📈 AI Stock News — 2026-04-18 06:15

Market Snapshot: S&P 500 closed at 7,123 (+3.5% on the week), Nasdaq hit 24,443 (+5.4%). VIX collapsed from 31 in March to 17.53 as the Iran ceasefire eased oil prices from $112 to the $80s, unwinding the stagflation trade and lifting tech multiples. The Global X AI ETF (AIQ) punched through a fresh 6-month high above $54.

Key Movers:

• NVDA — On a tear in April after a shaky March. Nvidia confirmed it will surpass its prior $500B estimate for Blackwell/Rubin orders and revenue through end of CY2026, signaling sustained AI chip demand. Upgraded to Buy by multiple analysts as the AI trade regains momentum.

• META — Raised 2026 capex guidance to $115B–$135B, reflecting aggressive AI infrastructure buildout. Stock benefiting from the broader tech rally.

• IONQ — Surged ~19.4% after announcing quantum networking milestones and securing a new DARPA contract. One of the week's biggest AI-adjacent movers.

• PLTR — Trading around $146, ranging $143–$148 on April 17. Continues steady climb on government AI contract momentum.

• ARM — Now holds ~50% of the hyperscale AI server CPU market, up from 18% in 2024. Also invested $60M in autonomous driving startup Wayve alongside AMD and Qualcomm.

• Ciena (CIEN) — Blowout fiscal Q1: revenue $1.43B (+33% YoY), EPS doubled to $1.35. AI networking infrastructure play surging.

Analyst Moves:

• TXN — Stifel upgraded to Buy (from Hold), PT raised to $250 from $215. FCF inflection expected after years of heavy capex.
• NOW (ServiceNow) — UBS downgraded to Neutral (from Buy), PT slashed to $100 from $170 on concerns about AI disruption to its competitive moat.
• DDOG (Datadog) — Upgraded on AI-driven observability demand.
• SNDK (SanDisk) — Further upside seen ahead of Q3 report (April 30), driven by AI-fueled NAND flash boom.

Macro & Regulatory Context:

• Iran ceasefire is the week's macro catalyst — crude oil retreat removed the stagflation overhang that had been compressing tech valuations.
• New bipartisan MATCH Act introduced in the Senate to harmonize AI chip export controls among U.S. allies.
• BIS revised its review policy for H200/MI325X-equivalent chip exports to China from "presumption of denial" to "case-by-case review."
• 25% tariff on AI chips not destined for U.S. supply chain remains in effect (since Jan 15, 2026). South Korea facing mounting pressure from this policy.

👀 Watch Today:

• IONQ — After a 19%+ surge on the DARPA contract news, watch for continuation or profit-taking. Quantum AI names tend to see volatile follow-through.
• NVDA — The $500B+ order confirmation is a major demand signal. With VIX low and tech surging, NVDA is the bellwether for the entire AI trade this week.
