TLDR

• Citi reiterated a Buy rating on MongoDB and raised its price target to $450 from $400
• MDB stock gained over 2% in premarket trading on Tuesday
• Citi opened a 90-day positive catalyst watch on the stock
• Channel checks suggest Atlas usage is already ramping at several AI customers in Q1
• Citi models 30% Atlas growth for Q1 and full fiscal year 2027, well above guidance

MongoDB (MDB) stock rose more than 2% in premarket trading on Tuesday after Citi raised its price target to $450, up from $400, while keeping a Buy rating on the stock.

MongoDB, Inc., MDB

The bank also opened a 90-day positive catalyst watch on MDB, signaling it expects near-term developments that could move the stock.

MDB has had a rough 2025, falling around 30% this year. The drop followed a weak outlook issued in March, when the company forecast Q1 profit below expectations and flagged slower growth for Atlas, its cloud-hosted database.

Citi’s updated view cuts against that bearish narrative.

The bank ran proprietary channel checks with MongoDB customers and partners. What they found: Atlas usage is already picking up at several prominent AI customers, and that ramp is happening in the current quarter.

Atlas Growth Could Top 30%

Based on those checks, Citi built an updated AI customer model. The analysts estimate that AI momentum could lift Q1 Atlas growth by roughly two percentage points versus Q4, pushing it above 30%.

They project Atlas growth could climb further by year-end.

Citi now models 30% Atlas growth for both Q1 and the full fiscal year 2027, which sits well above consensus and the company’s own guidance.

The core thesis from Citi is that MongoDB is holding up better than most software names right now. While broader software budgets have tightened, MongoDB is pulling in new workloads tied to AI development.

The bank’s note specifically calls out “vibe-coded” applications — software built quickly using AI coding tools — as a new source of demand. These projects tend to require write-heavy, schema-evolving databases, which plays to MongoDB’s strengths.

Where MDB Stands Now

The stock was trading around $301 in premarket Tuesday, up roughly $6.67 on the session. It had been sitting near $294 ahead of the note.

MongoDB carries a market cap of approximately $23.68 billion. Its price-to-sales ratio stands at 9.77, and revenue has grown 17.5% over the past three years.

GF Score rates the company 84 out of 100, with a 10/10 on growth and 8/10 on financial strength, though profitability remains a weak spot at just 3 out of 10.

On the insider front, executives sold around $13.2 million worth of stock over the past three months, with no buying reported in that period.
