An AI-Driven Cybersecurity Earthquake Overshadowed an Even Wilder Micro-Cap Session
The S&P 500 closed up 0.72% Thursday as tech and software stocks rallied hard behind twin cybersecurity earnings beats, but the real fireworks happened much further down the market-cap ladder — a placental-cell biotech more than doubled, a reverse-split pharma name surged past 100%, and a diagnostics penny stock jumped 70% on a single peer-reviewed study. Here are the top gaining stocks today, ranked by percentage move.
1. Celularity Inc. (CELU) — Exploded 137.36% to Close at $2.09
Fundamental Data:
| Metric | Value |
|---|---|
| Today’s Close | $2.09 |
| Today’s Move | +137.36% |
| Business | Placental-derived allogeneic cell therapy developer |
| Recent Product News | Cenplacel-L investigational therapy availability with Fountain Life |
| Overhang | Nasdaq listing non-compliance notice (received Aug 21, disclosed Aug 25) |
What Happened: Celularity, a micro-cap biotech developing placental-derived cell therapies, drew a cluster of company-specific catalysts that gave traders a fresh reason for a turnaround trade — announcing the availability of cenplacel-L, its investigational allogeneic cell therapy, for use by licensed physicians in a new state, even while simultaneously disclosing a Nasdaq listing compliance notice received August 21. The combination of expanding clinical access alongside listing uncertainty created unusually high volatility.
What to Watch Tomorrow: With the stock more than doubling in a single session on a mix of genuinely positive commercial news and a looming compliance deadline, watch for Celularity’s formal compliance plan submission to Nasdaq — any credible remediation timeline could sustain today’s momentum, while continued silence on the notice could quickly reverse the rally.
2. Propanc Biopharma (PPCB) — Surged 102.80% to $2.17 Post-Reverse-Split
Fundamental Data:
| Metric | Value |
|---|---|
| Today’s Close | $2.17 |
| Today’s Move | +102.80% |
| Today’s Range | $1.21 – $4.44 |
| Market Cap | ~$7.71 million |
| Today’s Volume | 96.28 million shares (vs. 28,470 average) |
| 52-Week Range | $0.95 – $85.50 |
| Catalyst | New preclinical data for lead drug PRP in pancreatic cancer, published just days after a reverse split |
What Happened: Propanc Biopharma rocketed more than 200% intraday just days after implementing a reverse share split, driven by newly published preclinical data showing its lead proenzyme therapy PRP achieved greater than 90% tumor growth inhibition in pancreatic ductal adenocarcinoma models. Trading volume exploded to more than 3,000 times the stock’s average daily volume.
What to Watch Tomorrow: A trading volume spike this extreme on a microscopic $7.71 million market cap is a textbook low-float squeeze setup — watch for whether the stock can hold anywhere near today’s $2.17 close, since reverse-split names with this kind of volume surge often give back the majority of their gains within one to two sessions once initial momentum fades.
3. VolitionRx Limited (VNRX) — Jumped 70.67% to $0.58 on Sepsis Biomarker Data
Fundamental Data:
| Metric | Value |
|---|---|
| Today’s Close | $0.58 |
| Today’s Move | +70.67% |
| Premarket Move | +97.5% to +100.47% |
| H1 2026 Revenue | $1.4 million (+112% YoY) |
| Total Addressable Market Cited | $26+ billion across all verticals |
| Sepsis TAM | $2.8 billion |
What Happened: VolitionRx surged after a peer-reviewed study in Critical Care Medicine validated its Nu.Q NETs H3.1 biomarker as an independent predictor of 28-day mortality and renal replacement therapy need in sepsis patients — a genuine clinical validation event rather than pure speculation. The company also reported 112% year-over-year revenue growth to $1.4 million and disclosed active discussions with more than a dozen major liquid biopsy and diagnostic firms.
What to Watch Tomorrow: The rally added roughly $4.5 million in equity value against $5.2 million in quarterly operating cash burn — meaningful for a microcap, but small next to the funding needed for full commercialization. Watch for whether any of VolitionRx’s disclosed licensing discussions convert into an actual signed partnership, which would be the next major catalyst beyond today’s validation study.
4. Okta Inc. (OKTA) — Soared 27.61% to $172.91 on an AI-Agent Security Beat
Fundamental Data:
| Metric | Value |
|---|---|
| Prior Close (Aug 26) | $134.42 |
| Today’s Close | $172.91 |
| Today’s Move | +27.61% to +28.87% |
| Fiscal Q2 FY2027 EPS | $1.05 (vs. $0.96 estimate) |
| Fiscal Q2 FY2027 Revenue | $805 million (+11% YoY, vs. $792.1M estimate) |
| Subscription Revenue Growth | +12% to $793 million |
| Remaining Performance Obligations | $4.858 billion (+17% YoY) |
| Billings | $681 million (-5.4% YoY, a bookings softness flag) |
What Happened: Okta delivered a clean beat-and-raise quarter, with management reframing the identity management platform as the essential security layer for AI agents — a narrative that resonated strongly with investors even as billings growth actually declined 5.4% year-over-year, a metric some analysts flagged as worth watching in follow-up notes. Bank of America raised its rating on the stock following the report.
What to Watch Tomorrow: With valuation multiples expanding sharply after this single-day surge, the stock is now exposed to rapid profit-taking if AI-agent security demand growth shows any signs of moderating. Watch the softer billings figure specifically in upcoming analyst commentary — a metric this important showing weakness even during a beat quarter could resurface as a bear case if it doesn’t reaccelerate next quarter.
5. CrowdStrike Holdings (CRWD) — Climbed as Much as 20% on Record ARR Growth
Fundamental Data:
| Metric | Value |
|---|---|
| Today’s Move | +13% to +20.50% (varies by measurement window) |
| Fiscal Q2 Net New ARR | $332.8 million (+51% YoY, above $284-286M guidance) |
| Total ARR (as of July 31) | $5.84 billion (+25% YoY) |
| Falcon Flex ARR Growth | +101% |
| Subscription Revenue | $1.4 billion (+27%) |
| Q3 Revenue Guidance | $1.523B – $1.529B |
| Full-Year Revenue Guidance | $5.991B – $6.011B |
What Happened: CrowdStrike posted its best trading day ever after net new annual recurring revenue blew past guidance by roughly $47-49 million, with CEO George Kurtz framing the results around an AI-driven “arms race” in cybersecurity spending. The company raised its full-year net new ARR growth outlook by 630 basis points.
What to Watch Tomorrow: With Falcon Flex ARR growing 101% and now representing over $2.29 billion of total ARR, watch for continued Falcon Flex adoption rates as the clearest signal of whether today’s guidance raise proves conservative or aggressive relative to actual Q3 performance.
6. Salesforce Inc. (CRM) — Jumped Roughly 14-22% on AI Product Traction
Fundamental Data:
| Metric | Value |
|---|---|
| Today’s Move | +14% to +22.35% (varies by measurement window) |
| Catalyst | Robust AI product traction, expanded Anthropic collaboration |
What Happened: Salesforce shares skyrocketed after the company reported strong momentum in its AI product suite alongside an expanded collaboration with Anthropic, part of a broader session where AI-adjacent enterprise software names across the board posted outsized gains.
What to Watch Tomorrow: With speculation already swirling about a potential Anthropic IPO benefiting Salesforce’s position as a close partner, watch for any additional details on the scope of the expanded collaboration, which could serve as a durable, multi-quarter catalyst beyond today’s single-session pop.
7. BTC Digital Ltd. (BTCT) — Gained 18.23% to $2.14 on a Georgia AI Data Center
Fundamental Data:
| Metric | Value |
|---|---|
| Today’s Close | ~$2.00 – $2.14 |
| Today’s Move | +18.23% |
| Move Since Aug 18 | From under $0.50 to intraday highs above $2.70 (multi-bagger in days) |
| New Facility | 10 MW crypto computing facility in Georgia, ~900 PH/s capacity |
| Revenue | ~$14.04 million |
| Pretax Margin | ~-39.7% |
| Book Value Per Share | ~$3.15 (stock trades below book) |
| Return on Equity | ~-167% |
What Happened: BTC Digital completed a 10-megawatt cryptocurrency computing facility in Georgia, designed to support roughly 900 PH/s of digital asset mining capacity, extending a remarkable run that’s seen the stock multiply more than 4x since August 18. The company also signed a three-party MOU to advance a separate AI data center project in Vietnam this week.
What to Watch Tomorrow: With the stock trading below book value despite deeply negative return on equity, this remains a classic high-beta, low-priced momentum trade rather than a value story — watch the $1.80-$2.25 zone for continued whipsaw action, which has characterized trading since the initial Georgia announcement.
8. Worksport Ltd. (WKSP) — Rose 25.43% to $0.64
Fundamental Data:
| Metric | Value |
|---|---|
| Today’s Close | $0.64 |
| Today’s Move | +25.43% |
| Business | Truck bed covers and solar-integrated accessories |
What Happened: Worksport shares climbed sharply today, continuing the stock’s pattern of sharp, sentiment-driven moves that have characterized its trading throughout 2026 as a smaller-cap name in the solar-integrated automotive accessories space.
What to Watch Tomorrow: Without a single dominant news catalyst identified for today’s specific move, watch for any company announcements in the coming sessions that could explain and potentially extend today’s gain; absent fresh news, some retracement toward prior levels would be a typical pattern for a move of this size.
9. GameStop Warrants (GME.W) — Spiked 44.13% to $2.58
Fundamental Data:
| Metric | Value |
|---|---|
| Today’s Close | $2.58 |
| Today’s Move | +44.13% |
| Instrument Type | Warrants (leveraged exposure to GameStop common stock) |
What Happened: GameStop warrants surged sharply today, with the leveraged instrument amplifying whatever move occurred in GameStop’s underlying common shares — a reminder that warrant price action can swing dramatically more than the underlying stock itself, in either direction.
What to Watch Tomorrow: Given the leveraged nature of warrants, watch GameStop’s common stock (GME) directly for the underlying driver of today’s move; any reversal in the common shares would likely produce an even sharper reversal in the warrant price given the embedded leverage.
10. A Broader AI-Rally Halo Effect
Fundamental Data:
| Metric | Value |
|---|---|
| Nvidia (NVDA) | +7% to +9.32%, on $96.2 billion quarterly revenue (+106% YoY) |
| Cybersecurity ETF (CIBR) | +3%, up 31% year-to-date |
| Palo Alto Networks (PANW) | +5% to +12.83% |
| Broader Sector Move | SailPoint, Zscaler, Rubrik all +10%+ |
What Happened: Beyond the individually-named names above, Nvidia’s blowout quarterly report — $96.2 billion in revenue with data center revenue hitting a record high — provided the macro tailwind lifting nearly the entire AI and cybersecurity software complex simultaneously, creating one of the broadest single-session rallies of 2026 across both mega-cap and small-cap AI-adjacent names.
What to Watch Tomorrow: With so many AI-linked names moving together on the same day, watch for any signs of rotation or profit-taking that could test whether today’s gains represent a durable re-rating of the entire sector or a single-session, earnings-driven spike.

| 9 | GME.W | GameStop Warrants | +44.13% | $2.58 | Leveraged exposure to GME move |
| 10 | — | Broader AI/cyber rally | +5% to +31% YTD (sector) | — | Nvidia’s record quarter halo effect |
Sector Sentiment Snapshot and Forecast
Today’s session tells two parallel stories at once: a legitimate, fundamentals-driven AI infrastructure and cybersecurity rally (Okta, CrowdStrike, Salesforce, Nvidia) built on genuine beat-and-raise quarters, and a completely separate universe of micro-cap biotech and crypto-adjacent names (Celularity, Propanc, VolitionRx, BTC Digital) moving on binary clinical catalysts, reverse-split mechanics, and speculative momentum largely disconnected from the broader market’s AI narrative. The scale of today’s cybersecurity moves — Okta’s steepest single-day gain in years alongside CrowdStrike’s best trading day ever — suggests the market is pricing in a structural, multi-year AI-driven security spending cycle rather than a one-quarter blip. Meanwhile, the micro-cap gainers serve as a reminder that explosive percentage moves in this market are just as likely to come from a $7 million market-cap biotech’s preclinical data as from a well-covered enterprise software giant’s earnings beat.
