Accelevation, an AI power infrastructure company, is set to go public in a $2.8 billion U.S. IPO week.

Two sizable IPOs are scheduled for the week ahead. VC-backed smart ring maker Oura plans the largest consumer discretionary IPO in years, while PE-backed Accelevation will serve as a key test for the IPO market's AI infrastructure theme.

Oura (OURA) plans to raise $2.1 billion at a $15.0 billion market cap. Existing shareholders are selling 73% of the deal, with primary proceeds going to RSU-related tax withholding obligations. Oura sells a finger-worn sensor ring that tracks sleep, activity, stress, heart health, and women's health, paired with an app that turns the readings into more than 50 metrics and AI-generated guidance. Hardware accounted for 80% of revenue in the first nine months of fiscal 2026, with the remaining 20% from recurring membership subscriptions that unlock the full suite of health insights. As of June 30, 2026, it served 5.0 million paid members (up 100% year-over-year) across 56 markets worldwide, with 12-month paid member retention of approximately 85%. In a notable first, Robinhood is a co-manager on the offering, while Coinbase is a selling agent.

Power distribution products manufacturer Accelevation (ACCV) plans to raise $660 million at a $4.9 billion market cap. Owned by Stamford-based PE firm Olympus Partners, Accelevation primarily provides products and services to hyperscale, colocation, AI, cloud and other large-scale data center customers. Its products include branch circuit whips, remote power panels, PDUs and related monitoring, thermal management and field installation into factory-built packages. The company grew revenue 147% in 2025 and had a backlog of approximately $1.1 billion as of June 30, 2026.
