Nebius Group came into this print on a tear, with the stock up strongly over the past month, yet the immediate reaction was a modest 1.6% drop to about $255. That small pullback sits awkwardly against what Q2 actually shows. Revenue reached $582.3m, and management highlighted an annualized run rate near $3.0b for the core AI cloud business.

The headline is simple: Nebius is pouring money into capacity and still produced a 41% adjusted EBITDA margin in the quarter. The rest of the earnings story is about how long that blend of heavy spend and high profitability can hold.

Nebius Bull Case: Capacity, Contracts And Margin On Track

Bulls argue Nebius can be a full stack AI infrastructure provider that turns massive GPU and datacenter spend into durable, profitable capacity. Q2 goes a long way toward proving that is possible at an operating level. Revenue of US$582.3m is now almost entirely AI cloud, and an annualized run rate near US$3.0b shows that capacity is being monetized, not just built.

The thesis also leans heavily on high value multi year deals and upfront funding. Nebius signed four AI cloud contracts in Q2, each above US$1b in total value, with yields of US$20m to US$25m per megawatt and 50% to 60% of capex paid upfront. That directly supports the claim that customer prepayments can fund growth. A 41% adjusted EBITDA margin, with Nebius AI cited around 50%, indicates that at current scale, the blend of heavy capex, software stack and pricing can still produce strong profitability.

Nebius Bear Case: Cash Hunger And Capital Strain Resurface

Bears argue Nebius Group is a capital hungry AI cloud builder that will struggle to turn huge spend into durable, cash generative economics. Q2 gives their thesis fresh support on several fronts. Capex of about US$5.7b in the quarter and reiterated full year plans of US$20b to US$25b indicate that free cash flow is likely to stay under pressure. Operating cash flow of roughly US$2.3b relies heavily on more than US$9b of expected 2026 customer prepayments, which supports concerns that funding leans on counterparties rather than internally generated cash.

The capital structure also moved in the direction bears feared. Nebius issued 12.7m new Class A shares for roughly US$2.8b and added a US$775m asset backed facility. Management itself highlighted that higher interest rates could erode margins over multi year deals. This aligns directly with the bear case on rate sensitivity and leverage risk.

After sharp swings in profitability, heavy capex and fresh leverage, it is worth asking if this is only the visible risk. Review the risk analysis for Nebius Group which shows 4 important warning signs.
