Rumble stock jumped 10% Monday after a media report named Anthropic as the customer behind Rumble's $13.7 billion six-year compute contract. CoreWeave and Nebius Group each fell 9% on the same tape, as an essay from Anthropic's CEO calling for slower AI development pressured rented-compute peers.
Rumble (NASDAQ:RUM) rose 10% to $7.87 in early Monday trading after a media report tied AI lab Anthropic to the six-year compute contract Rumble disclosed in an August securities filing. Neither company has confirmed the pairing, but the reaction on Rumble stock has been immediate.
CoreWeave and Nebius drop on the same tape
The move is punishing rented-compute peers. CoreWeave (NASDAQ:CRWV) fell 9% to $81.25. Nebius Group (NASDAQ:NBIS) declined 9% to $205.28, and the reported award reads as competitive share captured by Rumble at the peers' expense.
The First Trust Cloud Computing ETF fell 0.58%. The Invesco QQQ Trust dropped 1.63%, with damage largely concentrated in AI-compute names rather than spread across cloud software.
The reported Anthropic deal
According to the report, the customer behind Rumble's $13.7 billion contract is Anthropic, and the arrangement reportedly lets Anthropic acquire up to 51 million Rumble shares at $0.01 each. Rumble left the customer unnamed in August, and the capacity is expected to come from a Maysville, Georgia data center still under construction. Rumble entered AI infrastructure earlier this year by acquiring German cloud provider Northern Data in an all-stock deal, and now runs its media platform alongside an AI infrastructure unit called Quake AI. It also hosts Truth Social, operated by Trump Media & Technology Group.
Amodei essay weighs on peers
Anthropic CEO Dario Amodei published an essay over the weekend calling on frontier AI firms to slow the pace of model capability development, and OpenAI CEO Sam Altman backed him. That call is pressuring CoreWeave, Nebius and the wider rented-compute complex even as the reported Anthropic contract lifts Rumble.
The bull case is that a six-year commitment of this size converts a speculative cloud pivot into contracted revenue, with a deep-in-the-money share option tying the customer's incentives to the equity. The bear case: the report is unconfirmed, the Georgia site is still being built, and the financing plan behind the buildout isn't yet visible. Investors can watch for confirmation from either party, construction milestones at Maysville, and financing detail, since those will determine whether Monday's move holds.
