The World Economic Forum’s prediction of a US$3.5 trillion decentralised physical infrastructure network, or DePIN, by 2028 is almost certainly giving investors in each and every DePIN project a warm, fuzzy feeling of self-validation. I have a hard time arguing with a trillion-dollar market cap…but most of these investors are focused on the trees and not the forest, marvelling at individual projects like Helium’s wireless network or Render’s GPU marketplace without addressing the underlying bottleneck: an entire multi-trillion-dollar physical infrastructure sector trying to bootstrap itself onto decentralised networks that are fragmented islands unto themselves.
DePIN’s existing US$27 billion market cap is less than one per cent of the expected US$3.5 trillion opportunity by 2028. And the US$11 billion total value locked across cross-chain bridges today is being exploited every few months with quarterly major hacks, over US$2.5 billion stolen since 2021. We are collectively trying to build the next interstate highway system using nothing more than rope bridges.
The fact is that DePIN, as a sector, is held back by the lack of fundamental infrastructure needed to function at scale. Right now, each individual project is like a country, building its own border controls to admit people from other networks. Consider how these projects actually work: A single transaction might involve sensor data from IoT devices on one blockchain, compute resources on another, data storage on a third, and then finally a payment settlement layer on a fourth chain. At the moment, every bridge is a choke point that requires expensive, centralised relayers, repeated O(N2) security checks, and adds latency and fees that make large-scale use cases economically infeasible.
Core Scientific pivoting from Bitcoin mining to AI infrastructure is an excellent example. A subsidiary, Core Scientific Cloud, is already generating 80 per cent gross margins by repurposing their miners for AI compute! But only because it’s a fully integrated system, 100 per cent centralised with no real dependencies on other chains. If they had to bridge that compute power with storage networks or IoT sensor data streams on separate chains, those margins evaporate.

Recent legislation such as the GENIUS Act aims to provide clearer regulatory frameworks for stablecoins and digital commodities. Jurisdictions that establish regulatory clarity may gain an advantage over regions still working through fragmented approaches. But before we can build that cross-chain DePIN infrastructure, three things need to happen:
First, we need to build cross-chain communication natively, not through wrapped assets or centralised relayers. The Inter-Blockchain Communication (IBC) protocol has seen over US$30 billion in volume across over 12 chains per year with zero exploits as of today’s date. Interoperability is possible on a massive scale if we build it correctly from the ground up.
Second, we need liquidity layers that unify value transfer instead of fragmenting capital across chains. The user capital efficiency of current DePIN networks is orders of magnitude worse than the traditional web because every project forces you to hold a separate wallet with its own native token just to participate. A farmer using DePIN-powered blockchain coordinated irrigation should not need to hold five different wallets and five different tokens to receive payment.
Third, standardised physical-world attestation data. Every DePIN network will have validators attesting to some piece of physical world truthiness, whether it’s Helium validators attesting to wireless coverage, or Filecoin nodes validating data storage proofs. All of that data must be readable and interoperable cross-chain, or we risk building an entire digital infrastructure industry version of the Tower of Babel.
The use cases for DePIN go far beyond speculative opportunity. McKinsey estimates that value unlock through tokenisation of real world assets could reach US$2 trillion by 2030. But DePIN is the last missing puzzle piece to actually bridging the gap between digital tokens and real world utility, but only if we build the infrastructure to support it.
Projects based in jurisdictions with clearer regulatory frameworks are better positioned to capture this value, and recent market performance reflects investor appetite for certainty. Global capital is already flowing into DePIN initiatives in regions such as the United States, where legal clarity and technical capacity offer stronger foundations for scaling.
The counterintuitive part is that DePIN doesn’t need to anoint one or two big winners. Helium doesn’t have to completely beat traditional telecom. Render doesn’t have to bankrupt AWS. Each DePIN network is competing against centralised infrastructure, not other DePIN networks. The real revolution will happen when those networks all interconnect and coordinate in a completely new way to provide emergent value that the legacy systems can never replicate.

Think of a supply chain where IoT sensors track physical shipments, decentralised compute optimises the route, distributed storage acts as the immutable ledger, and smart contracts auto-execute payments — all coordinated across different blockchains, with no centralised choke points or single points of failure. It’s all technologically possible right now. The missing part is the infrastructure that connects it all.
This is an infrastructure moment. Just as the interstate highway system transformed commerce in the 20th century, a new generation of cross-chain physical-digital infrastructure is now emerging to define the next era of convergence. Recent legislative efforts, such as the CLARITY and GENIUS Acts, illustrate how regulatory frameworks can lay the foundation for growth. What is needed next is the vision to move beyond siloed DePIN projects and begin constructing the connective tissue that can bind them into a unified network.
The reason DePIN is a US$3.5 trillion opportunity isn’t because someone is going to pick three or four winner projects. It’s because each of those thousands of projects will win when we build the infrastructure to connect them all. Every nation and company that understands that is going to own a piece of the future of physical infrastructure. The future will be shaped by the regions that build scalable, interoperable infrastructure first.
The trillion-dollar question is not if DePIN will revolutionise physical infrastructure. The question is which regions will succeed in building the cross-chain highways to capture that value. With regulatory clarity beginning to emerge in multiple markets, the race has officially begun.
