RH claims the top spot on the June 15, 2026 short squeeze leaderboard with a perfect Tapeboard score of 100, driven by 60.5% short interest as a percent of float and 6.65 days to cover at a 0.4% borrow fee (IBKR). GRPN follows at score 99.7, distinguished by the highest float utilization on today's board at 64.6%, while LCID stands alone as the only name with a borrow fee above 10% — its annualized borrow cost is 32.8%.

June 15, 2026 Top 25 Short Squeeze Candidates

Top Setups on June 15, 2026 — Five Names in Focus

1. RH — Squeeze Score 100

RH leads the board with a perfect squeeze score of 100 and the highest short interest on today's list at 60.5% of float. Float utilization is 41.1%, meaning more than two-fifths of available shares are currently on loan to short sellers. Days to cover is 6.65 — shorts need nearly seven average trading sessions to fully exit at current volume. The borrow fee of 0.4% (IBKR) is low, indicating supply is adequate for now, but a name with 60.5% of float sold short has limited runway before availability becomes a constraint. This is a high-SI, moderate-cost setup where the structural fuel is already loaded: if buy-side demand accelerates or lendable supply contracts, covering pressure concentrates against a very crowded short book with a six-plus-day exit window.

2. GRPN — Squeeze Score 99.7

GRPN scores 99.7 and carries the highest float utilization on today's leaderboard at 64.6% — nearly two-thirds of its entire float is currently on loan to short sellers. Short interest stands at 56.3% of float, the borrow fee is 1.0% (IBKR), and days to cover is 5.75. The 5-day momentum reading of +7.85% is the critical differentiator: when a name with 64.6% float utilization is already moving higher, short sellers are absorbing mark-to-market losses in real time. If buy-side pressure sustains, covering demand must clear through a 5.75-day exit window — there is no quiet route out for a position this size.

4. NTLA — Squeeze Score 85.1

NTLA scores 85.1 with 43.8% short interest as a percent of float and days to cover of 6.54. Float utilization is 36.2% and the borrow fee is 0.4% (IBKR). The 5-day momentum of +10.6% is the second-highest among today's top five, meaning the stock has been moving higher against an already-heavy short position. At 43.8% short interest and a 6.54-day cover window, any development that forces covering runs into a multi-session exit constraint where shorts cannot quietly reduce exposure. If sustained buying continues to pressure borrow availability, fee rates will rise and add carrying-cost pressure on top of existing mark-to-market losses.

6. TRIP — Squeeze Score 80.3

TRIP registers 80.3 with 33.8% short interest and the longest days-to-cover reading among today's top five at 9.13. Float utilization is 28.9% and the borrow fee is 0.4% (IBKR). No 5-day momentum data is available, but the threshold flag indicates that recent tape has been dominated by short-side volume — the short position is being maintained or built into, not unwound. A 9.13-day exit window means shorts cannot meaningfully reduce their position over a few sessions without their own covering contributing to upward price pressure; if buy-side flow returns to the name, the exit math turns against them.

7. AI — Squeeze Score 80.2

AI (C3.ai) scores 80.2 with 36.9% short interest and days to cover of 9.94. Float utilization is 37.7% and the borrow fee is 0.3% (IBKR), among the lowest on the board for a name with this level of short positioning. The 5-day momentum of +4.1% is modestly positive. The low borrow cost reflects current availability, not a permanent condition — at 37.7% float utilization, any narrowing of the lend pool would move the fee rate sharply. With just under 10 days to cover, the exit window alone ensures that covering demand cannot be absorbed without price impact once it begins to build.

Stocks Flagged on the FINRA Threshold List

The "T" column in the table marks securities appearing on the FINRA threshold list, which identifies names where short-side volume exceeded 50% of total reported consolidated volume on a sustained basis in recent trading sessions. A threshold listing is a pressure gauge, not a trigger — it signals that short-side order flow has been dominant in the tape, a condition commonly associated with tightening borrow availability and elevated forced-buy-in risk from broker-dealers. Twenty-one of the 25 names on today's leaderboard carry the flag. Full methodology and update criteria are documented at /methodology/short-squeeze-score.

How the Tapeboard Squeeze Score Is Built

The Tapeboard squeeze score weights five data inputs: 35% short interest as a percent of float (FINRA), 25% borrow fee (IBKR stock-loan availability data), 20% float utilization, 15% days to cover (Schwab volume data), and 5% 5-day price momentum (Schwab). All raw data is sourced exclusively from FINRA, IBKR, Schwab, and SEC filings. Complete weighting details, recalculation cadence, and edge-case handling are documented at /methodology/short-squeeze-score.
