SB Energy files for IPO, substantially dependent on OpenAI
SB Energy, an AI power infrastructure company backed by Softbank, OpenAI, and Nvidia, has filed for an IPO with the U.S. SEC. The company plans to list on Nasdaq under ticker SBE and is seeking to raise between $5 billion and $7 billion. It has not yet generated revenue from its data center business, with none operational, and incurred net losses of approximately $3.2 billion in the first half of 2026. Nvidia has committed $105 billion in financing for an OpenAI data center in Ohio to be built by SB Energy. The filing highlights significant dependence on OpenAI as both a tenant and equity investor, along with risks including community backlash against data centers.

OpenAI Files Confidential S-1 for IPO
OpenAI filed a confidential draft registration statement with the U.S. Securities and Exchange Commission to pursue an initial public offering, the company announced on 2026-06-08. The move follows rival Anthropic’s recent IPO filing and intensifies a high-profile race to the public markets that also includes SpaceX. OpenAI was last reported valued at $852 billion post‑money and in late March raised $122 billion in a funding round (including $3 billion from retail investors). The company has signalled large future compute and cash‑burn projections (including plans to spend roughly the same amount on computing power in 2028 and an $85 billion projected burn in that year). The filing discloses no share count or price guidance. The announcement comes amid internal governance history and multiple lawsuits involving OpenAI and its leadership.
OpenAI Flags Microsoft Reliance in IPO Risk Filing
OpenAI circulated an investor document resembling an IPO prospectus that warns its close ties to Microsoft — which provides a substantial portion of its financing and compute — could pose a risk to the business. The filing-style document, shared with prospective investors tied to a recent financing, also cites large capital expenditures, heavy compute needs, supply‑chain vulnerability to TSMC disruptions, ongoing litigation (including multiple suits from Elon Musk/xAI and at least 14 user-filed cases), and its atypical public benefit corporation structure as material risks. The company recently announced $110 billion in strategic funding from partners including Amazon, Nvidia and SoftBank and is seeking an additional ~$10 billion; it reported $13.1 billion revenue in 2025, ~900 million weekly active ChatGPT users, and a valuation of about $730 billion. OpenAI disclosed roughly $665 billion of estimated compute spend commitments through 2030.
Nvidia Eyes $250B Backstop for OpenAI Data Center
The author argues that recent large-scale, off‑balance-sheet financing in the GenAI sector is increasingly viewed with skepticism. He recalls Oracle’s September 2025 $300 billion data-deal with OpenAI and the subsequent stock volatility, and reports that Nvidia is reportedly considering a $250 billion financing backstop for an OpenAI-led data center project (reportedly tied to a SoftBank Ohio 10GW lease). Markets reacted negatively to the Nvidia news, with early trading showing a notable drop in Nvidia shares. The piece highlights wider market wariness, creditor concern, and the broader idea of “circular” or “creative” financing sustaining the GenAI boom rather than profits.
