Riot Platforms is a registered legal entity registered in United States under 20001144259, and its current status with Colorado Secretary of State is active. The company was incorporated on 24 July 2000 and lists its registered address as Castle Rock, United States. 5 shareholders are on record for Riot Platforms, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Colorado Secretary of State and was last updated on 4 October 2026.

Shareholders

5

Five shareholders are currently on record for Riot Platforms, reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.

The largest of these is Vanguard Group Inc, holding 20% — the largest recorded stake — followed by iShares Trust-iShares Russell 2000 ETF at 4.4%; the remaining 3 shareholders shown hold smaller stakes.

The register reports 6 shareholders in total, though only the top 5 by holding are shown in this view.

Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers

5

The Ceo & Executive Director of Riot Platforms currently on record is Jason Les; five officers are currently on record for Riot Platforms, filed with Colorado Secretary of State.

The register reports 14 officers in total, including past appointments, though only the 5 most relevant records are shown here.

Management authority at Riot Platforms sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.

The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.

Group Structure

Riot Platforms has no recorded parent company — it sits at the top of its own group structure, with 6 subsidiaries recorded beneath it across 1 jurisdiction. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.

Those 6 subsidiaries span United States jurisdiction, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Three of the 6 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
