Insights
Large institutional holder reports shared voting and dispositive power just under 6%.
Citadel-related entities disclose shared voting and dispositive power over between 8.79M and 10.1M shares, representing roughly 5.1–5.9% of the class based on the filing's stated outstanding share count of 172,595,406 as of May 18, 2026.
The statement is filed as a joint passive Schedule 13G; the filing emphasizes shared power and includes corporate relationships among reporting entities and Mr. Griffin. Subsequent disclosures would show if positions change or voting arrangements differ.
Position sizes create modest concentration but remain below 10% reporting thresholds.
The reported holdings (examples: 10,085,671 and 8,792,484 shares) are quantified and tied to an explicit outstanding share figure. Percentages are computed in the filing, not derived here.
Cash‑flow treatment and trading intent are not stated; the filing describes voting/dispositive powers only. Future Form 13D/13G amendments or Form 4s would provide transactional detail if activity occurs.

"The joint <i>Schedule 13G</i> lists shared dispositive and voting power"
A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.
shared dispositive powermarket
"Shared dispositive power of 10,085,671.00 is reported"
beneficially ownregulatory
"Citadel Securities LLC may be deemed to beneficially own 8,792,484 Shares"
Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.
joint filingregulatory
"This is being jointly filed by Citadel Securities GP LLC and others"
Citadel-related entities report shared power over up to 10,085,671 shares (5.8%). The filing lists Citadel Securities LLC with 8,792,484 shares (5.1%), using 172,595,406 shares outstanding as of May 18, 2026 to compute percentages.
How much does Kenneth Griffin control in POET (POET)?
Kenneth Griffin is reported with shared voting and dispositive power over 10,110,970 shares (5.9%). The filing attributes those shares to the reporting persons and ties percentages to the May 18, 2026 outstanding share count of 172,595,406.
Are these holdings active trading positions or passive investments?
The joint filing is submitted on Schedule 13G, which indicates a passive reporting status. The statement lists voting and dispositive powers but does not disclose trading intent, transactions, or plans to buy or sell in this excerpt.
What dates anchor the ownership percentages in the filing?
Percentages are based on 172,595,406 Shares outstanding as of May 18, 2026, per the filing. Holdings are reported "as of the opening of the market on July 8, 2026" except where the outstanding figure is cited from May 18, 2026.
