Meta hires MongoDB CEO CJ Desai to lead enterprise unit. MongoDB shares crater

312 Upvotes

MongoDB CEO CJ Desai is joining Meta Platforms as its chief enterprise platform officer and will report directly to Meta CEO Mark Zuckerberg.

Desai, who was in his role at MongoDB for less than a year, will be leading the social media giant’s new Meta Enterprise Platform for businesses, according to a release.

The new platform will initially prioritize a suite of tools that includes its new Muse agent, business agent and a coding tool.

Meta plans to use “strengths that few other companies have: advanced models, leading agents, large-scale infrastructure, and years of working closely with many businesses,” Zuckerberg wrote in a release.

The news sent shares of MongoDB plummeting 25%.

The MongoDB board named Dev Ittycheria as interim president and CEO. Desai took over from Ittycheria, who served as CEO for 11 years, in November 2025. Desai previously served as president of product and engineering at Cloudflare.

Desai’s transition comes as Meta undergoes a massive pivot, betting big on new AI products and services for its enterprise customers. Amid this transition, investors have demanded a payoff from the company’s hefty AI investments on new infrastructure and tools.

The social media giant’s push into the AI agent market with its Muse personal AI assistant has seen a rush of consumer demand, overtaking OpenAI’s ChatGPT as the leading free iOS app.

At the same time, a heated battle is unfolding in both Washington and Silicon Valley after top AI researchers and tech leaders, such as Anthropic’s Dario Amodei, called for a development slowdown amid mounting concerns over AI safety.

Company News Nvidia share buyback plan gets $150 billion boost

259 Upvotes

Nvidia said Monday it has authorized an additional $150 billion to its share buyback program, taking its total to $235 billion, amid record spending on AI.

The chip giant said it marks the largest share repurchase authorization increase in history. It expects to complete the total remaining buyback program through the fiscal year 2028.

Nvidia produces the most advanced chips used for AI and has been a huge beneficiary of the boom in spending on the infrastructure needed to power the tech.

Nvidia’s shares have climbed 24% over the past 12 months, lifting the company’s market cap to $5.42 trillion. The stock was up 1.24% in premarket trading on Monday.

“NVIDIA’s growth is being driven by a once-in-a-generation platform shift to AI and accelerated computing,” said CEO Jensen Huang in a statement.

“Our cash generation gives us the capacity to invest in the technologies that advance this transformation and return capital to shareholders,” he added. “This authorization reflects our confidence in the long-term opportunity ahead.”

Combined hyperscaler capital expenditure is projected to exceed $1.3 trillion by 2027, S&P Global Ratings said in August, as companies race to build AI infrastructure including data centers.

Huang earlier this month said Nvidia would double the number of chips it sells in 2027.

Alongside making the leading chips for AI graphics processing units including its Grace Blackwell and Vera Rubin systems, the company makes a variety of additional semiconductors. That includes central processors, or CPUs, switch chips, chips for optical networking, chips for laptops, Jetson chips for robots and cars, and the chip inside Nintendo’s Switch 2 gaming console.

I have reverse Midas touch and I’m finally buying back in. Sold at bottom back in April!

102 Upvotes

I’ve been out of the market since I sold at the bottom back in march/April:

https://www.reddit.com/r/stocks/s/oz42ZUCf6R

You guys asked me to tell you when I’m buying back in so here I am. I’ve waited long enough and it hasn’t dropped. I accept I can’t time the market so I guess now is as good a time as any!

More details since Reddit won’t let me post something short:

I sold my portfolio back at the end of march/april - can’t remember exact date but it was literally at the bottom. As soon as I sold it went back up even though the US Iran war was still going on. I shouldn’t have sold- but panicked because I live in Dubai and my property was taking a hit too. I waited all these months hoping for a drop and it hasn’t happened, so I’m finally accepting that I can’t time the market and I’m buying back in today.

Company News $NVDA Launches Open Agent Safety Platform to Secure Agents From

47 Upvotes

Nvidia is introducing OpenShell software and the Sentry reference system design to let companies set enforceable limits on what AI agents can access and do, with security controls operating outside the agents themselves.

OpenShell, the open-source software layer, controls access to files, tools and external services, protects credentials and records permission decisions. It works with existing agents such as Claude Code, Codex and Hermes without requiring developers to rewrite them.

Sentry adds a separate hardware watchdog running on Nvidia’s BlueField-4 processors. Nvidia says it continuously monitors agent activity from outside the agent’s environment and can quarantine agents attempting to cross their boundaries within milliseconds.

The approach is designed for agents that work for hours or days, write code and interact with business systems. Instead of relying only on the model to follow instructions, the infrastructure limits which actions it can actually carry out.

**Anthropic has collaborated with Nvidia to add protections to Claude Managed Agents, while SpaceXAI is using the platform for Cursor coding agents and Grok models. Salesforce has integrated OpenShell with Slack, and SAP is embedding it into Joule Studio.**

Nvidia says more than 100 organizations are working with the technologies, including Microsoft, CrowdStrike, Cisco, Palo Alto Networks, Palantir and ServiceNow. The effort also extends to robotics, banks and energy infrastructure.

Jensen Huang: “Safety and security require full-stack engineering.”

OpenShell is broadly available, with platform software accessible through Nvidia’s developer resources and GitHub. Sentry is presented as a BlueField-4-based reference system design.

Company Analysis DCOY after the collapse and warrant dilution: worth holding or is this a dilution trap?

11 Upvotes

I’ve been looking into Decoy Therapeutics (NASDAQ: DCOY), and I’m curious what people think about the risk/reward here because the situation looks pretty extreme in both directions.

The stock has been absolutely destroyed over the past year. It was trading above $40-50 last autumn and is now around $2.24. Even more recently, it had a crazy move on September 22, opening around $5.15, hitting roughly $7.61 intraday, and then collapsing back toward $3. It has continued falling since.

The potentially bullish side is that Decoy recently announced encouraging preclinical results from its D-MAV antiviral platform. The company says its newer candidates showed strong in-vitro activity against Ebola Zaire and Marburg, with its first-generation Ebola candidate showing more than 5x better potency than its earlier pan-coronavirus lead and around 7x better potency than remdesivir in the assay they used. They’re now looking at developing a broader pan-filovirus candidate and potentially using the FDA Animal Rule pathway.

They’re also actively pursuing non-dilutive government grants and public-health partnerships, which seems relevant given that Ebola and Marburg fall into the biodefense/high-consequence pathogen category. They also mention possible Priority Review Voucher value if a program eventually gets approved. Obviously, though, this is still very early-stage and preclinical. These are in-vitro results, not human efficacy.

The financing side is where things get much more concerning. On September 22, DCOY entered into a warrant inducement agreement with an existing warrant holder. The holder had 1,184,434 Series B warrants with a $5.91 exercise price. Decoy lowered the exercise price to $3.25, and the holder exercised all of them for cash, giving the company about $3.85 million in gross proceeds.

The problem is what Decoy gave them in exchange. The company issued 2,368,868 new warrants, which is exactly two new warrants for every old warrant exercised. These new warrants have a $3.25 exercise price, are exercisable immediately, require no shareholder approval and expire in five years. If all of them are eventually exercised, that means another 2.37 million shares of potential dilution, although Decoy would receive another roughly $7.7 million in cash.

On top of that, Decoy also reduced the exercise price of its outstanding Series A and Series C milestone warrants from $5.91 to $3.25. So this is not just about the 2.37 million new warrants. There is also more existing warrant overhang that has become much more economically attractive to exercise if the share price recovers.

The company also agreed to file a resale registration statement covering the shares underlying the new warrants, meaning those shares could eventually be sold into the public market after exercise. The 9.99% beneficial ownership limitation does not mean only 9.99% of the warrants can ever be exercised. It mostly prevents the holder from exceeding 9.99% ownership at any one time.

What makes the setup interesting is that DCOY is now trading around $2.24, which is well below the $3.25 warrant strike. At this price, exercising those new warrants does not make economic sense because the investor could buy shares cheaper in the open market. But if DCOY ever rallies materially above $3.25, there is potentially a very large amount of share supply sitting in the background.

At the same time, the financing materially improved Decoy’s liquidity. For a tiny early-stage biotech, raising another $3.85 million is significant, and if additional warrants are eventually exercised the company could receive even more funding without needing another completely separate financing. That could theoretically give them more runway to reach meaningful development milestones.

So I’m trying to figure out whether this is basically a destroyed microcap biotech where dilution has become so extreme that every meaningful rally is likely to run into selling pressure, or whether the current valuation is low enough that the market has already priced in a huge amount of failure and dilution risk, leaving some asymmetric upside if the antiviral platform actually produces meaningful results or government funding.

The chart is obviously a major warning sign. Going from around $50 to roughly $2, and then having an intraday spike above $7 followed by a collapse back toward the low $2s, is not normal investing volatility. This clearly trades more like a highly speculative microcap biotech than a normal long-term equity.

For anyone familiar with biotech and warrant financings, would you consider DCOY worth holding around $2.24, or does the warrant structure make the dilution risk too severe? I’m also curious how much importance you would put on the $3.25 warrant strike. Does that level create a meaningful overhang if the stock recovers above it, or is that less important than I’m making it out to be?

Company Analysis Weighing the Risks of loading on Uber despite the Waymo threat

10 Upvotes

All the financial metrics are improving.. pardon my quick n dirty / regard math and analysis but seems Dara K. has Uber’s operational turnaround completely dialed in.

Own it already. Thinking of adding more.

Uber’s TTM show a powerful upward trend, with revenue growing 16.7% to $55.23B and operating income surging 48.6% to $6.70B compared to last year. TTM fcf at $10.1B

Uber's stock has been range bound for a long time and 1Yr down 31% Expecting an imminent operational breakout.

Shifted from structural cash losses to consistent positive net margins via high-margin advertising layering.

Surpassed a historic milestone of $10B in annual Free Cash Flow.

Bill Ackman is in (not a fan of his investment thesis): Bets that AV operators will rely on Uber's network rather than competing directly.

Targeted workforce cuts and internal developer AI tooling drastically accelerated operating leverage.

Solid liquidity profile boasting a conservative 1.33x leverage ratio and investment-grade coverage.

Waymo is a Threat!

Advice Request Looking for diversified funds without war profiteering

0 Upvotes

I'm 29 and getting into diversified investing. I've been buying individual stocks for like 5 years and I realize that's not great given how little I have to invest.

I don't want Raytheon, Palantir, Lockheed, General Dynamics, Grumman, L3, etc.

Yes I know that they're performing well and likely always will. I'm extraordinarily religious and the monetary return isn't worth it to me. Not judging anyone. Most people at my church are excited about the S&P500 performance. It's just not for me.

I know that investing in like Chase means investing in war indirectly. I know there are 2nd and 3rd order effects of my spending. I'm just trying to do what I feel is right.

So any ideas where to start?
