Ethereum leads 2025 crypto inflows with $4.21 billion, Arbitrum sees $5.13 billion outflow

Capital movements reshape crypto landscape in 2025

New on-chain data reveals some pretty striking patterns in how money moved between cryptocurrency networks this year. I think what’s interesting is that we’re seeing clear winners and losers when it comes to investor capital allocation. The numbers tell a story that’s perhaps more dramatic than many expected.

Ethereum appears to have been the main beneficiary of this capital rotation. The network recorded a net inflow of $4.21 billion throughout 2025. That’s a substantial amount, and it suggests that despite all the competition from newer layer-1 and layer-2 solutions, Ethereum still commands significant investor confidence.

Surprising performers and notable outflows

What caught my attention was Hyperliquid’s performance. The network, known for its derivatives trading and high-volume transactions, pulled in $2.88 billion in net inflows. That’s a pretty strong showing for a platform that doesn’t get as much mainstream attention as some of the bigger names.

Other networks with positive inflows included Sonic at $1.25 billion, WorldChain with $671 million, and Solana at $625 million. Starknet, edgeX, Ink, Injective, and even Bitcoin all showed positive numbers, though Bitcoin’s $155 million inflow seems modest compared to some of the altcoins.

But here’s where things get really interesting. Arbitrum, one of the largest Ethereum layer-2 scaling solutions, experienced a net outflow of $5.13 billion. That’s a massive movement of capital away from the network. I’m not entirely sure what drove this exodus, but it’s certainly worth noting.

What the data might mean

These capital flows could indicate several things. Maybe investors are rotating from layer-2 solutions back to Ethereum mainnet as gas fees become more manageable. Or perhaps there’s a broader shift happening in how people allocate their crypto investments.

The data shows that while some ecosystems are attracting fresh capital, others are seeing significant departures. This kind of rotation isn’t unusual in crypto markets, but the scale of some of these movements is noteworthy.

It’s worth remembering that these are just numbers from one year. Crypto markets can be volatile, and what looks like a trend today might reverse tomorrow. Still, the $4.21 billion flowing into Ethereum versus the $5.13 billion leaving Arbitrum creates a pretty clear picture of where investor sentiment was concentrated in 2025.

These capital movements might influence development priorities, network security, and overall ecosystem health. Networks with strong inflows typically have more resources for development and growth, while those experiencing outflows might need to reassess their strategies.

I think the takeaway here is that the crypto landscape continues to evolve in unexpected ways. The competition for capital remains fierce, and networks need to demonstrate real value to attract and retain investment.
