I present to the $OPEN army, our new anthem.

join us for episode 2 of our monthly $open space series! 🎙️ this month, @jeffye888 is joining us to share his views on the macro environment and how resilient opendoor may be. open army appreciates jeff taking the time to join us and share his perspective. if you don’t know jeff yet, here’s a little more about him nitter.net/i/spaces/1mxPaZNWgqEKN nitter.net/jeffye888/status/19488…

🚨 $OPEN — POSSIBLE ALGORITHMIC MARKET MANIPULATION. @nejatian — I am addressing this directly to you as CEO of Opendoor. After weeks of forensic work on $OPEN trading, I believe our findings justify review by Opendoor, Nasdaq, FINRA and potentially the SEC. As an $OPEN shareholder, I can provide the complete dataset, order IDs, timestamps, code and methodology. We reconstructed ~2.23 MILLION individual orders across Nasdaq, NYSE Arca, Cboe BZX, EDGX and MEMX, covering ~86% of observed volume: MBO/L3 orders, executions, cancellations, off-exchange trades, auctions, options and short-sale data. Thousands of quantitative tests: regressions, event studies, cross-venue synchronization, market-impact models, VPIN and order-lifecycle reconstruction. The findings raise serious questions about potential algorithmic market manipulation. From Sep 9–17 alone, 14:00–15:00 ET produced −4.94M shares of aggressive net flow, negative in 6/7 sessions. But the key evidence is inside the book. 📍 SEP 9 — 11,200 An 11,200-share SELL executes @ $3.05. Then 335 SELL orders of exactly 11,200 shares appear. 326/335 — 97.3% — disappear within ONE SECOND. After $OPEN trades lower: 🟢 BUY 11,200 @ $3.00 → EXECUTED. SELL → REPEATED SUPPLY → CANCEL → LOWER PRICE → BUY If CAT links these actions to the same beneficial owner/coordinated accounts, regulators can determine whether displayed supply influenced price discovery before a lower execution. 📍 SEP 17 — THE $2.57 WALL 172 SELL orders of exactly 14,500 shares. 167/172 — 97.1% — cancelled within one second. Around 108 identical 14,500-share SELL orders repeatedly appear around $2.57 while genuine selling hits $OPEN. Median lifetime: ~78 MILLISECONDS. Same size. Same price. Appear. Disappear. Repeat. Genuine liquidity — or the appearance of a larger sell wall than actually intended for execution? 📍 SEP 24 — THE CLOSE Nasdaq SELL imbalance jumps: 354K → 970K → 1.17M shares in ~20 seconds. At virtually the same time, selling appears across ALL FIVE exchanges. Around 15:54:40 ET, in ~ONE SECOND: 🔴 ~134,060 aggressively SOLD 🟢 ~810 aggressively BOUGHT ~165 : 1 Nasdaq. Arca. EDGX. BZX. MEMX. The five venues finish at approximately −822K shares of identified aggressive net flow. ⸻ THESE ARE ONLY EXAMPLES. Across the five-exchange sample: 🔴 38,076 large fleeting SELL orders 🔴 ~353M shares of cumulatively displayed sell liquidity A stricter test — 5,000+ share orders appearing before an opposite-side execution and cancelled within 50ms — identified: 68,524 SELL-side candidate sequences vs 49,769 BUY-side = 18,755 more SELL occurrences. We also tested thresholds down to 5 milliseconds. These totals alone don’t prove manipulation; high-frequency activity exists on both sides. But the specific fingerprints come from tens of thousands of order/cancellation sequences and deserve account-level investigation. WE DOCUMENTED: • persistent aggressive selling • identical non-round SELL orders • 97%+ cancellation rates in specific fingerprints • lifetimes measured in milliseconds • apparent sell walls • auction imbalances • simultaneous cross-exchange selling These patterns overlap with spoofing/layering when non-bona-fide liquidity creates misleading supply/demand while genuine transactions obtain an economic advantage. The decisive question: WHO controlled these orders? Public data cannot answer it. The Consolidated Audit Trail (CAT) can. @nejatian , I hope you and @Opendoor take this seriously. I can provide the entire analysis and dataset immediately. If Opendoor does not act, on Monday, as an @Opendoor shareholder, I intend through legal counsel to submit the prepared documentation directly to the SEC and appropriate regulators for independent review and to protect Opendoor shareholders’ interests. The data, order IDs, timestamps and anomalies exist. Now they deserve to be investigated. @rabois @ericjackson @mikealfred

Got some feedback that I should share more about my background at @Opendoor Over 3 years (2016 - 2019) was lucky enough to touch... - Pricing experimentation w/ @LeoPekelis, @sri_batchu, and Nelson Ray - Portfolio and risk management w/ @dsinsky and @cal_arora - Built the core financial and operating model (from scratch!) w/ @btulsiani2, @jechild, @pan_yvette, Rajiv Krishnarao - Worked with Market GM's on planning and goal setting w/ Megan Meyer Toolson and Chris O'Riordan I think we all knew back then that there was something special about what we were building. The caliber of the team was absolutely INSANE. I only have the best intentions at heart for the company and I know there's still some of that magic left. Let's try to recapture it💖 $OPEN

We’re in the business of making the American dream more accessible to every day folks, not email. Software that directly lies on that pathway, that only Opendoor can build, we will build, otherwise it’s a distraction

that’s fair. i know one of them was sold. going to check the other ones sometime today. and keep in mind: lennar core competency is building homes not selling homes. the idea is for them to focus on what they do best and what they need to get faster. not there yet.
