American Eagle Design Build Studios, LLC (AEDBS) and Southeastern Stud & Components, Inc. (SES) entered into a Subcontract Work Agreement (Subcontract), which contained an arbitration clause. After a dispute arose, SES filed a lawsuit against AEDBS. Over a year after SES first filed its complaint, AEDBS filed a motion to compel arbitration. The district court 1 denied AEDBS’s motion to compel arbitration, and AEDBS now appeals. For the following reasons, we affirm.
I.
AEDBS was the prime contractor constructing housing on an Air Force base in Little Rock, Arkansas. On August 23, *966 2006, SES and AEDBS entered into the Subcontract, which stated that SES was to provide labor and materials to the housing project. The Subcontract contained an arbitration clause that said, “[a]ny dispute between [SES] and [AEDBS] arising out of this Agreement or breach thereof, ... may, at the option of [AEDBS], be submitted to arbitration.” (J.A. at 486-87.)
A dispute arose involving payment for work performed under the Subcontract. On June 26, 2007, SES filed suit against AEDBS and several other parties. AEDBS did not move to compel arbitration at that time but, over the course of the following year, answered SES’s complaint, filed responses and objections to SES’s request for production of documents and filed a motion for judgment on the pleadings without raising the issue of arbitration. AEDBS claims that during this period it did not believe it could enforce the arbitration agreement under Arkansas law. On July 15, 2008, SES filed a second amended complaint. At that point, following an unpublished decision by the United States District Court for the Eastern District of Arkansas, AEDBS asserts that it believed it could enforce the arbitration agreement. In its July 29, 2008, answer to AEDBS’s second amended complaint, AEDBS raised arbitration as an affirmative defense, and on September 3, 2008, AEDBS filed a motion to compel arbitration. Before the district court, SES argued that the arbitration clause was unenforceable because: (1) there was no mutuality of obligation as the decision to enforce the arbitration clause was left entirely to AEDBS; (2) AEDBS had waived its right to arbitration by participating in the litigation; and (3) SES would be prejudiced by the arbitration.
The district court denied AEDBS’s motion to compel arbitration, finding that while the arbitration clause was enforceable despite its lack of mutuality, AEDBS had waived its right to arbitration and SES would be prejudiced by the arbitration. AEDBS appeals, arguing that it did not waive its right to arbitrate the agreement by participating in the litigation.
II.
In reviewing the district court’s determination that AEDBS waived its right to arbitrate the agreement, “[w]e review de novo the legal determination of waiver but examine the factual findings underlying that ruling for clear error.”
Lewallen v. Green Tree Servicing, L.L.C.,
We note that there is a “ ‘strong federal policy in favor of arbitration,’ ” such that “ ‘any doubts concerning waiver of arbitrability should be resolved in favor of arbitration.’ ”

(quoting
Dumont v. Saskatchewan Gov’t Ins.,
AEDBS asserts that, at the time SES filed its complaint against AEDBS, it did not believe that it had the right to arbitrate. According to AEDBS, before March 2008, Arkansas law required mutuality of obligation within the contract’s arbitration agreement, even if there was sufficient mutuality within the rest of the contract.
See Showmethemoney Check Cashers, Inc. v. Williams,
However, as early as 1984 the Supreme Court held that the Federal Arbitration Act (FAA) “preempts a state law that withdraws the power to enforce arbitration agreements.”
Southland Corp. v. Keating,
AEDBS points to
Ackerberg v. Johnson,
AEDBS argues that, like the defendants in Ackerberg, it did not waive its right to arbitrate because it asserted its right to arbitrate “the very day it learned of Enderlin’s precedential support for the enforcement of its Arbitration Agreement with SES” (Appellant’s Br. at 23), and because any motion to compel arbitration prior to Enderlin would have been futile. However, as discussed above, even prior to Enderlin the law was clear that Arkansas could not have imposed additional requirements that applied only to arbitration agreements. Thus, Enderlin did not decide new law or reverse previous case law as Rodriguez de Quijas did. Instead, as explained above, it merely correctly applied existing law. Contrary to what AEDBS claims, a motion to compel arbitration prior to Enderlin would not have been futile ab initio. Thus, AEDBS’s reliance on Ackerberg is misplaced. Accordingly, AEDBS knew of its contractual right to arbitration when SES filed the lawsuit in June 2007.
Second, AEDBS acted inconsistently with its existing right to arbitrate. “A party acts inconsistently with its right to arbitrate if the party ‘[substantially invoke[s] the litigation machinery before asserting its arbitration right.’ ”
Lewallen,
Third, SES was prejudiced by AEDBS’s acts that were inconsistent with exercising its right to arbitration. “A party is so prejudiced when the ‘parties use discovery not available in arbitration, when they litigate substantial issues on the merits, or when compelling arbitration would require a duplication of efforts.’ ”
Id.
at 1093 (quoting
Kelly v. Golden,
Because AEDBS had knowledge of its existing right to arbitrate but acted inconsistently with that right and prejudiced SES by those actions, AEDBS waived its right to arbitration.
See Lewallen,
III.
Accordingly, the judgment of the district court is affirmed.
