Gregory Fenelon presents himself on LinkedIn as a seven‑year JPMorgan veteran and founder of Wintellex, yet Bloomberg shareholder registries based on recent SEC filings show him as the apparent ultimate owner of $14bn in shares across 20 U.S. companies. Those stakes make him the seventh‑largest holder of Hyatt Hotels, sixth at Take‑Two Interactive, third at Celsius, and the single biggest shareholder in TKO Group, owner of the UFC franchise.

Fenelon’s online footprint is minimal: a single LinkedIn post, a verified Government ID, and a Bold.pro profile that lists a past role as an equipment operator. His company Wintellex claims a $1.2bn raise at a $20bn valuation, but its website links lead nowhere. Both Wintellex and Starlite Capital list the same virtual office at 1910 Pacific Ave Suite 2000 in Dallas, Texas. Harvard Business School confirmed Fenelon never attended its executive programs, and a call to the Dallas address went unanswered.

Research firm Gordon Haskett labeled the Starlite and Fenelon Opportunity Fund entities “completely bogus,” noting that recent 13G filings conflict with an earlier 13F and that the funds appear to have no real operations. The FT contacted Starlite, Wintellex, and Fenelon without response; JPMorgan declined comment.
