① Signs indicate U.S. retail investors are regrouping across multiple "strongholds," planning to "pull off something big" with a Meme stock that went viral four years ago...  

② Over the past week, retail traders exchanging U.S. stock insights on social media have revived online home-flipping platform Opendoor.OpenDoor Technologies, Inc.(OPEN.US)  

Evidence suggests U.S. retail investors are rallying across key platforms, preparing for a major play with a Meme stock that exploded in popularity four years ago...  

Until recently, shares of U.S. instant home-trading platform Opendoor were largely considered worthless. But in the past week, retail traders discussing stocks on social media have breathed new life into it.  

According to Sahm data, Opendoor has surged over 90% since Monday's open. Accompanying this rally are explosive increases in call option volumes and social media buzz...  

Tom Bruni, VP of Community & Editor-in-Chief at Stocktwits (a prominent U.S. social media platform for investment discussions), noted that page views for Opendoor's ticker on Stocktwits surged 400% from Monday to Tuesday. Wednesday's growth appeared poised to double that rate. Discussions about Opendoor have spiked noticeably across multiple platforms.  

To Bruni, Opendoor's sudden rise proves the "Meme stock" phenomenon never died—it fueled the 2021 frenzy in speculative stocks like GameStop and AMC, staging an epic "retail vs. Wall Street" battle.  

"It's almost the same pattern. Meme stocks didn’t disappear; they just manifest differently based on market conditions," Bruni stated.  

Notably, heated discussions are unfolding on Reddit's WallStreetBets forum—the former epicenter of retail trading. Many investors have posted screenshots of their Opendoor positions on WallStreetBets and similar platforms.  

Meanwhile, record call option activity for Opendoor on Wednesday further propelled the stock. Preliminary data from Dow Jones Market Data shows ~560K call contracts traded that day—as trading volume for Opendoor shares also hit all-time highs.  

Why Retail Investors Are Piling Into Opendoor?

Opendoor closed at $1.49 Wednesday. FactSet data shows this remains far below its 2021 peak above $30.  

Public records indicate Opendoor Technologies Inc. operates a digital residential real estate platform. It aims to transform home transactions through software, data science, and operational expertise.  

Per FactSet, Opendoor hasn’t reported an annual profit since going public via SPAC in December 2020—though its stock rose modestly in May after Q1 losses beat expectations.  

Bruni observed the true explosion of interest coincided with a post by Eric Jackson, founder of Canadian micro-hedge fund EMJ Capital, on X. Jackson expressed bullish views, predicting Opendoor "could exceed $80 within a year or two."

Jackson acknowledged retail interest fueled the rally, as investors hunt for the next big opportunity:  
"Most retail investors moved on from the Magnificent Seven long ago. They were early adopters of quantum computing stocks. There’s a hunger to find the next moonshot." 

Notably, Opendoor isn’t 2025’s first speculative stock to take flight. As Cailian recently reported, so-called "penny stocks" (which include Opendoor by some definitions) are seeing sustained trading spikes.  

A Goldman Sachs report revealed stocks trading below $1 accounted for over 47% of U.S. equity volume on June 12—the highest share on record.
