Analysis
Fort Robotics, a startup backed by Mark Cuban that builds safety infrastructure for autonomous machines, agreed to go public through a merger with Newbury Street II Acquisition Corp, valuing the combined company at roughly $557 million enterprise value, Bloomberg reported. The company describes the deal as making it the first publicly traded company principally focused on the safety of physical AI.
What Fort actually sells
Fort's mission, in its own words, is to "ensure robots cause no harm." Founded in 2018 by Samuel Reeves, who spent the prior decade working on landmine-clearance robotics before identifying a gap in secure machine-to-machine communications, the company's Trust Layer platform is safety infrastructure for autonomous machines operating across warehousing, transportation, manufacturing, construction, agriculture, mining, energy and defense -- industries where robots and humans increasingly share physical space. The platform combines functional-safety and cybersecurity principles so that critical commands and status information can move reliably to, from and between machines from different manufacturers. It's backed by 25 patents and certified to Safety Integrity Level 3 under IEC 61508, an established industrial-safety standard, not a self-defined benchmark.

In May 2026, Fort expanded the platform by acquiring Mapless AI, a full-stack, safety-first teleoperation company, adding remote human-in-the-loop control capability to its safety layer ahead of this listing.
The SPAC route, and why it fits this business better than a traditional IPO
Fort's path to public markets via SPAC rather than a traditional IPO is notable given how out of favor SPACs fell after the 2021-2022 wave of underperformance. A SPAC merger works better than a traditional IPO roadshow for a company like Fort precisely because its business -- safety-certification infrastructure sold to industrial and defense customers -- is a harder story to explain to public retail investors in a standard roadshow than a SPAC's negotiated, story-driven merger process allows. The physical-AI safety category is also genuinely new enough that there's no direct public comparable to benchmark a traditional IPO valuation against.
The category itself is the real thesis. As physical AI -- robots, autonomous vehicles, industrial automation -- scales into environments with humans, the question of who certifies these systems as safe, and who's liable when they aren't, becomes a real commercial and regulatory problem rather than a hypothetical one. Fort is betting that becomes a standalone infrastructure layer analogous to cybersecurity for enterprise software: not a feature any single robotics maker builds in-house, but a cross-manufacturer standard that becomes mandatory as insurers, regulators and enterprise buyers start requiring third-party safety certification before deploying autonomous machines at scale.
The risk in that thesis is timing. $557 million values a genuinely early-stage safety-infrastructure category on the assumption that mandatory third-party certification becomes standard practice across robotics and industrial automation within a reasonable investment horizon. If regulators and insurers move slowly -- which has historically been the norm in industrial safety standards -- Fort's addressable market stays smaller and more fragmented than the valuation implies for longer than public investors typically tolerate.
