Deep Tide Introduction: A quantitative investment thesis written by the founder of Aave himself: He calculates the capital expenditures for solar energy, data centers, robotics, nuclear energy, and space infrastructure one by one, concluding that the real market size facing DeFi is $100-200T, which is 15 times the total assets under management of the world's top ten banks. Whether the argument holds or not is another matter, but this analytical framework is worth a careful read for everyone following the RWA sector.
Full text as follows:
I previously wrote that DeFi has already improved the supply side of the capital allocation problem. On-chain liquidity is highly fluid and can be programmatically shifted to opportunities with higher risk-adjusted returns. Aave has demonstrated its ability to absorb hundreds of billions of dollars in liquidity, thanks to the trust it has built over the years and the superior cost structure it provides through the crypto-collateralized lending model.
This liquidity creates enormous opportunities for the emerging financial primitives and use cases. The next evolution of DeFi should focus on the demand-side problem, rebalancing the liquidity equilibrium.
I also previously wrote that solar energy infrastructure alone could present a $30-50T opportunity for Aave. But this is far from the end; the future opportunities Aave can tap into exceed $200T.
The Infrastructure That Powers Everything, The Finance That Funds Everything
The bottom layer that makes everything run is infrastructure. This layer ensures our electric vehicles have range to drive, our homes stay warm and lit, water flows normally, computers can compute, and the world stays connected.
From a capital allocation perspective, infrastructure is seen as a safe choice. The world needs energy, water, computing power, and communication. Established infrastructure also carries technology risk that decreases over time and with scale benefits, gradually shifting from a technology opportunity to a financial opportunity as it matures.
Although considered stable and safe, emerging infrastructure also offers strong allocation opportunities with higher returns. The technology is early on the cost curve, and the risk premium is correspondingly richer.
Infrastructure (the right kind) is a high-quality product for finance because it typically involves high capital expenditures that require financing and low operational expenditures—meaning operational costs are low enough that debt can be repaid over the asset's lifecycle. From many perspectives, infrastructure financing for the future consists of hard assets with cash flows.
Most importantly, when structured correctly, infrastructure finance follows Aave's lending model—loans are made against the asset itself, not the user's credit, similar to how Aave operates today.
How Big is the Opportunity?
I believe the infrastructure assets crucial for the world's transition to abundance include: solar farms, batteries, data centers and GPUs, electrified transportation, robotics, desalination, mineral mining, carbon capture, nuclear energy, and space infrastructure, among others. If something is not on this list, it's not because I lack confidence in it, but more to illustrate how broad this category is. As long as an asset falls under "abundance assets" and is not declining infrastructure, it is likely a reasonable choice.
Solar and Batteries: Solar alone represents $15-30T in capital expenditures that need financing. At this scale, solar will replace fossil fuels by 2050. This was detailed in my previous article.
Data Centers and GPUs: Cumulative capital expenditures for GPUs and data centers are between $15-35T, depending on the sensitivity of AI adoption rates. McKinsey estimates $6.7T in capital expenditures needed by 2030 alone. My consistent logic is: if you give computers more computing power, they will compute more and take on more complex tasks. Moore's Law has its limits, but we are entering an era of atomic-level engineering and vertical layering of GPUs, and even these advances will not stop us from building more computing power. This does not yet factor in quantum computing, which could drive another wave of distributed expansion in computing power.
Robotics: The automation of human tasks will be a defining feature of the world we are transitioning into. Robots, whether specialized warehouse systems or humanoid robots for daily physical tasks, will replace human labor, giving us more freedom. Robotics alone could require $8-35T in capital expenditures by 2050.
EV Infrastructure: The electrification of transportation (EVs, railways, aircraft, drones, charging networks, ships, ports) is on the verge of a massive shift from a fossil-based to an electric-based system. Estimated capital expenditures are around $10-25T by 2050. Autonomous driving itself will ensure no car sits idle; they will serve society 24/7.
Nuclear Energy: I have a love-hate relationship with nuclear energy as an abundance asset. It is a solid choice for generating large amounts of energy. However, nuclear energy is deeply tied to policy, making it difficult to innovate and even harder to finance. Projects tend to be more expensive and take longer than expected. Small modular reactors and better policy frameworks could change this. My capital expenditure estimate for 2050 is conservative, at $3-8T, constrained by policy.
Solar-Powered Desalination: Desalination is not new. It has existed for decades, and Middle Eastern countries already rely heavily on it. It is still relatively expensive, but with scale benefits and solar energy development, we will be able to obtain nearly free water anywhere in the world. Required capital expenditure: $6-12T by 2050.
CO2 Capture: Growth will be driven by government incentives. Estimated capital expenditure: $3-8T by 2050.
Critical Minerals: Copper, lithium, nickel, and rare earths that drive electrification, robotics, and more. Estimated capital expenditure: $5-15T by 2050.
Digital Networks: Fiber optics, communication towers, and satellite ground stations. Estimated capital expenditure: $6-15T by 2050.
Space Infrastructure: Space as a scaling factor will grow significantly with the scale effects of transportation and launches. Space will become an infrastructure investment opportunity over the coming decades. A conservative capital expenditure estimate for 2050 is $2-6T, but this number could have a higher multiplier. If launch costs decrease by 10-50 times along the historical cost curve, the opportunity could expand to $10-30T, and up to $50T in extreme cases. This includes: satellite constellations $3-8T, launch infrastructure $1-3T, orbital infrastructure (fuel tugs, service stations, essentially orbital logistics hubs) $2-7T, space-based solar power $2-10T, space manufacturing $1-5T, and lunar infrastructure $1-5T.
I skipped hydrogen production because I am unsure how it will evolve within the broader electrification transition.
In total, financing infrastructure could present an opportunity of about $100-200T for DeFi. For reference, the world's top ten banks collectively manage about $13T in assets under management. Successfully financing a large part of this transition would make Aave the largest financial network to date.
Choosing the Right Form for Aave
Infrastructure financing in DeFi can take two main forms.
Path One: Yield-Bearing Stablecoins (YBS)
YBS is becoming a powerful example of off-chain income distribution to on-chain users. Ethena primarily achieves this through basis trading; USD.ai does so through GPU financing. Staking sUSDai yields an APY of 10-15%.
From Aave's perspective, the growth of YBS directly translates into protocol growth. Aave is a recycling machine: if the yield from YBS infrastructure products is higher than Aave's cost of capital (around 4-5%), there is a recycling opportunity: borrow liquidity from Aave using YBS as collateral and redeploy it. I see YBS as on-chain yield distribution wrappers, with characteristics similar to traditional off-chain funds.
Path Two: Direct Collateralization
Using tokenized infrastructure directly as collateral means the yield or economic returns remain off-chain or with the borrower, but flow into Aave through collateral and borrowing demand, generating a supply yield in stablecoins for depositors. This path also does not aim for a stable net asset value, making it well-suited for assets whose net asset value fluctuates and cannot pass the stablecoin test.
Which path will win? Hard to say. Both have advantages, and Aave supports both models well. Examples of YBS include Ethena's sUSDe and Maple's SyrupUSDT. Examples of direct collateralization include Tether's gold (xAUT), Bitcoin and Ethereum collateralized loans, and the JAAA RWA fund—where the underlying economic returns belong to the asset owner, in exchange for indirectly paying interest to on-chain depositors via Aave. It is worth noting that Aave's own aTokens (e.g., aUSDC) are, in a sense, the earliest form of on-chain YBS in such use cases.
The two paths depend on the user type. The user profile might be an on-chain allocator maximizing YBS yield; the borrower in the latter case might be an operator or fund looking to scale liquidity allocation and build more without directly requiring on-chain yield distribution.
Is the Yield Sufficient?
While DeFi currently does have excess capital in the current interest rate environment, infrastructure financing should provide enough upside to shift this capital. Average equity IRR by sector: solar 10%, batteries 12%, data centers 13%, EV charging infrastructure 13%, water infrastructure 9%, space infrastructure around 18%. The higher the technology risk and the earlier on the cost curve, the higher the assumed returns.
Yields can be further enhanced through strategies. Vaults on Aave V4 could allocate to solar farms yielding 8-12%, use that asset as collateral to borrow GHO (creating a high-yield profit margin for Aave), and then redeploy GHO into battery farms yielding 12-18%, or even GPU data center opportunities with annual returns of 10-20%.
DeFi users are typically sensitive to redemption risk and lock-up periods (this may change in the future as the sector matures). Infrastructure products typically generate cash flow, which helps mitigate redemption risk. Using Aave as a liquidity sleeve can make these products more accessible to users—users can supply liquidity to specialized hubs focused on these specific economic characteristics and trust assumptions, ensuring access to infrastructure opportunities while isolating and controlling risk. A key difference is that tokenizing the asset itself enables auction-based liquidations, improving the liquidity characteristics of these assets compared to slow, layered debt wrapper funds.
Aave as a Financial Infrastructure Layer
The best path for Aave to enter the RWA and infrastructure opportunities is to serve as the base layer for financing liquidity, starting from the mature end with low technical risk (solar), and then gradually moving towards riskier assets, leveraging the granular risk control provided by the Aave V4 hub-and-spoke architecture.
Today, most RWA tokenization focuses on assets with deep, liquid markets: treasury bills, money market funds, corporate credit. These assets trade smoothly, and users already have sufficient access to borrow against them. Similarly, while private credit may seem like a compelling DeFi case on the surface, it also has drawbacks. Private credit typically finances CLOs, corporations, and private equity. If the infrastructure layer is the bottom layer as I described, this is the top layer. In a world transforming faster than ever, especially at the top, assets need to tilt towards the future we are building, not the past we are leaving. A seemingly excellent asset-backed financial product might look great on paper but lose its place in tomorrow's world.
Traditional financial asset tokenization will continue to grow and will certainly be part of Aave's story, just as crypto-native assets and their growth persist. But the bigger opportunity lies in becoming the infrastructure financing layer for the future. This is what excites me about RWA and Aave.
What Does This Mean for Fintech Companies?
Large fintech companies are increasingly becoming distribution and experience layers: the interface that delivers quality financial products to end-users. I previously wrote that leveraging DeFi can enable fintech companies to unlock a leaner cost structure for new financial products. DeFi runs almost autonomously, is more transparent, and ensures performance through smart contracts. It requires less operational expenditure, enables tighter profit margins, and opens up new financial opportunities.
In a world where financial access is commoditized and no longer provides a differentiated value proposition, the ability to access unique yield opportunities brings new value to fintech companies (and even banks) and their users. Fintech companies actively participating in the stablecoin issuance space also means potential new use case opportunities, as well as genuine borrowing demand for stablecoins collateralized by infrastructure assets.
Through Aave Kit and the Aave App, fintech companies and banks can be the perfect distribution channel for yields generated from infrastructure collateral on Aave V4, collateral that is relevant to the future we are building. Connecting Aave to fintech companies and banks to inject capital could accelerate the transition to a world of abundance by 10-15 years. This is a unique opportunity for Aave and its various partners to capture and share the market value of $200T.
