Lightning’s Capacity Hit a Record. Its Node Count Keeps Falling.

Bitcoin’s Lightning Network is holding more money than ever and running on fewer machines than it did four years ago. Both things are true at once, and together they describe how the payment layer is actually maturing: capacity is climbing while the number of independent nodes drifts down. The growth is real. So is the concentration underneath it.

The capacity figure is the headline. Public Lightning channels hold roughly 5,000 BTC — about $313 million at late-June prices — and researchers estimate that counting private channels pushes the total well above 12,000 BTC. Public capacity touched fresh all-time highs earlier in 2026. On the usage side, River measured Lightning volume topping $1.17 billion in a single recent month across 5.22 million transactions, with the average payment climbing to $223, up from $118 a year earlier.

Fewer nodes, bigger channels

The node count runs the other way. Bitcoin Visuals data put Lightning at roughly 14,940 nodes late in 2025, down from a peak near 20,700 in early 2022. Capacity is rising not because more people are spinning up nodes but because more bitcoin is flowing into the channels that already exist — and the entities doing the filling are large exchanges and institutional players routing a growing share of withdrawals over Lightning, not a wave of new hobbyist operators.

Capacity and node count measure different things. Capacity is how much value the network can move; node count is how many independent hands route it. A network can get better at payments and more concentrated in its plumbing simultaneously — which is precisely what the numbers show.

No longer bitcoin-only

Lightning also stopped being a bitcoin-only system this year. After a long integration, Tether confirmed in March 2026 that its dollar stablecoin runs on Bitcoin and Lightning via Lightning Labs’ Taproot Assets protocol. That widens what the rails can carry — dollars moving at bitcoin speed — and further tilts activity toward the well-capitalized operators equipped to handle it. The layer built to let anyone route a payment is increasingly routed by the few with the balance sheets to do it at scale.

The optimistic read is that this is what a payment network looks like when it grows up: fewer but sturdier, better-capitalized nodes that route reliably, and capacity deep enough for merchants to feel. Users care whether a payment settles, not how many nodes exist. The worry is the mirror image — that routing concentrates among a handful of hubs, reintroducing the choke points bitcoin was meant to design out. The honest verdict today is that Lightning is getting stronger as a payments system and thinner as a decentralized one, and it is worth watching which trend compounds.

Why it matters: a record capacity number can hide a centralizing network — on Lightning, the money is pooling into fewer, larger channels even as the map of who runs them shrinks.

Capacity (~5,000 BTC public, >12,000 BTC incl. private), node counts (~14,940 late-2025 vs ~20,700 early-2022, Bitcoin Visuals), and volume/average-payment figures (River) are as reported across 2026; the ATH refers to public channel capacity earlier in 2026.
