OpenAI Targets September IPO with Goldman Sachs and Morgan Stanley Mandated as AI-Linked Convertible Bond Issuance Hits Record Pace

OpenAI, last valued at $852 billion, is preparing to confidentially file for a US initial public offering (IPO — a company's first sale of shares to the public) within weeks, aiming to go public as early as September 2026. Goldman Sachs and Morgan Stanley are working with the company on a draft IPO prospectus for submission to securities regulators. The move comes just days after OpenAI successfully defended an existential legal challenge brought by Elon Musk and follows a $122 billion funding round earlier this year — widely reported as Silicon Valley's largest-ever private fundraising. The planned filing also threatens to overshadow a separate IPO by Musk's SpaceX, which was expected to file around the same period. OpenAI has revised its product roadmap twice in recent months amid intensifying competition from Google and Anthropic, with some analysts projecting Anthropic's revenue growth could surpass OpenAI's within months. The IPO landing in this macro environment is notable: US convertible bond (debt that can be converted into equity) issuance reached approximately $34 billion in the first four months of 2026, more than double the same period a year earlier, with roughly half tied to AI-linked capital expenditure. That surge is itself a signal of how investor appetite for AI-sector equity exposure is driving record debt-market activity — a context that will shape OpenAI's bookbuilding and valuation expectations if it proceeds to a public listing.

UK CCS Project Finance Pipeline Building

The fabrication milestone on Aquaterra Energy's RAF system for the Northern Endurance Partnership marks a concrete step toward the East Coast Cluster CCS infrastructure reaching financial close. With the UK government treating industrial decarbonisation as a strategic priority, lawyers with energy project finance and carbon storage licensing expertise are positioned for a sustained pipeline of mandates. The North Sea Transition Authority's oversight of offshore CO₂ storage licensing, combined with the complex inter-creditor arrangements needed for CCS project finance, means that both contentious and non-contentious energy practices will see activity. Watch for formal investment decisions on East Coast Cluster projects in H2 2026 as technical milestones convert into bankable documentation.

OpenAI's confidential IPO filing with Goldman Sachs and Morgan Stanley as bookrunners — targeting a September 2026 listing at an $852 billion valuation

The prospectus verification and risk disclosure process for a company that has revised its product roadmap twice in months, faces active competition from Anthropic and Google, and recently survived a major legal challenge will be one of the most complex ECM instructions of the decade — generating work across capital markets, litigation risk disclosure, and corporate governance practices simultaneously. City ECM and securities law teams should monitor for the public filing, which will set valuation and disclosure benchmarks for every European AI company considering a listing.
