Company Overview

The world's most valuable private company

OpenAI's flagship ChatGPT — launched November 2022 — is the fastest-growing consumer application in history, serving 700+ million weekly consumer users. Together with the OpenAI API platform, GPT-5, the o-series reasoning models, and Codex for coding, its models power the largest enterprise AI deployments across Microsoft (Copilot, Azure), Apple (Apple Intelligence), Broadcom, IBM, HP, and thousands of Fortune 500 organizations. Approximately 40% of revenue now comes from enterprise, with parity to consumer targeted by year-end 2026.

OpenAI generates approximately USD 2 billion in revenue per month (USD 24+ billion run-rate as of Q1 2026, up from USD 13.1 billion in 2025) — growing four times faster than Alphabet and Meta did at comparable stages. The company benefits from a compute moat unmatched at scale: Microsoft's USD 100+ billion Azure commitment (through 2032), Amazon's USD 50 billion investment tied to AWS deployment, NVIDIA's USD 30 billion investment and preferred GPU allocation, plus the Broadcom "Jalapeño" custom AI chip announced June 2026.

Following the March 2026 conversion to OpenAI Group PBC and Sam Altman's announcement of "the third phase of OpenAI" — enterprise focus, coding assistants (Codex), and disciplined cost management — OpenAI confidentially filed for an IPO with the SEC on May 22, 2026 (Goldman Sachs, Morgan Stanley leading), with a potential Q4 2026 debut.

Valuation Development

From $14B to $852B —
and confidentially filed for IPO

OpenAI's last primary financing valued the company at USD 852 billion (March 2026 — USD 122 billion raised, the largest private fundraise in history). Lifetime capital raised now exceeds USD 180 billion; with a Q1 2026 run-rate of ~USD 24 billion, the current valuation implies a ~35x annualized revenue multiple.

Assessment

Opportunities & Risks

Opportunities

  • Largest potential IPO in history: confidentially filed May 22, 2026 with Goldman Sachs and Morgan Stanley; Q4 2026 or 2027 target.
  • Hyper-scaling revenue: USD 13.1B (2025) → USD 24B run-rate (Q1 2026) — growing 4x faster than Alphabet/Meta at comparable stages.
  • Enterprise inflection: 40% enterprise share targeted for parity with consumer by year-end 2026; Codex competing directly with Anthropic Claude Code.
  • Tri-hyperscaler compute moat: Microsoft USD 100B+ Azure, Amazon USD 50B AWS, NVIDIA USD 30B GPU allocation, Broadcom "Jalapeño" custom chip (June 2026) — multi-vendor redundancy.
  • Category-defining brand: ChatGPT is the fastest-growing consumer application in history (700M+ weekly active users) — brand advantage no competitor can replicate.
  • Institutional cap-table depth: record-broad investor base including SoftBank, Microsoft, NVIDIA, Amazon, a16z, Thrive, D.E. Shaw, ARK — plus USD 3 billion from individual investors via bank channels for the first time.
  • Ecosystem partnerships: Apple (Apple Intelligence), Broadcom, IBM, HP, Stripe (Agentic Commerce Protocol) — deepening embedded AI positioning.
  • Musk lawsuit resolved: May 18, 2026 dismissal removes major litigation overhang ahead of IPO.

Risks

  • Anthropic overtake: Anthropic reached USD 965 billion valuation in June 2026, surpassing OpenAI; enterprise API growth reportedly faster than OpenAI.
  • Frontier-model commoditization: Bridgewater's Greg Jensen (April 2026) called this "the biggest unpriced risk in the round"; open-source (Meta Llama, DeepSeek) closing the quality gap.
  • Not yet profitable: despite USD 24 billion revenue run-rate, OpenAI is not profitable and continues heavy compute investment.
  • USD 1 trillion compute plan risk: compute commitments require sustained access to capital markets; interest-rate or AI-market shifts could materially impact execution.
  • Corporate structure complexity: capped-profit + public benefit corporation structure creates governance ambiguity for public-market investors.
  • Talent poaching: Anthropic, xAI, Google DeepMind, Meta, Bezos-backed Prometheus offering USD 100M+ packages to OpenAI researchers.
  • Microsoft concentration risk: Microsoft owns ~27% of OpenAI and controls Azure exclusivity through 2032 — largest single dilution factor for new investors.
  • IPO timing risk: May 2026 SEC filing suggests Q4 2026 or 2027 IPO; delayed listing extends holding period for secondary investors.
  • Regulatory scrutiny: ongoing global AI regulation (EU AI Act, U.S. AI Safety rules); Musk lawsuit dismissed May 2026 but reputational overhang.
  • Structural & FX risk: indirect exposure via structured bond; USD currency risk; total loss possible.

Risk Notice

This product is intended exclusively for professional clients as defined by MiFID II. Buyers of a bond assume a significant risk, which can lead to the complete loss of the invested capital. The information provided here is non-binding promotional material and, in its nature and form, expressly does not constitute financial or any other investment advice. The information mentioned in no way replaces investment advice tailored to the investor's circumstances. The issuer expressly points out the following facts: Only the information provided in the issuer's offering documents (Cometum Direct Invest GmbH & Co. KG), i.e., the terms and conditions of the bond and the risk notice, are decisive for the assessment of the bond. None of the information constitutes an invitation to submit an offer to purchase, nor is it an offer to subscribe to or buy the issuer's bond. Cometum is not a bank, but solely an issuer and product provider for exclusive private markets products. This investment does not involve the direct acquisition of OpenAI shares by the investor, but rather a structured participation that allows participation in the value development of OpenAI. The information regarding the current valuation of OpenAI serves informational purposes only. The valuation at which structured participation in OpenAI takes place may differ from the current market valuation. It does not indicate an indicative entry price from Cometum. The company operates in a highly competitive market environment characterized by regulatory developments and geopolitical uncertainties. The strategic focus is on technology-oriented clients who require innovative solutions and high adaptability. Cometum participates directly or indirectly through one or more investments in special purpose vehicles, which in turn are directly involved with OpenAI. The OpenAI bond is therefore an entrepreneurial investment with risks. In principle, a total loss of the invested capital cannot be ruled out. The shares of OpenAI Inc. are quoted in the foreign currency US Dollar ("USD"). Therefore, in addition to customary market price fluctuations, they are also subject to exchange rate risk. Changes in the exchange rate between the euro and the USD can affect the performance and the euro-denominated return of the investment both positively and negatively. An appreciation of the euro against the USD may lead to losses, even if the price of OpenAI shares in their home currency, USD, has risen. Additional fees may apply at underlying participation levels (management fees, performance fees, exit fees, fees in connection with an IPO). The exact number of OpenAI shares outstanding is not necessarily publicly known or fixed at the time of investment. OpenAI may issue additional shares — for example in connection with its IPO, the financing of an acquisition, further financing rounds, or employee participation programmes. Such issuances dilute existing holders: the total number of shares increases, and the proportion of the company attributable to each existing share decreases accordingly. As a result, the valuation at which the structured participation was entered may, in retrospect, prove higher relative to the effective per-share basis and may change to the investor's disadvantage. In particular, the total valuation of the company may increase while the value attributable to an individual share — and therefore to the investor's participation — does not increase to the same extent, or may even decline. The headline valuation figures stated in this material are therefore not a reliable indicator of the value development of the investor's participation, which depends on the per-share value at the relevant point in time. This presentation is a non-binding offer (invitatio ad offerendum) and is for informational purposes only.
