Fact-check findings
What an automated fact-checker found when it re-read Polkadot (DOT) against the sources the page cites. Only the most recent review is shown.
Read this first
These findings are produced by an automated reviewer, and its results vary between runs: the same page, checked three times on the same day, came back with 15%, 20% and 34% of its claims disputed, mostly because each run extracted a different number of claims. Treat what follows as leads, not rulings.
“Disputed” means the reviewer could not reconcile the claim with the evidence it cited. It does not mean the claim is false. “Unverifiable” means no reachable source settled it either way.
Nothing here changes the page on its own. A proposed correction is applied only after a human moderator approves it; until then the page reads as it did when reviewed.
disputed
5 claimsThe reviewer could not reconcile the claim with the evidence it cited. This is a lead, not a ruling that the claim is false.

“The Web3 Foundation conducted a public token sale for DOT in October 2017, raising approximately $140 million by selling 50% of an initial 10 million DOT supply.”
reviewerWeb3 Foundation ICO in October 2017 raised approximately $140 million by selling 50% of an initial 10 million DOT supplyThe page states two different ICO totals for the same October 2017 sale: $140 million here (and in the timeline) versus $145 million in the adjacent 'ICO and Parity Wallet Freeze' section. Multiple independent sources, and the page's own frozen-funds percentage math (~$98M = 60-67% of proceeds), support $145 million, making the $140 million figure the outlier.Proposed correction (not yet applied)The Web3 Foundation conducted a public token sale for DOT in October 2017, raising approximately $145 million by selling 50% of an initial 10 million DOT supply. - #4[disputed][awaiting moderator]in the timeline
“Polkadot ICO opens; Web3 Foundation raises approximately $140 million by selling 50% of the initial 10 million DOT token supply.”

“In Q4 2025, the treasury recorded a quarterly report flagging negative net flows of nearly 101,000 DOT in a single month.”
reviewerIn Q4 2025, the treasury recorded a quarterly report flagging negative net flows of nearly 101,000 DOT in a single monthThe page's own cited source (the 2025-Q4 Polkadot Treasury Report) reports the opposite of what is claimed: a first-ever net profit, not negative flows. The ~101,000 DOT deficit event actually occurred in April 2025 and appears to have been conflated with the Q4 2025 report in the page's drafting.Proposed correction (not yet applied)In April 2025, the treasury recorded negative net flows of nearly 101,000 DOT in a single month; the subsequent 2025-Q4 treasury report instead showed the treasury's first net profit (1.6 million DOT) under the current OpenGov system. - #24[disputed][awaiting moderator]in section: Ecosystem Exodus: Moonbeam Migration
“The exit contributed to bearish market sentiment around DOT, with the token dropping approximately 3.6% in the days surrounding the announcement.”
reviewerThe Moonbeam exit contributed to bearish DOT sentiment, with the token dropping approximately 3.6% in the days surrounding the announcementThe cited source (titled 'Polkadot's 3.02% Drop: Moonbeam Migration to Base' in the page's own source list) reports a 3.02% move over about 8 hours, not the 3.6% figure stated in the body text, and frames it as an hours-long move rather than a multi-day one.Proposed correction (not yet applied)The exit contributed to bearish market sentiment around DOT, with the token dropping approximately 3.02% in the hours surrounding the announcement. - #25[disputed][awaiting moderator]in section: Tokenomics: Hard Supply Cap and Issuance Reform
“On September 14, 2025, the Polkadot community passed a 'Wish for Change' governance proposal instituting a hard supply cap of 2.1 billion DOT. This was enacted on-chain in March 2026 alongside a 53.6% reduction in annual token issuance, from approximately 120 million to approximately 56.88 million DOT per year.”
reviewerOn September 14, 2025, the community passed 'Wish for Change,' instituting a 2.1 billion DOT hard cap, enacted on-chain in March 2026 with a 53.6% reduction in annual issuance from ~120 million to ~56.88 million DOT/yearThe percentage reduction is off: 120 million reduced by 53.6% would be approximately 55.68 million, not 56.88 million. Multiple independent sources report a 52.6% cut yielding 56.88 million, which is arithmetically consistent (120M x 0.474 = 56.88M) and matches the ending figure the page itself cites. The 53.6% figure in the page appears to be a transposition error.Proposed correction (not yet applied)On September 14, 2025, the Polkadot community passed a 'Wish for Change' governance proposal instituting a hard supply cap of 2.1 billion DOT.

“A governance proposal to reduce inflation was rejected by 57% of participating voters, further complicating sustainability efforts.”
reviewerA governance proposal to reduce inflation was rejected by 57% of participating votersThe 57% rejection figure itself is accurate, but the claim is presented with no date and is sandwiched between a Q4 2025 reference and a May 2026 reference, which invites readers to assume it is roughly contemporaneous when it in fact predates both by well over a year. No cited source is given for this specific sentence.
