The number of Solana validators has sharply decreased to 795 by the end of 2025, a significant drop from 2,500 in March 2023. This decline is attributed to rising operational costs that have outpaced returns, leading to financial losses for operators. Despite the network's robust activity, generating $1.4 billion in annual revenue, the profitability for validators has diminished, forcing smaller operators to exit the market. In December 2025, two validators ceased operations due to financial pressures, highlighting the growing concerns over the network's decentralization and security. The staking requirements have surged, now exceeding $17 million for a 0% commission, further straining smaller validators. This situation has prompted interest in altcoins with more favorable validator economics.
