OpenAI IPO Talks With JPMorgan, Citigroup Signal Blockbuster Listing

OpenAI has initiated preliminary discussions with JPMorgan Chase & Co. and Citigroup Inc. to lead its initial public offering preparations, according to a report on May 29, 2026. The move signals a major step toward a public listing for the artificial intelligence leader, which industry analysts project could achieve a valuation well above $100 billion. JPMorgan stock traded at $299.31 while Citigroup shares were at $125.90 as of 21 UTC today, reflecting modest daily gains of 0.01% and 0.41% respectively amid broader market calm.

Context — [why this matters now]

Selecting lead underwriters is a critical first formal step in the IPO process, establishing the banking syndicate that will manage valuation, regulatory filings, and investor roadshows. This development occurs against a backdrop of renewed investor appetite for high-growth technology listings, with the Nasdaq Composite Index showing sustained strength year-to-date. The AI sector specifically has seen a surge in both private funding rounds and public market valuations, driven by continued enterprise adoption of generative AI tools. OpenAI’s move follows its latest funding round, which reportedly valued the company at over $80 billion, making a potential public offering one of the largest in technology history.

The selection of traditional bulge bracket banks like JPMorgan and Citigroup, rather than tech-focused underwriters, suggests OpenAI prioritizes global distribution capability and stability. This mirrors the approach taken by other mega-cap technology listings, including Facebook's 2012 IPO which was led by Morgan Stanley, JPMorgan, and Goldman Sachs. The current IPO market has shown particular strength for companies with demonstrable revenue growth and a path to profitability, criteria that OpenAI is expected to meet given its substantial enterprise revenue from ChatGPT and API services.

Data — [what the numbers show]

JPMorgan shares traded within a daily range of $295.23 to $299.60 before settling at $299.31, representing a negligible single-day move of just 0.01%. Citigroup demonstrated slightly stronger performance, gaining 0.41% to close at $125.90 after touching a high of $126.84 during the session. Both stocks have significantly outperformed the broader financial sector ETF (XLF) year-to-date, with JPMorgan up approximately 18% and Citigroup gaining 22% compared to XLF's 12% advance.

The investment banking fee pool for U.S. IPOs reached $8.2 billion in 2025, with top underwriters typically capturing 4-7% of the total proceeds raised. A hypothetical $100 billion OpenAI IPO could generate underwriter fees between $4 billion and $7 billion, distributed among the lead banks and syndicate members. This would represent the largest technology underwriting fee since the $100 billion Saudi Aramco listing in 2019. JPMorgan currently holds the top position in global IPO league tables with a 9.3% market share, while Citigroup ranks fifth with a 6.1% share.

Analysis — [what it means for markets / sectors / tickers]

The involvement of JPMorgan and Citigroup provides immediate credibility to OpenAI's public market ambitions, likely creating positive sentiment across the artificial intelligence ecosystem. Publicly-traded AI infrastructure companies like NVIDIA, Advanced Micro Devices, and Super Micro Computer may see increased investor interest as markets price in a successful IPO. Secondary beneficiaries include cloud providers Microsoft Azure, Google Cloud, and Amazon Web Services, which host and partner with large AI models.

A counter-argument exists that current AI valuations incorporate optimistic assumptions about enterprise adoption rates and monetization, creating execution risk for any new issuance. The success of recent AI-related IPOs has been mixed, with some hardware-focused names struggling post-listing despite initial enthusiasm. Hedge funds and venture capital firms that hold private shares in OpenAI competitors are likely increasing their hedging activity in public AI proxies, creating additional trading volume in names like Snowflake and Databricks.

Outlook — [what to watch next]

Market participants should monitor official SEC filing activity for OpenAI's S-1 registration statement, which would provide the first detailed look at financial performance and ownership structure. The timing of the IPO will likely depend on equity market conditions in the second half of 2026, particularly the performance of recent technology listings. Key technical levels for AI sector sentiment include the Nasdaq 100 Index maintaining support above 21,000 and the Global X Robotics & Artificial Intelligence ETF (BOTZ) holding its 200-day moving average.

Future catalysts include Federal Reserve policy decisions on interest rates, which affect growth company valuations, and quarterly earnings reports from major cloud providers that demonstrate AI revenue contribution. The composition of the full banking syndicate will also be telling—whether OpenAI adds more technology-focused underwriters or maintains a traditional banking group. Valuation estimates will crystallize after investor roadshows, with preliminary range expectations likely emerging 30-60 days before the anticipated listing date.

Frequently Asked Questions

What banks are leading the OpenAI IPO?

JPMorgan and Citigroup are reportedly in talks to lead OpenAI's initial public offering preparations. These bulge bracket banks bring extensive experience with large-scale technology listings and global distribution networks that can handle what may become one of the largest IPOs in history. The selection process typically involves multiple banks pitching for lead left position, which carries the highest fee allocation and prestige.

How does OpenAI's potential valuation compare to other tech IPOs?

Analyst projections suggesting a valuation exceeding $100 billion would place OpenAI among the largest U.S. technology IPOs ever. This would surpass Meta's (then Facebook) $104 billion valuation at its 2012 debut and approach the scale of Saudi Aramco's $256 billion 2019 offering. Unlike many recent technology listings, OpenAI already generates substantial revenue from its enterprise products and API services.

What does OpenAI going public mean for AI stocks?

A successful OpenAI IPO would likely create a positive halo effect across the artificial intelligence sector, validating current valuations and attracting more capital to the space. Public comps would provide valuation benchmarks for private AI companies and could accelerate IPO plans for other well-funded AI startups. Established technology companies with significant AI exposure might also benefit from increased investor attention and valuation multiples.

Bottom Line

OpenAI's banking selection signals the beginning of a landmark technology listing process that will test public market appetite for artificial intelligence valuations.
