GDP Over Market Cap: Amundi Takes Aim at Vanguard’s All-World Empire as ETF Hits Fresh Peak

Amundi launches a GDP-weighted global equity ETF directly competing with Vanguard's FTSE All-World fund, offering an alternative to US tech-heavy market-cap weighting.

The debate over how to weight a global equity portfolio is suddenly heating up. Just as the Vanguard FTSE All-World UCITS ETF touched a new all-time high of €163.56 on Friday, Amundi has launched a directly competing fund that swaps market capitalisation for economic output as its guiding principle. The timing is no coincidence.

On the Thursday before, the Vanguard fund had closed at €163.16. Over the past twelve months it has gained 27.15%, and year-to-date it is up 11.77%. With a total expense ratio of 0.19% and a tracking error of just 0.05 to 0.08 percentage points, the product remains an efficiency benchmark in its own right. But Amundi is betting that investors want a different kind of exposure to global stocks.

A rival built on GDP weighting

On 28 May 2026, Amundi listed the FTSE All World GDP-Weighted UCITS ETF Acc, the first Europe-domiciled equity ETF to weight countries by their gross domestic product rather than by stock market value. The universe is identical to Vanguard’s — large and mid-cap equities from developed and emerging markets — but the allocation logic is radically different.

Under a market-cap approach, the biggest companies by market value dominate. That has led to a heavy concentration in US technology giants: Nvidia accounts for 4.66% of the Vanguard index, Apple for 3.90%, and Microsoft for 3.02%. A GDP-weighted strategy tilts the portfolio toward countries whose economic heft is larger than their stock market footprint. The US share shrinks, while Europe and emerging markets gain weight. For investors worried about the ballooning US tech valuation risk, the appeal is immediate.

Two philosophies, one market

Neither ETF is a simple clone. Vanguard uses physical replication with optimised sampling — buying a representative subset of stocks to keep costs low and tracking tight. Amundi’s newcomer does not challenge that operational efficiency; rather, it shifts the competition to the index methodology itself.

Market-cap weighting has been a clear winner during the US tech boom, but GDP-weighting has historically outperformed in other market cycles. The new fund offers a structural hedge: if US equities stumble or the dollar weakens, a GDP-based portfolio could fare better. The trade-off is greater exposure to politically and currency-volatile markets, which can introduce a different kind of risk.

Size still matters

Vanguard’s entrenched position gives it a formidable advantage. At the end of April 2026, the fund held $65.96 billion in assets under management, with the accumulating share class alone worth $41.76 billion. That scale translates into deep liquidity and low trading costs — particularly important for large savings plans and institutional orders.

Amundi’s launch is nevertheless a conceptual test for the passive investing dogma. The number of ETF investors in Germany has doubled recently, and globally diversified funds are the most popular category. The Vanguard fund currently trades about 7% above its 50-day moving average, signalling ongoing momentum. Whether the GDP-weighted alternative can capture meaningful flows will depend on how US technology valuations evolve. If the wind shifts, Amundi’s methodology could suddenly look far more compelling than it does today.
