A massive deal several months in the making has closed with Tether saying Wednesday it led a Series C round worth up to $1.4 billion in the German tech startup Neura Robotics. 

"By supporting the raise of up to $1.4 billion from a diversified group of strategic and financial investors into Neura Robotics, the group takes a decisive step by backing a company redefining how machines think, move, interact, and transact with the physical world," Tether said in a statement.

The declaration comes several months after revelations surfaced that the stablecoin issuer was considering a major investment in the robotics firm last year.

Neura is developing a portfolio that includes robotic humanoids, precision arms, autonomous mobile robots, and service robots, according to Tether's statement. The robots will be built to "operate across every environment where human-machine collaboration creates real-world value."

Tether has become a prolific venture capital investor in recent years thanks to its highly profitable stablecoin business as the issuer of USDT. The firm keeps its stablecoin reserves in yield-bearing investments like U.S. Treasurys.

Besides the capital commitment, Tether said it will provide and "deploy" technology within the "Neura robotics ecosystem." That will include, according to the statement, Neura integrating Tether's Wallet Development Kit directly into robotic systems.

"To be truly autonomous, robots need financial tools," Tether said.

In January 2025, Neura raised nearly $140 million in a round that included investors such as BlueCrest, C4 Ventures, Lingotto, and Volvo Cars Tech Fund. Neura will be competing with Elon Musk's Tesla, which also aims to mass-produce robots.
