Reddit inclusion in S&P 500 index

Overview

Reddit Inc. joined the S&P 500 index on August 18, 2026, replacing AvalonBay Communities following its merger with Equity Residential to form Vivmark Residential.

Following the inclusion, Reddit’s stock has seen significant movement, rising 365% since its initial public offering. This follows an earlier surge of 11% to 15% in extended trading driven by anticipated demand from passive investment funds and ETFs. Analysts at JPMorgan previously estimated that these funds would need to acquire approximately 16.7 million shares.

Despite strong financial performance—including a 61% year-over-year revenue increase and a 178% rise in earnings per share—the company faces ongoing challenges. These include concerns regarding declining daily active users in the U.S. and potential traffic disruptions caused by AI-driven search tools.

Reddit’s inclusion coincides with a period of high market valuations. The S&P 500 is currently trading at levels comparable to the period preceding the Dot-Com Bubble, according to the Shiller CAPE ratio. As of late August 2026, the CAPE ratio has reached 42.2, the highest level since the 1999 dot-com peak of 44.2. This metric indicates the market is significantly more expensive than the long-term average since 1990, which is approximately 27.

Economists from the European Central Bank have noted that these high valuations in the US and Euro area reflect intense investor enthusiasm regarding artificial intelligence. While some view this as a rational bet on transformative technology, others warn of a potential market correction similar to previous technological revolutions, such as the railway boom or the internet surge of the 1990s.
