Why RUM stock is up today

RUM Group Inc A surged 14.57% to $8.22 in a single session driven by a reported $13.7 billion six-year compute deal with AI firm Anthropic. The stock opened with a 11.0% gap up and reached an intraday high of $8.65 before settling at $8.22. The move followed multiple reports identifying Anthropic as the previously undisclosed client behind a major computing contract disclosed by RUM in August.

What Happened

The stock's sharp rise was fueled by media reports linking RUM to a high-profile AI customer. Anthropic, a major AI research company, is reportedly the client behind the $13.7 billion contract. This revelation came after RUM had previously announced a significant computing deal in August without disclosing the identity of the client. The deal is expected to bolster RUM's AI cloud infrastructure ambitions and has drawn attention from both retail and institutional investors. The stock traded as high as 28% in premarket trading before settling into its current range.

What The Data Shows

The stock opened at $7.96 and traded as high as $8.65, with volume reaching 12.9 million shares, or 3.6 times the 3-month average. The price trend over the past eight sessions had seen a 12.7% decline from $8.80 to $7.68, making the current move a sharp reversal. RUM is currently trading within its 52-week range of $4.62 to $10.60. The stock also printed one fresh 52-week low and seven 52-week highs on September 14, 2026. Retail traders on social platforms have highlighted the deal as a major catalyst, though no official confirmation has been issued by the company.

What To Watch

RUM has not scheduled earnings in the near term. Investors should monitor the breadth of coverage and whether the company issues a formal statement confirming the reported Anthropic deal.
