🔥 SpaceX Files for the Largest IPO in History, AI Valuations Hit New Records, Ceasefire Still Unsigned - Here's the State of the Market in May 2026

Summary for Investors & Entrepreneurs

1. Key Themes

Theme 1: AI Concentration in Private Markets Has Reached a New Extreme

The top of the private market leaderboard is overwhelmingly AI-native, with five of the top six companies being AI-first. Combined, the three largest AI companies (SpaceX/xAI, OpenAI, Anthropic) represent well over $2 trillion in private valuation alone.

"Five of the top six names are AI-first. The SpaceX S-1, OpenAI's $852B close, and Anthropic's resistance to $800B offers all landed within six weeks of each other. The private AI market is not waiting for public markets to catch up."

Theme 2: SpaceX's IPO Would Shatter All Historical Records

SpaceX's planned Nasdaq debut under the ticker SPCX represents an unprecedented liquidity event that dwarfs any prior IPO in history — by more than 2x.

"It formally filed its S-1 on May 20, targeting a Nasdaq debut under SPCX as early as June 12, at a valuation of $1.75 to $2 trillion. If it prices at the midpoint, it would be the largest IPO ever recorded, more than doubling Saudi Aramco's $29B raise."

Theme 3: M&A Is the Dominant Liquidity Path — and Deal Sizes Are at a Decade High

With few public listings, M&A has become the primary exit route. But the market is bifurcating sharply: fewer deals, much larger ones, concentrated in energy infrastructure and AI.

"Average deal size has reached $260M in 2026 to date, the highest figure in the dataset going back to 2015, surpassing even the post-pandemic 2019 high of $208M."

"The era of broad-based deal activity has given way to concentrated, high-conviction consolidation in energy, infrastructure, and AI."

Theme 4: Public Market Multiples Are Re-Rating Upward After Finding a Floor

After a correction that began in late 2024, elite software and AI names are recovering their revenue multiples, with the top-10 average jumping meaningfully month-over-month.

"Top 10 average moves to 19.3x and median to 16.3x, up from 16.1x average and 13.8x median in April. In short: the floor held in April and multiples are re-rating upward in May."

---

Theme 5: Cybersecurity Commands Scarcity Premiums in M&A

Strategic buyers — particularly large enterprise platforms — are paying 15x+ revenue for cybersecurity assets, a premium unavailable in most other software categories.

"Strategic buyers are paying up for cybersecurity scarcity. LayerX and Astrix Security (16.0x, acquired by Cisco) both cleared above 15x revenue, consistent with the broader trend of enterprise security platforms commanding premiums unavailable in other software categories."

2. Contrarian Perspectives

Perspective 1: Markets Are Pricing in Geopolitical Resolution That Hasn't Happened

The consensus view might be that elevated oil prices and an unresolved war in the Middle East would suppress equity markets. The data says the opposite. Equities are hitting all-time highs while the Strait of Hormuz remains blocked and oil trades 40%+ above pre-war levels — suggesting markets are systematically front-running diplomatic outcomes.

"The pattern from April held: markets price in resolution before the diplomacy delivers it. 84% of S&P 500 companies beat EPS estimates in Q1, which gives the market cover to look through the oil shock. Firm inflation and elevated energy prices are tempering Fed rate cut expectations, but equities are ignoring that too."

"Brent is trading around $103 per barrel, still more than 40% above pre-war levels, and the Strait remains functionally blocked. The S&P 500 hit a record 7,412 and the Nasdaq set all-time highs on May 11, even as Trump rejected Iran's latest proposal the same week."

Perspective 2: Anthropic May Be More Valuable Than OpenAI — and the Market Is Starting to Agree

The conventional wisdom positions OpenAI as the clear AI leader by valuation. But secondary market pricing and revenue trajectory suggest Anthropic is closing the gap — and may have already crossed it on some measures.

"Secondary markets are now pricing Anthropic at a premium to OpenAI for the first time."

"Annualized revenue reportedly hit $30B by end of March, up from $9B at end of 2025." (Anthropic's revenue tripled in roughly one quarter.)

"Bloomberg reported in April that investors have offered $800B+ for a new round, which Anthropic has resisted" — suggesting management believes the company is worth even more.

---

Perspective 3: Larger M&A Deals Are Closing at Lower Revenue Multiples Than Smaller Ones

The intuitive assumption is that premium size commands premium pricing. May's data inverts this: the largest deals are closing at more disciplined multiples than the prior month's smaller transactions.

"Top 10 largest deals median: $14.5B EV at 3.6x revenue, versus April's $6.5B EV at 5.6x revenue. Deal sizes are larger but multiples are more disciplined."

5. Operating Insights

Insight 1: Revenue Multiples Reward Efficiency Discipline as Much as Growth

The public market data shows that EBITDA margin is increasingly a co-equal driver of premium multiples — not just growth rate. AppLovin's 85% EBITDA margin at 40% growth commands a higher multiple than many faster-growing but less efficient peers. Operators should model their businesses toward high-efficiency profiles before any public market event.

"AppLovin (17.8x, up from 16.3x) stands out on efficiency: 85% EBITDA margin paired with 40% growth."

"The spoiler: The gap between elite and median has never been wider on efficiency metrics."

---

Insight 2: M&A Has Become the Primary Exit Strategy — Especially for Cybersecurity

With the IPO window narrow and only the very largest companies able to access public markets, operators in cybersecurity and infrastructure should actively position for strategic acquisition. The data shows strategic buyers (Akamai, Cisco) are paying 15–20x revenue for differentiated security assets with no sign of price fatigue.

"In light of very few public listings in the last few months, M&A has surged to become the more critical path for liquidity."

"LayerX and Astrix Security both cleared above 15x revenue, consistent with the broader trend of enterprise security platforms commanding premiums unavailable in other software categories."

6. Overlooked Insights

Insight 1: Anthropic Is Actively Resisting Its Own Fundraise at $800B+

Most coverage focuses on the size of AI funding rounds as a bullish signal. The more interesting data point here is that Anthropic is turning down capital at $800B+ — suggesting either extreme confidence in continued appreciation, concern about valuation anchoring, or strategic optionality around timing. This level of fundraising discipline at this scale is historically rare and worth watching.

"Bloomberg reported in April that investors have offered $800B+ for a new round, which Anthropic has resisted. Annualized revenue reportedly hit $30B by end of March, up from $9B at end of 2025."

Insight 2: The Efficiency Gap Between Elite and Median Companies Is at a Historic Wide

Buried in the multiples section as a "spoiler" teaser, this data point has significant implications for how investors should screen portfolios and how operators should benchmark themselves. A widening efficiency gap suggests median-quality companies face a structurally harder multiple environment even as top-tier names recover.

"The gap between elite and median has never been wider on efficiency metrics. Top 10 average EBITDA margin holds at 38% (unchanged since April), with the overall market median ticking up to 2.3x from April's 2.2x."
