On 19 May 2026 GameStop reported a 6.55% economic stake in eBay assembled for $9.95 million of cash. The position comprises 25,000 directly held shares and a strip of American-style put\/call option pairs referencing 29,078,699 shares, with The Toronto-Dominion Bank as counterparty, with strikes ranging from $84.74 to $114.96, expiring 23 February 2028. I define the synthetic toehold ratio \u03c1 as cash outlay divided by notional exposure and the leverage multiple L as its inverse. At post-rejection spot, \u03c1 = 0.295% and L = 339\u00d7, well above the leverage available from direct-stake toeholds surveyed in the prior literature. I situate the structure between earlier control-related derivative cases (CSX, Porsche-VW, Schaeffler-Continental) and argue it partially dissolves the toehold puzzle of Betton, Eckbo, and Thorburn (2009). The HSR-conditional cash-settlement feature supports the bidder's disclaimer of beneficial ownership under Rule 13d-3(d)(1)(i), the legal hook the GameStop 13D explicitly invokes. Second, I formalize the reflexive deal value channel in reverse-acquirer cash-stock offers. GameStop's share price fell 20.4% between announcement and 22 May 2026, taking the marked-to-market offer from $125.00 to $112.23 per eBay share. Headline-anchored arbitrage spreads materially overstate the deal's economic content. Under the unaffected close of $85.62 as the failure value, the headline offer implies a completion probability of 76.5% on 22 May, while the marked-to-market value implies an impossible 113.2%. The impossibility of a probability below 100% under the marked-to-market value indicates that the market is not valuing the offer at its marked-to-market level, consistent with anchoring on the headline price, an increase in eBay's standalone value, or the possibility of a bid bump.<\/jats:p>","DOI":"10.2139\/ssrn.6821540","type":"posted-content","created":{"date-parts":[[2026,7,29]],"date-time":"2026-07-29T13:36:35Z","timestamp":1785332195000},"source":"Crossref","is-referenced-by-count":0,"title":["Synthetic Toeholds and Reflexive Deal Value: The GameStop-eBay Bid, May 2026"],"prefix":"10.2139","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-8477-9393","authenticated-orcid":true,"given":"Boon Chuan","family":"Lim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"78","container-title":[],"original-title":[],"deposited":{"date-parts":[[2026,7,29]],"date-time":"2026-07-29T13:36:35Z","timestamp":1785332195000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ssrn.com\/abstract=6821540"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"URL":"https:\/\/doi.org\/10.2139\/ssrn.6821540","relation":{},"subject":[],"published":{"date-parts":[[2026]]},"subtype":"preprint"}}
