BofA Survey: 56% of Fund Managers Call AI Rally a Boom

nvidia amd ai-markets stocks

Key insights

  • 56% of fund managers in BofA's June 2026 survey classify the AI investment cycle as a boom phase, not euphoria.
  • Fear of missing out is the identified driver pulling new institutional participants into AI equities.
  • The boom-versus-euphoria framing implies most professional investors believe the AI rally has further to run.

Why this matters

The boom-versus-euphoria gap in institutional sentiment is a leading indicator for capital allocation decisions: fund managers who accept the boom framing are more likely to maintain or increase AI equity exposure rather than trim. The BofA Global Fund Manager Survey is one of the most widely watched institutional sentiment gauges, so a 56% boom majority can itself become self-reinforcing by validating FOMO-driven inflows from under-allocated managers. For AI founders and technical leaders, sustained institutional conviction at the boom stage means capital markets remain receptive to AI-focused growth narratives, keeping valuation multiples elevated and funding conditions favorable.

Summary

Bank of America's June 2026 Global Fund Manager Survey found that 56% of portfolio managers describe the current AI stock rally as a "boom" phase, stopping well short of the "euphoria" label. The distinction carries real portfolio weight. Boom implies momentum-driven FOMO still pulling in new participants; euphoria implies late-cycle excess that typically precedes correction. The survey found that "fear of missing out is continuing to drive the trade" in AI stocks, suggesting the dominant institutional read is that the rally retains runway rather than representing a crowded peak. Essentially: (Bank of America) BofA's monthly pulse of global fund managers shows confident but not reckless institutional sentiment around AI equities. - 56% of respondents placed the AI cycle in "boom" territory, the largest sentiment category. - FOMO remains the primary mechanism pulling new capital into AI names. - The boom-versus-euphoria distinction is the survey's core framework for reading cycle positioning. For now, the professional consensus leans toward continued AI equity outperformance, though survey sentiment reflects perception, not underlying fundamentals.

Potential risks and opportunities

Risks

  • If the next BofA monthly survey shows the 'euphoria' category surpassing 50%, institutional risk managers at large allocators could trigger coordinated AI equity trimming within a single reporting cycle
  • Fund managers who increased AI exposure on documented FOMO grounds face amplified drawdown risk if earnings from major AI names disappoint in coming quarters, since their positioning was sentiment-driven rather than fundamental
  • The published 56% boom consensus could attract short sellers who interpret dominant institutional crowding as a contrarian signal against AI equity names

Opportunities

  • ETF and index providers with AI equity products stand to see incremental inflows from institutional managers still under-allocated relative to peers who have already acted on FOMO
  • Active managers who can identify the precise boom-to-euphoria sentiment inflection in future BofA surveys could outperform by rotating selectively out of AI names ahead of that shift
  • AI-focused private companies targeting institutional investors benefit from the boom consensus, as it supports elevated valuation benchmarks and lowers friction for growth-stage funding rounds and secondary transactions
