SB Energy, the SoftBank Group–controlled developer of a massive planned Ohio data center project for OpenAI, is considering going public in December or possibly waiting until next year, according to people familiar with the discussions.

That is a later timeline than previously expected. The data center developer was aiming to go public as soon as September, The Information reported in August. But since then, the public market has soured on initial public offerings from data center and AI cloud companies. Australian cloud firm Firmus yanked its IPO plans earlier this month, and others are considering delaying their offerings.

Enterprise software firm Datadog recently offered to buy cloud cybersecurity startup Upwind Security for nearly $4 billion, the latest sign of white-hot interest in such firms, according to someone with direct knowledge of the talks.

Upwind, which hasn’t accepted the offer, is finalizing a $300 million funding round at a roughly $3.8 billion valuation, meaning the offer doesn’t carry much of a premium over the private valuation, said two people with knowledge of the situation. The startup sells software to keep tabs on applications, including so-called AI agents, that run in the cloud and to detect and automatically respond to potential evidence of hacks or breaches.
