Mag 7 Drives Record Bullish Call Buying As AI Infrastructure Demand Accelerates

The Magnificent Seven stocks are capturing outsized options flow as traders position for sustained AI capex cycles. Over the past few days, $249M in bullish single-leg call premium landed across the index, concentrated heavily in NVDA, TSLA, and AAPL. This is not passive rebalancing; it reflects active conviction that the AI infrastructure wave has legs.

The narrative is hardening around AI memory constraints. In early May, the CEOs of MSFT, META, GOOGL, AMZN, and AAPL all remarked on earnings calls that memory is constrained and will remain so for the foreseeable future. That bottleneck is not a cyclical hiccup; it signals multi-year capex commitments. Meanwhile, the market still prices MU at a mere 7x earnings despite being a primary beneficiary of this dynamic. NVDA traded near its $5.5T market-cap milestone, buoyed by reports that the U.S. government approved H200 chip sales to ten Chinese companies, easing China-trade uncertainty temporarily.

Chips, foundry, and data-center operators all benefit from this structural demand. AVGO has seen strong call flow as well. The Cisco earnings beat earlier in the week validated that AI networking demand is broadening beyond chips into switches, optics, and scale infrastructure. This suggests the capex wave is widening and maturing, pulling more subsectors into the trade.

The risk is that valuations already price much of this goodness in, and any miss on monetization timelines could trigger sharp mean reversion. Skeptics note that margin expansion from AI services has been slower than expected, and some large cloud players are still in heavy investment mode rather than harvest mode.
