Just like for SpaceX, investors may look to ‘make room’ for AI lab IPOs. These stocks could pay the price.

**Article Body**

The prospect of high-profile AI laboratory IPOs, such as those from OpenAI and Anthropic, is beginning to reshape how institutional investors allocate capital. According to market strategists, these upcoming listings may dovetail with a seasonal tax-loss harvesting period, a combination that could pressure existing underperformers. The logic is straightforward: to "make room" for new, highly anticipated assets, portfolio managers often sell lagging positions to lock in tax benefits before year-end. This creates a dual headwind for stocks that have already disappointed this year, as they may face additional selling pressure precisely when liquidity is being redirected toward the next generation of AI pure-plays.

The market relevance here extends beyond the AI sector itself. Historically, the run-up to a marquee IPO draws capital from the broader technology complex, as funds rebalance toward the new issue. For investors, the key dynamic to watch is not just the valuation of OpenAI or Anthropic, but the ripple effect on the secondary market. If the tax-planning window coincides with a heavy IPO calendar, weaker balance sheets and speculative tech names could bear the brunt of the repositioning. While this is a natural market mechanism, it underscores how the arrival of a new asset class can implicitly reprice the value of existing ones.
