Who owns Blockratize, Inc. (Polymarket), Common Stock

Blockratize, Inc. (Polymarket), Common Stock - Profile

Blockratize, Inc. is the Delaware company that trades as Polymarket, a prediction market where users buy and sell shares in the outcomes of future events across politics, sport, economics and culture, with orders matched peer to peer through smart contracts and shares settling at one dollar or zero once the event resolves. Shayne Coplan founded the business in 2020 and it is run from New York. A January 2022 order from the Commodity Futures Trading Commission fined the company 1.4 million dollars for offering off exchange event based binary options without registering as a designated contract market or swap execution facility and required it to wind down non compliant markets, which pushed United States users off the main platform. In July 2025 Polymarket bought QCEX, a CFTC licensed derivatives exchange and clearing house, for 112 million dollars, and now operates a regulated domestic venue trading as Polymarket US alongside its global platform.

The disclosed stakes

One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.

Where each figure comes from

A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

• Intercontinental Exchange, Inc., as of 30 Apr 2026. In April 2026 ICE completed a tender offer to acquire 'approximately 0.4 million shares of common stock of Blockratize, Inc., doing business as Polymarket, for an aggregate purchase price of $40 million.' The filing gives only an approximate share count ('approximately 0.4 million'), so the 400,000 recorded here is that approximation, not a precise filed count; value_as_of is the April 2026 transaction date, not a subsequent fair-value remeasurement date. Combined with the existing Series D/E preferred stakes, ICE concluded it has significant influence over Polymarket and accounts for this common stock tranche under the equity method (folded into the same combined 'equity method investments' balance as OCC, see that holding's method_note). The 10-Q states only that 'our common stock investment represented less than 1% ownership of Polymarket shares on both an outstanding and fully diluted basis' with no precise percentage given, so pct_of_target is left null rather than guessing a number for a qualitative 'less than 1%' disclosure. source
