces Drove a Volatile Week for Markets
A sharp sell-off on Friday erased earlier record highs as a strong jobs report pushed the U.S. 10-year Treasury yield above 4.5% and dimmed hopes for a near-term Federal Reserve rate cut. Tech and chip stocks led the decline after mixed earnings results and high expectations — Broadcom plunged after weaker-than-expected revenue and guidance, while Palo Alto Networks and CrowdStrike fell after failing to exceed lofty forecasts. A rotation into defensive sectors produced weekly winners such as Eli Lilly and Wells Fargo. Market-moving supply dynamics also featured prominently: SpaceX filed for a large IPO, Anthropic confidentially filed, and Alphabet announced plans to sell $85 billion in stock; Jim Cramer warned that a flood of new shares could pressure the market further.
Rising Yields Pressure Markets; AI and Retail Stocks Held
Rising long-term bond yields and higher oil prices weighed on US stocks the week of Aug. 22, 2026, interrupting multi-week gains and increasing market volatility. The Treasury Department said it would more than double buybacks of longer-dated government debt, briefly easing yields. AI-related infrastructure and semiconductor names saw volatility after supplier shifts (Marvell announced a broad partnership with Google) and reports that Broadcom is exploring a large debt-backed AI financing deal. Memory and retail stocks diverged: Micron remains a high-conviction holding amid signs of durable demand, while a busy week of retail earnings produced mixed results across Home Depot, Lowe’s, TJX, Walmart, Target, Ross Stores and BJ’s Wholesale.
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.
