Polkadot 今日价格。

Polkadot reached an all-time high of $54.98 on November 4, 2021, during the peak of the 2021 crypto bull cycle. DOT has not retested that level in subsequent cycles, trading significantly below the ATH through 2025 and 2026. Past price levels are not indicative of future performance.

Polkadot's price is shaped by network upgrades, tokenomics changes, and the competitive position of Polkadot's parachain ecosystem against rival smart contract platforms. In March 2026, Polkadot activated the most significant tokenomics reset in its history: a hard supply cap of 2.1 billion DOT and a 53.6% reduction in annual issuance, cutting token inflation from approximately 7–10% to roughly 3.1%. Institutional access expanded in March 2026 with the launch of the first US spot Polkadot ETF. Ecosystem metrics — parachain activity, Coretime demand, and developer commits — influence longer-term demand for DOT as block space is consumed.

Polkadot has a maximum supply of 2.1 billion DOT, with approximately 1.68 billion currently in circulation. The hard cap was activated on March 14, 2026 through an on-chain governance vote, replacing Polkadot's previous uncapped inflationary model that minted roughly 120 million new DOT per year. Annual issuance was reduced by 53.6% to approximately 57 million DOT per year, with issuance stepping down further over time. Because tokenomics remain governed by on-chain referenda, future parameter changes are possible via the same governance process.

Yes. The 21Shares Polkadot Trust (TDOT) launched on Nasdaq on March 6, 2026 as the first US-listed spot Polkadot exchange-traded product, holding physical DOT with Coinbase as custodian. The fund charges a 0.30% management fee, reduced to 0.09% through October 2026. TDOT followed the regulatory path established by earlier spot Bitcoin and Ethereum ETFs and provides a regulated on-ramp for institutional and brokerage investors to gain DOT exposure.

Polkadot (DOT) can be purchased on Nexo and on other major cryptocurrency exchanges.
