AI investors have woken up to the bond market’s warning signs

The surge in AI-related equities has been one of the defining market stories of the past two years, but the bond market has been sending a different signal. Yields on longer-dated government debt have climbed even as stock investors pile into AI names, a divergence that historically has not persisted indefinitely. Rising yields raise the discount rate applied to future corporate earnings, which matters most for growth companies whose valuations rest on profits expected years from now.

For readers, the takeaway is not that AI is overhyped or that bonds are "right." It is that two of the world's largest markets are pricing different outlooks — equities implying durable earnings growth, bonds implying stickier inflation, heavier government borrowing, or both. When those views diverge, something usually gives.

What to watch: whether long-term yields continue rising, whether AI-linked earnings actually arrive on schedule, and whether credit spreads stay calm. None of these alone signals a turn, but together they frame the risk backdrop investors are now navigating.
