Sphere Entertainment Co.
A company behind the Sphere, the giant glowing ball-shaped Las Vegas arena wrapped in a huge LED screen that hosts concerts, original shows like The Wizard of Oz at Sphere, and brand events. Born from the Madison Square Garden family, it spun off in 2020 and again in 2023 to become its own business, alongside MSG Networks, which broadcasts New York Knicks and Rangers games. Its name is simply its shape—the building is literally a sphere.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: +161.0K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
