Most runners know a training partner who undersells the pace. They promise an easy jog, then leave you gasping by mile two. Soon you ignore the promise and watch the stopwatch.
MongoDB Inc. (MDB) investors face the same problem with management’s historically cautious guidance. Heading into the company’s investor day in New York on Tuesday, Sept. 29, 2026, Wall Street is ready to ignore the promises and just watch the stopwatch.
The company’s official plan calls for revenue growth in the high teens, according to its 2025 investor day presentation. Yet revenue grew 30% last quarter, its fastest pace in several years, MongoDB said in its second-quarter earnings release.
That growth target is the number to watch. Bank of America reiterated its Buy rating. If management lifts the target, analysts led by Koji Ikeda think the stock could earn a richer valuation.
If nothing meaningful changes, the event is unlikely to move the shares, they wrote in a Sunday, Sept. 20, 2026, note shared with TheStreet.
MongoDB has already outgrown its own plan
That plan also targets adjusted operating margins above 20% within three to five years, the presentation shows. It calls for more than 20% growth from Atlas, the cloud database behind about 73% of second quarter revenue, according to the earnings release.
Those goals look dated. MongoDB now guides for fiscal 2027 revenue growth of 21% to 23% and an adjusted operating margin near 21%, CFO Mike Berry said on the earnings call. The company is set to clear its margin goal in the first full year of the plan.
Berry told analysts MongoDB will “always be prudent” when guiding beyond the next quarter.
That caution has cost shareholders before. Shares fell 3.7% after the current framework debuted, Benzinga reported. They dropped more than 20% in March 2026 after a cautious annual outlook.

What MongoDB stock is pricing in right now
MongoDB sells the database software behind live apps, from bank payments to AI chatbots.
Customers rent it as the Atlas cloud service or run it themselves as Enterprise Advanced, according to StockAnalysis. That makes the stock a direct test of whether AI apps become real database spending.

Shares traded near $398 on the afternoon of Monday, Sept. 21, 2026, up about 4%, and closed at $407.30. That leaves them roughly 14% below the 52-week high of $473.10, StockAnalysis data shows.
Investors have been tough on good news. The stock fell 13.5% on Wednesday, Sept. 2, 2026, even though revenue and profit beat estimates. The culprit was Atlas, which grew near 29% for a fifth straight quarter, Berry noted on the call.
Investors wanted acceleration, not consistency.
Analysts already model about 20% average annual revenue growth over three years, according to consensus estimates compiled by StockAnalysis. That sits above MongoDB’s own target.
A reset to that level would confirm the Street’s math rather than beat it. Reaffirming the old target could read as a step backward.
According to the note, Bank of America’s $540 price target implies about 40% upside. The bank noted MongoDB trades at 8.6 times estimated 2027 revenue, a steep discount to the 15.2 times average for Datadog (DDOG), Snowflake (SNOW), and JFrog (FROG).
The wider Street is more cautious, with an average target of $456.88 across 41 analysts, according to StockAnalysis.
Coding agents are sending MongoDB new customers
New demand has an unexpected source. CEO CJ Desai told analysts most referral traffic for Voyage AI, MongoDB’s tools that help AI apps search by meaning, comes through coding agents.
Anthropic’s Claude sends the most, followed by OpenAI’s Codex, he said. Many Voyage newcomers had never worked with MongoDB, Desai added.
That flips a popular fear. The same kind of AI agent that rattled software stocks this year now feeds MongoDB’s sales funnel.
In its note, Bank of America calls hard AI usage data the clearest upside trigger next week.
Other signals to watch:
- Enterprise Advanced’s annual recurring revenue grew about 11% last quarter, a third straight double-digit gain, Berry said. Bank of America calls it a second growth engine.
- Voyage AI’s customer count roughly doubled in each of the last two quarters, the company said. That widens the pool of future Atlas buyers.
- A new hosted MCP server lets coding agents tap live Atlas data directly, according to the earnings release. Bank of America says it could put MongoDB where new apps begin.
Software’s real fight is over the long run
During February’s AI sell-off, JPMorgan analyst Toby Ogg said investor worries centered on growth beyond standard three-year forecasts, Reuters noted. That is why multiyear targets now matter more than strong quarters.
Not everyone buys the bull case. Artisan Partners trimmed MongoDB in its Mid Cap Fund, warning in a second-quarter letter that AI could lower switching costs and squeeze database pricing, according to Insider Monkey.
Next week’s answer will matter beyond one database company. It will test whether software companies can prove that AI agents are customers, not competitors.
