This $10 Billion ETF Owns the Companies Wiring America’s $68 Billion Data Center Boom
First Trust RBA American Industrial Renaissance ETF (AIRR) with about $10B in assets is highlighted as a concentrated proxy for hyperscaler data center capex. The article cites holdings such as Comfort Systems (FIX), EMCOR (EME), Sterling Infrastructure (STRL), and Powell Industries (POWL), noting strong YTD gains and recent pullbacks, plus EMCOR’s $17.14B remaining performance obligations. It also discusses a September rebalance risk.
How this was made

The 30-second read
Why it matters
The article frames AIRR’s next 12 months around hyperscaler 2027 capex guidance and flags a September rebalance that could force selling of top performers due to small/mid-cap mandate constraints.
Market read
Traders may treat AIRR and its top contractor holdings as a leveraged expression of hyperscaler capex expectations, with an additional mechanical catalyst from the upcoming September rebalance.
What to watch
The article emphasizes capex guidance from four mega-cap tech firms, but does not quantify how much of each contractor’s backlog is directly tied to those hyperscalers versus broader industrial demand.
Background
AIRR tracks the Richard Bernstein Advisors American Industrial Renaissance Index and is positioned as a concentrated proxy for wiring, cooling, and powering hyperscaler campuses.
Ticker impact
Comfort Systems USA (FIX) is cited as AIRR’s top data-center exposure at 4.18%, up 85% YTD but pulled back sharply last month.
Short-term sensitivity to any AIRR index/rebalance-driven demand changes.
The text links FIX’s market-cap growth to potential mandate breach and notes both strong YTD performance and a recent pullback.
EMCOR (EME) is cited as AIRR’s 3.54% holding with $17.14B remaining performance obligations, plus a recent pullback.
Backlog strength may cushion downside, but AIRR turnover could still create flow-driven volatility.
The article provides a concrete backlog number and ties EME’s role directly to hyperscaler capex conversion into work.
Sterling Infrastructure (STRL) is cited as AIRR’s 3.96% holding, up 80% YTD and down nearly 19% in the past month.
Potential two-way volatility as investors reassess the durability of backlog conversion after the pullback.
The article quantifies both the YTD strength and the recent decline, framing the next 12 months as a live question.
Powell Industries (POWL) is cited as AIRR’s 1.83% holding, up 92% YTD but down 13% over the past month.
Flow-driven volatility possible, though impact may be smaller than FIX/STRL/EME due to lower weight.
The text provides both weight and quantified performance, and positions the fund as a hyperscaler capex proxy.
Market effects
Highlights hyperscaler data-center capex as the key driver for electrical and mechanical contractors, implying sector beta to large-cap AI infrastructure spending.
Primarily US industrials exposure via contractors and related backlog dynamics.
US hyperscaler capex guidance is treated as the single macro input, which can spill into global industrial construction sentiment.
Counterpoint
The rebalance risk may be overstated for price impact if the fund can replace removed names with other contractors still benefiting from hyperscaler capex.
