Rumble (NASDAQ: RUM) stock climbed 10% to $7.87 in early Monday trading after a media report identified AI lab Anthropic as the customer behind its six-year compute contract.

The contract, valued at $13.7 billion over six years, was disclosed by Rumble in an August securities filing that left the customer unnamed, and neither company has confirmed the reported pairing.

According to the media report, the arrangement would allow Anthropic to acquire up to 51 million Rumble shares at $0.01 each, tying the customer’s incentives directly to the equity.

The compute capacity is expected to originate from a Rumble data center in Maysville, Georgia, which remains under construction and has not yet reached operational status.

The rally is hitting rented-compute rivals hard on the same tape, with CoreWeave (NASDAQ: CRWV) falling 9% to $81.25 and Nebius Group (NASDAQ: NBIS) declining 9% to $205.28, extending recent weakness across the group.

The reported Anthropic award is being read by the market as competitive share captured by Rumble directly at the expense of those established cloud infrastructure peers.

Broader benchmarks confirm the damage is concentrated in AI compute specifically, with the First Trust Cloud Computing ETF (NASDAQ: SKYY) down only 0.58% and the Invesco QQQ Trust (NASDAQ: QQQ) off 1.63%, leaving Rumble’s gain in sharp contrast.

Rumble entered AI infrastructure earlier this year by acquiring German cloud provider Northern Data in an all-stock transaction, and now operates its media platform alongside an AI infrastructure unit called Quake AI.

Rumble also provides cloud hosting services for Truth Social, the platform run by Trump Media and Technology Group (NASDAQ: DJT), adding another layer to its infrastructure business.

The same company sits at the center of both sides of Monday’s story, as Anthropic CEO Dario Amodei published an essay over the weekend calling on frontier AI firms to slow the pace of model capability development, with OpenAI CEO Sam Altman backing him publicly.

That essay has weighed on sentiment across the rented-compute complex, pressuring CoreWeave and Nebius even as the reported Anthropic contract lifts Rumble in the opposite direction.

The bull case for Rumble rests on the idea that a six-year commitment of this size converts a speculative cloud pivot into contracted revenue with structured equity upside attached.

The bear case centers on the report remaining unconfirmed, the Georgia facility still being under construction, and the financing plan behind the buildout remaining undisclosed to the market.

Rumble trades off a far smaller base than either CoreWeave or Nebius, which explains why a single unconfirmed media report can produce a double-digit move on a day when peers are being sold.

Investors should watch for official confirmation from either party, construction milestones at the Maysville facility, and any financing disclosure tied to the buildout, as all three will determine whether today’s move marks the beginning of a genuine rerating.

Rumble is also in the process of folding Northern Data results into its consolidated reporting, and the shape of that combined financial picture may set the next meaningful repricing window for the stock.

An official acknowledgment of the contract counterparty would revalue what the Northern Data acquisition contributes to the combined business and could pressure GPU cloud incumbents to disclose fresh customer wins in response.
