Nebius Reiterates 2026 Targets; Prepayment Trajectory Supports Funding but Valuation Still Demands Execution

What happened

Nebius management reaffirmed 2026 revenue guidance of $3.0-3.4 billion and an exit run rate of $7-9 billion, implying continued hypergrowth from current levels. The company expects connected power to reach 800 MW to 1 GW by year-end and has raised contracted power targets to 5 GW, signaling aggressive capacity expansion. Customer prepayments are projected to exceed $9 billion in 2026, with recent contracts covering 50-60% of associated infrastructure capex, which reduces near-term equity funding needs. However, the stock still trades at a premium valuation with a market cap around $54 billion and EV/EBITDA over 113x, leaving little room for commissioning or pricing slips. The article's emphasis on prepayments as the key metric is valid, but it must be weighed against the company's history of high capex, customer concentration, and reliance on timely deployment to convert contracted capacity into revenue.

Implication

The updated figures reinforce that demand for Nebius's AI capacity remains strong and that customer prepayments are funding a meaningful portion of the build-out, which supports the base case. However, the premium valuation assumes near-perfect conversion of contracted power into billable capacity on schedule, and any delay could trigger service credits or force more dilutive financing. The key checkpoints remain whether the first short-term premium capacity deal launches in Q4 2026, whether prepayments track above the $9 billion pace, and whether early-2027 Meta deployment begins on time. Until these milestones are confirmed, the risk-reward is balanced rather than asymmetric, consistent with the current WAIT rating. Investors should look for entry near the $185 attractive level or a clear catalyst proving 2027 revenue conversion before adding.

Thesis delta

The article provides incremental confirmation of Nebius's revenue and prepayment targets but does not materially alter the investment thesis. The key risks of execution slippage, customer concentration, and valuation overhang remain unchanged. As a result, the thesis stays WAIT, with no shift in conviction or price targets.
