Meta Stock: Zuckerberg’s Open-Weight AI Push Faces a 91% Free-Cash-Flow Drop

MENLO PARK, California, August 16, 2026, 19:34 PDT

Meta’s second-quarter free cash flow fell 91% to $784 million.
Revenue rose 28%, while capital spending jumped 83% to $31.08 billion.
Analysts remain mostly positive, but targets fell after the report.

Meta Platforms, Inc. NASDAQ:META enters the new week with a stark AI funding test. Second-quarter free cash flow fell 91% even as revenue climbed 28%.

The gap matters more than another model launch. Meta’s ad engine is growing fast, but almost every dollar of operating cash was absorbed by infrastructure.

Mark Zuckerberg’s latest open-weight push raised the competitive stakes. Meta released the small Muse Glimmer agentic model on August 10 and previewed a stronger Muse Spark 1.2. Glimmer can run on personal devices or a single graphics processor.

U.S. markets were closed Sunday. Meta ended Friday at $589.85, down 0.86% for the session. The shares had gained 2.8% on Thursday as large technology stocks lifted Wall Street.

The core business still has momentum. Ad impressions rose 14%, while the average price per ad increased 12%. Family daily active people reached 3.60 billion, up 3%.

Costs moved much faster. Total expenses increased 55%, including $2.40 billion of legal charges and $1.18 billion of severance expense. Operating margin fell to 31% from 43%.

That leaves the cash conversion as the key investor measure. Operating cash flow reached $31.86 billion. Capital expenditure, including finance-lease principal, reached $31.08 billion.

Free cash flow therefore equaled only 2.5% of capital spending. Its margin was 1.3% of revenue. Those ratios were about 50.3% and 18.0% a year earlier, respectively.

Zuckerberg said AI was “accelerating our core business today.” The ad numbers support that claim. They do not yet prove that frontier models will earn enough outside advertising.

Muse Glimmer sharpens that question. Open weights can broaden adoption and reduce reliance on closed platforms. Yet wide distribution does not automatically create revenue.

Meta has one near-term bridge. UBS said its Business Agents product reached one million business accounts within a month. Charging through subscriptions and token usage is planned for the second half of 2026.

Wall Street still sees upside. However, post-earnings target cuts show that investors want clearer payback before granting Meta its old valuation premium.

Analyst	Rating	Target	Upside to $589.85
Cantor Fitzgerald	Overweight	$680	15.3%
UBS	Buy	$715	21.2%
Goldman Sachs	Buy	$725	22.9%
JPMorgan	Neutral	$640	8.5%
BMO Capital	Market Perform	$720	22.1%
Citizens	Market Outperform	$770	30.5%

Targets were issued July 29-30 after Meta’s second-quarter update.

Meta guided third-quarter revenue to $61 billion to $64 billion. It also narrowed 2026 capital spending to $130 billion to $145 billion, raising the lower bound by $5 billion.

The week ahead starts Monday. Investors will watch Muse distribution, Business Agents pricing and any evidence that open-weight adoption can produce cash returns.

Risks: Ad demand could weaken, AI revenue could arrive later than expected, and spending may remain elevated. Meta also warned that active youth-related legal matters could cause a material loss.

Further analysis

Editorial insight

Why is Meta’s free cash flow currently the primary concern for investors?

Free cash flow for the second quarter declined by 91% to $784 million. Capital expenditures totaled $31.08 billion, using approximately 97.5% of operating cash flow. As a result, only a small portion of cash remained after investments, even with robust revenue growth.

Does Meta’s ad business continue to generate enough revenue to support its AI investment?

The advertising segment continues to perform well. Revenue increased by 28% to $60.80 billion, with ad impressions up 14% and the average price per ad rising 12%. But expenses climbed 55%, pushing the operating margin down to 31% from 43%.

In what ways could Meta generate revenue from its latest AI models aside from advertising?

Muse Glimmer further develops Meta’s open-weight model approach, yet distribution by itself does not guarantee earnings. Business Agents presents a more immediate pathway. The product achieved one million business accounts in its first month, with plans for subscription and token-based billing in the latter half of 2026. Both scale and timing are still unclear.

What is Meta’s projected spending for 2026?

Meta forecasts capital expenditures between $130 billion and $145 billion, having increased the lower end of this projected range by $5 billion. The company also anticipates total costs will reach between $165 billion and $169 billion, with revenue for the third quarter projected at $61 billion to $64 billion.

What are the key risks facing Meta stock?

The main risk is slower returns from AI investments, with spending levels still elevated. Softer advertising demand would cut into the cash available for such investment. Legal and regulatory issues also continue to be significant, such as youth-related cases that Meta warned could result in a major loss.
