Opendoor’s stock had already risen over 16% during regular trading on Wednesday, driven by an upbeat new home sales report. Data showed robust growth in new single-family home sales:

• The seasonally adjusted annualized rate reached 800,000 units in August,
• Up 20.5% month-over-month and 15.4% year-over-year.

However, Jane Street has faced past controversies, including allegations of market manipulation in India and political affiliations tied to one of its co-founders. While these incidents have drawn scrutiny, they have not undermined its standing in the quantitative trading industry.

Notably, Opendoor’s stock has already gained over 280% year-to-date. Jane Street’s newly disclosed stake may further intensify short-term speculative interest in the stock, which has recently attracted attention from retail and meme stock traders. Investors should remain cautious about the risks associated with sentiment-driven volatility.
