Explore stocks on Coinbase

Applied Digital (NASDAQ: APLD) and TeraWulf (NASDAQ: WULF) are two of the top AI stocks riding the data center wave. Both neocloud companies develop and operate facilities that serve hyperscalers, but their stock returns have been a little different this year.

TeraWulf is up by 36%, while Applied Digital has gained just 11%. Is that gap just a fluke, or is it a sign of things to come? Here's what investors should consider.

Applied Digital has the advantage with gigawatts

Gigawatts are the name of the game when it comes to analyzing neocloud and colocation providers that offer IT capacity to hyperscalers. The more gigawatts a company has, the more revenue it can make.

Applied Digital has secured 1.4 gigawatts of contracted critical IT load, which comes to roughly $36 billion in total contracted lease revenue. Most of these contracts have 15-year terms, including two deals for 300 megawatts at the company's Delta Forge 1 and Polaris Forge 3 sites.

TeraWulf only has 839 megawatts of leased capacity. Most of that came from a 20-year deal with Anthropic for $19 billion that covers 401 megawatts.

Neither of these companies is able to deliver all of this capacity yet. TeraWulf told investors that revenue from the Anthropic deal will start to materialize in the second half of 2027, while revenue generation across all 401 megawatts is expected by early 2028.

Applied Digital also has the bigger pipeline

Not only does Applied Digital have more contracted power, but it also has the bigger pipeline. Secured deals make it easier for neocloud and colocation providers to secure financing to build out their infrastructure, while pipelines increase the number of gigawatts, which can result in more lucrative contracts in the future. Further price improvements seem likely as demand for compute capacity continues to expand rapidly.

Applied Digital has an active pipeline of roughly 3 gigawatts, while TeraWulf's is about 2.1 gigawatts. These figures do not include power or land for which they are still in the early stages of discussion and due diligence, so the size of the gap between them could change quickly. Earlier in the year, TeraWulf announced the acquisition of a Kentucky site that exceeded 1 gigawatt. Another deal like that for Terawulf that could completely close the gap, while a similar deal for Applied Digital would meaningfully expand it.
