Zoom's quarterly Anthropic gain runs 25 times its own revenue increase

The two marks imply nearly the same share of Anthropic. At the start of 2026, $1.27 billion against a $380 billion valuation works out to 0.334 percent of the company ^[1]; at the end of July, $3.13 billion against $965 billion is 0.324 percent ^[2]. So the $1.61 billion gain ^[4] is the price of Anthropic moving, not Zoom buying more of it. The cryptobriefing.com report does not state Zoom's ownership percentage, so both figures are implied by the marks it does give ^[13].

On cost, $3.13 billion against $97 million of outlay is about 32 times money ^[3]. Cut the mark in half and Zoom is still at roughly 16 times ^[4].

The gain is large against the operating line. Revenue of $1.24 billion at 5.5 percent growth implies a year-ago quarter of $1.175 billion, so Zoom added about $64.6 million of revenue year over year ^[5]. One quarter of Anthropic appreciation is roughly 25 times that ^[6].

That share of enterprise value implies a Zoom enterprise value between $24.1 billion and $31.3 billion, depending on which end of the estimate you use ^[8]. The pre-announcement close, before the 9.9 percent move, was $101.56 ^[11].

Anthropic's revenue was running at about $10.9 billion annualised as of the second quarter of 2026 ^[10]. The $965 billion valuation is roughly 89 times that ^[9], and Anthropic's revenue is about 2.2 times Zoom's own annualised run rate ^[10]. Amazon and Alphabet have each made multi-billion-dollar commitments to Anthropic ^[11], and the same report describes both as customers as well as investors ^[10].

If Anthropic lists near a trillion dollars and Zoom sells into the public market, the gain converts to cash and the July mark was conservative. If the private price compresses before a listing, Zoom gives back a number several times its annual revenue growth without ever touching cash. The third case is the one I would weight most heavily: Zoom holds through the listing, the stake becomes a publicly quoted line, and Zoom's shares trade partly on Anthropic's reported numbers. The counter-thesis is a decent one. Zoom has been building Claude integrations into its own products ^[12], the lab has revenue at scale, and against $97 million of cost ^[1] Zoom cannot lose money on the position. I would drop the caution if Zoom sold a tranche anywhere near the July mark.
