Reddit is trading at $180.52, +14.17%, after S&P Dow Jones Indices announced its S&P 500 inclusion.
- Reddit will replace AvalonBay Communities before trading opens on August 18, 2026.
- Anticipated buying by passive index funds is driving the rally; JPMorgan estimates funds may need approximately 16.7 million shares, nearly three times average daily volume.
- Broader markets are broadly flat, making the index addition the clear catalyst.
