RDDT Stock Plunges After Hours On S&P 500 Exclusion: But Wells Fargo Forecasts $550M AI Deal Jackpot

ZivFin Analysis2026.06.05

What Happened

RDDT stock plunged more than 20% in after-hours trading following its exclusion from the S&P 500 index, a significant move that underscores the challenges the company faces in maintaining investor confidence. This exclusion is particularly notable as the S&P 500 is often seen as a benchmark for the broader market, and being removed can lead to a loss of visibility and liquidity for affected stocks. The news comes at a time when the S&P 500 itself is experiencing a downward trend, reflecting broader concerns about economic growth and corporate earnings.

The decision to exclude RDDT from the S&P 500 follows a recent trend where several high-profile stocks have been reassessed based on their performance and market capitalization. The timing of this announcement coincides with Wells Fargo's optimistic forecast regarding a potential $550 million deal focused on AI applications for Reddit's data, suggesting a disconnect between the company’s core business potential and market perception.

Why It Matters

The immediate impact of RDDT's exclusion from the S&P 500 is a sharp decline in its stock price, reflecting a loss of confidence among investors. Stocks in the S&P 500 generally enjoy higher trading volumes and media coverage, which can lead to increased investor interest. The exclusion could limit RDDT's access to institutional investors who often track index performance closely. As a result, the stock's fall could be interpreted as a broader market sentiment reflecting skepticism about the company's immediate prospects.

Fundamentally, the exclusion raises questions about RDDT's stability and future growth potential, especially in light of Wells Fargo's forecast. Analysts see the potential $550 million AI deal as a significant opportunity for RDDT, suggesting that while the immediate news is negative, the company could pivot toward a more promising direction if it successfully capitalizes on the AI trend. This dual narrative—declining stock performance coupled with potential business growth—creates a complex backdrop for the stock's future.

Market Impact

The fallout from RDDT's S&P 500 exclusion is likely to influence not just its stock but also the performance of related sectors. The tech sector, particularly companies involved in AI and data analytics, could see a mixed reaction as investors reassess their positions. For instance, stocks like GOOGL, which are heavily invested in AI, may be viewed favorably in contrast to the uncertainty surrounding RDDT.

The S&P 500 index itself is witnessing a broader decline, with many stocks feeling the pressure of rising interest rates and inflation concerns. This context affects market sentiment significantly, as traders are increasingly cautious. In the immediate term, RDDT's struggles could also lead to a reevaluation of other tech stocks that are similarly positioned but not yet facing exclusion from major indices.

What Traders Are Watching

Active traders are closely monitoring RDDT's response to the S&P 500 exclusion, particularly how the stock behaves in the coming days after this sharp sell-off. Key price levels are in discussion, as traders look for signs of stabilization or further declines. The question on traders' minds is whether RDDT can demonstrate resilience in light of Wells Fargo's AI deal forecast.

Market participants are also observing broader trends in the S&P 500. A breakout above recent resistance levels would suggest a potential recovery, while a rejection at these levels could indicate further bearish sentiment. The overall market sentiment remains cautious, with traders particularly focused on upcoming economic data releases that could influence the S&P 500's trajectory.

What Comes Next

Looking ahead, the market will be closely watching for news related to RDDT's potential AI deal, with any updates likely to sway investor sentiment significantly. Additionally, upcoming earnings reports from other major companies in the tech sector could provide context for RDDT's performance and the overall health of the S&P 500.

In a bullish scenario, RDDT could rally if the AI deal progresses and shows promise for significant revenue generation. Conversely, a bearish scenario would require further negative trends in the S&P 500 or disappointing earnings from major tech players. The next test for the S&P 500 comes in the wake of anticipated economic data releases — until then, the current bearish trend remains the dominant force.
