In the high-stakes world of climate innovation, there is a recurring, uncomfortable truth: the technology required to save the planet is often ready long before the market is willing to pay for it. While innovation competitions like those hosted by the XPRIZE Foundation have successfully galvanized thousands of teams and billions in investment, a sobering reality persists. In 2025, the global durable carbon removal market contracted sharply in terms of diversity, with Microsoft accounting for roughly 90% of all purchases. Despite nearly 30 million tons of contracted removal, physical delivery remains a mere fraction of the 6 to 10 billion tons per year that climate scenarios suggest will be necessary by 2050.
David Babson, Executive Vice President of the Energy, Climate, and Nature domain at XPRIZE, describes this persistent bottleneck as a systemic "market failure." According to Babson, the pace of technological advancement is currently outstripping the appetite of the private sector to adopt these solutions at scale.
The Evolution of the "Grand Challenge" Model
Historically, grand challenges were designed to serve as a beacon, drawing academic researchers and scrappy startups into the light of global attention. The goal was simple: provide a cash prize to the team that could prove a technical concept worked under rigorous, real-world conditions.
However, as Babson notes, the traditional "non-dilutive" cash purse—a one-time payment for a technical milestone—is no longer sufficient. "A prize is not a substitute for the very necessary investments that governments make into basic research," Babson explains. "Where the prize is valuable is downstream: translating those technologies to market for scale."
To address this, XPRIZE has begun shifting its architecture toward "mixed purses." This model pairs traditional cash awards with market-making mechanisms, such as advance market commitments (AMCs), power purchase agreements (PPAs), or guaranteed offtake contracts. The goal is to provide winners not just with a trophy and a check, but with a guaranteed first customer.
Chronology of a Market in Transition
The recent trajectory of the carbon removal and wildfire sectors illustrates the volatility of these emerging markets.
- 2024: The carbon removal sector showed early promise, with roughly 800,000 tons of carbon captured and sequestered.
- April 2025: Mati Carbon, a startup focused on enhanced rock weathering, secured the $50 million XPRIZE grand prize. Their method—spreading crushed basalt on farmland—proved doubly effective by sequestering carbon while simultaneously improving soil health and crop yields.
- Late 2025: Data from CDR.fyi revealed that while contracted tons surged to nearly 30 million, the actual delivery of sequestered carbon stalled at approximately 450,000 tons. The market became heavily reliant on a single corporate benefactor: Microsoft.
- September 2025: XPRIZE concluded its Wildfire competition. Defense contractor Anduril Industries claimed the top spot for autonomous fire response, securing $1 million in prize money plus a bonus from Lockheed Martin.
Supporting Data: The Scale of the Gap
The disparity between current output and scientific necessity is stark. Scientists estimate that the world must reach a capacity of 6 to 10 gigatons of annual carbon removal by 2050 to avoid the most catastrophic effects of climate change. Current progress, while technically impressive, is nowhere near this "pace of necessity."
Furthermore, the "innovation gap" is visible across sectors. In biodiversity, the Limelight Rainforest team demonstrated the ability to survey 100 hectares of tropical forest in under 24 hours, identifying over 250 species. Yet, there is no standardized, global market for biodiversity credits. Without a price signal, the technology—however brilliant—remains an underutilized tool in the conservationist’s kit.
Official Perspectives and Market Tensions
Babson argues that the hesitation of the market is largely political. "If people could make money taking carbon out of the air and putting it underground, as opposed to only being able to make money taking it from underground and putting it in the air, we would be in a better place," he says.
The tension within XPRIZE’s portfolio—which funds both climate restoration and "healthspan" longevity research—highlights the existential debate over abundance versus limitation. Critics of the "abundance" model, such as author Michael Maniates, argue that sustainability requires strict consumption corridors. In contrast, Babson envisions a future where clean energy is so abundant that society can move beyond efficiency as its primary organizing principle. "If we had cheap, clean energy," he posits, "we could power indoor vertical farms that would spare millions of acres of agricultural land, allowing us to return that land to nature."
Implications for Future Policy and Investment
The implications of this "market failure" are profound. If the private sector is not willing to provide the necessary demand, the role of philanthropy and policy must change.
The Case for Subsidies
In the wildfire sector, the technology developed by defense contractors like Anduril is currently priced at a premium that cash-strapped rural fire districts cannot afford. Experts suggest that the only way to lower these costs is through "aggregator" business models where components of these systems are licensed to cheaper, more accessible platforms. However, reaching that stage requires someone to buy the first, expensive units—a clear call for government or philanthropic intervention.
Measurement as a Catalyst
Babson believes that measurement technology is the ultimate weapon against policy stagnation. "Once you can quantify an ecosystem’s value in real-time, it becomes a dereliction of duty for policymakers to slow-walk climate action," he argues. By providing the data, XPRIZE forces the hand of regulators who can no longer claim that climate impact is too abstract to regulate.
The "Mixed Purse" Future
As XPRIZE looks toward upcoming fusion energy competitions, the strategy is clear: the contest must be as much about supply chain development as it is about physics. By integrating AMCs and offtake agreements directly into the prize structure, XPRIZE hopes to turn competitors into durable, market-ready enterprises.
Conclusion: The Path Ahead
The path to a carbon-neutral society is not paved with inventions alone, but with the institutional mechanisms that allow those inventions to survive the "valley of death" between the laboratory and the marketplace. While grand challenges have succeeded in proving that the technology exists to address our most pressing climate and environmental threats, the final hurdle remains financial and political.
As the industry moves forward, the focus must shift from simply rewarding innovation to actively building the market infrastructure that enables it. Whether through the billion-dollar funds that Babson envisions or the broader integration of carbon drawdown requirements into energy projects, the goal remains the same: transforming climate-positive technologies from a philanthropic pursuit into a global economic imperative.
For the startups, researchers, and policymakers watching these developments, the message from the XPRIZE Foundation is clear: the tools for a sustainable future are ready. The challenge now is to create the demand that makes using them inevitable.
