Resolution rules

Rules as stated by Polymarket, reproduced verbatim. Convexly has not independently reviewed them and does not endorse them; the rating's resolution-reliability pillar treats rule text as present but not independently reviewed.

This market will resolve to "Yes" if it is officially announced that eBay will be, has been, or is being acquired by or merged with GameStop, by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". Mergers or acquisitions involving eBay or its parent company, eBay Inc., and GameStop or its parent company (if applicable), will qualify. An announcement by eBay or GameStop within this market's timeframe will qualify for a "Yes" resolution, regardless of whether or when the announced acquisition/merger actually occurs. Announcements of partial sales may count, as long as GameStop acquires a controlling interest in eBay. A “controlling interest” refers to a change in ownership sufficient to control the company’s strategic decisions (typically more than 50% of equity, or equivalent control via voting and governance rights). Transactions or investments that do not result in a transfer of controlling interest will not count. The primary resolution source for this market will be official information from eBay and GameStop; however, a consensus of credible reporting may also be used.Show the full rules text

How it adds up: composite = Σ(score × weight) / Σ(weight) across measured + heuristic pillars only. Pending and data-rights-blocked pillars are excluded from both numerator and denominator. Total contributing weight = 70.0.

Caveat: 2 pillars not assessed yet; the score will recompute as the substrate fills in.
