The S&P 500 closed at a record high of 7,757 points on Friday, marking its 26th all-time high this year and the 122nd since the start of 2024. The market has continued to climb amid persistent concerns over geopolitical tensions, high interest rates, and debates about an AI bubble.

Addressing widespread skepticism about the market's ability to absorb record equity issuance volumes, John Flood, Managing Director and Head of Americas Equity Execution Services at Goldman Sachs, stated, "Yes. The S&P 500 can reach 8,000."

The bank projects total US equity issuance of approximately $700 billion in 2026, a historic record, but notes this represents only about 1% of market capitalization, in line with the average from 2015 to 2019.

Record Issuance Volumes, but a Low Ratio to Market Cap

Goldman Sachs forecasts that 2026 will be a record year for US equity issuance. Breaking it down, IPO issuance is expected to be slightly over $225 billion, with other offerings (including follow-ons, convertible bonds, and SPACs) totaling around $450 billion, for a combined sum of approximately $700 billion.

The key factor, however, is the proportion. This total volume is equivalent to roughly 1% of the Russell 3000 index's market capitalization, aligning with the average annual issuance levels from 2015 to 2019.

On a quarterly basis, US companies raised a combined $252 billion in the second quarter of 2026 through IPOs, follow-ons, convertible bonds, and SPACs, breaking the previous single-quarter record of $234 billion set in the first quarter of 2021.

In terms of follow-on offerings, the second quarter contributed $70 billion, bringing the year-to-date total (as of July) to $105 billion, the highest for the same period since 2021. However, John Flood pointed out that when considering issuance volume relative to market size and the number of deals, "this is more a normalization than a boom," as both metrics are slightly below historical averages.

Share Buybacks as the True Anchor

Despite the high issuance volume, the resilience of share buybacks is underestimated by many investors.

Share buybacks by S&P 500 constituents grew 11% year-over-year in the second quarter of 2026. Although hyperscalers are redirecting cash flow from buybacks to capital expenditures, other sectors like banking and semiconductors are expanding their repurchase programs.

Year-to-date, US corporate buyback authorizations have reached a record $989 billion.

Goldman Sachs estimates that total US open-market stock buybacks for the full year 2026 will reach $1.4 trillion. This figure not only covers the approximately $700 billion in primary market issuance but is also sufficient to offset potential additional supply from the expiration of IPO lock-up periods. Even under the assumption that all unlocked shares are sold immediately, demand would still outweigh supply.

AI as the Core Driver of the Issuance Wave

The 2026 equity issuance is highly concentrated. In both IPOs and follow-ons, the top three largest offerings account for nearly half of the year-to-date total issuance volume.

By sector, AI-related issuance constitutes about 40% of US equity follow-on offerings. The Technology, Media, and Telecom (TMT) sector accounts for nearly 30% of year-to-date follow-on offerings, more than double its average share over the past five years. The healthcare sector, traditionally the largest contributor, remains so this year.

The fundamental logic behind this trend is the demand for AI investment. Goldman Sachs cites market consensus expectations that hyperscaler capital expenditure will exceed $1 trillion annually in the coming years, surpassing 100% of their operating cash flow by 2027.

Recent discussions between Goldman Sachs and investors indicate that "most equity investors expect hyperscaler capital expenditure to exceed consensus estimates, and that other companies will also raise funds for their AI investment plans."

Debt as the Primary Source, Equity as a Supplement

Given the enormous capital expenditure requirements, external financing will be primarily debt-based.

Goldman Sachs credit strategists project that hyperscalers will fund 35% of their 2027 capital expenditure with debt, corresponding to approximately $400 billion in global bond issuance. Other AI infrastructure companies are also expected to seek additional financing.

Equity financing will play a supplementary role. For some companies, moderate equity issuance can help support multi-year investment plans while maintaining balance sheet quality and avoiding debt market capacity constraints.

Goldman Sachs Conclusion: Issuance is a Headwind, Not a Storm

Goldman Sachs' chief US equity strategist summarizes that equity issuance is a "manageable headwind, not a market hurricane."

The increase in follow-on offerings is primarily driven by AI financing needs, which are expected to persist. However, issuance is concentrated, the ratio of issuance to market capitalization remains below the long-term average, and neither issuance discounts nor post-announcement stock performance indicate signs of market indigestion.

Debt will bear the majority of external financing for hyperscalers and AI infrastructure investments, while the projected $1.4 trillion in stock buybacks will far exceed the approximately $700 billion in primary issuance and potential supply from lock-up expirations.

John Flood's assessment is straightforward: "Corporate stock demand will continue to outweigh supply in 2026."
