Artificial intelligence has been one of the market's most powerful investment themes over the past several years, helping propel the so-called Magnificent Seven stocks to enormous gains. While these mega-cap technology companies remain at the center of the AI trade, investors looking for the next wave of opportunities may benefit from looking at Mid-Cap ETFs.
The Invesco S&P MidCap Momentum ETF (NYSEARCA:XMMO), Vanguard Mid-Cap Growth ETF (NYSEARCA:VOT), and iShares Russell Mid-Cap Growth ETF (NYSEARCA:IWP) each provide diversified exposure to mid-cap companies that could benefit as AI adoption expands beyond the largest technology firms.
Mid-Caps Could Benefit from the Next Phase of AI Growth
The first phase of the artificial intelligence boom has been driven largely by companies building the foundational technologies behind AI. While these businesses remain well positioned, the next phase of growth will likely come from broader AI adoption as companies across nearly every industry invest in AI-powered tools to improve productivity and efficiency.
That shift could create opportunities for a wider range of businesses, many of which currently reside in the mid-cap universe. These companies may include firms providing industrial automation, electrical equipment, networking hardware, engineering services, cybersecurity, and enterprise software. Additionally, because many mid-cap companies are earlier in their growth cycle than today's trillion-dollar technology giants, they may have greater potential to grow earnings and market share over the coming years, creating even more upside potential.
Rather than attempting to identify the next individual AI winner, investors can gain diversified exposure to these emerging opportunities through mid-cap ETFs that own dozens or even hundreds of companies positioned to benefit from AI's continued expansion.

XMMO: A Momentum Strategy That Evolves with AI Leadership
The Invesco S&P MidCap Momentum ETF (XMMO) is well positioned for investors who believe AI leadership will continue to evolve. Rather than attempting to predict tomorrow's winners, XMMO follows a momentum-based methodology that automatically shifts toward mid-cap companies demonstrating the strongest recent price performance. As AI spending expands beyond semiconductors and cloud providers, the fund can naturally increase exposure to emerging leaders.
XMMO currently maintains approximately $7.18B in AUM with an expense ratio of 0.35%. The portfolio holds roughly 80 companies, with notable AI-related holdings including Sterling Infrastructure, Inc. (NASDAQ: STRL), MKS Inc. (NASDAQ: MKSI), and TTM Technologies (NASDAQ: TTMI).
The fund has generated a 21.14% total return over the past year and is up nearly 100% over the past three years, illustrating how its momentum-driven strategy has benefited from identifying emerging market leaders as investment themes evolve.
VOT: A Low-Cost Way to Own Tomorrow's Growth Leaders
The Vanguard Mid-Cap Growth ETF (VOT) offers a more traditional approach to investing in the next generation of growth companies. By tracking the CRSP U.S. Mid Cap Growth Index, the fund provides broad exposure to businesses with above-average earnings growth prospects, many of which operate in industries expected to benefit from continued AI adoption. For long-term investors, VOT offers a low-cost way to own companies that could eventually become tomorrow's large-cap market leaders.
VOT currently maintains approximately $19.92B in AUM while charging an expense ratio of just 0.05%. The portfolio contains roughly 125 holdings, with top positions including Vertiv Holdings (NYSEARCA:VRT), Western Digital Corporation (NASDAQ:WDC), and Seagate Technology Holdings.
Although VOT has delivered a more modest 2.68% return over the past year, its longer-term performance remains solid. The fund has gained 41.94% over the past three years, reflecting the strength of its diversified portfolio of growth-oriented mid-cap companies.
IWP: Broad Exposure to Mid-Cap Companies Benefiting From AI
The iShares Russell Mid-Cap Growth ETF (IWP) provides diversified exposure to established mid-cap growth companies that are already benefiting from long-term structural trends, including AI.
Unlike more concentrated strategies, IWP spreads its investments across hundreds of companies involved in software, industrial technology, and communications, making it an attractive option for investors seeking broad participation in AI's continued expansion.
IWP currently maintains approximately $20.12B in AUM with an expense ratio of 0.23%. The fund owns approximately 274 companies, with top holdings including Datadog Inc. (NASDAQ:DDOG), Snowflake Inc. (NYSEARCA:SNOW), Cloudflare Inc. (NYSEARCA:NET).
Its sector diversification and 40.87% three-year cumulative return demonstrate the fund's ability to provide broad exposure to many of the industries expected to benefit as AI adoption continues to expand, while also delivering strong long-term returns.
Which ETF Is Best?
Each of these ETFs offers a different approach to investing in the next generation of potential AI leaders. XMMO may appeal to investors seeking a momentum-driven strategy that can adapt as market leadership changes, while VOT offers a low-cost, long-term approach to owning growing mid-cap companies. Meanwhile, IWP provides the broadest diversification of the three, making it an attractive option for investors seeking balanced exposure across multiple industries expected to benefit from continued AI adoption.

Looking Ahead: What's Next for Mid-Cap ETFs Offering AI Exposure
While the Magnificent Seven are likely to remain major beneficiaries of the AI revolution, the next phase of growth may extend well beyond today's largest technology companies. As businesses across industries adopt AI-powered technologies, diversified mid-cap ETFs could offer investors an opportunity to participate in the next generation of market leaders while reducing reliance on a handful of mega-cap stocks

Four leading AI models discuss this article
"Mid-cap AI exposure via XMMO, VOT or IWP is not the obvious next leg of outperformance the headline implies given stretched valuations and recent underperformance."
The article correctly notes that AI spending is broadening beyond hyperscalers into automation, cybersecurity and enterprise software, where many mid-caps reside. XMMO’s 99% three-year return is impressive, yet its 0.35% fee and 80-stock concentration expose investors to sharp drawdowns when momentum reverses. VOT and IWP are cheaper and more diversified but have lagged the Mag7 and even the S&P 400 over the past 12 months (VOT +2.7% vs. mid-cap growth benchmark +8%). Missing context: mid-cap valuations are no longer cheap (Russell Mid-Cap Growth forward P/E ~22x vs. historical 17x) and higher-for-longer rates continue to pressure growth multiples.
If AI capex disappoints or shifts back to the Mag7 hyperscalers, these mid-cap ETFs could underperform for years; the article glosses over how many of the cited holdings (DDOG, SNOW, NET) already trade at 60-100x sales and would be hit hardest in any risk-off move.
"Mid-cap AI exposure is a high-beta play on interest rate stability, not just a thematic bet on AI adoption."
The pivot to mid-cap ETFs like XMMO, VOT, and IWP is a classic 'second-derivative' play, but it’s fraught with valuation risk. While these funds capture the 'AI-adoption' narrative, the article ignores that mid-caps are disproportionately sensitive to interest rate volatility and tighter credit conditions compared to the cash-rich Magnificent Seven. XMMO’s momentum strategy is particularly dangerous here; it inherently buys high, which risks catching the tail-end of a cyclical rotation rather than the start of a secular trend. Investors need to distinguish between companies providing actual AI infrastructure—like Vertiv in VOT—versus generic 'growth' software firms that may face margin compression if AI R&D budgets plateau.
Mid-caps are currently trading at a significant valuation discount relative to the S&P 500, offering a margin of safety that mega-cap tech—priced for perfection—simply does not have.
"The article's thesis—mid-caps will outgrow mega-caps as AI spreads—is intuitive but ignores that mega-caps own the enterprise software and cloud infrastructure layers where most AI capex actually flows."
The article conflates two separate theses: (1) mid-caps will outgrow mega-caps as AI adoption broadens, and (2) these three ETFs are good vehicles. The first is plausible but unproven—it assumes mega-caps won't capture AI's enterprise layer (they will: MSFT, GOOG, AMZN dominate enterprise software). The second is marketing. XMMO's 100% three-year return is momentum chasing, not alpha—it will revert. VOT and IWP are reasonable core holdings, but the article ignores that mid-caps are already re-rated (IWP +41% in three years isn't cheap). The real risk: if AI capex slows or concentrates further in semiconductors/cloud, mid-cap exposure becomes a value trap.
Mid-caps may already be priced for AI adoption given their 40%+ three-year returns, and the article provides zero valuation anchors (P/E, forward multiples, PEG ratios) to justify further upside versus mega-caps trading at similar or lower multiples.
"Mid-cap AI ETFs offer diversification and upside but are structurally riskier and may underperform mega-cap AI leaders in a macro downturn due to liquidity, valuation, and cyclicality."
While the article pitches XMMO, VOT, and IWP as the ‘next AI winners,’ beware: mid-cap AI exposure is vulnerable to regime shifts, liquidity frictions, and valuation resets. Momentum (XMMO) can swing sharply if AI leadership stops rotating or if growth slows, and its 0.35% fee trails performance well when volatility spikes. VOT and IWP offer broad growth exposure, but they carry higher tracking error versus sector ETFs and can be overweight in less-profitable names when AI capex retrenches. Mid-caps are more cyclical and balance-sheet sensitive; in a risk-off episode, mega-caps with pricing power may outperform. Consider blending with quality, profitability, and macro risk controls.
The strongest counter is that the AI growth story may remain concentrated in a few mega-caps with pricing power and liquidity, leaving mid-cap ETFs exposed to sharper drawdowns and tracking errors if the cycle falters.
"XMMO's momentum has been AI-driven and its valuation buffer remains underappreciated relative to liquidity risks."
Claude correctly flags the conflation of theses, but misses that XMMO's 99% three-year return stems from persistent AI-adjacent momentum (DDOG, SNOW) not yet priced into forward multiples—current 22x Russell Mid-Cap Growth P/E still sits below 2021 peaks. The real unmentioned risk is second-order liquidity: mid-caps face wider bid-ask spreads in any AI capex pause versus hyperscalers.
"Comparing current mid-cap P/E ratios to 2021 levels is misleading because the higher cost of capital makes current valuations significantly more expensive."
Grok, your focus on 2021 peaks ignores that the cost of capital has fundamentally shifted. Comparing today’s 22x forward P/E to a zero-interest-rate environment is a trap; the discount rate is now significantly higher, making those multiples far more expensive in real terms. Claude is right about the marketing fluff. These ETFs are essentially 'beta' plays on AI sentiment, not alpha-generating vehicles, and they will face brutal liquidity crunches if institutional flows reverse.
"Mid-cap valuations require significantly faster earnings growth than mega-caps to justify current multiples; the article never tests whether that growth materializes."
Gemini's discount-rate argument is sound, but it cuts both ways: if rates stay elevated, mid-cap multiples compress further—but so do mega-cap multiples. The real divergence isn't valuation; it's earnings growth. Mid-caps need 18%+ EPS growth to justify 22x forward P/E versus mega-caps at 15x with 12% growth. Nobody's stress-tested whether mid-cap earnings actually accelerate if AI adoption broadens, or if they just get crowded out by mega-cap pricing power. That's the thesis that needs proof.
"Second-order liquidity risk and concentration of AI exposure in mid-caps could trigger sharper drawdowns in risk-off regimes, unless earnings durability proves the growth story."
Grok, you're right about second-order liquidity risk in mid-caps, but I'd push further: quantify how many of XMMO's 80 holdings are AI-adjacent versus core growth, and how sensitive they are to credit tightening. The bigger risk is a risk-off regime where thinner mid-cap liquidity and higher tracking error trigger sharper drawdowns, especially with momentum exposure (XMMO). In that environment, earnings durability matters more than forward P/E theatrics.
Mid-cap AI exposure, while capturing the AI-adoption narrative, is vulnerable to regime shifts, liquidity frictions, valuation resets, and may face brutal liquidity crunches if institutional flows reverse. Earnings growth acceleration in mid-caps needs to be proven to justify current valuations.
