Ethereum and Solana Are Capping New Supply-And That Could Reweight Crypto Money Flows

High staking ratios are tightening liquid supply on both chains

The shared setup is straightforward: both networks are locking up a large share of tokens in validation. In Ethereum, staking surpassed one-third of supply earlier this year. In Solana, 62.2% of total supply is staked. That matters because coins committed to network security are generally less available for trading.

Why Ethereum has the cleaner tightening setup

Ethereum's setup looks tighter because the lock-up is still deepening. The validator entry queue is adding about 1.75 million ETH per month, which means the market is watching a larger share of ETH move into staking rather than staying in liquid hands. That gives Ethereum a clearer shrinking-float narrative than most other major chains.

The key split: ETH leans toward scarcity, SOL still leans toward yield

Bulls on Ethereum see high staking as a rerating driver if supply growth keeps getting constrained. Bears counter that this is still a debate around a proposal, not a completed shift. Solana, by contrast, already has the larger immediate staking figure, but its model is different. SOL still carries 4.60% current annual inflation, paid largely through protocol inflation and staking rewards. That makes Solana's case less about pure scarcity and more about whether yield and network behavior can outpace dilution.

Ethereum is trying to manage dilution before staking gets too large

Ethereum's scarcity setup now raises a different question: what happens if staking becomes too successful?

ETH supply still comes down to issuance versus burns

Ethereum has no hard cap, but it also no longer has the old issuance burden. Roughly 120.7 million ETH are in circulation, and the net supply path depends on the tug-of-war between issuance and burn. EIP-8361 matters because it tries to address dilution as staking grows. The proposal targets 0.5% annual inflation at 20% staking and zero inflation at 50% staking. In other words, it is an attempt to soften future dilution rather than leave issuance on autopilot.

Why this is still a forward-looking debate

The timing is the main point of disagreement. The staking ratio is already above one-third, and the queue is still adding about 1.75 million ETH per month. The proposal argues that, if nothing changes, more than 70 million ETH could be staked by early 2028. That makes the case for a pre-emptive supply brake. But it also remains a proposal, not an active protocol rule, so investors still have to weigh policy risk against the scarcity narrative.

What would make the ETH case stronger

If EIP-8361 stays on the policy roadmap, Ethereum's supply curve looks increasingly biased toward softer dilution as more capital moves into validators. If the discussion stalls or the final design is weakened, that narrative gets less compelling. For now, the live variable is whether this remains a credible policy track rather than a theoretical exercise.

Solana's model still pairs low float with meaningful inflation

Solana's approach is different. It keeps inflation running and keeps staking yields relevant, asking the market to prove that behavior can absorb new supply. On paper, the setup is still impressive: 62.2% of total supply is staked out of 598.58 million SOL, leaving a smaller free-floating pool than most chains. But SOL still has 4.60% current annual inflation, even though the design aims for 1.5% long-term inflation.

The staked share is not the same as locked supply

That high staking ratio does not fully determine how tight liquidity feels. Seven-figure amounts of SOL are staked and unstaked in most epochs, which means part of the sidelined supply is more elastic than the headline rate suggests. Fee burns also help, but only modestly: they have averaged 3.2% of total staking rewards over the recent 100 epochs, with a prior peak of 7.8%. That provides some offset, but not enough to fully counter current issuance on its own.

Usage still has to become holder value

Solana already has the advantage of visible activity. It enters the year as a high-usage chain with rapidly growing US dollar payments. The harder question is whether that activity translates into durable value capture for SOL holders. For investors comparing the two assets, that is the main split: Ethereum is being discussed as a tightening-supply story, while Solana still has to show that network use and reward recycling can justify a more emissive token model.
