Archer Aviation Inc (NYSE: ACHR) rallied more than 10% on market open today on speculation that the air taxi firm could soon announce a partnership with Tesla Inc (NASDAQ: TSLA).
The buzz started after ACHR posted a promotion video featuring its Midnight electric vertical take off and landing (eVTOL) aircraft alongside TSLA’s electric vehicle and its Optimus robot.
Retail traders interpreted the imagery as a signal of a forthcoming collaboration, possibly involving autonomous ride-sharing or drone logistics.
Such a partnership could accelerate commercialisation and lend credibility to ACHR’s futuristic vision.
However, caution is still warranted in owning Archer Aviation stock at current levels.
Lack of revenue remains an overhang for Archer Aviation stock
While Archer Aviation continues to secure strategic partnerships, ACHR stock remains a risky bet given that the company has yet to generate any revenue.
Archer Aviation currently boasts a robust cash position – with about $1.72 billion on the balance sheet as of June 2025 – but its burn rate currently sits at north of $200 million per quarter.
This means the company may be reliant on fundraising to sustain operations, which typically leads to shareholder dilution and is, therefore, broadly seen as a major red flag.
As one investor recently noted on Stocktwits, “Cool tech, but until they start selling rides, it’s just a science project.”
In short, without revenue, Archer Aviation shares’ valuation remains speculative and vulnerable to sentiment shifts.
Uncertainty around regulatory certification and commercial scaling
Investors should practice caution in owning ACHR shares, especially after a 100% rally since early April, also because the path to FAA certification remains complex and time-consuming.
Archer Aviation’s aircraft has achieved impressive test milestones, including flights reaching 10K feet and speeds over 120 mph.
Plus, the company is participating in the Trump administration’s eVTOL Integration Pilot Program (eIPP) as well.
But full regulatory approval for passenger operations is still pending.
Moreover, scaling production – especially for urban deployment – requires coordination with local governments, infrastructure upgrades, and public acceptance.
“We’re working closely with the FAA and DOT,” Archer’s chief executive, Adam Goldstein, said in September, “but safety and compliance are non-negotiable.”
All in all, execution risk looms large, and any delays could derail the timeline and investor confidence in Archer Aviation stock.
ACHR shares are in a fiercely competitive market
Another major risk tied to owning ACHR stock is that it’s not alone in the race to dominate urban air mobility.
Rivals like Joby, Lilium, and Vertical Aerospace are also vying for FAA certification and global partnerships.
Joby Aviation, for instance, has already flown passengers under FAA experimental approval and secured deals with Delta and the US military.
Meanwhile, legacy aerospace firms and automakers are entering the fray, bringing deep pockets and manufacturing scale.
Tesla’s rumoured involvement could help Archer Aviation stand out, but it may also attract scrutiny and competitive retaliation.
Put these red flags together with Archer Aviation’s stretched valuation of about 5 times book value, and that stock starts to appear more speculative than transformative.
ACHR’s long-term success hinges not just on innovation, but on execution, differentiation, and timing.
