The global artificial intelligence (AI) boom has propelled stock markets in the US, South Korea, Taiwan, and Japan to unprecedented record highs. Driven by an insatiable investor appetite for large language model (LLM) developers, semiconductor giants, and chip manufacturers, the rally has taken a highly speculative turn as market participants increasingly turn to leverage to maximize their returns.
According to a report by the Wall Street Journal referencing Finra data, US margin debt—the capital investors borrow from brokerages to purchase equity—surged 54% year-over-year to a record $1.4 trillion.
Multiple Layers of Risk: Leveraged ETFs and Options
Market experts are raising alarms over the layers of systemic risk accumulating in the financial system. Rather than simply buying shares, institutional hedge funds and retail traders alike are pouring money into high-risk leveraged Exchange-Traded Funds (ETFs) that amplify the daily movements of underlying stocks by two or three times.
Mark Hackett, chief market strategist for Nationwide’s investment management group, warned of a dangerous “lottery mentality,” where investors use margin accounts to buy options on already leveraged ETFs, creating multiple compounding layers of risk.
“I’m fearful that we’re building unintended leverage that isn’t fully understood,” Hackett noted.
Total assets held within these leveraged funds doubled to a record $220 billion between late March and early June. To keep pace with this staggering influx of new capital, analysts estimate that leveraged funds have purchased roughly $300 billion in derivatives linked to individual stocks and major indexes since March.
The Anatomy of the Hype: The SpaceX IPO Example
The feverish market sentiment is perfectly encapsulated by the recent public listing of Elon Musk’s space exploration company, SpaceX, on the Nasdaq.
- IPO Issue Price: $135 per share
- Day 1 Surge: Jumped 19% to close at $161 amid intense FOMO (fear of missing out).
- Peak Valuation: Reached a record high of $201 per share (a 63% increase from the IPO price).
- The Correction: The speculative bubble quickly deflated, sending the stock tumbling back down to the $150 level.
As massive inflows continue to flood into high-leverage products, market observers caution that these derivative-heavy instruments are beginning to dictate the behavior of individual underlying stocks, threatening to trigger severe, unexpected market volatility.
