Leveraged ETFs tied to IREN Ltd. (IREN) surged as much as 40% on Monday, dramatically outperforming the underlying stock after the AI infrastructure company raised its long-term cloud revenue outlook and unveiled $2.8 billion in new customer contracts.

The rally was led by:

– Tradr 2X Long IREN Daily ETF (IREX) — up about 40%

– Defiance Daily Target 2X Long IREN ETF (IRE) — up nearly 40%

– Leverage Shares 2X Long IREN Daily ETF (IREG) — also gaining close to 40%

The move illustrates how single-stock leveraged ETFs can magnify upside when a high-beta AI infrastructure stock experiences a sharp re-rating.

Why These ETFs Are Outperforming

All three ETFs seek to deliver 200% of IREN's daily return through derivatives rather than direct stock ownership.

When IREN jumped roughly 20%, the ETFs responded with gains approaching 40%, consistent with their daily leverage objective.

However, these funds are designed for short-term tactical trading, not long-term investing. Because leverage resets every day, returns can drift significantly from two times the stock's cumulative performance over weeks or months, particularly during volatile trading.

That makes them attractive for traders with a high-conviction, short-term view but considerably riskier than owning the underlying shares.

AI Infrastructure Is Fueling the Trade

Monday's surge was triggered after IREN boosted its 2026 annualized AI Cloud revenue target to more than $4 billion, from $3.7 billion previously.

The company also disclosed $2.8 billion of signed multi-year AI cloud contracts, with roughly 85% of the new revenue target already backed by agreements.

The announcement reinforced investor confidence that demand for AI compute infrastructure remains exceptionally strong.

IREN counts companies including Microsoft Corp (MSFT), NVIDIA Corp (NVDA), Perplexity, Together AI, Figure AI, Fluidstack, Fireworks AI and Hume AI among its AI ecosystem customers, while management said demand continues to exceed available computing capacity.

The Fundamentals Behind the Bullish ETF Move

For leveraged ETF traders, the announcement wasn't simply about higher revenue guidance.

Several fundamentals strengthened the investment case:

• Nearly 45% of GPU infrastructure spending tied to recent contracts will be funded through customer prepayments, reducing capital requirements.
• AI cloud capacity is expected to increase from 480 MW this year to 1.2 GW by 2027, signaling aggressive expansion.
• Approximately 85% of projected 2026 AI cloud revenue is already contracted, improving earnings visibility.
• The company ended June with $7.6 billion in cash, giving it significant flexibility to fund future growth.

These developments suggest that the stock's rally was driven by improving business fundamentals rather than speculative momentum alone — a key consideration for leveraged ETF traders.

What ETF Investors Should Watch

The three bullish IREN ETFs remain among the most aggressive ways to express a view on AI infrastructure.

If enthusiasm around AI cloud build-outs continues, these products could continue to outperform the underlying stock on strong up days. Conversely, any pullback in IREN would also be amplified roughly twofold, making risk management especially important.

With IREN's next earnings update expected on Aug. 27, traders will be watching whether the company can translate its expanding AI contract backlog into accelerating revenue growth. This outcome could determine whether the current rally in leveraged IREN ETFs has further room to run.
