CoreWeave's institutional ownership expands to 1,125 holders, nearing $40 billion
CoreWeave's institutional investor count increased to 1,125, with institutional ownership at 75.8% and total institutional investment reaching $39.7 billion, according to 13F filings for the quarter ended June 30, 2026. Magnetar Financial and Nvidia are the largest holders, with positions valued at roughly $5.2 billion and $4.7 billion. The former Ethereum miner, now an AI cloud provider, has a market capitalization between $45 billion and $50 billion and shares trading between $80 and $90.
CoreWeave began in 2017 as Atlantic Crypto, mining Ethereum before shifting its GPU resources toward AI computing. It listed on March 28, 2025, and reported about $5.13 billion in fiscal 2025 revenue. In October 2026, it partnered with AdaniConneX on a 240 MW AI data center in Navi Mumbai, India, expected to start initial operations in mid-2028.
13F filings for the quarter ending June 30, 2026, show institutional ownership between 72.5% and 75.8%, depending on methodology, with some counts exceeding 1,155 reporting institutions. Total institutional investment reached $39.7 billion. Magnetar Financial held roughly 9.45%–9.88%, valued near $5.2 billion, while Nvidia held about 8.57%–8.96%, worth near $4.7 billion.
CoreWeave’s heavy institutional backing may concentrate influence among large asset managers and Nvidia, potentially shaping AI compute access and pricing. Businesses relying on rented GPUs could see availability and costs affected by ownership shifts. The planned India data center may bring jobs and infrastructure, while also raising local questions about energy and land use. Retail investors could face sharper price swings when major holders adjust stakes.
