CNBC Halftime Report
2026-05-18 · Hosted by Scott Wapner · CNBC
Executive Summary
The Halftime Report tackled the central question of whether the tech sell-off on May 15 — driven by the 10-year Treasury crossing 4.5%, WTI above $100/barrel, and no progress from the Trump-Xi summit — represents a buying opportunity or an inflection point. The S&P 500 was going for its seventh straight positive week (up ~10% on the year), but the run described as “dangerously narrow” by Rob Sechin, with the NASDAQ needing to fall 12.5% just to get back to its 50-day moving average. Key debates: Bill Ackman’s new Microsoft stake (broadly viewed as a compelling call), Anthropic’s $900 billion valuation on a $30 billion term sheet, Cerebrus at 134x trailing revenue, and whether AI IPOs arriving in public markets will compress valuations for existing names or attract fresh capital.
Key Stories & Changes
1. Tech Pullback Debate: Inflection or Speed Bump?
NASDAQ 100 up 17% in the prior six weeks; SMH ETF up for six straight weeks
Cerebrus IPO: 68% first-day gain, pricing it at over $100 billion market cap on a fully diluted basis — panelists described it as a “party like it’s 1999” feeling
Rob Sechin: Tape was “screaming overbought”; 6-week rally of 17% was the “11th best run since 1950”; 10 stocks doing all the work; rally is “dangerously narrow”
Brian Belski: Market is a discounting mechanism; earnings up 50% for tech in the quarter; best positioned US equity market in decades
Jenny Harrington: Market has been missing the second pillar (lower rates) that underpinned 2023/2024/2025 gains; now only has earnings growth to lean on; concern about losing the rate-cut “hope” as rates back up
Michael Hartnett (Bank of America): Bull capitulation in stocks and tech “likely complete in next few weeks”; early June “ripe for taking some off the table”; CPI above 4% historically leads S&P down 4% over next 3 months, down 7% over 6 months
Goldman Sachs trading note: “Tempting, but don’t fight this” — dips have been very shallow because long-only community is ready to pounce
2. Anthropic Valuation: $900 Billion on $30 Billion Term Sheet
Anthropic has agreed to a term sheet for a new $30 billion investment
Implied valuation: $900 billion — more than doubles its last price tag
Eclipses rival OpenAI which is valued at ~$850 billion in private markets
Revenue: Anthropic has topped a $35 billion annual revenue run rate (up from $30 billion earlier this year; was $9 billion at end of last year)
Investors in round: Sequoia and Altimeter co-leading; General Oak, Stragonoy participating; more expected to join
Drivers: Claude Code is a major revenue driver; Mythos (cybersecurity model) adding buzz; compute needs driving the fundraise
IPO potential: “As soon as the end of this year” according to sources
3. Bill Ackman’s Microsoft Stake
Pershing Square built position starting February at ~21x earnings
Ackman: Investors “underestimate resilience of M365 franchise”; Azure growth concerns are “misplaced”; views $190 billion Azure CapEx as growth CapEx, not maintenance
Microsoft: Largest analyst upside in Mag7 — +36% to median price target
Azure growing at 40%; M365 “endemic in every ecosystem”
Rob Sechin: Calls Microsoft “the highest quality tech name in the world”; Kevin Simpson: Has owned since 2013; Jenny Harrington: Wouldn’t buy from here personally but acknowledges quality
4. Cerebrus IPO Valuation Reality Check
Cerebrus trading at 134x trailing revenue — more than 5x Nvidia’s multiple
Total backlog: ~$25 billion, but $20 billion of that is a single OpenAI contract
Only ~$3.7 billion expected to be recognized in 2026-2027 combined
Must diversify customer base to justify trajectory
“Market is pricing in years of flawless growth”
Intel vs. Cerebrus as “canaries in the coal mine” for risk appetite — Intel’s move up on negative earnings described as “fringe element” and concerning
5. SpaceX IPO Timeline
S1 expected May 18-22; road show early June; first trade mid-June
Raise target: $70-75 billion (more than 2x all-time record)
Brad Gerstner’s thesis (mentioned): These companies have “already IPOed” via private rounds — retail investors getting access at much less asymmetric prices
Concern about IPO flows: Will SpaceX money come from cash on sidelines or force selling of existing tech holdings?
6. Key Analyst Calls of the Day
ConocoPhillips: Target to $136 from $128 (Argus) — “well-positioned to manage volatile oil/gas prices”
Chevron: Reiterated buy, $220 target (UBS) — higher than all-time high; enormous FCF
Netflix: Morgan Stanley reiterates overweight, $1,115 target — “engagement fears overblown, pricing power and ads opportunity underappreciated”
Palo Alto Networks: RBC target raised to $255; Kevin Simpson bought at $158 and $220
Freeport-McMoRan: Kevin Simpson new purchase at $63.50-$61.50 — long-term copper/data center electrification play
Banking sector (options): Bearish activity in XLF ETF — 2:1 puts vs. calls; $500K put buying at 46 strike for mid-September, bold bet sector goes nowhere by Jan 2027
Trends Identified
1. The Tug-of-War Thesis Is Now Explicit
The episode’s dominant meta-theme is an explicit acknowledgment that markets are in a tug-of-war between spectacular AI-driven earnings growth and worsening macro conditions (rising yields, sticky inflation, new Fed chair uncertainty). The bulls have been winning decisively, but the May 15 sell-off was described as the bears finally getting some traction back on the rope — particularly because the interest rate leg of the bull case is now working against the market instead of with it.
2. AI IPO Supply Wave Could Be a Market Structure Event
The arrival of SpaceX, Anthropic, and OpenAI in public markets within the next 12 months raises a structural question: Will the enormous capital absorption required to fill these order books come from fresh money (bullish) or from forced rotation out of existing AI/tech holdings (bearish)? The panel was divided, with Rob Sechin focused on watching the flows carefully as a key signal.
3. Cyber Security as the AI Enablement Trade
Kevin Simpson’s Palo Alto Networks call and his framing of cybersecurity as “not being disintermediated by AI but rather embracing it” represents a growing investment thesis: as AI is deployed enterprise-wide, the attack surface expands, and cybersecurity spending accelerates. The Palo Alto +46% in one month trade was validated by the RBC upgrade to $255.
4. Commodity Revival as Late-Cycle Portfolio Play
Multiple panelists and calls-of-the-day pointed toward energy and copper as legitimate portfolio additions: ConocoPhillips, Chevron (UBS), and Freeport-McMoRan (Kevin Simpson new buy). The rationale spans from near-term oil supply shock (Strait of Hormuz) to long-term copper demand from data center electrification — two different but reinforcing reasons to own hard assets in this environment. —-
Sentiment Analysis
Overall Market Sentiment: Mixed / Tug-of-War
The panel was genuinely divided — not in a performative way but because the data genuinely supports both bull and bear cases depending on time horizon and analytical weight given to earnings vs. rates.
Risk Factors Highlighted
CPI above 4% historically bearish: Bank of America’s Hartnett flags historical data showing S&P down 4% in the 3 months and 7% in 6 months after CPI crosses 4%; “early June ripe for taking some off table”
Narrow market concentration risk: One-third of the S&P 500 (equal-weight) is down 7%; 10 stocks driving almost all gains — this concentration is fragile
Rate hike debate: Fed futures pricing in possible hike; Worsh taking over amid internal Fed tension (Bowman/Myron dissent); credibility concerns
Anthropic/OpenAI IPO absorption risk: If $30B+ in new AI company shares must be absorbed by public markets, existing tech holders may need to sell to make room
Cerebrus single-customer risk: $20B of $25B backlog is OpenAI; if that relationship fractures (see Apple/OpenAI) or delays, the revenue story collapses
Iran/oil supply shock duration: If Strait of Hormuz remains closed through summer, energy prices feed through to everything; “non-energy things that moved higher won’t be put back in the bottle”
Intel valuation disconnect: Described as having “nothing behind it” from a fundamental perspective despite the government backstop narrative; if retail enthusiasm fades, could be a canary for broader speculative excess
AI winter tail risk (low probability): Even a low-probability AI disappointment event combined with current positioning levels could trigger a violent deleveraging cascade
