AI investment boom squeezes stock and bond allocations; institutions say Bitcoin could become the "third leg" of traditional portfolios.

Swiss crypto asset platform Bitcoin Suisse stated in its 2026 Crypto Wealth Management Report that surging AI investments, rising government debt, and growing stock-bond correlation are eroding the risk-diversification ability of the traditional "stock-bond mix", further boosting the necessity of allocating to Bitcoin. The report projects that major U.S. cloud computing companies will exceed $800 billion in AI capital expenditure this year, potentially hitting $1 trillion by 2027. Bitcoin Suisse notes that AI investments are concentrated in a small number of tech firms, while related infrastructure construction is accompanied by large debt financing, which may further amplify concentration risks in investment portfolios. Backtesting of traditional portfolios by Bitcoin Suisse found that adding 1%, 2.5%, 5%, or 10% Bitcoin to portfolios consisting of stocks, bonds, gold, and money market assets improves both absolute returns and risk-adjusted returns. Specifically, when shifting bond allocations to BTC, the annualized yield rises from 6.2% (without BTC) to 7.2% with a 1% BTC allocation and 8.6% with a 2.5% BTC allocation. The report clarifies that Bitcoin is not a traditional safe-haven asset, but its scarcity and return drivers distinct from stocks and bonds are expected to provide a new source of diversification for investment portfolios.
