Lightning Network Capacity Map: Liquidity Distribution

Where Is Lightning Network Liquidity Concentrated?

The Lightning Network's public capacity surpassed 5,600 BTC in December 2025, setting a new all-time high worth roughly $490 million at the time. But that liquidity is not evenly distributed. A small number of institutional nodes control the majority of capacity, geographic concentration skews heavily toward North America and Europe, and the gap between the largest and smallest participants continues to widen.

Understanding where liquidity sits on the network matters for anyone building on Lightning: routing reliability, fee economics, and censorship resistance all depend on the topology of the channel graph. This page breaks down the current distribution of Lightning Network capacity across nodes, geographies, and channel sizes.

Top Nodes by Capacity

The top 10 nodes by channel capacity control approximately 62% of all public liquidity on the network. This concentration has increased over time as exchanges and professional liquidity service providers have replaced hobbyist node operators.

ACINQ stands out as the largest single node, operating the backend infrastructure for Phoenix Wallet. Its ~2,245 channels make it one of the most connected routing hubs on the network. Bitfinex runs two major nodes (bfx-lnd0 and bfx-lnd1) with a combined capacity exceeding 510 BTC, making it the largest exchange presence by total liquidity.

Binance's node is notable for a different reason: ~306 BTC concentrated in only ~136 channels, meaning an average channel size of over 2 BTC. This reflects an exchange-optimized topology designed for large withdrawals rather than broad routing connectivity. For more on how routing fees work across these nodes, see our Lightning routing fee comparison.

Geographic Distribution

Lightning Network nodes are heavily concentrated in a handful of countries. North America and Europe together account for approximately 88% of all reachable nodes.

Germany's strong showing (13.4%) reflects its large data center industry and established Bitcoin community. The relative absence of nodes in regions with high Lightning usage (such as El Salvador, where Bitcoin is legal tender) suggests that many end users connect through custodial wallets and LSPs rather than running their own nodes.

This geographic concentration creates potential risks: regulatory action in a single jurisdiction could impact a significant share of network infrastructure. Wallet of Satoshi's exit from EU markets in January 2026, driven by MiCA and DAC8 regulations, demonstrated how quickly the routing topology can shift when regulations change.

Capacity Growth Over Time

Lightning Network capacity has grown from roughly 1,100 BTC at the end of 2020 to over 5,600 BTC by late 2025. But the growth was not linear: a significant mid-2025 dip saw capacity drop to approximately 3,850 BTC before recovering sharply as exchanges added large channels.

The divergence between capacity and node count is the defining trend. Node count peaked around 20,700 in mid-2022 and has declined to roughly 15,000, while capacity has grown. Fewer operators hold more bitcoin: the network is becoming more efficient but more concentrated.

Channel Size Distribution

The distribution of payment channel sizes reveals extreme inequality. At roughly 5,600 BTC spread across ~48,000 channels, the average channel size is approximately 0.117 BTC (~$10,000 at current prices). But the median node capacity is only 0.002 BTC (~$170), indicating that most participants hold very small positions while a few large nodes dominate.

The network's Gini coefficient for capacity distribution reached approximately 0.97 in 2025, up from 0.87 in 2018. A Gini coefficient of 1.0 represents perfect inequality (one entity holds everything), so the Lightning Network's current distribution approaches extreme concentration. The top 10% of nodes hold approximately 80% of all staked BTC.

This concentration is partly structural: Lightning's routing model benefits from hub nodes with large, well-connected channels. Payments find paths more reliably when liquidity pools at a few central points. But it also means that the failure or exit of a single major node (such as ACINQ or a Bitfinex node) could temporarily disrupt routing for large portions of the network.

Network Volume and Transaction Activity

In November 2025, the Lightning Network processed approximately $1.17 billion across 5.22 million transactions, according to River Financial data. This represents substantial growth from early years, though still a fraction of on-chain Bitcoin volume.

Coinbase reported that roughly 15% of Bitcoin withdrawals on its platform are now routed via Lightning, driven by its integration with Lightspark. In February 2026, Secure Digital Markets executed a pilot transfer of approximately $1 million to Kraken using Lightning, demonstrating enterprise-scale transfer capability.

Recent Developments Affecting Topology

Several protocol-level and market changes are reshaping Lightning Network liquidity distribution:

• Taproot Assets reached v0.7 in December 2025, and Tether confirmed USDT live on Lightning via this protocol in March 2026, enabling stablecoins to move across Lightning channels
• Channel splicing allows nodes to resize channels without closing and reopening them, reducing on-chain fee overhead for liquidity rebalancing
• Channel factories aim to batch multiple channel opens into single on-chain transactions, potentially lowering the barrier for new node operators
• Exchange adoption (Binance, OKX, Kraken) drove the late-2025 capacity surge, but their large, concentrated channels create potential single points of failure
• Wallet of Satoshi exited EU markets in January 2026 due to MiCA/DAC8 regulations, demonstrating how regulatory changes can alter network topology quickly

Layer 2 solutions beyond Lightning are also emerging. Spark provides a Bitcoin-native layer for instant transfers and stablecoin payments (including USDB) without requiring users to manage channel liquidity directly. For a comparison of different Bitcoin scaling approaches, see our Bitcoin Layer 2 comparison.

Implications for Routing and Payments

The current liquidity distribution has direct consequences for payment routing on Lightning:

• Payments between well-connected nodes (exchanges, LSPs) succeed at high rates with low fees
• Payments involving small, peripheral nodes often require multiple routing attempts and may fail for amounts above a few hundred thousand satoshis
• Inbound liquidity remains the primary constraint for merchants and new node operators: receiving payments requires someone else to open a channel toward you
• Multipath payments help split large payments across multiple routes, partially mitigating liquidity bottlenecks
• Professional Lightning Service Providers increasingly abstract away channel management for end users, trading decentralization for usability

Frequently Asked Questions

What is the total capacity of the Lightning Network?

As of late 2025, the Lightning Network's public capacity reached approximately 5,637 BTC, worth roughly $490 million at the time. This represents only publicly visible channels: total capacity including private channels is estimated to exceed 12,000 BTC. Capacity fluctuates as nodes open and close channels.

Who are the biggest Lightning Network nodes?

ACINQ is the largest single node with approximately 446 BTC across ~2,245 channels. Bitfinex operates two large nodes with a combined ~510 BTC. Binance (~306 BTC), Kraken (~263 BTC), and Block (~210 BTC) round out the top five. Exchanges and professional LSPs dominate the top of the capacity rankings.

Is the Lightning Network becoming more centralized?

By most metrics, yes. The Gini coefficient for capacity distribution reached ~0.97 in 2025 (up from ~0.87 in 2018), and node counts have declined from a peak of ~20,700 in mid-2022 to roughly 15,000. The top 10 nodes control approximately 62% of all public capacity. This hub-and-spoke pattern improves routing efficiency but introduces concentration risk.

How many nodes does the Lightning Network have?

The number of public Lightning nodes peaked at approximately 20,700 in mid-2022 and has since declined to roughly 14,000 to 17,000 depending on the measurement source and whether inactive or Tor-only nodes are included. Public channel count sits at approximately 40,000 to 50,000. Both figures fluctuate as operators come and go.

What is the average Lightning Network channel size?

The average channel size is approximately 0.117 BTC (~$10,000), calculated from ~5,600 BTC across ~48,000 channels. However, the median is much lower: the median node capacity is only ~0.002 BTC (~$170). This gap reflects extreme concentration where a few hundred large nodes hold the vast majority of liquidity.

Which countries have the most Lightning nodes?

The United States leads with approximately 30.6% of all reachable Lightning nodes, followed by Germany at 13.4%, France at 4.7%, and Canada at 4.3%. North America and Europe together account for roughly 88% of all nodes. Regions with high user adoption (like Central America) are underrepresented because users typically connect through custodial wallets rather than running their own infrastructure.

Can you run USDT on the Lightning Network?

Yes. In March 2026, Tether confirmed that USDT is live on Lightning via Lightning Labs' Taproot Assets protocol (v0.7, released December 2025). This enables stablecoin transfers over Lightning channels, though adoption is still in early stages and liquidity for Taproot Asset channels is limited compared to native BTC channels.
