Fact Check
The statement is confirmed by the official Polkadot X (Twitter) account, a primary source, which announced that Referendum 1710 was passed to cap the DOT supply at 2.1 billion. This is corroborated by multiple reputable crypto news outlets. A single source citing a 21 billion cap appears to be a typographical error, as it contradicts the primary source and the consensus of other evidence.

Summary

Polkadot’s decentralized autonomous organization passed Referendum 1710 with 81% approval, capping DOT supply at 2.1 billion tokens. Currently at 1.6 billion DOT in circulation, Polkadot previously minted 120 million new tokens annually with no cap. The new framework introduces issuance cuts every two years starting March 14, reducing annual issuance from 120 million in 2025 to under 20 million in the early 2030s, stabilizing supply near 1.91 billion by 2040. The model emphasizes scarcity and long-term alignment, similar to Bitcoin’s halving approach. The change follows Polkadot’s launch of Polkadot Capital Group to attract institutional investors. DOT traded at $4.18, down 4.6% on the day of the announcement.
