WASHINGTON D.C: A rift between the Pentagon and its former top artificial intelligence provider, Anthropic, is rapidly reshaping the U.S. military's AI ecosystem, with smaller startups seeing a surge in demand, funding interest, and contract momentum.

In recent weeks, defense-focused AI firms say senior military officials and investors have approached them at a pace rarely seen before, as the U.S. Department of Defense moves to reduce reliance on a single vendor.

The shift follows the Pentagon's decision in March to classify Anthropic's products as a "supply-chain risk," triggering a breakdown in relations and a broader push to diversify AI suppliers. A judge later temporarily blocked the Pentagon's blacklisting of the company.

Startups, including Smack Technologies and EdgeRunner AI, say they have seen a marked change in engagement from the military and investors.

"We've seen a massive increase in demand from customers and the government to get AI solutions fielded since Anthropic was declared a supply-chain risk," said Tyler Sweatt, CEO of Second Front, which helps firms operate on secure Pentagon networks. "Our customers are turning to us as the Pentagon turns to them to deploy quickly in the wake of the Anthropic blowup."

For smaller firms, access to Pentagon contracts is a major milestone, often unlocking further government work and signaling credibility to commercial clients.

Andrew Markoff, co-founder and CEO of Smack Technologies, said his company had been invited to multiple meetings with military officials following the Anthropic fallout, with a focus on accelerating deployment timelines. "We want more, we want demos, let's talk about how we can move faster," he said, describing the Pentagon's outreach.

Tyler Saltsman, CEO of EdgeRunner AI, reported a similar experience. His company had been waiting over a year for a Space Force contract to be approved, but it was finalized within weeks of the Anthropic dispute becoming public. "I can't prove that the Anthropic drama sped this up," Saltsman said, "but I have a sneaky suspicion it did."

A Pentagon official said the department would continue to deploy advanced AI capabilities through partnerships with multiple industry players.

The urgency reflects a broader reassessment within the Defense Department.

A Pentagon technologist previously told Reuters that the fallout with Anthropic highlighted the risks of overdependence on a single AI provider and underscored the need for a more diversified supplier base.

The impact is already visible in specific programs. Smack Technologies secured a Marine Corps contract in March 2025 and delivered a prototype by October that compresses operational planning from months to about 15 minutes. Despite initial delays, progress has accelerated sharply since the Anthropic controversy.

Markoff said there was "very specific guidance and movement and energy" to push the system into production for combat use in 2026, more than a year ahead of earlier expectations.

The company has also seen increased interest from other branches, including the Navy, Air Force, and U.S. Special Operations Command.

EdgeRunner AI said engagement from the Navy has intensified, with meetings now taking place several times a week instead of monthly.

Both companies are now working to meet higher security classification standards required for sensitive military applications.

EdgeRunner said it had been told it could achieve IL-6 clearance, allowing access to secret and top-secret data, within three months, a process that typically takes 18 months or longer.

Saltsman said the acceleration reflects both pressure from Pentagon leadership to streamline procurement and the urgency created by the Anthropic situation.
