Drone Maker Swarmer Jumps Another 52% After Soaring 520% in Debut

Drone maker Swarmer shares jumped another 52.1% in premarket trading on Wednesday.

Swarmer shares skyrocketed as much as 700% on Tuesday, making the artificial intelligence drone software company’s debut the best trading by a US stock since Newsmax’s blockbuster entry nearly a year ago.

Shares of the Austin, Texas-based firm closed up 520% at $31 on Tuesday. The surge triggered multiple volatility-based trading halts, including one less than a minute after the stock opened and initially dropped more than 10%.

Swarmer sold 3 million shares for $5 each, which at the time valued the company at just over $60 million. The trading gave the company a market value of over $380 million, based on the outstanding shares listed in a US Securities and Exchange Commission filing.

The company generated just $309,920 in revenue for the year ended December 31, 2025, a roughly 6% decline from the same period a year earlier. Its profitability also worsened over that stretch, with the company reporting a loss of about $8.5 million, more than four times larger than its net loss in 2024.

Swarmer is a software company, and not a drone manufacturer. Drones powered by the company’s artificial intelligence technology enables them to deploy and coordinate drone swarms, like a bird flock, at scale. Its platform has been deployed in Ukraine with more than 100,000 real-world missions in active combat environment, since April 2024, according to it regulatory filing.

Swarmer’s opening-day rally comes as investors are weighing their bets on defense spending, as the industry is seeing an emergence of software-driven, autonomous, unmanned systems, reflecting a broader move in modern warfare toward low-cost weapons. US defense stocks are off to a strong start in 2026, extending last year’s stellar performance as geopolitical tensions ramp up and military spending rises globally.
