Q1 2026 EPS growth is on pace for the largest y/y growth rate in five years, mostly due to record AI capex, which in turn is now largely funded through massive new issuance of IG debt https://t.co/ooh9vSfCHo
Chart 2 from the Dallas Fed (Feb 10, 2026) plots monthly AI-related bond issuance (red diamonds) and a duration-adjusted 10‑year equivalent measure (blue bars), showing a large surge in issuance in late 2025–early 2026. This directly supports the tweet’s point that record AI capex is being financed through massive new investment‑grade debt issuance.

Research Brief
What our analysis found
Q1 2026 earnings season is shaping up to be a landmark quarter for corporate America. According to FactSet's Earnings Insight report dated May 1, 2026, the blended year-over-year EPS growth rate for the S&P 500 stands at 27.1%, with 63% of companies having reported. If this rate holds, it would represent the highest earnings growth since Q4 2021's 32.0% and mark the sixth consecutive quarter of double-digit growth. A remarkable 84% of reporting companies have beaten EPS estimates, well above the five-year average of 78%, with aggregate earnings coming in 20.7% above estimates — the highest surprise percentage since Q1 2021.
The engine behind this surge is an unprecedented wave of AI-related capital expenditure. The five largest hyperscalers — Amazon, Alphabet, Meta, Microsoft, and Oracle — are projected to spend between $660 billion and $805 billion on capex in 2026, with the vast majority directed toward AI compute, data centers, and networking infrastructure. Morgan Stanley's most recent forecast, updated May 4, 2026, places the figure at approximately $805 billion, nearly doubling 2025 levels. Cumulative AI-related spending from 2025 to 2029 is expected to exceed $2.7 trillion.
To finance this historic buildout, Big Tech has turned aggressively to debt markets. Hyperscalers issued a record $120 billion in investment-grade corporate bonds in 2025 alone — a 500% surge from 2024. Q1 2026 saw record overall IG issuance of $582 billion, with Amazon contributing $54 billion, Alphabet $31 billion, and Oracle $30 billion. JPMorgan estimates that AI-driven companies may need to raise up to $1.5 trillion in IG bonds over the next five years to sustain this pace of investment.
Fact Check
Evidence from both sides
Supporting Evidence
Q1 2026 EPS growth confirmed near five-year highs
FactSet's May 1, 2026 Earnings Insight report confirms a blended year-over-year EPS growth rate of 27.1% for Q1 2026, which would be the highest since Q4 2021's 32.0%, directly supporting the claim that this is the largest growth rate in five years.
Hyperscaler AI capex at record levels
Multiple independent sources corroborate massive AI spending in 2026. The Futurum Group reported projected capex of $660–$690 billion for the top five hyperscalers, CreditSights estimated $602 billion with 75% allocated to AI, and Morgan Stanley's May 2026 update raised its forecast to approximately $805 billion — all confirming record AI capex driving corporate earnings.
Record investment-grade debt issuance to fund AI
Big Tech issued a record $120 billion in IG corporate debt in 2025, a 500% increase from 2024, according to Tickeron and M&G Investments data. In Q4 2025 alone, Oracle, Meta, Google, and Amazon issued approximately $90 billion in bonds, and Q1 2026 saw record total IG issuance of $582 billion with hyperscalers as major contributors.
Tech sectors leading EPS growth
Information Technology (50.0%), Communication Services (53.2%), and Consumer Discretionary (39.0%) are the sectors with the highest year-over-year EPS growth in Q1 2026, confirming that AI-adjacent industries are the primary drivers of the overall earnings surge.
Contradicting Evidence
Growth is heavily concentrated in a few mega-cap tech names
The jump from initial Q1 2026 EPS growth estimates of 12.6–13.1% to the current 27.1% blended rate is largely attributable to outsized positive surprises from a handful of Magnificent 7 companies like Alphabet, Amazon, and Meta. This concentration means the headline growth figure may overstate the breadth of earnings improvement across the broader S&P 500.
Several sectors show muted or negative growth
While tech-heavy sectors are surging, other areas including Health Care, Energy, and parts of Communication Services were initially projected to show flat or negative earnings growth, suggesting the claim that AI capex is broadly driving EPS growth oversimplifies a more uneven picture.
Massive debt issuance introduces rising credit risk
The flood of AI-related IG bond issuance has led to wider credit spreads for some hyperscalers, notably Oracle and Meta, and increased the cost of insuring their debt. This signals that markets are beginning to price in heightened credit risk associated with the scale of borrowing, raising questions about long-term sustainability.
Uncertainty about AI investment returns
Economists and credit analysts have flagged concerns about what happens if the profit-making potential of AI fails to materialize at the scale implied by current spending levels. If AI revenue growth disappoints, the massive debt load could become a drag on future earnings rather than a catalyst, potentially reversing the very EPS growth the investment is currently fueling.
