In the rapidly evolvingartificial intelligence (AI) infrastructure space, breakthroughs in model training and deployment can translate almost overnight into valuation shifts. On Oct. 8, CoreWeave (CRWV) dropped a major announcement, driving an 8.7% surge in shares with thelaunch of Serverless RL, a fully managed, autoscaling reinforcement-learning platform that promises to lower the barrier to entry for AI agents. Launched shortly after CoreWeave’s acquisition of OpenPipe,Serverless RL integrates RL tools with the Weights & Biases platform, leveraging CoreWeave’s AI cloud.
The move is bold, especially given the inherent complexities in RL training, variable workloads, straggler effects, and cost inefficiencies. CoreWeave claims the new service offers 1.4 times faster training and 40% lower costs versus local H100 GPU setups. If true, that could be a game changer.

So, does Serverless RL make CRWV stock a buy now? Or is this just another feather in the cap of an already hyped stock? Let’s dig deeper.
Based in Livingston, New Jersey, CoreWeave was founded in 2017 and has transformed from its roots in cryptocurrency mining into a top-tier provider of GPU-optimized cloud infrastructure for AI training and inference. With a current market capitalization of about $66.9 billion, the company continues to expand its presence in the rapidly growing AI infrastructure market.
Sincegoing public in March 2025, CRWV stock has garnered intense investor interest, propelled by surging AI demand and high-profile partnerships with industry giants like OpenAI, Microsoft (MSFT), and Nvidia (NVDA). Shares of the company debuted at $40 and soared to a peak of $187 on June 20 amid investor enthusiasm for AI-related plays. However, the rally has since cooled, with CRWV stock closing at $127.06 on Oct. 20.
Nevertheless, over the past month, CRWV is up 2% amid renewed enthusiasm. Recent momentum appears to be driven by a confluence of positive catalysts in the AI infrastructure space.
CoreWeave has secured several marquee contracts that bolster its revenue visibility — most notably, a$14.2 billion deal with Meta Platforms (META) through 2031, which expands its client base beyond Microsoft and OpenAI. In September, CoreWeave also strucka $6.3 billion capacity-purchase agreement with Nvidia, which pledges to purchase any unused compute capacity through 2032, providing a demand backstop and reducing downside risk. Additionally, the firm expanded its existing relationship with OpenAI in September viaan up-to-$6.5 billion agreement, reinforcing its role as a critical backend for AI model training. Finally, on the product front, the launch of Serverless RL — which promises faster training and cost efficiency —is grabbing investor attention as a differentiating technological wedge.
