— Why it moved
Why SNBR Stock Doubled Today — June 17, 2026
Sleep Number filed Chapter 11 five days ago. Today, with a delisting notice on the tape, the stock quadrupled intraday on 892 million shares.

What moved SNBR stock
Sleep Number is Chapter 11 equity — the company filed for bankruptcy on June 12, and June 17 brought a Nasdaq delisting notice. No good news anywhere. What moved it was a bankruptcy squeeze: borrow rates spiked among the most of any liquid name that day, about 28% of the float was short, and everyone was positioned for zero.
The mechanics
When a crowded short gets pressed in a $5M-cap stock, covering feeds the move. The stock opened flat at $0.18 with no gap, then 892M shares traded against a 21.5M float — turned over roughly 40 times, all of it intraday.
SNBR by the numbers
The alert window
Stock Pulse alerted at 10:03 AM at $0.37, already double the prior close; the peak $0.74 printed at 11:27 AM — one hour and twenty-four minutes of window, worth 101% to a real-time reader. Then the squeeze let go.
How SNBR's move ended
The collapse was as fast as the run: the close was $0.39, 5% above the alert, with three quarters of the spike gone — the classic squeeze shape. This is Chapter 11 equity, and in most bankruptcies the common stock is wiped out, with the delisting already in motion.
The tell: a squeeze in bankrupt equity has a hard ceiling — once the shorts finish covering there is no buyer left, and the give-back runs nearly to the starting line.
