The Ethereum validator entry queue has swelled to roughly 2.5 million ETH, with new stakers waiting approximately 43 days to activate while the exit queue remained largely empty, according to data from Beaconcha.in.

Thomas Brunner, Head of Custody and Staking at Sygnum Bank, said the backlog is not the clean bullish signal it appears to be on the surface.

"The queue is genuinely long, and part of that is real demand we've observed with spot ETF and at our own level," Brunner said in a written interview with The Block. "But a meaningful share of this staking backlog is mechanical, not directional and it stems from last year's Pectra upgrade."

The Dencun upgrade lowered the daily validator entry rate to roughly 57,600 ETH, Brunner said, and Pectra did not raise it. Pectra also allows validators to hold up to 2,048 ETH each and compound automatically, so large operators are now topping up existing validators. Every top-up, some as small as 1 ETH, waits in the same queue as fresh stakers.

"This backlog reflects operators rearranging and compounding stake they already hold, not just new appetite for ETH," Brunner said.
