Palantir Technologies was the top-performing stock in the S&P 500 and Nasdaq-100 during the first half of 2025. With shares soaring by 80% through the first six months of the year — and by 427% over the last 12 months — Palantir has helped drive a lot of attention to the intersection of artificial intelligence (AI) and defense contracting.

Palantir is far from the only company seeking to disrupt defense tech. A little-known competitor to the company is BigBear.ai (BBAI -3.35%), whose shares are up by an impressive 357% over the last year.

Could BigBear.ai emerge as the next Palantir? Read on to find out.

BigBear.ai is an exciting company in the world of defense tech, but…

BigBear.ai’s share price volatility so far this year mimics the movements of a rollercoaster. Initially, shares rose considerably shortly following President Donald Trump’s inauguration and the subsequent announcement of Project Stargate — an infrastructure initiative that aims to invest $500 billion into AI projects through 2029.

However, these early gains retreated following the Pentagon’s plans to reduce its budget by 8% annually.

While reduced spending from the Department of Defense (DOD) was initially seen as a major blow to contractors such as Palantir and BigBear.ai, the trends illustrated above suggest that shares rebounded sharply — implying that the sell-offs back in February may have been overblown. Why is that?

In my eyes, a major contributor to the recovery in defense stocks came after Defense Secretary Pete Hegseth announced his intentions to double down on a strategy dubbed the Software Acquisition Pathway (SWP).

In reality, the DOD’s budget cuts are focused on areas that are deemed non-essential or inefficient. For example, the Pentagon freed up billions in capital by reducing spend with consulting firms such as Booz Allen Hamilton, Accenture, and Deloitte. In addition, a contract revolving around an HR software system managed by Oracle was also cut.

Under the SWP, it appears that the DOD is actually looking to free up capital in order to double down on more tech-focused initiatives and identify vendors that can actually handle the Pentagon’s sophisticated workflows.

With so much opportunity up for grabs, it’s likely that optimistic investors saw this as a tailwind for BigBear.ai. This logic isn’t too far off base, either.

BigBear.ai’s CEO is Kevin McAleenan, a former government official with close ties to the Trump administration. McAleenan’s strategic relationships within the government combined with the DOD’s focus on working with leading software services providers likely has some investors buying into the idea that BigBear.ai won’t be flying under the radar much longer.

…how does the company really stack up beside Palantir?

The graph below breaks down revenue, gross margin, and net income for BigBear.ai over the last year. With just $160 million in sales, the company tends to generate inconsistent gross margins — which top out at less than 30%. Moreover, with a fairly small sales base and unimpressive margin profile, it’s not surprising to see BigBear.ai’s losses continue to mount.

By comparison, Palantir generated $487 million in government revenue during the first quarter of 2025. In other words, Palantir’s government operation generates nearly triple the amount of revenue in a single quarter that BigBear.ai does in an entire year. On top of that, Palantir’s gross margins hover around 80%, while the company’s net income over the last 12 months was over $570 million.

Is BigBear.ai stock a buy right now?

Right now, BigBear.ai trades at a price-to-sales (P/S) ratio of around 11. While this may look “cheap” compared to Palantir’s P/S multiple of 120, there is a reason for the valuation disparity between the two AI defense contractors.

Palantir boasts large, fast-growing public and private sector businesses that command strong profit margins. By contrast, BigBear.ai is going to have a difficult time scaling so long as it keeps burning through heaps of cash.

Not only would I pass on BigBear.ai stock, but I also do not see the company becoming the next Palantir. Palantir is in a league of its own in the defense tech space, and I do not see BigBear.ai as a formidable challenger.

Microsoft has just signed a deal with Vaulted Deep, paying it to remove 4.9 million metric tons of waste over 12 years sourced from manure, sewage, and agricultural byproducts for injection deep underground. According to Inc., the current cost of CO2 removal with the company is $350 per ton. If you multiply that by Microsoft’s contract, that makes it worth more than $1.7 billion. However, neither entity has disclosed the actual terms of the deal, and its CEO, Julia Reichelstein, says that the company expects its costs to drop over time, and that the mentioned price isn’t the actual sum that the tech giant paid.

This isn’t the first time Redmond has paid another company to help offset its greenhouse gas emissions; Microsoft signed a deal with AtmosClear in April of this year to sequester 6.75 million metric tons of carbon dioxide. However, Vaulted’s technique is unique — instead of extracting carbon dioxide from the air or electricity production, it collects organic waste. It combines it into a thick slurry, which is then injected about 5,000 feet underground. This prevents them from being dumped at a waste disposal site, where they would eventually decompose and release carbon dioxide into the atmosphere.

Przemysław “Psyho” Dębiak, a 42-year-old programmer from Gdynia, Poland, made history by defeating OpenAI’s custom AI model at the AtCoder World Tour Finals (AWTF) 2025 “Humans vs AI” contest in Tokyo. Considered one of the most prestigious coding tournaments in the world, the AWTF invites just 12 of the top-ranked human programmers—and, for the first time, an AI competitor—to tackle its grueling challenges. After a 10-hour coding marathon, Dębiak edged out the AI by roughly 9.5%, clinching first place while the OpenAI-built model settled for second.

“Humanity has prevailed (for now)!” Dębiak wrote on X, confessing he’d slept only around 10 hours over three days while pushing himself to the limit. OpenAI CEO Sam Altman aptly responded with, “Good job, Psyho.” The AI model, branded OpenAIAHC, was widely expected to dominate the market. Still, Dębiak’s innovative, heuristic-driven approach—using problem-solving shortcuts and educated guesses instead of brute-force calculation—secured the win. Contest administrator Yoichi Iwata praised his distinctive method, noting that while the AI excelled at raw optimization, it “fell short of human creativity.”
