Accounting Policies [Abstract]
Description of Business and Basis of Presentation	1. Description of Business and Basis of Presentation Organization Arcadia Biosciences, Inc. (the "Company," "Arcadia" or "management"), was incorporated in Arizona in 2002 and maintains its headquarters in Dallas, Texas, with additional office space in Davis and Sacramento, California, and additional facilities in American Falls, Idaho. The Company was reincorporated in Delaware in March 2015 . The Company is a producer and marketer of innovative, plant-based food and beverage products. Its history as a leader in science-based approaches to developing high-value crop improvements, as well as nutritionally enhanced food ingredients, has laid the foundation for its path forward. The Company used advanced breeding techniques to develop these proprietary innovations which are now being commercialized through the sales of seed and grain, as well as food ingredients and products. The acquisition of the assets of Live Zola, LLC (“Zola”) added coconut water to the Company's portfolio of products. In May 2021, the Company’s wholly owned subsidiary Arcadia Wellness, LLC (“Arcadia Wellness” or “AW”) acquired the businesses of Eko, Lief, and Zola. The acquisition included consumer CBD brands like Soul Spring™, a CBD-infused botanical therapy brand in the natural category, Saavy Naturals™, a line of natural body care products and ProVault™, a CBD-infused sports performance formula made with natural ingredients, providing effective support and recovery for athletes (collectively "body care brands"). Also included in the purchase was Zola, a coconut water sourced exclusively with sustainably grown coconuts from Thailand. In August 2019, the Company entered into a joint venture agreement with Legacy Ventures Hawaii, LLC (“Legacy,” see Note 6) to grow, extract, and sell hemp products. The partnership Archipelago Ventures Hawaii, LLC (“Archipelago”), combines the Company’s extensive genetic expertise and resources with Legacy’s experience in hemp extraction and sales. In October 2021, Arcadia and Legacy mutually agreed to wind down the cultivation activities of Archipelago, due to regulatory challenges and a saturated hemp market. In February 2012, the Company formed Verdeca, which was equally owned with Bioceres. Verdeca was formed to develop and deregulate soybean varieties using both partners’ agricultural technologies. In November 2020, Arcadia sold its membership interest in Verdeca to Bioceres in a transaction in which Arcadia received cash, shares of Bioceres stock and a royalty stream of up to $ 10.0 million on sales of Haab 4 soybeans (“HB4”). An additional $ 2.0 million in cash is to be paid upon achievement by Verdeca of reaching commercial plantings of at least 200,000 hectares of HB4 or China approving the HB4 soybean trait for “food and feed”. During 2022, Bioceres received China's approval of the HB4 soybean trait and as a result, Arcadia recorded license revenue of $ 862,000 and a gain on sale of Verdeca of $ 1.1 million on the condensed consolidated statements of operations and comprehensive loss. The Company received the full payment of $ 2.0 million as of September 30, 2023. Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial statements and are in the form prescribed by the Securities and Exchange Commission (the “SEC”) in instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, the accompanying condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the periods indicated. All material intercompany accounts and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company, Arcadia Wellness, and Archipelago. The Company uses a qualitative approach in assessing the consolidation requirement for variable interest entities ("VIEs"). This approach focuses on determining whether the Company has the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and whether the Company has the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the VIE. For all periods presented, the Company has determined that it is the primary beneficiary of Archipelago, a joint venture, as it has a controlling interest in Archipelago. Accordingly, the Company consolidates Archipelago in the condensed consolidated financial statements after eliminating intercompany transactions. For consolidated joint ventures, the non-controlling partner’s share of the assets, liabilities and operations of the joint venture is included in non-controlling interests as equity of the Company. The non-controlling partner’s interest is generally computed as the joint venture partner’s ownership percentage of Archipelago. Net loss attributable to non-controlling interest of $ 10,000 and $ 152,000 is recorded as an adjustment to net loss to arrive at net loss attributable to common stockholders for the three and nine months ended September 30, 2022, respectively. There was minimal activity during the three and nine months ended September 30, 2023. The non-controlling partner’s equity interests are presented as non-controlling interests on the condensed consolidated balance sheets. The information included in these condensed consolidated financial statements and notes thereto should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations included herein and Management’s Discussion and Analysis of Financial Condition and Results of Operations and the condensed consolidated financial statements and notes thereto for the fiscal year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K, filed with the SEC on March 30, 2023. Reclassifications Certain previously reported financial information has been reclassified to conform to the current year presentation. For a discussion of the reclassification of the financial presentation of our former body care brands reported as discontinued operations, see “Discontinued Operations” section below. Unless otherwise noted, amounts and disclosures throughout these notes to condensed consolidated financial statements relate solely to continuing operations and exclude all discontinued operations. Reverse Stock Split In February 2023, the Company’s board of directors approved a reverse split of 40:1 on the Company’s issued and outstanding common stock. On F ebruary 15, 2023, the Company’s stockholders approved the certificate of amendment, which the Company filed on February 27, 2023 with the Secretary of State of Delaware to effect the reverse split on March 1, 2023. As a result of the reverse stock split, additional shares of common stock of 19,118 were issued in lieu of fractional shares. All issued and outstanding common stock, options to purchase common stock and per share amounts contained in the condensed consolidated financial statements have been retroactively adjusted to reflect the reverse stock split for all periods presented. Liquidity, Capital Resources, and Going Concern The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities during the normal course of business. Since inception, the Company has financed its operations primarily through equity and debt financings. As of September 30, 2023, the Company had an accumulated deficit of $ 269.0 million, cash and cash equivalents of $ 10.6 million and short-term investments of $ 5.1 million. For the nine months ended September 30, 2023, the Company had net losses of $ 11.1 million and net cash used in operations of $ 11.1 million. For the twelve months ended December 31, 2022, the Company had net losses of $ 15.6 million and net cash used in operations of $ 14.0 million. With cash and cash equivalents of $ 10.6 million and short-term investments of $ 5.1 million as of September 30, 2023, the Company believes that its existing cash, cash equivalents and short-term investments will not be sufficient to meet its anticipated cash requirements for at least the next 12-18 months from the issuance date of these financial statements, and thus raises substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. The Company may seek to raise additional funds through debt or equity financings. The Company may also consider entering into additional partner arrangements. The sale of additional equity would result in dilution to the Company’s stockholders. The incurrence of debt would result in debt service obligations, and the instruments governing such debt could provide for additional operating and financing covenants that would restrict operations. If the Company requires additional funds and is unable to secure adequate additional funding at terms agreeable to the Company, the Company may be forced to reduce spending, extend payment terms with suppliers, liquidate assets, or suspend or curtail planned product launches. Any of these actions could materially harm the business, results of operations and financial condition. Discontinued Operations In July 2023, management made the decision to exit its body care brands as a result of continued pressure on the CBD market due to regulatory uncertainty. This decision will streamline the business and allow the Company to focus on growth of the its other “core” brands, which consist of the GoodWheat portfolio and Zola. Body care operations ceased as of September 30, 2023. In accordance with the provisions of ASC 205-20, the Company has separately reported the assets and liabilities of the discontinued operations in the condensed consolidated balance sheets and the results of the discontinued operations as a separate component of income on the condensed consolidated statements of operations and comprehensive loss for all periods presented. Major classes of line items constituting the balance sheet of discontinued operations: (In thousands) September 30, 2023 December 31, 2022 Assets Accounts receivable and other receivables $ 165 $ 66 Inventories, net — current — 250 Prepaid expenses and other current assets — 14 Property and equipment, net — 24 Total assets $ 165 $ 354 Liabilities Accounts payable and accrued expenses $ 31 $ 26 Total liabilities $ 31 $ 26 Major classes of line items constituting net loss from discontinued operations: Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (In thousands) Product revenue $ 37 $ 308 $ 373 $ 2,282 Cost of revenues ( 34 ) ( 214 ) ( 313 ) ( 3,046 ) Impairment of intangible assets — — — ( 72 ) Impairment of property and equipment — ( 24 ) — ( 370 ) Selling, general and administrative ( 86 ) ( 659 ) ( 651 ) ( 2,430 ) Net loss from discontinued operations $ ( 83 ) $ ( 589 ) $ ( 591 ) $ ( 3,636 ) The following table presents significant non-cash items of discontinued operations: Nine Months Ended September 30, (In thousands) 2023 2022 Depreciation $ 24 $ 83 Impairment of intangible assets $ — $ 72 Write-down of inventories $ — $ 806 Impairment of property and equipment $ — $ 370 Accounts receivable and other receivables $ ( 99 ) $ 517 Inventories $ 250 $ ( 247 ) Prepaid expenses and other current assets $ 14 $ 125 Accounts payable and accrued expenses $ 5 $ ( 396 ) There were no other significant operating or investing non-cash items for the nine months ended September 30, 2023 and 2022.

Inventory Disclosure [Abstract]
Inventory	3. Inventory Inventory costs are tracked on a lot-identified basis and are included as cost of revenues when sold. Inventories are stated at the lower of cost or net realizable value. The Company makes adjustments to inventory when conditions indicate that the net realizable value may be less than cost due to physical deterioration, obsolescence, changes in price levels, or other factors. Additional adjustments to inventory are made for excess and slow-moving inventory on hand that is not expected to be sold within a reasonable timeframe to reduce the carrying amount to its estimated net realizable value. The write-downs to inventory are included in cost of revenues and are based upon estimates about future demand from the Company’s customers and distributors and market conditions. The Company recorded inventory write-downs of $ 252,000 and $ 444,000 related to packaging materials, hemp seed and GoodWheat during the three and nine months ended September 30, 2023. The Company recorded write-downs of CBD oil of $ 15,000 during the three months ended September 30, 2022 and of wheat, hemp seed, CBD oil and body care inventories of $ 1.5 million during the nine months ended September 30, 2022. Of inventory write-downs during the nine months ended September 30, 2022, $ 394,000 was related to the Radiance Beauty licensing agreement. If there are significant changes in demand and market conditions, substantial future write-downs of inventory may be required, which would materially increase the Company’s expenses in the period the write down is taken and materially affect the Company’s operating results. Inventories, net consist of the following (in thousands): September 30, 2023 December 31, 2022 Raw materials $ 530 $ 610 Goods in process 133 — Finished goods 3,618 2,478 Inventories $ 4,281 $ 3,088

Investments And Fair Value Instruments [Abstract]
Investments and Fair Value Instruments	5. Investments and Fair Value Instruments Available-for-Sale Investments The Company classified short-term investments as “available-for-sale.” These short-term investments are free of trading restrictions. The investments are carried at fair value, based on quoted market prices or other readily available market information. Unrealized gains and losses are included in accumulated other comprehensive loss, which is reflected as a separate component of stockholder’s equity in the condensed consolidated balance sheets. Gains and losses are recognized when realized in the condensed consolidated statements of operations and comprehensive loss. The following tables summarize the amortized cost and fair value of the investment securities portfolio at September 30, 2023 and December 31, 2022 and the corresponding amounts of unrealized gains and losses recognized in accumulated other comprehensive income: (Dollars in thousands) Amortized Unrealized Unrealized Estimated September 30, 2023 Cash equivalents: Money market funds $ 8,672 $ — $ — $ 8,672 Short-term investments: Treasury bills 5,002 87 — 5,089 Total Assets at Fair Value $ 13,674 $ 87 $ — $ 13,761 (Dollars in thousands) Amortized Unrealized Unrealized Estimated December 31, 2022 Cash equivalents: Money market funds $ 18,620 $ — $ — $ 18,620 Total Assets at Fair Value $ 18,620 $ — $ — $ 18,620 The Company did no t have any investment categories that were in a continuous unrealized loss position for more than twelve months as of September 30, 2023. Fair Value Measurement The fair value of the investment securities at September 30, 2023 were as follows: Fair Value Measurements at September 30, 2023 (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets at Fair Value Cash equivalents: Money market funds $ 8,672 $ — $ — $ 8,672 Short-term investments: Treasury bills 5,089 — — 5,089 Total Assets at Fair Value $ 13,761 $ — $ — $ 13,761 The fair value of the investment securities at December 31, 2022 were as follows: Fair Value Measurements at December 31, 2022 (Dollars in thousands) Level 1 Level 2 Level 3 Total Assets at Fair Value Cash equivalents: Money market funds $ 18,620 $ — $ — $ 18,620 Total Assets at Fair Value $ 18,620 $ — $ — $ 18,620 The Company uses the market approach technique to value its financial instruments and there were no changes in valuation techniques during 2023 or 2022. The Company’s financial instruments consist primarily of cash and cash equivalents, short-term investments, accounts receivable and other receivables, accounts payable and accrued liabilities. For short-term investments, accounts receivable and other receivables, accounts payable and accrued liabilities, the carrying amounts of these financial instruments as of September 30, 2023 and December 31, 2022 were considered representative of their fair values due to their short term to maturity or repayment. Cash equivalents are carried at cost, which approximates their fair value. The Company’s Level 3 liabilities consist of a contingent liability resulting from the Anawah, Inc. ("Anawah") acquisition as described in Note 13, as well as preferred investment options related to the March 2023 Private Placement and August 2022 Registered Direct offerings described in Note 9. The contingent liability related to the Anawah acquisition was measured and recorded on a recurring basis as of September 30, 2023 and December 31, 2022, using unobservable inputs, namely the Company’s ability and intent to pursue certain specific products developed using technology acquired in the purchase. A significant deviation in the Company’s ability and/or intent to pursue the technology acquired in the purchase could result in a significantly lower (higher) fair value measurement. The preferred investment option liabilities were measured and recorded on a recurring basis using the Black-Scholes Model with the following assumptions as of September 30, 2023 and December 31, 2022: March 2023 Options - Series A & March 2023 Options - Series B August 2022 Options & August 2022 Placement Agent Options September 30, December 31, September 30, December 31, September 30, December 31, Remaining term (in years) 4.42 — 0.86 — 3.92 4.67 Expected volatility 106.3 % — 89.9 % — 92.2 % 106.2 % Risk-free interest rate 4.7 % — 5.5 % — 4.7 % 4.0 % Expected dividend yield 0 % — 0 % — 0 % 0 % The significant input used in the fair value measurement of the Company’s Level 3 options liabilities is volatility. A significant increase (decrease) in volatility could result in a significantly higher (lower) fair value measurement. The following table sets forth the establishment of the Company’s Level 3 liabilities, as well as a summary of the changes in the fair value and other adjustments (in thousands): (Dollars in thousands) March 2023 March 2023 March 2023 Placement Agent Options August 2022 August 2022 Contingent Total Balance as of December 31, 2022 $ — $ — $ — $ 767 $ 39 $ 2,000 $ 2,806 Initial recognition 4,324 2,274 212 — — — 6,810 Change in fair value and other adjustments ( 2,934 ) ( 2,090 ) ( 146 ) ( 575 ) ( 35 ) — ( 5,780 ) Balance as of September 30, 2023 $ 1,390 $ 184 $ 66 $ 192 $ 4 $ 2,000 $ 3,836 Assets classified as held for sale are recorded at fair value as of September 30, 2023 . The Company has classified the fair value measurements as a Level 3 measurement in the fair value hierarchy as the fair value has been estimated using publicly available prices for some of the assets, and business partners' estimates for assets with prices not readily available, due to the relatively small size of the industry in which they can be used.

Equity Financing	9. Equity Financing March 2023 Private Placement In March 2023, the Company issued in a private placement offering (the “March 2023 Private Placement”) pursuant to a securities purchase agreement (“March 2023 Purchase Agreement”) (i) 165,500 shares of its common stock, (ii) pre-funded common stock purchase warrants (the “March 2023 Pre-Funded Warrants”) to purchase up to 500,834 shares of common stock, at an exercise price of $ 0.0001 per share, (iii) Series A preferred investment options (the “March 2023 Options - Series A") to purchase up to a total of 666,334 shares of common stock, at an exercise price of $ 9.00 per share, and (iv) Series B preferred investment options (the “March 2023 Options - Series B”, and together with the March 2023 Options - Series A, the "March 2023 Options") to purchase up to a total of 666,334 shares of common stock, at an exercise price of $ 9.00 per share, and raised total gross proceeds of $ 6.0 million. The March 2023 Private Placement closed on March 6, 2023. The March 2023 Pre-Funded Warrants became exercisable upon issuance and are exercisable until exercised in full. The March 2023 Options - Series A are exercisable at any time at the option of the holder and expire 5 years from the date of issuance. The March 2023 Options - Series B are exercisable at any time at the option of the holder and expire 1.5 years from the date of issuance. During the nine months ended September 30, 2023, 250,834 Pre-Funded Warrants were exercised. In connection with the March 2023 Private Placement, the Company entered into preferred investment option amendment agreements (the “Option Amendment Agreements”) with certain investors. Under the Option Amendment Agreements, the Company agreed to amend certain existing warrants and preferred investment options to purchase up to a total of 178,132 shares of common stock that were previously issued to the investors in September 2019, May 2020, July 2020, December 2020, January 2021 and August 2022, with exercise prices of $ 300.80 , $ 191.00 , $ 154.00 , $ 120.00 , $ 125.20 and $ 37.35 per share, respectively (the “Existing Warrants”). Under the Option Amendment Agreements, the Company agreed to lower the exercise price of the Existing Warrants to $ 9.00 per share. In addition, the Company granted to a placement agent preferred investment options to purchase a total of 33,317 shares of Common Stock (the “March 2023 Placement Agent Options”) that have an exercise price per share equal to $ 11.25 and a term of 5 years from the date of issuance. The re-pricing of the Existing Warrants resulted in an increase in fair value of $ 404,000 , of which $ 185,000 of the increase in fair value was related to the August 2022 liability classified options. The increase in fair value related to the re-pricing of Existing Warrants was recognized in Valuation Loss on March 2023 PIPE on the condensed consolidated statements of operations and comprehensive loss. The March 2023 Options and March 2023 Placement Agent Options are classified as liabilities within Level 3 due to certain early settlement provisions that preclude them from equity classification. The Company utilized the Black-Scholes Model on March 6, 2023 with the following assumptions for the Series A Investment Options: volatility of 128.55 %, stock price of $ 7.61 and risk-free rate of 4.27 %. The following assumptions were utilized for the Series B Investment Options: volatility of 103.33 %, stock price of $ 7.61 and risk-free rate of 4.97 %. The estimated fair value of the liability classified March 2023 Options issued was $ 6.6 million. The estimated fair value of the common stock option liabilities was subsequently remeasured at September 30, 2023 with the changes recorded on the Company’s condensed consolidated statements of operations and comprehensive loss. The estimated fair value of the common stock issued and March 2023 Pre-Funded Warrants was $ 5.1 million. The total estimated fair value of the common stock issued, March 2023 Pre-Funded Warrants and March 2023 Options as of March 6, 2023 exceeded the gross proceeds of the March 2023 Private Placement by $ 5.7 million and this amount was recognized in Valuation Loss on March 2023 PIPE on the condensed consolidated statements of operations and comprehensive loss. The March 2023 Placement Agent Options were issued for services performed by the placement agent as part of the March 2023 Private Placement and were treated as offering costs. The value of the March 2023 Placement Agent Options was determined to be $ 212,000 , calculated using the Black-Scholes Model. The Company incurred additional offering costs totaling $ 548,000 that consist of direct incremental legal, advisory, accounting and filing fees relating to the March 2023 Private Placement. A total of $ 430,000 was allocated to the common stock option liabilities and expensed while the remaining $ 330,000 was allocated to the common stock and March 2023 Pre-Funded Warrants and offset to additional paid in capital. August 2022 Registered Direct Offering On May 11, 2018, the Company filed a shelf Registration Statement on Form S-3 with the SEC which was declared effective on June 8, 2018 (“2018 Shelf Registration Statement”). On April 21, 2022, the Company filed a shelf Registration Statement on Form S-3 with the SEC which was declared effective on May 12, 2022 (“2022 Shelf Registration Statement”). Each of the 2018 Shelf Registration Statement and the 2022 Shelf Registration Statement allows the Company to sell any combination of common stock, preferred stock, warrants and units consisting of such securities in one or more offerings from time to time having aggregate offering prices of up to $ 50.0 million. The Company ceased being able to use the 2018 Shelf Registration Statement after June 8, 2021, the three-year anniversary of its effective date. The 2022 Shelf Registration Statement may no longer be used after May 12, 2025, the three-year anniversary of its effective date. In August 2022, the Company entered into a securities purchase agreement (the “August 2022 Purchase Agreement”) pursuant to which it sold (i) 61,250 registered shares of its common stock, pursuant to the 2022 Shelf Registration Statement, (ii) pre-funded common stock purchase warrants (the “August 2022 Pre-Funded Warrants”) to purchase up to 56,813 shares of common stock, at an exercise price of $ 0.004 per share, which the August 2022 Pre-Funded Warrants were registered under the 2022 Shelf Registration Statement, and (iii) unregistered preferred investment options (the "August 2022 Options") to purchase up to 118,063 shares of common stock, at an exercise price of $ 37.35 per share, for total gross proceeds of $ 5.0 million (the “August 2022 Registered Direct Offering”). The August 2022 Registered Direct Offering closed on August 16, 2022 . The August 2022 Pre-Funded Warrants became exercisable upon issuance and were fully exercised during the nine months ended September 30, 2023. The August 2022 Options became exercisable upon issuance and expire 5 years after the date of issuance. In connection with the August 2022 Registered Direct Offering, the Company granted to a placement agent preferred investment options ("August 2022 Placement Agent Options") to purchase a total of 5,904 shares of common stock that have an exercise price per share equal to $ 52.80 and a term of five years . The August 2022 Options and August 2022 Placement Agent Options are classified as liabilities within Level 3 due to certain early settlement provisions that preclude them from equity classification. The Company utilized the Black-Scholes Model on August 16, 2022 with the following assumptions: volatility of 128.46 %, stock price of $ 37.60 , risk-free rate of 2.97 % and a term of 5 years . The estimated fair value of the common stock option liabilities was subsequently remeasured at September 30, 2023 with the changes recorded on the Company’s condensed consolidated statements of operations and comprehensive loss. The August 2022 Placement Agent Options were issued for services performed by the placement agent as part of the August 2022 Registered Direct Offering and were treated as offering costs. The value of the August 2022 Placement Agent Options was determined to be $ 191,000 , calculated using the Black-Scholes Model. The Company incurred additional offering costs totaling $ 488,000 that consist of direct incremental legal, advisory, accounting and filing fees relating to the August 2022 Registered Direct Offering. The offering costs, inclusive of the August 2022 Placement Agent Options, totaled $ 679,000 and were allocated to the common stock option liabilities, the common stock and August 2022 Pre-Funded Warrants using their relative fair values. A total of $ 314,000 was allocated to the common stock option liabilities and expensed while the remaining $ 365,000 was allocated to the common stock and August 2022 Pre-Funded Warrants and offset to additional paid in capital.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation and Employee Stock Purchase Program	11. Stock-Based Compensation and Employee Stock Purchase Program Stock Incentive Plans The Company has two equity incentive plans: the 2006 Stock Plan (“2006 Plan”) and the 2015 Omnibus Equity Incentive Plan (“2015 Plan”). In 2006, the Company adopted the 2006 Plan, which provided for the granting of stock options to executives, employees, and other service providers under terms and provisions established by the Board of Directors. The Company granted non-statutory stock options (“NSOs”) under the 2006 Plan until May 2015, when it was terminated as to future awards, although it continues to govern the terms of options that remain outstanding and were issued under the 2006 Plan. The 2015 Plan became effective upon the Company’s IPO in May 2015 and all shares that were reserved, but not issued, under the 2006 Plan were assumed by the 2015 Plan. Upon effectiveness, the 2015 Plan had 3,860 shares of common stock reserved for future issuance, which included 259 that were transferred to and assumed by the 2015 Plan. The 2015 Plan provides for automatic annual increases in shares available for grant. In addition, shares subject to awards under the 2006 Plan that are forfeited or canceled will be added to the 2015 Plan. The 2015 Plan provides for the grant of incentive stock options (“ISOs”), NSOs, restricted stock awards, stock units, stock appreciation rights, and other forms of equity compensation, all of which may be granted to employees, officers, non-employee directors, and consultants. The exercise price for ISOs and NSOs will be granted at a price per share not less than the fair value of our common stock at the date of grant. Options granted generally vest over a four-year period; however, there might be alternative vesting schedules, as approved by the Board. Options granted, once vested, are generally exercisable for up to 10 years, after grant to the extent vested. In June 2019, the shareholders approved an amendment to the Company’s 2015 Plan for a one-time increase to the number of shares of common stock that may be issued under the 2015 Plan by 3,000 shares. On February 2, 2022, Sta nley Jacot, Jr. was hired as the new president and chief executive officer of the Company. The Company granted Mr. Jacot an inducement stock option to purchase 7,902 shares of the Company’s common stock pursuant to Rule 5635(c)(4) of the Nasdaq Listing Rules. The Company has filed a registration statement on Form S-8 to register the issuance of shares upon exercise of this inducement stock option. The inducement options grants have been issued outside of the 2015 Plan, but are subject to the terms and conditions of the 2015 Plan. As of September 30, 2023, a total of 86,834 shares of common stock were reserved for issuance under the 2015 Plan, of which 11,357 shares of common stock are available for future grant. As of September 30, 2023 , a total of 103 and 75,477 options are outstanding under the 2006 and 2015 Plans, respectively. As of December 31, 2022, a total of 103 and 51,421 options were outstanding under the 2006 and 2015 Plans, respectively. A total of 8,477 inducement options were outstanding as of September 30, 2023 and December 31, 2022. The following is a summary of stock option information and weighted average exercise prices under the Company’s stock incentive plans (in thousands, except share data and price per share): Shares Weighted- Aggregate Outstanding — Balance at December 31, 2022 60,002 $ 114.80 $ — Options granted 26,021 6.38 — Options exercised — — — Options forfeited ( 1,755 ) 32.02 39,062 Options expired ( 210 ) 118.35 — Outstanding — Balance at September 30, 2023 84,058 $ 82.71 $ — Vested and expected to vest — September 30, 2023 76,998 $ 87.65 $ — Exercisable — September 30, 2023 35,364 $ 143.59 $ — Aggregate intrinsic value represents the difference between the exercise price of the options and the estimated fair value of the Company’s common stock determined by its Board of Directors for each of the respective periods. As of September 30, 2023 , there was $ 833,000 of unrecognized compensation cost related to unvested stock-based compensation grants that will be recognized over the weighted-average remaining recognition period of 2.0 years. In determining the fair value of the stock-based awards, the Company uses the Black-Scholes option-pricing model and assumptions discussed below. Each of these inputs is subjective and generally requires significant judgment to determine. Expected Term— The expected term is the estimated period of time outstanding for stock options granted and was estimated based on a simplified method allowed by the SEC, and defines the term as the average of the contractual term of the options and the weighted-average vesting period for all open employee awards. Expected Volatility— The historical volatility data was computed using the daily closing prices for the Company’s shares during the equivalent period of the calculated expected term of the stock-based awards. Risk-Free Interest Rate— The risk-free interest rate is based on the interest rate of U.S. Treasuries of comparable maturities on the date the options were granted. Expected Dividend— The expected dividend yield is based on the Company’s expectation of future dividend payouts to common stockholders. The fair value of stock option awards was estimated at the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumption: Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 Expected term (years) — 5.69 7.06 6.41 Expected volatility — 122 % 124 % 122 % Risk-free interest rate — 2.99 % 3.61 % 2.59 % Dividend yield — — — — There were no option grants during the three months ended September 30, 2023. The Company recognized $ 162,000 and $ 573,000 of compensation expense for stock options awards during the three and nine months ended September 30, 2023 , respectively. The Company recognized $ 314,000 and $ 897,000 of compensation expense for stock options awards for the three and nine months ended September 30, 2022, respectively. Employee Stock Purchase Plan The Company’s 2015 Employee Stock Purchase Plan (“ESPP”) became effective on May 14, 2015. The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount of up to 15 % of their eligible compensation through payroll deductions, subject to any plan limitations. After the first offering period, which began on May 14, 2015 and ended on February 1, 2016 , the ESPP provides for six-month offering periods, and at the end of each offering period, employees are able to purchase shares at 85 % of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the last day of the offering period. As of September 30, 2023 , the number of shares of common stock reserved for future issuance under the ESPP is 7,265 . The ESPP provides for automatic annual increases in the shares available for purchase beginning on January 1, 2016. As of September 30, 2023 , 3,468 shares had been issued under the ESPP. The Company recorded $ 7,000 and $ 12,000 of ESPP related compensation expense during the three and nine months ended September 30, 2023 , respectively. The Company recorded $ 1,000 and $ 3,000 of ESPP related compensation expense for the three and nine months ended September 30, 2022 , respectively.

Income Tax Disclosure [Abstract]
Income Taxes	12. Income Taxes Income tax expense during interim periods is based on applying an estimated annual effective income tax rate to year-to-date income, plus any significant unusual or infrequently occurring items that are recorded in the interim period. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including, but not limited to, the expected operating income for the year, projections of the proportion of income earned and taxed in various jurisdictions, permanent and temporary differences, and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, more experience is obtained, additional information becomes known, or as the tax environment changes. The interim financial statement provision for income taxes is different from the amounts computed by applying the United States federal statutory income tax rate of 21 %. The Company’s effective tax rate was 0.00 % for each of the three and nine months ended September 30, 2023 and 2022. The difference between the effective tax rate and the federal statutory rate of 21 % was primarily due to the full valuation allowance recorded on the Company’s net deferred tax assets. During the nine months ended September 30, 2023 , there were no material changes to the Company’s uncertain tax positions. In February 2023, the Company received notification from the Internal Revenue Service that our Archipelago joint venture was selected for audit for the 2021 tax year. The Opening Conference was held on April 24, 2023. Management received the IRS agent’s Initial Document Request in April 2023 and has provided the documents requested. The Company is currently not under audit for state purposes.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	13. Commitments and Contingencies Leases The Company leases office and laboratory space, grain storage bins, warehouse space, farmland, and equipment under operating lease agreements having initial lease terms ranging from one to five years , including certain renewal options available to the Company at market rates. The Company also leases land for field trials on a short-term basis. See Note 8. Legal Matters From time to time, in the ordinary course of business, the Company may become involved in certain legal proceedings. The Company currently is not a party to any material litigation or other material legal proceedings. Contingent Liability Related to the Anawah Acquisition In June 2005 , the Company completed its agreement and plan of merger and reorganization with Anawah, to purchase the Anawah’s food and agricultural research company through a non-cash stock purchase. Pursuant to the merger with Anawah, and in accordance with the ASC 805 - Business Combinations, the Company incurred a contingent liability not to exceed $ 5.0 million. This liability represents amounts to be paid to Anawah’s previous stockholders for cash collected on revenue recognized by the Company upon commercial sale of certain specific products developed using technology acquired in the purchase. During 2010, the Company ceased activities relating to three of the six Anawah product programs thus, the contingent liability was reduced to $ 3.0 million. During 2016, one of the programs previously accrued for was abandoned and another program previously abandoned was reactivated. During 2019, the Company determined that one of the technologies was no longer active and decided to abandon the previously accrued program. As of September 30, 2023 , the Company continues to pursue or are otherwise liable for a total of two development programs using this technology and believes that the contingent liability is probable. As a result, $ 2.0 million remains on the condensed consolidated balance sheet as an other noncurrent liability. Contingent Liability Related to the ISI Acquisition In August 2020, the Company acquired by merger ISI. A portion of the purchase price consideration for the acquisition in the amount of $ 280,000 will be recognized in two annual installments, each of up to 3,316 shares of the Company’s common stock, subject to the achievement of revenue milestones in 2021 and 2022. The contingent consideration was measured and recorded at fair value. The contingent consideration liability was remeasured quarterly with changes in fair value recorded on the condensed consolidated statements of operations and comprehensive loss. During 2022, the contingent consideration liability was fully written down as the probability of achievement of the 2022 revenue milestone was remote. Contracts The Company has entered into contract research agreements with unrelated parties that require the Company to pay certain funding commitments. The initial terms of these agreements range from one to three years in duration and in certain cases are cancelable. The Company licenses certain technologies via executed agreements (“In-Licensing Agreements”) that are used to develop and advance the Company’s own technologies. The Company has entered into various In-Licensing Agreements with related and unrelated parties that require the Company to pay certain license fees, royalties, and/or milestone fees. In addition, certain royalty payments ranging from 2 % to 15 % of net revenue amounts as defined in the In-Licensing Agreements are or will be due. The Company could be adversely affected by certain actions by the government as it relates to government contract revenue received in prior years. Government agencies, such as the Defense Contract Audit Agency routinely audit and investigate government contractors. These agencies review a contractor’s performance under its agreements; cost structure; and compliance with applicable laws, regulations and standards. The agencies also review the adequacy of, and a contractor’s compliance with, its internal control systems and policies, including the contractor’s purchasing, property, estimating, compensation and management information systems. While the Company’s management anticipates no adverse result from an audit, should any costs be found to be improperly allocated to a government agreement, such costs will not be reimbursed, or if already reimbursed, may need to be refunded. If an audit uncovers improper or illegal activities, civil and criminal penalties and administrative sanctions, including termination of contracts, forfeiture of profits, suspension of payments or fines, and suspension or prohibition from doing business with the government could occur. In addition, serious reputational harm or significant adverse financial effects could occur if allegations of impropriety were made against the Company. There currently are routine audits in process relating to government grant revenues.

Earnings Per Share [Abstract]
Net Loss per Share	14. Net Loss per Share Basic net loss per share is calculated by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period and excludes any dilutive effects of stock-based awards and warrants. Diluted net loss per share attributable to common stockholders is computed giving effect to all potentially dilutive common shares, including common stock issuable upon exercise of stock options and warrants. Dilutive securities are not included in the computation of net loss per share when the impact would be anti-dilutive. Securities that were not included in the diluted per share calculations because they would be anti-dilutive were as follows (in shares): For the Three and Nine Months Ended September 30, 2023 2022 Options to purchase common stock 84,058 60,044 Warrants to purchase common stock 266,957 283,751 Preferred investment options 1,489,952 123,966 Total 1,840,967 467,761

Related-Party Transactions	15. Related-Party Transactions The Company’s related parties include Moral Compass Corporation (“MCC”) and the John Sperling Foundation (“JSF”). The rights to the intellectual property owned by Blue Horse Labs, Inc. (“BHL”) were assigned to its sole shareholder, the John Sperling Revocable Trust (“JSRT”) due to BHL’s dissolution and then subsequently to the JSF. The JSF is deemed a related party of the Company because MCC, the Company’s largest stockholder, and the JSF share common officers and directors. JSF receives a single digit royalty from the Company when revenue has been collected on product sales or for license payments from third parties that involve certain intellectual property developed under research funding originally from BHL. Royalty fees due to JSF were $ 46,000 and $ 48,000 as of September 30, 2023 and December 31, 2022 , respectively, and are included in the condensed consolidated balance sheets as amounts due to related parties.

Accounting Policies [Abstract]
Organization	Organization Arcadia Biosciences, Inc. (the "Company," "Arcadia" or "management"), was incorporated in Arizona in 2002 and maintains its headquarters in Dallas, Texas, with additional office space in Davis and Sacramento, California, and additional facilities in American Falls, Idaho. The Company was reincorporated in Delaware in March 2015 . The Company is a producer and marketer of innovative, plant-based food and beverage products. Its history as a leader in science-based approaches to developing high-value crop improvements, as well as nutritionally enhanced food ingredients, has laid the foundation for its path forward. The Company used advanced breeding techniques to develop these proprietary innovations which are now being commercialized through the sales of seed and grain, as well as food ingredients and products. The acquisition of the assets of Live Zola, LLC (“Zola”) added coconut water to the Company's portfolio of products. In May 2021, the Company’s wholly owned subsidiary Arcadia Wellness, LLC (“Arcadia Wellness” or “AW”) acquired the businesses of Eko, Lief, and Zola. The acquisition included consumer CBD brands like Soul Spring™, a CBD-infused botanical therapy brand in the natural category, Saavy Naturals™, a line of natural body care products and ProVault™, a CBD-infused sports performance formula made with natural ingredients, providing effective support and recovery for athletes (collectively "body care brands"). Also included in the purchase was Zola, a coconut water sourced exclusively with sustainably grown coconuts from Thailand. In August 2019, the Company entered into a joint venture agreement with Legacy Ventures Hawaii, LLC (“Legacy,” see Note 6) to grow, extract, and sell hemp products. The partnership Archipelago Ventures Hawaii, LLC (“Archipelago”), combines the Company’s extensive genetic expertise and resources with Legacy’s experience in hemp extraction and sales. In October 2021, Arcadia and Legacy mutually agreed to wind down the cultivation activities of Archipelago, due to regulatory challenges and a saturated hemp market. In February 2012, the Company formed Verdeca, which was equally owned with Bioceres. Verdeca was formed to develop and deregulate soybean varieties using both partners’ agricultural technologies. In November 2020, Arcadia sold its membership interest in Verdeca to Bioceres in a transaction in which Arcadia received cash, shares of Bioceres stock and a royalty stream of up to $ 10.0 million on sales of Haab 4 soybeans (“HB4”). An additional $ 2.0 million in cash is to be paid upon achievement by Verdeca of reaching commercial plantings of at least 200,000 hectares of HB4 or China approving the HB4 soybean trait for “food and feed”. During 2022, Bioceres received China's approval of the HB4 soybean trait and as a result, Arcadia recorded license revenue of $ 862,000 and a gain on sale of Verdeca of $ 1.1 million on the condensed consolidated statements of operations and comprehensive loss. The Company received the full payment of $ 2.0 million as of September 30, 2023.
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial statements and are in the form prescribed by the Securities and Exchange Commission (the “SEC”) in instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, the accompanying condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the periods indicated. All material intercompany accounts and transactions have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements include the accounts of the Company, Arcadia Wellness, and Archipelago. The Company uses a qualitative approach in assessing the consolidation requirement for variable interest entities ("VIEs"). This approach focuses on determining whether the Company has the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and whether the Company has the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the VIE. For all periods presented, the Company has determined that it is the primary beneficiary of Archipelago, a joint venture, as it has a controlling interest in Archipelago. Accordingly, the Company consolidates Archipelago in the condensed consolidated financial statements after eliminating intercompany transactions. For consolidated joint ventures, the non-controlling partner’s share of the assets, liabilities and operations of the joint venture is included in non-controlling interests as equity of the Company. The non-controlling partner’s interest is generally computed as the joint venture partner’s ownership percentage of Archipelago. Net loss attributable to non-controlling interest of $ 10,000 and $ 152,000 is recorded as an adjustment to net loss to arrive at net loss attributable to common stockholders for the three and nine months ended September 30, 2022, respectively. There was minimal activity during the three and nine months ended September 30, 2023. The non-controlling partner’s equity interests are presented as non-controlling interests on the condensed consolidated balance sheets. The information included in these condensed consolidated financial statements and notes thereto should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations included herein and Management’s Discussion and Analysis of Financial Condition and Results of Operations and the condensed consolidated financial statements and notes thereto for the fiscal year ended December 31, 2022 included in the Company’s Annual Report on Form 10-K, filed with the SEC on March 30, 2023.
Reclassifications	Reclassifications Certain previously reported financial information has been reclassified to conform to the current year presentation. For a discussion of the reclassification of the financial presentation of our former body care brands reported as discontinued operations, see “Discontinued Operations” section below. Unless otherwise noted, amounts and disclosures throughout these notes to condensed consolidated financial statements relate solely to continuing operations and exclude all discontinued operations.
Reverse Stock Split	Reverse Stock Split In February 2023, the Company’s board of directors approved a reverse split of 40:1 on the Company’s issued and outstanding common stock. On F ebruary 15, 2023, the Company’s stockholders approved the certificate of amendment, which the Company filed on February 27, 2023 with the Secretary of State of Delaware to effect the reverse split on March 1, 2023. As a result of the reverse stock split, additional shares of common stock of 19,118 were issued in lieu of fractional shares. All issued and outstanding common stock, options to purchase common stock and per share amounts contained in the condensed consolidated financial statements have been retroactively adjusted to reflect the reverse stock split for all periods presented.
Liquidity, Capital Resources, and Going Concern	Liquidity, Capital Resources, and Going Concern The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities during the normal course of business. Since inception, the Company has financed its operations primarily through equity and debt financings. As of September 30, 2023, the Company had an accumulated deficit of $ 269.0 million, cash and cash equivalents of $ 10.6 million and short-term investments of $ 5.1 million. For the nine months ended September 30, 2023, the Company had net losses of $ 11.1 million and net cash used in operations of $ 11.1 million. For the twelve months ended December 31, 2022, the Company had net losses of $ 15.6 million and net cash used in operations of $ 14.0 million. With cash and cash equivalents of $ 10.6 million and short-term investments of $ 5.1 million as of September 30, 2023, the Company believes that its existing cash, cash equivalents and short-term investments will not be sufficient to meet its anticipated cash requirements for at least the next 12-18 months from the issuance date of these financial statements, and thus raises substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. The Company may seek to raise additional funds through debt or equity financings. The Company may also consider entering into additional partner arrangements. The sale of additional equity would result in dilution to the Company’s stockholders. The incurrence of debt would result in debt service obligations, and the instruments governing such debt could provide for additional operating and financing covenants that would restrict operations. If the Company requires additional funds and is unable to secure adequate additional funding at terms agreeable to the Company, the Company may be forced to reduce spending, extend payment terms with suppliers, liquidate assets, or suspend or curtail planned product launches. Any of these actions could materially harm the business, results of operations and financial condition.
Discontinued Operations	Discontinued Operations In July 2023, management made the decision to exit its body care brands as a result of continued pressure on the CBD market due to regulatory uncertainty. This decision will streamline the business and allow the Company to focus on growth of the its other “core” brands, which consist of the GoodWheat portfolio and Zola. Body care operations ceased as of September 30, 2023. In accordance with the provisions of ASC 205-20, the Company has separately reported the assets and liabilities of the discontinued operations in the condensed consolidated balance sheets and the results of the discontinued operations as a separate component of income on the condensed consolidated statements of operations and comprehensive loss for all periods presented.
