The Frontier coalition has added $915 million to its carbon removal fund, bringing in Anthropic as its newest member. The fresh cash and corporate backing could speed up the development of technologies that pull carbon dioxide out of the atmosphere.
Why the extra cash matters
Frontier, a group of companies that pool money to buy carbon removal credits, now has a total of over $1.8 billion committed since its launch in 2022. The latest $915 million tranche gives startups in the space a clearer signal that there's real demand for their services. Carbon removal tech — from direct air capture plants to enhanced rock weathering — has struggled to scale because it's still expensive and lacks a guaranteed market. Advance purchase commitments from Frontier and others help bridge that gap.
Anthropic's role
Anthropic, the AI company behind the Claude chatbot, was added to the coalition's roster. The company didn't disclose how much it contributed, but its presence expands the coalition beyond its original members — Stripe, Shopify, and others. Anthropic has been vocal about the energy demands of AI and the need to offset its carbon footprint. Joining Frontier fits that goal.
What the money will buy
The coalition uses the funds to sign off-take agreements with carbon removal startups. That means a company like Climeworks or Charm Industrial gets paid for every ton of CO₂ it captures and stores, even if the process isn't yet profitable at scale. The new funding extends the coalition's buying power through 2025 and beyond. Members can also use the credits to meet their own net-zero targets.
The unresolved question
Carbon removal still faces a long road to commercial viability. The cost per ton can run hundreds of dollars, far above what most polluters pay to emit. Frontier's latest round buys time for the technology to mature, but it's not clear how quickly costs will fall — or whether governments will step in with their own purchases. The coalition's next moves will be watched closely by the startups that depend on its checks.
