Nobody has researched this person's career yet, so founder and track record are left out of the score and of the total above.

Score = stake band (35) + founder (15) + tenure (10) + track record (15) + 12-month direction (−10…15) + filing discipline (10). An axis we have not researched is left out of the score and of the total it is shown over. Every input links to a filing or to our own research; the bands are ours.

Reported is every lot on the person's own Forms 3, 4 and 5 — direct and through trusts. Beneficial is the figure stated on the latest Schedule 13D/G cover page, which can exclude shares the person disclaims and include options exercisable within 60 days, so the two are never added together.

Earnings calls

  1. Q2 2026 Aug 12, 2026 Volozh used the call to argue that Nebius's advantage is timing rather than size: it builds capacity ahead of contracts and does not pre-sell it, so it can decide when to sell, to whom, and on what terms. He said Nebius could have sold its entire 2027 capacity at the $20-25 million per megawatt terms of the quarter's four billion-dollar deals and chose not to, holding back capacity for shorter, higher-priced business now being negotiated at $40-50 million per megawatt. He pointed to the quarter's first capacity auction, which cleared 15% above any Blackwell price Nebius had achieved, as live evidence that prices are rising rather than falling, raised the year-end contracted-power target to 5 GW, and framed the new asset-light partnership model as a way to add capacity without adding balance sheet. On competition he was unbothered: the AI cloud market is growing by tens of gigawatts a year, the hyperscalers cannot build all of it, and the rest, he said, is Nebius's to build.
