XRPN Shorts Pay 500% to Borrow as Index Odds Shorten

XRPN (Evernorth Holdings) is a newly-listed stock where the borrow market tells a more dramatic story than anything else on the tape this week: short sellers are paying annualised rates above 500% to maintain positions while two large institutional holders sit nearly immovable on the register.

The lending market is about as tight as it gets for a stock of this size. Cost to borrow reached 662% earlier in the week before easing to around 502% by Thursday, still an exceptionally elevated rate that makes sustained short positioning expensive to run. Availability has tightened sharply over the past seven days, dropping roughly 73% to leave only about 9.7% of shares still available to lend relative to the stock already on loan. Earlier this week, on October 20, availability hit 0.12%, effectively zero, meaning the entire lending pool was lent out simultaneously. That extreme has since relaxed somewhat, but the borrow market remains very tight. The stock is down 2.5% on the week and nearly 3% on the day, suggesting shorts are active despite the cost, not capitulating.

Options positioning reads as decidedly bullish relative to recent history. The put/call ratio of 0.32 sits near the low end of its 52-week range, which spans from 0.28 to 0.52. A week ago the PCR was running at 0.52, the annual high, and it has compressed sharply since. That shift from maximum defensiveness to near-maximum bullishness in a single week is notable and coincides with the stock's post-launch rally: XRPN is up 42% over the past month. The low PCR suggests options traders have rotated toward calls, not puts, even as the share price dipped this week.

The ownership picture explains some of the borrow tightness immediately. Arrington Capital holds 61% of the company, as reported on October 9. SBI Holdings holds a further 15%. Together, those two anchors account for more than three-quarters of outstanding shares, leaving a very thin tradeable float for anyone trying to source stock to short. Two Schedule 13G filings appeared this month: Arrington XRP Capital Fund (a related entity to Arrington Capital) disclosed a 19.9% position filed October 19, and Christian Larsen disclosed 9.9% on October 15. None of these are activist 13D filers, but the concentration of disclosed long holders effectively explains why borrow availability has been near zero. As always with 13D/G disclosures, these stakes reflect positions as last disclosed around the 5% threshold, and holders dropping below that level have no obligation to file again.

ORTEX puts an 83% probability on XRPN being added to the S&P Completion Index and the S&P TMI at the December 2026 Quarterly Review. The rank date is November 16, with an announcement expected December 4 and a trade date of December 18. The projected flows are modest at $16 million for S&P Completion and $8 million for the TMI, representing roughly 0.7 and 0.3 days of normal volume respectively. Given the concentrated float, even modest mechanical buying from index trackers could amplify moves around those dates if the forecast materialises.

The next focal point is the November 16 rank date, which will determine whether XRPN is formally in the frame for the December review. With borrow costs still above 500% and availability prone to collapsing toward zero on active trading days, any further narrowing of the float, or acceleration of index-tracking demand, makes the cost-to-borrow dynamic the key variable to watch rather than the index probability itself.
