Shares of Wayfair Inc (NYSE:W) are trading near all-time highs, which is good news for stockholders but bad news for short sellers.

One of the most notable short sellers on Wall Street, Citron Research, has been short the company since 2015 and made the case to Benzinga on Tuesday why he isn't throwing in the towel on his thesis.

"[The] company will never make money," Citron's Andrew Left told Benzinga in response to the company's first-quarter earnings report. He said the report shows management is "literally just buying revenue."

On Wednesday, Left double-downed on his case against Wayfair during CNBC's "Halftime Report" segment.

"I have [Amazon' CEO] Jeff Bezos and I have Marc Lore from Wal-Mart who have not yet competed in this space but have said 'we are going to start getting more aggressive on furniture'," Left emphasized. "They are working for me."

With that said, Left "doesn't care" where the stock is trading at right now and he is looking forward to the next 12 months when the competitive landscape will likely be very different with the potential entrance of retail's two biggest giants.

Left did acknowledge his timing on Wayfair has been a mistake, but that's "fine."
