The headline moment for Nebius Group in 2026 was not another GPU order, but the decision to buy Eigen AI for about US$643 million in cash and stock, folding its inference tooling into Nebius’s Token Factory platform. Investors who held Nebius Group from the start of the year are up 163.6%, including dividends. If you were deciding back on 1 January whether to buy, what had to be believed about contracts, power, and capital intensity before any of that news hit the tape?
On Simply Wall St, a Narrative is an investor's thesis written down: the reasoning, plus the numbers it rests on. Run those numbers and you get an estimated Fair Value.

The Argument You Would Have Been Weighing Up On Nebius Group
The shares cost US$83.7 at the start of the period. Anyone looking at Nebius Group then was really choosing between two sharply different stories that still both sounded reasonable.
The bullish narrative put Fair Value at US$97.4, 16% above the start price. It leaned on the idea that winning a US$17.4b Microsoft contract plus rapid AI demand could support revenue growth of 160.9% and a future P/E of 64.0x.
The bearish case set Fair Value at US$75, 10% below the start price. It focused on concerns that committing US$2b of capital in 2025 and targeting 1 gigawatt of power by 2026 would keep free cash flow under strain even if revenue grew 123.1% with a future P/E of 76.7x.
What The Evidence Did To The Nebius Group Argument
The Eigen AI acquisition that Nebius Group completed in June directly supported the bullish story about moving up the stack, since it pushed more inference software into Token Factory. The latest numbers presented a tougher story on profitability, with revenue at US$582.3m in Q2 2026 versus US$105.1m a year earlier, while net income shifted from a US$502.5m profit to a US$190.4m loss. Overall, the evidence pointed in both directions.
The debate centered on whether rapid contract wins and power build out would translate into durable earnings rather than just higher sales. For a different AI infrastructure stock, a reader could track a similar claim by comparing revenue to net income and margins every quarter to see whether scale is producing the profit profile that the original thesis described.
What Nebius Group’s Rally Already Assumes
Nebius Group now trades at US$237 after a 163.6% gain from the start of the year. The selected Narrative’s Fair Value sits below the current price, which frames today’s quote as rich against its own more cautious model.
That view turns on heavy spending and funding needs. To justify today’s level, a buyer would need to assume Nebius can keep financing very large data center builds without significantly affecting future returns.
"Surging capital expenditures, as evidenced by the company's commitment to $2 billion in 2025 alone and a massive multi-year plan to secure 1 gigawatt of power by 2026, are expected to drive down free cash flow and put pressure on net margins for years, particularly because profitability at the group level is not anticipated until after 2025."
