Taco Bell is apparently teaming up with duolingo...on A sauce. There are mascots that brands try to embed into your everyday lives - and then there's the Duolingo owl. Arguably the pushiest of them all, anyone who's ever downloaded Duolingo, taken four language lessons, and then promptly lost their streak while they got on with something else in their life will be well-acquainted with this little green bird. And not necessarily in a good way. Shaming, passive-aggression, emotional manipulation: These are just a few of the tactics customers feel the company uses to get you back into its app, and they're all delivered via a cartoon feathered owl. Strange world Sporked live in, isn't it? It's about to get a bit stranger. The Duolingo owl is now, apparently, finding yet another way to remind you to brush up on your French skills: Via your Taco Bell sauce packets. A collab may be coming, and it might be the strangest one Sporked has heard all year. Taco Bell x Duolingo. A couple of weeks ago, rumblings started appearing online that Taco Bell might be teaming up with Duolingo on a new sauce. Before Sporked get into the why of it all, let's assess the evidence. The first concrete bit of information Sporked could find was on Reddit, where someone who seemed to be an employee posted a picture of a company document displaying key upcoming events. One of them, dated October 6, stated, "Duolingo Sauce Packet Start Sell." Naturally, this prompted a lot of chatter, but things then went a bit quiet for a few weeks, until Instagram accounts @markie_devo and @alwayslivingmas (the former a food influencer, the latter a Taco Bell fan community page) collaborated on a post about the sauce, with more information. Apparently, Taco Bell and Duolingo will be releasing a limited-edition Duo Habanero Sauce. They stated that the sauce will be available with the purchase of either version of Doritos Locos Tacos or a Doritos Cheesy Gordita Crunch. October 6, incidentally, is National Taco Day, and a comment on the post by an apparent Taco Bell employee confirmed the sauce and said that it would be a one-day-only affair. So...essentially, it's habanero sauce in a branded packet. Nothing wild, nothing too out-there - but a bizarre collaboration. But...Why? Your guess is as good as mine. It's hardly unusual for Taco Bell to make a left-field choice to try and get people talking, as it has done here. Duolingo, meanwhile, loves working with brands you wouldn't expect (Scrub Daddy, "Resident Evil", Chess.com, "Squid Game" - take your pick). If you like super-niche collaborations, this one might be for you. If not, I would not be in the least bit surprised.

Sega is collaborating with Netflix to bring a Crazy Taxi film to the streaming service, written by The Naked Gun reboot's comedy writing duo Dan Gregor and Doug Mand.

A £260 million ($350m) settlement between Google and UK app developers has been approved over Google Play commissions. Google has made no admission of liability or wrongdoing under the agreement. Of the settlement, £160m ($216m) will be allocated to eligible developers and £100m ($134.6m) will cover litigation funding, insurance, legal and other costs.

Duolingo CEO Luis von Ahn sold his entire directly-held Class A common stock on 16 September 2026, liquidating 28,292 shares worth $4.3 million. The transaction was executed under a Rule 10b5-1 trading plan, a predetermined selling schedule that helps insiders avoid concerns about trading on non-public information. Despite the sale, von Ahn retains approximately 3.4 million derivative securities, including Class B common stock convertible into Class A shares. The sale involved converting stock options that were immediately sold as Class A shares, a common insider strategy. At the time of the transaction, Duolingo's shares had declined 47% over the previous year. However, the company's second-quarter revenue grew 18% year-over-year to $298.5 million, whilst daily active users increased 23% to 58.7 million, exceeding projections.

The transaction was executed at $149.33 per share through a Rule 10b5-1 trading plan Chen adopted on 14 June. Following the sale, Chen retains 43,769 shares valued at $6.62 million, representing a 0.09% ownership stake. The sale occurred after Duolingo's stock declined 51% over the preceding 12 months. As of 15 September, shares traded at $153.92, giving the language learning platform a market capitalisation of $6.9 billion. Duolingo reported $1.1 billion in trailing 12-month revenue and $410.8 million in net income, generating revenue through subscriptions and in-app purchases.
Duolingo launches attention guarantees for advertisers, powered by Adelaide. Adelaide's AU metric will power guaranteed media quality thresholds across Duolingo's in-app advertising inventory. Duolingo is launching AU guarantees powered by Adelaide, giving advertisers a contractual commitment to a minimum level of media quality across its in-app inventory using AU, Adelaide's omnichannel metric that predicts a placement's likelihood of capturing attention and driving business outcomes. With the launch, Duolingo joins a growing group of publishers using AU guarantees to bring media quality into the buying process. The offering follows a March 2026 audit of Duolingo's online video (OLV) inventory, which used Adelaide AU to assess the quality of its media placements. The audit found that Duolingo's mobile in-app OLV inventory scored 34% above Adelaide's benchmark. Longer-form formats delivered the strongest AU scores, offering additional insight into how ad experience and format can influence an ad placement's ability to capture attention and drive outcomes in in-app environments. Duolingo is using these findings to inform how it structures its ad offerings, including packages that group higher-attention placements and give advertisers clearer visibility into media quality before they buy. Duolingo also plans to incorporate AU reporting into campaign delivery, enabling advertisers to evaluate media quality alongside other campaign performance insights. "People come to Duolingo to learn, which means they are actively listening, thinking, and responding - not passively scrolling," said Andrew Guendjoian, head of sales, Duolingo. "This research gives advertisers independent proof of the quality of that attention, while AU Guarantees make it easier to buy our inventory with confidence. As we grow the business, we're focused on creating advertising that delivers results for brands, fits naturally into the Duolingo experience, and helps keep learning free for millions of people." "Guarantees are the clearest signal a publisher can send about the quality of its inventory," said Marc Guldimann, co-founder & CEO, Adelaide. "In-app environments like Duolingo can offer some of the most engaged experiences on mobile, but advertisers haven't always had a consistent way to compare their quality with the broader market. With access to AU insights and Guaranteed-AU packages, advertisers can make investment decisions based on a predictive measure of media quality and its likelihood to drive results." Adelaide AU is an omnichannel media quality metric that measures a placement's likelihood of capturing attention and driving business outcomes, based on a combination of placement signals, eye-tracking data, and full-funnel outcomes. Adelaide. Adelaide is the leader in attention-based media quality measurement. Our mission is to bring increased transparency and fairness to advertising by supplying the market with a precise, omnichannel media quality metric connected to business outco... Powered by PressBox
